Change into casual clothes and go straight to Liulizhai.

Yang Reform is directly on Sun Liniang's boudoir.

"Liniang, Liniang, I've come to see you." Yang Gengai shouted.

"Childe ......" Sun Liniang also got the news and was waiting for Yang to reform.

"Hehe, Li Niang, I miss me." As soon as Yang Reform saw Sun Liniang, his heart itched.

"Childe sit down, Liniang will pour tea for Childe." Sun Liniang poured tea for Yang Reform very enthusiastically.

Yang Reform sat down and looked at the layout of the house, adding a lot of glass decorations, decorating it very warmly, Yang Reform said while looking: "Li Niang, I want to tell you something today." "The most important purpose of Yang Reform's coming today is to hand over the wool business to Tian Hongyu.

"Childe, what's the matter?" Sun Liniang was making tea for Yang Reform, and when she heard Yang Reform say that there was something, she immediately asked what was the matter, her expression was gentle, and she smiled with a happy look.

“…… Yes! Yes! This, this! ......" Yang Gai suddenly found Sun Liniang with a happy smile, she couldn't speak about this matter, and asked her to transfer the business to Tian Hongyu, didn't she say that she didn't trust her ability? Isn't that a blow to her? Yang Gai couldn't bear to watch Sun Liniang being wronged and shed tears.

"By the way, Childe, the glass tube that Childe explained to make last time has already been made a lot, Liniang will show Childe." Sun Liniang said happily, since the last time the emperor asked him to make that kind of glass tube, Liulizhai immediately used a lot of masters, specifically for the emperor to make this kind of thing, this kind of thing, the first half of the cut is easy to do, to the second half, it is not easy to do, the first half is formed and then pour the liquid into the glass tube, the second half is to completely seal the glass tube, the difficulty is here.

"Good! I'd love to see it. "Yang Gengzheng doesn't know how to talk about the wool thing, but now that he has a thermometer, he won't be speechless.

“…… It's done, but it's harder! I don't do much to do it, so please don't be surprised. Sun Liniang explained.

"Is it hard? What's the difficulty? …… Let's see how it goes? Yang Gai said, this glass can be made, this thermometer is not a piece of cake?

"Okay, childe, Liniang will go get ......" Sun Liniang didn't think much about it, and immediately went to get the finished thermometer.

…… After a while, Sun Liniang came with some glass tubes. Said: "Childe, this kind of hot and cold thing, the first half is easy to do, and the second half is not easy to do, according to the speed of our Liulizhai, it could have been done a long time ago, but because the second half is difficult to do, it is really ......, so what is done now is only these...... Sun Liniang explained.

"Oh? Is it? Why is the first half of the cut so good? Is it difficult to do the second half? Yang Gengai picked up a glass tube and looked at it, the lower half was very smooth, very good, but the place where the top seal was burned crookedly, not very natural, upside down, there was no leakage, and the liquid in the glass tube was sealed.

"Childe, according to Childe's instructions, Liniang chose a lot of things that can flow and tried, and found that a lot of liquids are obviously ...... to the changes in cold and heat, but the mouth is not easy to seal, such as wine, vinegar, oil, and even water, as soon as you get close to the furnace that melts glass, the water in the glass tube will be baked all at once. The craftsmen have been busy many times, and they have not done it very well, the liquid in the glass tube is either too much, or it is baked, and the craftsmen can't, so they only do these ......" Sun Liniang whispered that it is easier for the glass to melt, but it is difficult to melt the mouth and seal the mouth after loading things in the glass tube, and the things in the glass tube are easily roasted by high temperature, or the remaining amount is different.

"And this?" Yang Reform wondered, sure enough, the thermometer belongs to a relatively high technology, and it is not so simple to get it, so how did the later people get it?

"Yes! Childe, you see, the liquid in these made is either more or less, and it is difficult to achieve the same amount as Childe said,...... However, these glass tubes are made, put in hot water, the hotter they are, the more the liquid in the glass tube rises, which is really interesting...... Liniang recorded the concentrated rise more obviously...... Here, it's a pity that it's really difficult to be consistent...... "Although Sun Liniang has done a lot of thermometers, it is a pity that she did not complete the task perfectly, and she did not ask for credit in front of Yang Reform.

"It's hard to keep your mouth shut, I want to think about it,...... Are these sensitive to heat and cold? ...... "Yang Reform didn't have any good ideas for a while, I don't know what process to use to seal the mouth of the thermometer, too close to the heat source, the things in the glass tube, it is easy to volatilize, and it is indeed a problem to make a thermometer with a unified standard."

