weight break

This paper studied the basic properties of metallocene linear low density polyethylene ( mLLDPE), including density, melt flow rate, molecular weight distribution, melt point, yield strength, tensile strength at break, elongation at break and Izod impact strength.

研究了茂金属线型低密度聚乙烯（mLLDPE）的基础性能，包括密度、熔体流动指数、熔流比、分子量及其分布、熔点、屈服强度、断裂强度、伸长率、冲击强度等。

The idea is to break up the ice with the heavy weight of the tanks.

这样做的目的是要用坦克的重量来破冰.

Some performance indexes such as surface contact angle, molecular weight, crosslinkage, tensile strength and break elongation etc. were investigated.

In optimization design of the slide-valve pump, we break through the usual method of adding outer clump weight or balance wheel, and adopt the method of changing the inner structure and add inner clump weight to optimize the pump's vibration balance.

在优化设计中，我们突破以往采用的外加配重块或平衡轮来平衡惯性力的方法，通过改变滑阀真空泵内部结构及添加内平衡块的方法对滑阀真空泵进行振动平衡优化。
