migration length meaning in Chinese

迁移长度
移动长度
徙动长度

Abstract : based on the concept of space migration length of photo - activation species , the analytical expression of the total number n of photo - activation species that can reach a segment on the substrate in the cubic deposition reaction space is derived . the simulation of the relationship of deposition rate and position of substrate is also completed . the simulation result agrees with the experiment data well
