proportional limit meaning in Chinese

比例极限
比例限差
比例限界

For metals that experience the gradual elastic - plastic transition , the point of yielding is determined as the initial departure from linearity of the stress - strain curve and this is sometimes called the proportional limit
对于金属逐步的弹塑性形变转变，其屈服点确定为应力应变曲线非线性关系的开始，这个点也被称为比例极限。
In this dissertation , the fact that the concepts of tangent modulus factor ( _ ( 1 ) , ) , proportional limit law ( pll ) and strength utilization ratio function ( surf ) in the combined theory of strength and stability ( ctss ) are the extension of concerned concepts in elastic mechanics is illustrated
本文说明了强度稳定综合理论中的切线模量因子、比例极限定律和强度利用率函数等概念是弹性力学有关概念的延伸，既可以用于强度理论，也可以用于稳定理论。
