pulsed laser beam中文什么意思
例句與用法
- The main results are as follows : 1 . the propagation of an ultrashort intense pulse laser beam in low - density plasmas is investigated analytically . relativitistic pondermotive force and space - charge effects are included , and an equation describing the evolution of the laser spot size is derived
考慮有質(zhì)動力與電荷分離場的平衡，推出了超短超強脈沖激光在低密度等離子體中的折射率、電子密度和電荷分離場的表達式以及激光束斑的演化方程。 - Ultrashort intense laser pulse propagation in low - density plasmas and air xiao yuan , doctor of philosophy , 2002 dissertation advised by : lu baida , professor of physics the study of ultrashort intense pulse laser beams in low - density plasmas and air is relevant to a wide range modern application
超短超強脈沖激光在低密度等離子體和空氣中的非線性傳輸是當今強激光與物質(zhì)相互作用研究的一個重要課題。本論文闡述了超短超強激光在低密度等離子體和空氣中的長距離自聚焦和自導引效應。 - When passed through the beam - splitter , a pulsed laser beam was split into 3 beams with an interpulse delay of 13 ns . these 3 separated laser pulses reach the m - z interferometer at different time and each laser pulse gave a snapshot of the implosion state . thus three different - time interferograms can be obtained in one shot of z - pinch
激光器發(fā)出的光束經(jīng)過分光系統(tǒng)被分成時間間隔13ns的三束光，它們于不同的時刻先后到達m - z干涉儀，每一束激光脈沖可以記錄下等離子的一個狀態(tài)，從而可以得到三幅不同時刻的干涉圖。 - In the master thesis , the fatigue characteristics of the ferroelectric films under thermal load and electrical load were investigated . the thermal load was induced by a pulse laser beam of nd : yag and the electrical load was made by rt6000s ferroelectric tester t o act on the films respectively . the effect of thermal or electric loads on the films properties was discussed
本文對鐵電薄膜在循環(huán)的熱載荷和電載荷作用下的疲勞特性進行了研究，分別用nd ： yag脈沖激光器模擬熱載荷、用rt6000s鐵電測試儀模擬電載荷作用于鐵電薄膜，根據(jù)實驗結(jié)果探討了這兩種載荷對鐵電薄膜性能的影響。
