Li Jie see Xie male and kittens here become respectfully, did not dare to say anything to disturb whites, so Li Jie did not dare say anything, only stood dry waiting for such a station is two hours, finally etc. This white finishing the experiment, the wolf stomach gave sewn on. Originally Li Jie think you can know about it and the whites, but the whites did not expect a confining itself went to heap on a bed next to the instrument, and then lie down and sleep, less than a minute, snoring ring up. Li Jie look strange look to Xie male and kittens, do not understand how to ignore this weird white Nike Free Run 2? This ......, Li Jie, sorry, Dr. Xu engrossed in the study, also some strange temper, you may not know, he generally twenty hours a day to do all kinds of research, slept only four hours a day, sometimes for several days without sleep, look like this is certainly a busy day yesterday, you see the wolf, or Nike Free Run 7.0 hit yesterday.
Anything interesting? Although Li Jie said Dr. Xu Some half understand it or not, but after listening to the Dr. Xu developed some of what he is now increasingly interested in the reasons of the disaster, and disaster after birth, all the things anomaly , want to know the reason for which in the end is what, after all, human beings are a very strong curiosity animals. Hey, this is the first in no hurry to say, Nike Free Run 3.0 to tell Nike Free Run 7.0, why same is gunpowder, but a gun can not biochemical reactions, and another on the outside but the biochemical reaction? Dr. Hui Li Jie eager to know he was ready to accept without hurry their research results to speak out, but a look of relaxed asked to Li Jie. Li Jie said with a resigned look, previously learned chemistry, but learned that what he had been thrown into the dustbin, and now he can know what is good even if a chemical reaction, Where can answer Dr. Xu problem?
Dr.Nike Free Run 5.0, Hui to watching Li Jie still do not know anything, gas impatient, said. Li Jie hear Dr. Xu's words, his mind suddenly a flash, a term previously learned as lightning flashed in my mind and blurted catalyst induced chemical reaction raw change, make chemical reactions faster or slow down or in a low temperature environment for chemical reactions. Also known as catalysts in industrial catalyst. Since Dr. Xu mentioned catalyst, that is, in guns just experiment, gunpowder reason why there is no explosion, is likely to be because of the intervention of a catalyst, leading to this should be chemically unstable encounter fire or shock students explosion of gunpowder, turned into a very stable chemical properties of substances, lost the characteristics of the explosion. But this is not right, ah, if the reason for that is because the catalyst, but this catalyst where?
