A method to eliminate self - oscillation in testing hfe of low power uhf audion 時(shí)自激振蕩的一種消除方法
Self - oscillation can be generated under suitable configuration and waterpower parameters 在合適的結(jié)構(gòu)參數(shù)和水力參數(shù),就可以產(chǎn)生自激振蕩。
Research of self - oscillation characteristics of large hydroelectric machines based on finite element method 基于有限單元法的大型水輪發(fā)電機(jī)組自振特性研究
By looking for the cause of " self - oscillation , " the paper provides basis for improving the working reliability of the adjustable optical - intensity system 通過探尋自振現(xiàn)象?生的原因, ?提高調(diào)光系統(tǒng)工作的可靠性提供了依據(jù)。
There are various kinds of the self - oscillations in the preamplifier system of the high power laser facility , the origins of them were analyzed in theory 摘要分析了高功率激光裝置預(yù)放大系統(tǒng)內(nèi)外各種自激振蕩的來源,通過理論計(jì)算和實(shí)驗(yàn)驗(yàn)證提出了各種自激振蕩的抑制方法,并在實(shí)踐中得到驗(yàn)證。
