应力转变 meaning in English

transformation for stress

When the annealing temperayure was 400 , the stress of film was from tensile stress to compressive stress . when the annealing temperayure was 600 , the full - width at half - maximum ( fwhm ) was the narrowest from xrd pattern
研究发现,在空气中退火温度到400时,薄膜的应力由拉应力转变为压应力, 600时, zno薄膜的半峰款最窄。
Therefore one of efficiency means to solve cracking problem of runners is to change distribution of welding residual stress of blades , to decrease welding residual tensile stress in the dangerous area of blades or even turn to compressive stress
因此,改变叶片焊接残余应力的分布状态,降低叶片危险区域的焊接残余拉应力峰值,甚至将危险区域的拉应力转变为压应力,是解决转轮裂纹问题的有效途径之一。