Yang Gengai fiddled with those glass tubes, and sure enough, the labels on them indicated all kinds of liquids, including water, oil, vegetable oil, tung oil, tea oil, lard, soy sauce, ......, vinegar and white vinegar of Lao Li's family, and old Chen's vinegar.

A wave of glass tubes, a large category put together, a lot of oil, several vinegar, a lot of wine, there are a lot of wine ......, there are actually quite a lot of things...... Yang Gengai picked up a glass tube marked with mercury and said, "Have you put this thing in too?" "It's mercury! A large part of the thermometer is later, but it is a mercury thermometer. Yang Gai saw it and was excited!

"Yes! Childe, Li Niang saw that this mercury can also flow, according to Childe's instructions, to exhaust the things that can flow in the world, and also put a few of this, but this kind ......of thing is poisonous, very difficult to get, and easy to distribute, a little careless, the mercury in the glass tube is gone, and for this reason, it also injured several masters. Sun Liniang is very concerned about the emperor's matter, and she has enough understanding of the specific production process.

"Not bad, not bad!" Yang Gai was very satisfied, but he didn't expect that in the seventeenth century, he could also see the demeanor of the mercury thermometer, which was really a happy thing, so he immediately put the mercury thermometer in his arm, ready to see what his body temperature was.

"Childe, Childe, what are you?" Sun Liniang was very curious when she saw Yang Reform holding the hot and cold thing between her arms and asked Yang Reform what she was doing.

"Hehe, Li Niang, didn't I tell you? This kind of thing, Ben Gongzi is going to call it a thermometer, used to measure heat and cold, to measure the temperature of people, with it, whether the patient is cold or feverish, to what extent cold, to what extent is fever, isn't it clear at a glance? Yang Gai said excitedly, this is a big step forward in the history of medicine!

Sun Liniang looked at Yang Reform fiddling with the thermometer suspiciously, and still didn't understand very well, and asked, "Childe, what is temperature?" …… Also, what kind of thermometer is this, each one is made differently, some are filled with more mercury, some are filled less, even if there is a change after the heat, the change of each glass tube must be different! How can this be identified? Also, even if the mercury in this glass tube changes, how do you know if it is a normal person? Sun Liniang asked a lot of questions, and they kept being thrown, and Yang Reform originally wanted to explain what a thermometer was, but he didn't have a chance to speak.

“…… Oh ......, Liniang knows, is it with a ruler, use a ruler to measure, how much mercury in the glass tube has risen, so that you can know whether the patient is hot or cold, how much hot, or how cold? …… For example, if a normal person rises to an inch and stops, it means that one inch is normal, if the patient is given a measure of cold and heat, and it does not reach an inch, it is cold, according to the difference of one inch, determine how much it is cold, if the difference is two points, then say: cold two points, if it is longer than one inch, then say: one point longer; Hot for a minute...... And so on, childe, is Liniang very reasonable......" Sun Liniang asked happily, this is Sun Liniang who has nothing to figure out these days, the emperor asked her to exhaustively raise the thermometer, she has made a lot, but there are also many problems, first, each thermometer is different, the amount of liquid in the glass tube, how much or less, second, the emperor wants to use this thing to measure people's heat and cold, for how to measure, Sun Liniang thought about breaking her head, and finally came up with a more reliable method, That is, first use a ruler to measure the scale of a normal person, such as an inch, then, if the patient is a fever, the liquid in the glass tube must rise more than an inch, if it rises by one point, then, it is an inch by one, then, you can determine that the patient has a fever, it is called a ...... of one point, Sun Liniang feels that only by her own method can she accurately find out whether the patient is cold or hot, how much cold, how much hot...... Belch! …… Yang Gai looked at his woman in surprise, but he didn't see that his woman not only has business acumen, but also has the mind of a scientist, and it is a pity not to be a scientist. I can come up with this method, but I am ready to "confess", the calculation method of the thermometer is: the ice water mixture is zero degrees, and the boiling water is one hundred degrees...... Yang Reform could only look at his woman with surprised eyes, this woman is not simple! I don't know what to say, the matter of handing over the wool business, Yang Reform is even more embarrassed to speak.

Sun Liniang saw her son-in-law looking at her with surprised eyes, and felt that the method she had come up with was very effective, so she smiled coquettishly: "Hehe...... How's that, Childe, isn't Liniang smart? Hehe...... Come on, come on, see if Childe is cold or hot...... whether it is hot or cold, the little woman should also be a doctor, and treat Childe ......" Sun Linian was very happy and played, pretending to pull out the mercury thermometer from Yang Reform's armpit.

"Oops...... It's amazing! Childe, you have a terrible fever! Look, it's an inch and a half, and it's burned for five minutes! Oops...... It's amazing, it's amazing! Childe, you have to find a doctor quickly......" Sun Liniang pretended to measure the thermometer with a ruler, and then pretended to be surprised.

