Loss index of a dielectri
電介質的耗損指數Based on the nonlinear paraxial equation and b - t theory, a differential equation, which describes the small - scale self - focusing in gain ( loss ) media has been derived. the change rule of the maximal gain frequency, cutoff frequency and integral exponential gain have been analyzed approximately
我們首先從非線性近軸波方程出發，基於b - t理論的思想，在考慮了介質的增益（損耗）特性的情況下，推導得出了小尺度自聚焦所滿足的微分方程，並通過近似方法分析了最大增長頻率、截止空間頻率及積分指數增益等的變化規律。The paper introduces electric power insulation material ’ s dielectric loss mechanism under the action of electric field, points out the major factors which influence insulating oil dielectric loss and important significance of measuring dielectric loss
論文介紹了電力絕緣材料在電場作用下產生介質損耗的機理，指出影響絕緣油介質損耗因數的主要因素和測量絕緣油介質損耗的意義。This paper proposes a two - armed push - pull inverter, including its topologies, power distributions in every switching devices and modulation schemes. the major parameters such as thd and df of this vsi are analyzed. comparison study shows that the quality of two - armed push - pull vsi is better than those of square - wave vsi. and the switching loss is lower than that of pwm scheme at same time, especially used in wide frequency range. detailed calculating formulae and experimental results are presented
該文介紹了一種雙臂推挽式逆變器，包括其電路拓撲、每個開關器件的功率分佈和調制策略.分析了這種電壓源逆變器的主要參數，如總諧波失真度（ thd ）和失真指數（ df ） .比較研究表明，這種逆變器的質量明顯優于方波逆變器，同時開關損耗明顯低於pwm調制方式，特別適用於寬頻范圍.介紹了計算公式和實驗結果分享友人
