"Look, 50 mm caliber magnifying glass, F quarter." Lin Hanlong took out the magnifying glass and handed it to Wu Nanhai. Wu Nanhai casually picked up the writing paper on the table and looked at it with a magnifying glass.

"Well, well done. It's clear. Wu Nanhai sighed, and stroked the handle of the magnifying glass with his hand, "If it weren't for this wooden handle, I would have thought we brought it." ”

"High-end magnifying glasses are mostly made of natural materials, and wood is just one of them."

Wu Nanhai put down the magnifying glass and nodded. "Okay, absolutely. Our agricultural sector is doing as much as possible for this kind of stuff. He turned back to the naturalized staff and said, "Go, bring the bill of lading and let them go through the delivery procedures." ”

"Very well, so that the two are clear."

"By the way, the saccharimeter I mentioned last time, you said it was done?" Saying this, Wu Nanhai's voice became solemn, this is the real purpose of his coming.

"Oh, that." Lin Hanlong took out a box from the drawer with a nonchalant look. "It's made one. Look. ”

A saccharimeter is a rapid detection instrument that uses optical principles to quickly determine the concentration or refractive index of sugary solutions and other non-sugar solutions. It plays an important role in industrial and agricultural production fields such as sugar, food and beverages. In addition to measuring sugar content, it can also be used to measure the concentration of various sauce products such as soy sauce and ketchup. In agricultural production, it is suitable for determining the accurate harvest period on fruits and sugar crops, and grading and classifying sweetness.

The principle is that when light rays enter from one medium to another, the phenomenon of refraction occurs, and the ratio of the incidence angle sine is constant and constant, and this ratio is called the refractive index. The content of soluble solids in fruit and vegetable juice is proportional to the refractive index at the same temperature and pressure, and the concentration of fruit and vegetable juice can be found by measuring the refractive index of fruit and vegetable juice.

The saccharimeter that Wu Nanhai took out was basically like a sugar cane with a diagonal cut at one end, the pointed end was inlaid with glass, and there were a few knobs at the end of the cylinder. Wu Nanhai picked up the Brix meter and brought it to his eyes, pointed the tip to the light, and adjusted the knob with his fingers. He turned to Lin Hanlong, "Old Lin, I'm sorry I want to take a look." ”

Lin Hanlong nodded. "And rightfully so."

Wu Nanhai turned his head. "The beginning of the sunshine! Bring the bottles. ”

The bottle is filled with water, and there is also haode sugar water in different proportions. Wu Nanhai first dripped a few drops of water on the glass, and then adjusted the knob. Lin Hanlong handed over a flannel cloth on the side, Wu Nanhai took it and wiped off the water droplets, and then dripped sugar water. He squinted at the light for a moment, then wiped off the sugar water, replaced the bottle and added a few drops. Repeating this a few times, he put the Brix meter down and exhaled.

"Lao Lin, you are really good! This stuff is very well done, and the sugar content measurement is accurate. Wu Nanhai was already smiling at this time. Very good, very good. I want as much as I want this thing. I'll have someone report it when I get back. ”

Lin Hanlong nodded. "You just sign the list, go back and stamp the seal of the Committee of Agriculture. This sample can be taken now. He took out a wooden box from the drawer, opened it and handed it to Wu Nanhai, "The matching box." ”

"The lenses in this are mass-produced, no problem. But the prism is ground by hand. Mass production has to wait for the surface grinder to come out. ”

"Oh, how long will it take? I plan to send a batch before the next crushing season, and I will teach them to use it in advance. ”

"That's for the Navy. The binoculars they were in a hurry, saying that they were going to fit two of them on each boat. ”

"That's how much! Sucrose is an important source of income for us, and we can't lose it. Wu Nanhai said urgently. He was also forced by Wen Tong to be anxious -- Wen Tong promoted sugarcane production combinations in Leizhou, engaged in the cultivation of improved varieties, and the rotation of prices according to quality was a major link in Leizhou's sugar policy, and without a sugar meter, the rules and regulations formulated by Wen Tong could not be concretely implemented.

