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 pool was calculated by Young-Laplace equation. The relationship between surface depression and surface temperature distribution was obtained. It is clarified that the depression that occurs when the electron gun heats the metal surface is caused by the recoil pressure of the atomized vapor on the surface of the liquid metal instead of the impulse of the electron beam. The surface sag shape of liquid uranium pool with different maximum temperature and different weld pool width was calculated.
