1. Pulse length modulation plm
   脈沖長度調(diào)制
2. Pulse length modulation
   脈沖持續(xù)時間燈
3. 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(shù)和脈沖導通時間,與溶液本體濃度無關(guān)。
4. 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(yīng)對傍軸方程的修正，當只考慮相對論性非線性效應(yīng)時將會引起激光脈沖前沿自陡峭。
5. 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