Yang Gai couldn't cry or laugh, he was so shocked that he said with a smile: "Where is there a fever to this extent, the lady is not mistaken." Yang Gengai also laughed.

"Childe, where is it wrong, look, it's obviously an inch and a half, it's clearly not ......wrong," Sun Liniang said coquettishly. even pretended to hold a ruler and gesture to the mercury thermometer, with such a correct expression.

Yang Gengai was very embarrassed, played with Sun Liniang for a while, and said with a smile: "Hehe, Liniang, I'll teach you a better way to determine how to measure hot and cold." ”

"Childe, what is that going on?" Sun Liniang asked curiously, in her opinion, the internal space of each glass tube is of different sizes, and the amount of liquid contained in it is different.

"Hehe, this method is also very simple, you put the end of the thermometer with a vacuole, put it in a mixture of ice and water for a period of time, first assume that it is zero degrees, and then put the vacuole of this thermometer into the boiling water for a time, and set the position of the liquid in the glass tube to 100 degrees, so that between zero and 100 degrees, divided into 100 scales, isn't this more accurate? As long as others get the thermometer, they can measure the heat and cold of the human body anytime and anywhere? If you think that the body temperature of normal people is about the same, there should be a fixed scale, and then by collecting the results of many people's measurements, you should be able to get a relatively average scale, and then take this scale as the standard, set this scale as the normal body temperature of the human body, take this thermometer made in advance, and if it is higher than the average scale, it is a fever, or a high fever of one degree, or a high fever of two degrees, so that you can distinguish the serious surname of the disease, so as to identify the ...... of the disease." Yang Gai did not hesitate to use the division method of the Celsius thermometer in the future, which is relatively intuitive and simple, and is also suitable for his own situation today.

This time, it was Sun Liniang's turn to be surprised, Sun Liniang thought about it carefully, and felt that the emperor's idea was a hundred times better than hers, indeed, in this way, to measure whether a person is cold or feverish, how cold it is, how much fever it is, there is indeed a more intuitive scale, which is indeed quite helpful for judging the condition, and more importantly, in this way, it has nothing to do with the amount of liquid in the glass tube. All glass tubes should be measured on a 30% scale.

Sun Liniang said with an expression of surprise and admiration: "Childe's method is a hundred times that of Ming Liniang, it is indeed a good way!" ”

"Hehe...... so-so, so-so, so-so!" Yang's reform is even more difficult! This is **naked plagiarism, but it is not my own idea, Yang Reform's cheek, and his face is blushing.

“…… Oh, that is to say, Childe, to make this kind of thermometer, when making it, fill the liquid finger puppet, first soak the glass tube in ice water? Then make a mark, then go to the boiling water, make a mark, and finally seal it? In this way, although the liquid of each glass tube is different and the amount is different, the scale is equal, so that there will be no mistakes......" Sun Liniang began to think about how to do things according to the emperor's ideas.

"Well, that's probably the case......" Yang Reform didn't know how the thermometer was made, but after listening to what Sun Liniang said, it was estimated that it was right, probably right.

"By the way, Childe, it's still the problem of sealing, if it is marked in boiling water, if it is transferred to the furnace to seal, the liquid in the glass tube, I'm afraid there will be changes again! The stove is too hot, put the glass tube close to the stove to seal, and the liquid in the glass tube will dry out at once, even if there is a stopper, it is very difficult...... In this way, have not all the previous things been done in vain? Sun Liniang remembered the problem of difficulty in sealing again.

Hiss......, Yang Reform was also confused, this is indeed a problem, this mercury, alcohol and other liquids, at room temperature are very volatile, when encountering high temperatures, it is more volatile, to seal the glass mouth, this action must be completed in a very short time, to let the liquid in the glass tube, there is no time to escape out of the glass tube, but, obviously, the glass-burning furnace is so hot, wait for you to send the glass tube over, the liquid in the glass tube, I'm afraid there won't be much left, stopper? , Yang Reform suddenly remembered that Sun Liniang's test items were still oil, and when he thought of sending the glass tube filled with oil to a furnace that could melt the glass and seal it, Yang Reform felt that this thing was really not something that ordinary people could do, and those craftsmen who were responsible for sealing it were afraid that they would have to find a way!

Yang Reform felt that he really had to think of a safer way to solve this problem for his woman, and when he thought of the scene that might even explode, Yang Reform was afraid for a while, but fortunately his woman didn't try it.

"Then why don't you tell the workers to seal their mouths first, and then engrave the scale?" Sun Liniang asked again.

