指数梯度
Examples
- Chapter 2 : the beam propagation of x - ray in an inhomogeneous plasma with a continuous varied refractive index is studied . we emphasize , theoretically and numerically , on the analysis of the effect of refractive index gradient on the beam parameters
第二章：研究了x射线激光光束在折射率连续变化的非均匀等离子体介质中的传播，从理论和数值模拟上着重讨论了折射率梯度效应对光束参数的影响。
