So it's necessary to design the briachial-bridge luffing mechanism and curve slideway live control weight gravity balance system in a new way.

而对于变幅系统和曲线滑道活对重自重平衡系统的设计，传统意义上单纯的通过建立数学模型进行优化的方式来进行设计，或者单纯的作图法来设计，在很多方面暴露出弊端，如优化得到的点离实际需要的太远，或者作图设计速度较慢等，正因为如此，有必要对变幅系统和曲线滑道活对重自重平衡系统的设计重新做出一种新的尝试。

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。"
