多普勒效应体现了无线信道的时变特性。
Doppler effect reflects the time-varying characteristics of wireless channel.
体现此效应的关键在于推出时变的尾迹弯曲参数KR。
The key to represent this effect is a time-accurate wake curvature parameter KR.
当激光器上升沿变陡时，在有效作用时间内温度上升得更快，对加工区域周围热效应的影响明显减弱，而热扩散距离变小。
When the rise time is steeper, the temperature rises faster, and the surrounding of the machining filed are less affected while the distance of the thermal diffusion reduces.
考察热效应和非牛顿流体特性对计算结果的影响，结果表明对此类时变问题，热效应比非牛顿效应更显著。
Influences of thermal effects and non-Newtonian properties were discussed. The results show that for the present transient EHL problem, the thermal effect is more evident than non - Newtonian effect.
