equivalent difference meaning in Chinese

当量差

According to different transverse difference in temperature and lengthways difference in temperature , the paper gave the method of computing temperature effect including : 1 ) the stress ot1 caused by nonlinear difference in temperature . 2 ) the constrain stress o t2 in undetermined structures by equivalent difference in temperature . 3 ) the constrain stress ot3 caused in undetermined structures by even difference in temperature tm
针对具有不同性质的横向温差和纵向温差，本文分别提出了预应力结构的温度效应的计算方法，包括： 1 )非线性温差引起的自约束应力_ ( t1 ) ； 2 )等效线性温差引起的超静定结构的约束太原理工大学硕士学位论文应力民3 ）均匀温差tw引起超静定结构中的约束应力4 4 ）均匀温差tm引起梁的轴向变形受到柱的侧向约束，与预应力筋的温度变形之间的差异引起的预应力的变化。
