The change from arc shape to crescent shape at the bottom of cross section of dissimilar metal K418 and 42CrMo is observed with the proportion of laser irradiation on K418 to 42CrMo altered from 1/3 to 2/3, which is due to difference of theirs physical and chemical properties.
由于K418和42CrMo热物性参数的差异,K418与42CrMo异种金属激光焊接随激光覆盖K418侧的光斑面积比例从1/3增加到2/3,大钉头小钉身的焊缝横截面尾部从圆弧形逐步过渡到月牙形。

对孤立新月形沙丘迎风坡风速的野外实测和计算表明,沙丘迎风坡表面风速廓线呈非对数关系,近地面剪切风速和输沙强度由坡脚至丘顶总体呈递增趋势,但同时随断面坡度的增减而发生相应的变化;沿断面输沙率的变化导致蚀积强度的改变,表现为沙丘迎风坡坡度变缓的部位沉积大于侵蚀,其它部位侵蚀大于沉积,其中丘顶输沙率和侵蚀强度最大。
