1·A good example of this is found in the kinetic molecular theory, in which gases are pictured as being made up of many small particles that are in constant motion.
分子运动理论便是我们能找到的一个很好的例子。在这个理论中，气体被描绘成由许多不断运动的小颗粒组成。
2·you might start with asking questions: What are the facts that underlie the molecular kinetic theory of matter?
你可以用下面的问题提问：分子动力学理论问题基于什么样的事实？
3·Analysing in the view of molecular kinetic theory, paste flowability is a shift of molecular mass center by the jump of polymer chain segment, and it affects the mass-transfer directly.
从分子运动角度分析，糊料流动是高聚物大分子链段协同“跳跃”而实现整个分子质量中心位移，对传质具有直接影响。
