positive damping 中文意思是什麼

positive damping 解釋
正阻尼
  • positive : adj 1 確實的,明確的;確定的;無條件的 (opp qualified implied inferential); 絕對的,無疑問的,...
  • damping : n. 【物理學】阻尼,減幅,衰減。 damping resistance 阻尼電阻。
  1. According to these theories we know the reason of the emergence of low frequency oscillation is lacking positive damping even appearing negative damping. this problem can be classified as dynamic stability

    從而得出,電力系統低頻振蕩是由於系統正阻尼不足甚至產生負阻尼而引起的,可以將其歸類為動態穩定問題。
  2. On the contrary, because of the effect of positive damping provided by the inverter, the unit near a inveter will have no subsynchronous oscillation risk. based on the same method described above, a damping study is carried out for a hybrid ac / dc system, which include a hvdc link and an ac transmission line in parallel

    研究表明,系統整流站附近的同步發電機組要承受電氣負阻尼作用,因此有可能引起機組低頻扭轉振蕩模式失穩;而hvdc的逆變站向其臨近同步發電機組提供正阻尼,因而機組不存在次同步振蕩危險。
  3. In the dissertation, the effects of bias voltage polarity on the measurement and the normal operation are deeply researched when the voltage polarity is positive - positive, negative - positive and negative - negative respectively. the results are compared with the ones studied by others when the voltage polarity is positive - negative. the air damping of the laterally driven microstructures is slide - film air damping

    本文通過改變偏置電壓極性分別為正?正、負?正、負?負,並和偏置電壓極性為正?負配置時進行對比,深入研究了電容式傳感器在不同偏置電壓極性下,驅動信號產生的靜電力對傳感器檢測和工作性能的影響。
