initial rate

The pipeline steel with strain-based design is usually characterized by high initial work hardening rate, good ductility, and low yield stress to tensile strength ratio.

抗大变形管线钢就是基于应变设计的方法得到的具有连续屈服、较低的屈强比、较高的加工硬化指数以及均匀塑性变形延伸率等特性的管线钢。

The tensile impact experimental results show that the initial elastic modulus and unstable strain of PE fibre bundles are temperature and strain-rate dependent, except for the failure stress of PE fibre bundles.

实验结果表明：PE纤维束的初始弹性模量和失稳应变具有一定的温度和应变率相关性，但是破坏应力变化不大。

This initial rate increment may be due to the development of the internal oxidation layer.

这初始速率增加的原因可能是发展的内氧化层.

The structure of amyl alcohol affects both the initial reaction rate and the ultimate yield of amyl n caprylate in the following sequence: primary alcohol> secondary alcohol> tertiary alcohol.

醇结构对MIECC有影响，在反应初速率及平衡产率方面均遵循伯醇>仲醇>叔醇的规律。
