In order to find the regularity and mechanism of vibration of CSP mill during rolling thin container strip,torsional vibration of main drive,vertical vibration of stand and suppression measures of three intermediate stands were tested in spot.Then the relationship between strip chatter marks and technological parameters,and vibration of rolling mill,and necessary conditions for chatter mark generation were researched.

广州珠江钢铁有限责任公司引进的6机架CSP热连轧生产线，在轧制薄规格钢板时出现了严重的振动问题，此时带钢和轧辊表面出现明暗相间的振纹，它加快了轧辊的磨损，影响了带钢的质量，增加了后边机架矫正表面的工作量。

I use an example quoted by Hu Jiaqi:"It is reported that America separates the DNA of a kind of virus by making use of genetic technology and combines it with another kind of DNA. Finally, they get a kind of virulent biological agent called a "pyrotoxin". Someone discloses in private that 20 grams of such a kind of biological agent could result in the global death of 6 billion people due to infection."

我在这里例举胡家奇所引用过的例子："据报道，美国利用转基因技术，将一种病毒的DNA分离出来，与另外一种DNA进行结合，拼结成一种剧毒的"热毒素"生物战剂，且私下有人透露，这种生物战剂只需20克，就可以导致全球60亿人全部感染死亡。"
