stress difference meaning in Chinese
应力差
Examples
- Second normal - stress difference
第二法向应力差 - First normal - stress difference
第一法向应力差 - Ei ghteen types are formed in space according to major stress difference of modern structure stress field
以现代构造应力场主应力差为主在空间上构成18种类型。 - This kind of structures will cause the principal stress difference bigger due to the sharp changes modulus of deformation between auxiliary core and main core , auxiliary core and upstream and downstream transition materials , which is disadvantage of stress transmission
该种心墙的结构型式，由于副墙与主墙、副墙与上下游侧过渡料的变形模量发生突变，不利于应力的传递，造成主应力差值偏大。 - When the substrate is fr4 , the surface shear stress and normal stress difference is at a low level and near zero during curing process and build up during cooling down because of the mismatch of ctes of silicon and substrate
对于fr4基板，在固化过程中，芯片表面的剪切应力和正应力的值很小，其数值在原点上下很窄的范围内波动。在降温过程中，热膨胀系数的失配随着温度的降低而越来越显著，引起应力的积聚。