"Who's to say it isn't." Lin Hanlong echoed casually, but there was no specific indication

Wu Nanhai came to his senses: "Let me help you tell the executive committee that the optical instrument is too important, and it is necessary to increase investment." ”

"You're out of the horse, a top one."

"hahahahahaha......ha

"It's a new cigar from the farm, you can try it." "No, no, I haven't finished the limited edition you gave me last time...... Lin Hanlong politely.

"Try something new. This time it's a limited edition of Li Quan. Wu Nanhai smiled, "You taste it, the tobacco leaves are made from Macao by the Jesuits I asked the Jesuits, and the real Caribbean is made of wrappers." ”

Lin Hanlong thought for a long time before remembering who Li Quan was, and he smiled and took the box. The box is made of a precious wood that exudes a faint woody scent. According to Wu Nanhai, timber is also imported from Southeast Asia. The white-woodened lid was branded with black lettering—and even in extra-curricular script that he didn't recognize. The box also has a green stamp with the words "tax exemption" from the Monopoly Bureau of the Department of Finance. It looks magnificent.

In contrast, the last limited edition was nothing more than cardboard packaging. Needless to say, which is more advanced. Lin Hanlong found that the packaging description of Li Quan's limited edition was "three branches", and he couldn't help but secretly scolded Wu Nanhai for becoming more and more profiteers.

"Not bad, not bad." He also played haha. Wu Nanhai took out two more glass bottles from his pocket.

"This is a fruit wine made from blueberries grown by Xue Ziliang himself in my place, the alcohol content is not high, you can drink it as a drink - it is hot enough here."

"How embarrassing is this, you always bring things to ......" Lin Hanlong felt a little embarrassed, Wu Nanhai has been sending things sporadically in recent months.

"It's okay, you're busy with work here, and you work night shifts every day, so you need to supplement your nutrition more." Wu Nanhai disagreed, "Isn't the farm just for the elders?" ”

Wu Nanhai said and swayed out, still holding the box of the saccharide meter in his hand. His fellow naturalizers followed him. As he was about to walk out of the workshop, he caught a glimpse of something. He turned his head to look, sighed, and then jumped out of the corner of the workshop.

"Old Forest !!!"

Lin Hanlong rushed out, and was meeting Wu Nanhai's eyes glowing with a faint green light, and couldn't help but say secretly: "It's broken!" ”

Wu Fatzi trembled and pointed at a row of curved cast iron workpieces with his fingers, and said in a trembling voice: "Obvious, obvious, microscope...... You, why didn't you tell me. He was pointing to a row of microscope holders, no different from those used in later generations.

Lin Hanlong smiled bitterly, "You didn't ask me if I could do it." These are set by the Ministry of Health, and they are also very urgent. ”

Wu Fatzi immediately jumped up. "I didn't ask because I thought it was a difficult thing to do! Didn't it say that it could only be mass-produced in the 19th century? "I used Leeuwenhoek's method, using surface tension to make aspheric lenses, which is quite easy to get." Lin Hanlong pretended to be bland, "Of course, with a slight improvement, it can produce products of multiple specifications with an accuracy of less than one percent." ”

Wu Nanhai stared at Lin Hanlong for a while, and laughed. "Lao Lin! Engage in optics, we will belong to you in 500 people! What others can't! ”

"That's not it, there's also-" Wu Nanhai's hand slapped heavily on Lin Hanlong's shoulder: "Old Lin! You have contributed a lot to the work of our Ministry of Agriculture! I, Wu Nanhai, understand it very well in my heart! Wu Fatzi patted his chest unkemptly, "Don't talk nonsense, in the future, the work of the optical factory will be strongly supported by our Ministry of Agriculture." Such an important matter should be given priority to development. Executive Committee, I'll take care of it! ”

The two laughed again.

Wu Nanhai suddenly remembered something. "Lao Lin, according to your habits, you must have made a few shiyan products before mass production, right?" As he said this, the green light in his eyes was enough to illuminate the entire workshop.

