For pc , the pulse diffusion layer only depends on the diffusion coefficient of cations and the pulse length , is not related to the concentration of the mass 單脈沖擴散層的厚度僅取決于陽離子擴散系數和脈沖導通時間,與溶液本體濃度無關。
In the case of ultrashort laser pulse , the effect of finite pulse length is anlyzed , and self - steepening in the front of the pulse will occur when only relativistic nonlinearity is considered 同時,對于超短脈沖傳輸,分析了有限脈沖寬度效應對傍軸方程的修正,當只考慮相對論性非線性效應時將會引起激光脈沖前沿自陡峭。
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 結論是:當脈沖長度接近等離子體波長時,稀薄等離子體將發(fā)生“前向受激raman散射” ,它使脈沖后沿拉長,導致尾流場的相速度變小,以至于被尾流場“捕獲”的電子最大動能大大下降。