"This ......" Yang Reform is in difficulty, for the thermometer, Yang Reform is the shopkeeper who shakes his hands, the specific details, I don't know at all, Sun Liniang, who has no experimental experience, knows a lot, and now Sun Liniang asks, it is also blind.

It is best to use a very high temperature to seal the mouth of the glass tube as quickly as possible, which can not be preheated in advance, and it is best to do it at room temperature, so as to avoid the liquid in the glass tube from volatilizing and affecting the measurement accuracy of the thermometer.

Yang Gengai thought about it, remembered it, and watched TV later, as if he had seen a kind of equipment, which was used to seal the glass bottle of the charge, and it seemed to be used as if it was ...... The blue flames that erupted...... Yang Reform suddenly remembered that yesterday was the day before yesterday, and he seemed to see this kind ......of thing, by the way, the kind of thing that burns pig's hair after the re-blowtorch, yes, it is a blowtorch, which is now a fierce fire oil tank! Yang Reform suddenly realized that the principle of the fierce fire oil cabinet used today is exactly the same as the blowtorch that burns pig hair after the release, and the equipment for the sealing of the drug delivery bottle seems to be also a blowtorch, that is to say, the sealing of the glass is done with a blowtorch, and he can let the guys who are engaged in the fierce fire oil cabinet get some blowtorches out, so that it should be able to meet the needs of quickly sealing the mouth of the glass tube at room temperature...... Thinking of this, Yang Gengai exclaimed excitedly, "Oops...... I thought about it, I thought about it!" ”

Sun Liniang, who was still meditating, asked, "What do you remember?" Son? ”

"Li Niang, I thought of a thing that can instantly seal the mouth of the glass tube without a stove! In this way, the things in the glass tube have not changed at all, you make a thermometer, and in the future, you can seal the mouth of the glass tube first, or you can carve the scale of the thermometer first, it's all up to ......you," Yang Genghe thought.

"Really? Son? And this thing? Why has Liniang never heard of it? Sun Liniang asked in disbelief. What melts glass instantly? You know, it's not easy to burn glass, you have to burn it in a furnace with a big fire, and if anything can melt the glass in a very short time, what a fierce fire!

"Hehe...... this is absolutely true, there are many capable people in my son's family, and there are those who specialize in this, hehe, you will know it later, the package is easy to use...... "Yang Reform now dares to pack tickets. How to seal the glass, Yang Reform said that after Yang reformed, he had seen the machine that sealed the glass bottle, a row of flames sprayed out, the mouth of the glass bottle was sealed in an instant, and the medicine in the glass bottle was intact, as long as he asked those craftsmen to change the fierce fire oil cabinet into a blowtorch, isn't this a piece of cake? If you don't have kerosene, you can use lamp oil, vegetable oil, or even other oils instead, and if you can't do it, you can refine some alcohol yourself, it's enough, anyway, the thermometer won't have to be made tens of thousands at a time.

"Really? Then Liniang won't be worried......" Sun Liniang looked at Yang Reform with a happy face. Sun Liniang knows that her son-in-law is the emperor, and there are many skilled craftsmen in the world, and if you want to say that there is such a thing, it will not be fake.

The problem of the thermometer is solved, however, the purpose of Yang Reform's coming today is to let Sun Liniang hand over the wool business to Tian Hongyu to do, Yang Reform at this time, even more embarrassed to speak, looking at this wife who is busy with herself and trying to help herself in every way, to let her hand over the business, this is probably a big blow to her, which hurts her heart a lot...... "...... Hey...... this, Liniang! I thought about it, this thermometer, after the scale is unified, has the function of measuring cold and heat, it will definitely benefit the people of the world and achieve a good reputation. This Qin Shi Huang is the achievement of the unification of the world, but also the unification of weights and measures and famous, however, he did not work out how to measure hot and cold a standard, did not develop a measure of hot and cold, I think, can be measured by this thermometer as a standard, formulate a standard and law to measure hot and cold, measure the length is called length, this measure of hot and cold, it is called temperature, the tool for measuring temperature, just is a thermometer, and degrees, measurements, and weights and balances have become a law that passes the world...... , Li Niang, the mention and invention of this temperature belongs to you, and where the temperature is used in the future, you must be mentioned, and it must be recited for all generations! ...... "Yang Reform was embarrassed to mention the wool to Sun Liniang, for fear of hurting Sun Liniang's heart, so he gave Sun Liniang a good news first, and prepared to use this good news as a foundation, and when he opened his mouth about wool, he would not be embarrassed."

To set a standard and define temperature, so that temperature becomes one of the legal weights and measures, Yang Reform used me to show the solemnity of this matter.

(To be continued)