In addition to being a little rougher, the self-made microscope that Lin Hanlong took out looked no different from the products of later generations at a glance. He pointed to the objective and said, "Three magnifications, 50, 150, 300." However, the positioning mechanism is not too good, so you should be careful when turning, and adjust it slightly to avoid improper light paths. He pointed to the goggles again: "The goggles are not painted, wipe them clean in time after use, otherwise sweat will corrode." ”

Lin Hanlong found a piece of cloth to wrap the microscope: "If you don't make a box, you will just take it." This is a trial product, and there are many small problems, pay attention to some when you use it, and tell me if you have any problems. ”

"Well said! Say! Wu Nanhai walked out contentedly, holding the sugar meter in his left hand and the microscope in his right hand.

Sending Wu Nanhai, who looked like a devil out of the village, Lin Hanlong asked the apprentice to get a towel to wipe his face, and hurriedly started the second inspection of the workshop. The workers' professional level is not high, and even if they are proficient, they are not in a state of understanding. Half a bottle of vinegar is the most dangerous, and bad things happen from time to time, and it is impossible to prevent it.

When Lin Hanlong inspected half of the grinding machine group and was listening carefully to the sound of the machine, someone came to report that there was a chief Qian looking for him at the door.

This chief Qian has a strong figure and obvious muscle lines. A veteran in a T-shirt, shorts, and sunglasses, with a pistol holster tied to his thigh, revealing the handle of the gun with a square head and square brain. Although it is a standard outfit, if you look closely, this outfit is actually very different from others. The sunglasses are the kind of Tom in Top Gun, the T-shirt with a collar in solid color can actually be worn with a sense of trimming, the shorts are clearly military products such as 511, and even the shoes are not ordinary running shoes that can be seen on the market.

The visitor took off his sunglasses, revealing a pair of piercing eyes. It is the current speaker of the parliament and the leader of the house party, Qian Shuiting.

"Old money! What wind is blowing you here? Lin Hanlong greeted him with haha.

"I happened to go to the machinery factory today to investigate, and I will come to you to take a look when I am busy. How's it going, have you eaten? ”

Lin Hanlong shook his head. "There's no time. I'll let the cafeteria deliver something later. ”

Qian Shuiting took out a big box from the straw pocket behind him: "I have something to prepare here, why don't we eat some together?" ”

Inside the box were two large lunch boxes preserved with ice cubes, and Lin Hanlong glanced at the boxes. "Sushi! Where did you get this? ”

The rice balls in the box are rolled in seaweed and covered with red and white fish. It is the Japanese sushi that will be known to the world for generations.

Lin Hanlong invited Qian Shuiting into the office. There are too many things on the desk to clean the place, so let people set up a small folding table and wipe it down to the dinner table. The two sat opposite each other. Lin Hanlong asked his apprentice to bring a few bottles of kvass - it was inconvenient to drink wine during working hours.

Qian Shuiting said that when he was working in California, he also worked in a Japanese restaurant, so it was no problem to make sushi or something. It's a pity that there is no suitable sushi rice in the local area, and the taste can only be satisfied. Of course, there is no sushi vinegar, but the heavenly kitchen has brewed white vinegar, which is used as a substitute for the time being. The Feiyun can often go out to sea to fish, and has made an appointment with some fishermen to send good goods, so the seafood and meat are still fresh

"Heavenly Kitchen has *** soy sauce: after all, everyone often eats sashimi." Qian Shuiting said and opened a lunch box, "This is fresh mustard from Wu Nanhai - I grind it out myself, but it's not mustard paste." ”

"Speaking of Wu Nanhai, he just got out of me." Lin Hanlong, who has always adhered to the view that it is better to be happy alone than to be happy with everyone, picked up Li Quan's limited edition cigar from the table, "How about one, one later?" ”

"No, you'd better smoke it yourself." Qian Shuiting said, "I have to be strict with myself now. ”

At first, Lin Hanlong thought that Qian Shuiting meant caring for his body, but later he understood: "You mean you can't take other people's gifts?" ”

"That's what it means."

"It's just a box of cigars...... Lin Hanlong disagreed, this kind of private gift to pull feelings, almost everyone in the patriarchs has a share.

Qian Shuiting shook his head: "We don't lack these circulation coupons, it's better to buy them directly, it will be a stain to save the right scene." Lao Wu is very good, and he can't stand someone-" probably felt that this was inappropriate, so he stopped saying it.

