例句與用法

  • Taking gear case as research object , we studied the sound radiant efficiency of complex box - shape structure under practical stimulation by experiment , mainly observed the difference of sound radiant efficiency between the complex structure under practice stimulation and the known simple structure
    以變速箱為對象,對實際激勵條件下箱形結構的聲輻射效率進行了試驗研究,重點考察了這種結構在實際激勵下的聲輻射效率同已知的簡單結構聲輻射效率的異同以及激勵的改變對輻射效率的影響。
  • By experiment , we found that the variation of gear case radiant efficiency with frequency keep accordance with that of simple one as a whole , but the radiant efficiency of gear case will go beyond any calculation result of empirical formula when the frequency is below 250hz . we also found that stimulation changes affect radiant efficiency little by varying speed experiment , and it can be ignored in engineering calculation . the rectangle structures as gear case , possess characters of both plane and ball , and their sound radiant efficiency lie between plane and ball region
    通過試驗發現,總體上變速箱輻射效率隨頻率的變化規律同簡單構件的輻射效率是一致的,但在250hz以下的低頻區域,變速箱的輻射效率大大高于任何一個經驗公式的計算結果;通過換檔試驗發現,激勵的改變對輻射效率的影響不很顯著,工程計算可以不予考慮;對于變速箱這類三個方向尺寸差別不大的結構,其輻射性質具有平板和球源的雙重特征,輻射效率介于平板和脈動球源之間,據此提出在工程應用時可以取平板和脈動球源輻射效率的平均作為此類結構輻射效率的觀點。
