在预估中等能量沉积产生材料的动态响应时必须适当地考虑熔化过程。
Melting process must be adequately taken into accounted for the material dynamic response calculation in the intermediate energy deposition range.
它们的质量非常接近零，因此，即使在中等能量下，我们也希望它们以光速传播。
They are very nearly massless and thus, even at moderate energies, we'd expect them to travel essentially at the speed of light.
在中等能量下正电子与碱金属碰撞的弹性截面，总截面已经有理论工作计算出来了。
On the theoretical side, a number of calculations of cross sections, elastic as well as total, for positron-alkali-metal atom systems at intermediate energies have been carried out.
