Wind cooling accelerated elimination of heat dissipation, and controlled temperature which made welding transversecontraction deformation and the residual stresses decrease.
气冷的方法，可以使试样散热更快，达到控制温度的目的，同时也可以减小焊接残余应力和焊接横向收缩变形。
2
Transverse/cross/lateral contraction deformation:The component contracts in the upright direction of weld after weiding.
横向收缩变形：构件焊后在垂直焊缝方向上发生的收缩。
3
Methods: the transverse and longitudinal contraction role of smooth colon muscle strips at the different dosage of TGP and other medicine was separately observed.
