当地层中水和温度的量值变化时,地层便膨胀或收缩,依附于地层的形变测量标志也就随之而被移动。
When the content of water and temperature in the layers changes, the layers expand and contract and the measure mark of deformation is also moved.
延长定型时间有利于高弹形变的松弛,降低内应力,有利于降低干热收缩。
Prolonging the heat-setting time to provide enough relaxation time for high elastic strain, which can also reduce the inner stress and the dry heat-shrinkage.
随着激光单脉冲能量输入的增加,焊接件的横向收缩变形和失稳变形变大。
With the single-pulse laser energy input increasing, the transverse shrinkage and buckling distortion are improved.
