碰撞截面 [物][天] collision cross section
- 粒子间的碰撞主要考虑同位素离子和原子间的共振电荷转移,用碰撞截面来处理。
The collisions between particles mainly considered charge exchanges between isotopic ions and atoms, which were treated by using cross section. - 本文计算了电感耦合氩等离子体中各碰撞截面及电导、热导、扩散和粘滞系数。
Collision cross sections as well as electrical conductivity, thermal conductivity, diffusion coefficients and viscosity coefficients of an inductively coupled argon plasma are calculated. - 本文将条纹干涉仪与透射仪联合使用,测定了在某些温度下慢电子与中性粒子的平均碰撞截面。
Moreover, the average collision cross-section between a slow electron and a neutral particle is measured at several different temperatures using both the interferometer and the transmission methods.