"Do you think this is the United States......" Lin Hanlong felt that since Lao Qian organized the otaku party and became the speaker, his behavior was very different from before - he was a little too neurotic, and politics was really not done by ordinary people.

"It's not the United States, so I have to pay attention. It would be easier to do it in the United States. Qian Shuiting said and poured him a glass of kvas, "Come, have a drink first." ”

After a few sushi dishes, Qian Shuiting stared at Lin Hanlong: "Lao Lin, I didn't say you. You're a little thinner than last month. ”

"Huh? I don't think so. "Lin Hanlong has a big appetite, and the weather is hot, and eating cold food like sushi is his appetite.

Qian Shuiting picked up the chopsticks and nodded: "You black and white are upside down." I started work all night at night, and I had meetings in the morning during the day, and I had to do things in the machinery factory. Noon is the hottest time, how to sleep well? He picked up a piece of sushi and put it in Lin Hanlong's bowl, "This one is flying fish roe, very good." You eat more. I didn't sleep well, I didn't eat well, and I was tired. Can you not lose weight? Do you still want this body? ”

"In the initial stage of the career, hard work is always inevitable."

"Everyone is a start-up, and you have a lot more work than others."

"In the fall, when the optical factory has an independent power source, there will be no need to work night shifts. That's when it was easier. ”

"That's it. The steam engines of the machinery factory are sent out one by one, why do you have to wait until the autumn to have this optical factory? ”

This is poking Lin Hanlong's sore spot.

"As you know, some people in the executive committee say that it is not too late for optics to develop in the second or third five. You tell me? ”

Lin Hanlong shook his head: "What do they know." How many people urge me to ask for this and that, but I can't do it. ”

"That's right! They only understand their own one-third of an acre, who understands better than whom? It's only been a few years, and I don't listen to what the front-line veterans say. ”

"None of the members of the executive committee have engaged in scientific research, not even as a graduate student. I don't have an intuitive experience of scientific research and development. ”

"If this continues, how to climb the technology tree is up to a few of them? Isn't this a layman leading an insider? ”

Lin Hanlong waved his hand: "Forget it, eat." "He was so hungry that he quickly killed most of the box of sushi. A bottle of kvass was also drunk to the bottom.

Qian Shuiting watched Lin Hanlong put down the kvass bottle and said, "I think there has to be a voice to speak for the first-line Jishu elders." ”

Lin Hanlong looked at Qian Shuiting and did not speak.

"Take your optical factory as an example, many people think that we still have a lot of inventory, so there is no need to rush it. If you want me to see, no matter how much inventory you have, the categories are always incomplete, and the quantity is always limited. ”

Lin Hanlong nodded in agreement. "There are a lot of things that people from all walks of life ask me for, and some of them have never been heard of before."

"Lao Lin, you are so busy that you are on all fours, and black and white are reversed, and it is not easy to say something. I am the Speaker, and speaking is my job. I feel like I have to speak for the vast number of Jishu elders. Qian Shuiting looked at Lin Hanlong with a sincere face

"We understand the importance of your optics. But how far can we go at this stage, can you give me an explanation? ”

Lin Hanlong nodded again: "This will trouble you." He was silent for a moment, and then organized his words. Optics, in terms of theory and design, our time and space is a very mature thing. He pointed his finger at himself, "I came from an optical class, and my job is also an optical job." Design or something, I can do it. Process manufacturing, to say that it is not particularly difficult. Many enthusiasts can grind lenses themselves, and at least my professional class will not be worse. To put it bluntly, optical things are mainly a kind of precision machining, which is nothing more than a relatively small amount of processing, and there are relatively simple ways to make accurate measurements. He looked at Qian Shuiting and paused, "I dare to say that as long as the resources are enough, I can always reach the level before the 20th century in a few years." ”

Qian Shuiting was excited. "Lao Lin, you are so powerful here! That's great! ”

Lin Hanlong nodded. "Seeing is believing. Last time you said you wanted to see me here, are you free today? I'm on my way to the rounds. ”
