官能化植物油的交联固化及其缓/控释材料的研究

Today we cross the continent in fast airplanes in contradistinction to the slow covered wagons of our ancestors.

今天我们乘高速飞机横越北美大陆，与我们祖先驾低速四轮马车不可同日而语。

However, it is vulnerable to be influenced by other gas components via cross-sensitivity. Besides, it has other disadvantages including relatively slow response, low reusable rate, short life span and difficulty to achieve simultaneously monitoring.

传统的非光学式气体检测仪虽然可以达到较低的检测限，但是很容易受其它气体成分的交叉灵敏，而且其响应速度较慢，可重复利用率低，使用寿命较短，难以实时连续监测。

Then, nearly unconscious fromblood loss, he was forced to drag a cumbersome cross up a hill, was nailed to it, and was left to die the slow, excruciating torture of death by crucifixion.

当他濒临失血过多，几乎失去知觉时，还被迫拖著那笨重的十架上山，被钉，忍受死亡的煎熬，然后慢慢被凌虐而死。
