light weight distribution

The apparent molecular weight of the particles and their sizes and distribution were characterized by using static laser light scattering (SLLS) and dynamic laser light scattering (DLLS).

运用静态激光光散射和动态激光光散射对粒子的表观分子量及其粒径大小与分布进行了表征。

Because joined light molecular weight gas in Elctrothermal Chemical Gun, the pressure distribution in projectile base is improved and the projectile velocity enhanced.

由于该炮在电热化学炮的基础上加入轻质气体这一理想工质，因而能大大改善弹丸后部的压力分布，提高火炮弹丸的初速。

Large-span tension structure are extensively used in China now, because of stress fit distribution, large stiffness, light weight, easily making and installing, such as truss (beam) string structure.

大跨度张力结构，由于受力合理、刚度大、重量轻、制作安装方便，目前在我国得到了广泛的应用，例如张弦桁架(梁)结构。
