摘要
根据Ｙｏｕｎｇ－Ｌａｐｌａｃｅ方程对液态铀溶池的自由表面进行了数值计算。得到了表面凹陷与表面温度分布的关系。阐明了电子枪加热金属表面时出现的凹陷是由于原子蒸汽对液态金属表面反冲压力所引起的，而不是电子束的冲量造成的观点。对不同最高温度及不同熔池宽度的液态铀熔池表面凹陷形状进行了计算。
The free surface of liquid uranium in molten cavity has been studied by solving Young-Laplace equation. The relationship between crater and temperature distribution on the surface hasbeen obtained.It is presented that the crater on metal surface when heated by electron gun iscaused by recoil pressure of atomic vapor to liquid metal surface,but not by impulse of electronbeam. The shape of the crater has been calculated numerically on the basis of various temperaturemaximum and various width of liquid uranium molten cavity.It provides facility for numericalcaiculation inside molten cavity.
