wake wave meaning in Chinese

尾哩

We found the " forward stimulated raman scattering " will be excited if the pulse length is greater than plasma wave length . the " forward stimulation raman scattering " decreases the phase velocity and the amplitude of the wake wave which will lead to the reduction of maximum kinetic energy of the electrons trapped
结论是：当脉冲长度接近等离子体波长时，稀薄等离子体将发生“前向受激raman散射” ，它使脉冲后沿拉长，导致尾流场的相速度变小，以至于被尾流场“捕获”的电子最大动能大大下降。
Secondly , we compared the similarities and differences of two multiple pulse schemes , namely " optimum pulse spacing " and " fixed pulse spacing " . it showed that the arrangement with both the spacing between pulses and the length of the single pulse increasing as the plasma wave becomes more nonlinear will drive wake wave effectively
接着我们比较“优化脉冲间隔”和“固定脉冲间隔”两种多脉冲尾流加速方案，得到：更合理的脉冲安排应该为：脉冲间隔不断增大，脉冲长度也不断增大。
