气体分子的性能好像和完全弹性的物体一样。

The establishment and relaxation processes of the transient gratings, which are formed by two recording 514nm beams with different polarization directions, SS, PP, SP and ±45℃, are investigated. Using the weak absorption of the chromophores at 632. 8nm and the positive dichroism of the chromophores molecules, a kind of bi-photonic transient gratings, owing to the periodic distribution of Trans and Cis isomers, is established first time in azo-dye doped polymeric bulk sample.

实验考察了两束514nm的写入光在不同偏振情况下（SS，PP，SP和±45），在样品中形成的瞬态栅的建立和弛豫情况；利用偶氮生色团在632.8nm波段的微弱吸收和生色团分子的正二向色性，首次在块状偶氮聚合物材料中形成一种基于生色团反式和顺式异构体密度分布的双色光瞬态栅；利用瞬态栅的快速建立和弛豫，考察了其在衍射型全光开关方面的潜在应用。

Therefore,it is importance task that we should not only knockout α-1,3GT and relative molecules from pigs,but also ensure safety in public health of XP from PERV.

因此，即要剔除导致人类排异反应的猪细胞表面的α-1，3GT及其相关的分子，又要确保猪器官异种移植的安全性，是尚待研究的重大课题。

The process whereby heavy molecules of naphtha or petroleum are broken down into hydrocarbons of lower molecular weight (especially in the oil-refining process).
