Sui Chengzhi didn't care about anything at this moment, didn't say a word, just watched from the sidelines, and looked at each other coldly. After looking at the new goods cutting and sewing pants for a while, I also felt bored in my heart, and I had nothing to do, looking around, looking at all the things in the clothing store, and looking for some new things that I usually don't see much. At this glance, he looked back and saw a set of three sets of timing leaky pots that he had seen before behind him, and he didn't attract much attention when he was free, and when he had spare time, he calmed down and concentrated on looking.

I saw that this set of timing leaky kettles is made of bronze, and there are four leaky kettles superimposed and combined, respectively on the stepped copper frame, one step at a time, three feet apart, along the stepped copper frame, step by step. In the four leaky kettles, the upper three leaking kettles are all cylindrical, there are three legs below, two and a half feet high, for the sowing kettle, the body of the kettle is close to the bottom of the kettle and there are small holes on the side, the drip pipe is installed, the outside passes out, the flowing water all flows out and drips from the two small holes, and finally drops into the receiving kettle of the lowest layer, the flow of water is smooth and symmetrical, almost equal. The bottom of a leaky kettle is also cylindrical, there are three legs under it, the height is higher than the top three leaking kettles, up to three feet, for the kettle, the body of the kettle is close to the bottom of the kettle without holes on the side, there is no drip pipe installed, so that the water drips into the leaky pot has been hoarded in it, more and more, can not pass out, leak out, this kettle is specially used to observe the increase in the inflow of water in the container, in order to measure the hour, therefore, it is equipped with a standing arrow, that is, a standard rod, straight into the inside, the jargon is called an arrow, in fact, it is a rod, there is an arrow boat under the arrow, the top is supported to make the arrow float on the water, do not make it sink down, the head of the vertical arrow is divided into scales, a total of 100 minutesAfter the kettle is impounded, it keeps rising, revealing the scale on the head of the arrow, and the scale is represented by the scale parallel to the water level, which is considered to be timekeeping.

He only read a lot of historical books. I know a lot about the knowledge of the timer leaky pot, and I know a lot about it, and I think about it carefully according to the detailed records of many historical books. I know that the world has always been unified in the name of the timing leaky pot, and it is called the timing leaky pot according to the number of the above sowing kettle, and the bottom one is only separated separately, not called in the timing leaky pot, therefore. Obviously, four leaky kettles are superimposed on the same stepped copper frame, but they are called a set of three timer leaky pots, not a set of four timer leaky pots.

After carefully looking at this expensive and extremely advanced water-receiving bronze timing leaky pot, I was amazed and envious. Thinking that this set of timing leaky pots is rarely seen, it can be called rare, and it is a new product, and I am surprised.

Between the heartbeats, I recalled in my mind that the leaky pot was a common instrument used by the ancients for timekeeping. Most of them are made of copper, the earliest appearance of the age is unknown, once called the carved leakage, known leaky pot, the Zhou Dynasty has been molded leaky pot use, called the pot, the Spring and Autumn Period, greatly popularized, but all the people in the world, as long as it is a person. Living in the world, whether it is the emperor and the princes, or the common people, almost all rooms are used. It can be said that every family has it, it is used very widely, and it is seen a lot.

It is also known that after many years of use, the leaky pot is no longer a single form of leaky pot, but is divided into two forms of leaky pots, namely the leaky pot and the water-receiving leaky pot.

These two forms are leaky pots. Although the timing method is slightly different, in terms of shape and shape, it is roughly the same, which can be described as: "The same is the same, ** is not far from ten." ”

The specific characteristics are: the leaking kettle body outside are cylindrical, there are three legs below, the upper sowing kettle is two and a half feet high, the bottom one is three feet high, the difference is that the sowing kettle body has small holes on the side near the bottom of the kettle, the small holes are installed with drip pipes, can be drained out, the lid of the leaky pot has a square handle, and there is a rectangular hole in the center of the handle, which is used to support the standing arrow, so that it can be interspersed in the leaky pot normally, standing upright, as the ruler of the hour, wherein, all the small hole size on the leaky pot is all the same and consistent, exactly the same, and the vertical arrow in the leaky pot is usedThe water level in the leaky pot gradually decreases, and the scale on the scale is gradually revealed. The body of the kettle is not porous on the side near the bottom of the kettle, and there is no drip pipe installed above and below the kettle, but it is specially used to hoard the water flow, so that the water level cannot help but rise, and it is used to keep time.

This is the difference between the outside of the leaky kettle, as for the inside, it is the same, that is, it is inserted into a rod, called an arrow, there is an arrow boat under the arrow, which is supported to make the arrow float on the water surface, so that it does not sink down, and the head of the arrow is divided into scales, which is calculated in total, for a hundred ticks, and the water flows into the leaky pot, or sinks, or rises, and the water level is parallel to the scale, that is, the hour, which can be calculated.

In addition, the drain type leaky pot, the water flow into the leaky pot, the arrow will sink, called the sinking arrow leakage; the water type leaky pot, the water flow into the leaky pot, the arrow will rise, called the floating arrow leak, these two types of leaky pot can be used to indicate the time, know the time, therefore, there is a common name, that is, collectively called the arrow leak.

Only because the height of the single pot draining type sinking arrow leakage pot is too low, the capacity is small, the water flow is hoarded inside, from the full to the excretion is finished, before and after, it is less than an hour, or half an hour, and even more so, even less than half an hour, the water flow in the leaky pot is discharged from full to shallow, the flow rate before and after is just different, very uneven, with the reduction of the water flow in the pot, the flow rate is also slowing down, the stability and accuracy of the timing are greatly affected, and there is a big deviation, therefore, the accuracy of its calculation of the hour is really not high, and it is used by astronomers to watch the starsAfter a thousand years, after a long period of use, the single-pot draining type sinking arrow leak has almost disappeared and is no longer used.

For thousands of years, the people of the world have many capable people and extremely intelligent people, after several innovations, many attempts, and finally succeeded in research, thinking of a method.

It is to put two or three leaking kettles, that is, sowing kettles, superimposed together, placed on the same vertical steps or copper frames, up and down, lined up in a line, the water is discharged from above, and the leaky kettle is caught below, and between each other, do not stop supplementing, so that the circulation is carried out in stages, and the stability of the flowing water in the leaky pot below is greatly improved, and finally flows into a leaky pot placed at the bottom, that is, in the kettle, completely hoarded, so that the water level in the leaky kettle does not rise, and the standing arrow with the calculation of the hour scale in the kettle does not help to rise, so as to calculate the hour, the stability and accuracy are improved a lot。 (To be continued.)
