frequency jumping 中文意思是什麼
frequency jumping
解釋
頻率躍變-
Even under the condition that the filling pressure was up to 1. 5mpa, the onset temperature was only 237 ?. with the filling nitrogen of 0. 9 mpa, the maximal pressure ratio reaches 1. 21 and the operation frequency is 25 hz. the ratio of the harmonic wave of the engine was very little and the frequency jumping was not found in present experiments
在充氣壓力為0 . 9mpa的條件下，該熱聲發動機最大壓比可達1 . 21 ，遠高於駐波型熱聲發動機，實驗結果和理論分析均表明系統的工作頻率為25hz左右，實驗裝置的諧波比例非常小，且也沒發現頻率跳變等現象。 -
