The initial portion of the stress-strain diagram for most materials used in engineering structures is a straight line.

在工程结构中使用的大部分材料最初的应力应变图是直线型的。

To the deep rock engineering, stress state of rock mass directly influences the stability of project.

对于深埋岩石工程，岩体的地应力状态直接关系到工程的稳定性。

One of the basis for plant genetic engineering is study on the function of stress-related gene.

研究抗逆相关基因的抗逆功能是基因工程抗性育种的前提。
