However, there are also some early products that are still dead and have not retired, but the reason is not difficult to guess, "although these products have been backward, but some are cheap, and some are still useful under some special requirements, it seems that they must be completely replaced, completely lose their use value before disappearing, such as the KClO3 explosive that is likely to have disappeared just after the invention." ”

After realizing this, Li Hui's heart suddenly moved, "Wait, if that's the case, wouldn't it mean that sodium chlorate petrolatum explosives can completely replace KClO3 explosives?" Doesn't hygroscopicity have any effect at all? ”

The answer to this question is not difficult to find, Li Hui just thought about it, and the detailed information about sodium chlorate petrolatum explosives was displayed in front of his eyes, and sure enough, as he thought, the validity period of sodium chlorate petrolatum explosives was quite long, so long that he couldn't believe it.

So naturally, an idea came to Li Hui's heart, "Could it be that the sodium chlorate produced by the system is extremely pure?" It's not that it's not impossible, the silver proposed from the system is all thousand-foot silver, and the impurity content is less than one thousandth."

"Anyway, there is still some leftover sodium chlorate that I bought before, and I can't sleep now, so let's just do a comparative experiment to verify it." Thinking of this, Li Hui, who was not sleepy, immediately got up and put on his coat and hurried back to the laboratory

It doesn't take many days for the purchased sodium chlorate to be completely deliquescent, and the system production (as long as the system can produce a certain finished product, then the corresponding parts and raw materials can also be produced. The sodium chlorate crystals did not show the slightest sign of moisture, and the conclusion was obvious. Later, Li Hui measured the purity of sodium chlorate produced by the system through experiments, and it was indeed above 99.9%, which made him further realize the huge advantages of the system products. In fact, all system products are one in a thousand excellent products, and the price is very cheap, but unfortunately the system for the consumption of precious metals is irreversible, and the hidden cost is actually very high.

But at least there is no need to worry about the problem of sodium chlorate being easy to deliquescent for the time being, and the new formula of silver explosives has immediately entered the actual testing stage. This time, everyone had prepared their sunglasses beforehand, and although the flash of light from the explosion was stronger than the last time, no one was dazzled again, and the flaws of the silver explosives were finally exposed

"It may be that there is too much aluminum powder, the detonation rate has dropped so much, there are not a few shrapnel blown up at all, and the flight distance is not far enough, and people who don't know still think that it was made in the border area." , Li Hui couldn't help but shake his head again and again after approaching the explosion site, but after seeing the iron plate as a target, he still decided to continue to use this formula, "At least the destructive power against hard targets is really strong, and it is still very useful to use it to hit warships, as for the task of killing people, anyway, there are cheap white explosives (sodium chlorate petroleum jelly explosives)." ”

The generals of the Beiyang Navy Division were full of praise for the incredible explosion power of the new version of the silver explosives and the ultra-high temperature deflagration special effect produced during the explosion. Among them, Ye Zugui, who has always been careful, also noticed that the damage of the two control targets was almost world-apart after being shot, and said in surprise, "This destructive power should be far more than four or five times that of the black medicine, you look at the big hole blown out of the iron plate on the right, which is dozens of times larger than the shell with black medicine on the left?" Isn't there a simple linear relationship between the power of a single shot and its destructive power? ”

In fact, "under the premise that the ammunition transmittance is comparable, a single more powerful artillery shell can cause greater damage to hard targets (such as warships, tanks, fortifications, etc.)." This conclusion is known to many people in later generations, but because the difference in the charge of the same caliber and type of shells is generally limited, and the caliber of the artillery equipped with the same grade weapon platform is generally unlikely to have a big gap, so this problem has no value for in-depth research, so Li Hui only knows that the power of a single shot can take advantage of it, but he does not know how big the price is. Originally, because of the influence of the mindset, Li Hui didn't think about studying this issue, but now Ye Zugui's words made him think differently

"Generally speaking, warships of the same grade are equipped with the same grade of artillery, and the shells of the two sides are rarely very different, so the specific impact of the power of a single shot is not worth in-depth study. However, the situation of the First Sino-Japanese Naval Battle is more special, the devil has rapid-fire guns, we don't have them, but the ultimate caliber of the rack and back guns that can be equipped with warships of the same tonnage is much greater than that of rapid-fire guns (because the recoil force transmitted to the hull when the rapid-fire guns are fired is much greater than that of the same caliber frame guns, take the Zhiyuan as an example, if the double-mounted 210mm front main gun is replaced with a rapid-fire gun, the 150mm caliber can only be single-mounted. Therefore, under the premise of the same type of shells, we will have a clear advantage in the power of a single shot, coupled with the silver explosives, which even surpasses the explosive power of picric acid explosives, in the Sino-Japanese naval battle of this time and space, the single shot power of the shells used by the Beiyang Navy Division should have an overwhelming advantage. In this case, it is necessary to understand the effect of the power of a single shot. This is because only by understanding this issue can we understand how big the gap is in the firepower of the main fleets of China and Japan, and can we formulate correct strategies and tactics. Moreover, I have an incomparable advantage in researching this topic, if I do experiments in reality, I will have to shoot at least tens of thousands of shells and dozens of target ships, which is too costly; However, there is a column of 'survivability' in the data of various ships in the system, which is expressed by the number of hits required to disable the ship without hitting the critical part of a specific type of shell, and I can freely choose the model of the shell, I only need to write down each data set for comparison, I don't believe that I can't find the law", Li Hui thought about it, immediately stopped his afternoon nap, turned over, took out a pen and paper and began to record

"The two extremes must be ruled out, otherwise there will be no law at all. The first example is that 3 kg of charge requires 67 rounds, 6 kg of 6 kg of 23 rounds, 10 kg of 11 rounds, and 18 kg of 5 rounds; In the second example, 5 kg requires 53 rounds, 10 kg needs 19 rounds, 20 kg needs 7 rounds, and 40 kg needs 3 rounds", at this time, Li Hui couldn't help but thank the strict requirements of the chemistry teacher at the university, if it weren't for this, he would not have been able to summarize the empirical formula that could be used based on these rough data alone.
