  1. This method has three merits : first, reduce the harm to the battery ; second, this current is stable ; the last, the current may represent the battery ' s current function better. in order to study this problem, we design a install to make lots of experiments to prove this result. the install can use in the factory as a automation instrument if it be perfected

    此方法和原有方法比較有三大憂點:一是減少了直接短路時大電流放電對電池的損傷:二是此迴路電流值穩定存在,可以對其進行比較準確的測量:三是此電流值更能代表堿錳電池實際工作時的放電性能c為了本研究的順利實施,本課題提出了一個堿錳電池四參數檢測的實驗平臺,做到對電池的開路電壓、負載電壓、電流指標、電池重量四參數的檢測。
  2. Lack of advanced experimental instrument for studying the object movement in farm machine operations is a serious problem at present. hence a high - speed photography system is established on soil bin to study the rules of moving objects. it is first time to research the moving track of the maize straw shattered on the planter by using a high - speed photography system in order to resolve the anti - blocking problem of no - tillage planter

    本文針對農機作業中物體運動試驗研究手段落後的現狀,在土槽上建立了一套高速攝像系統用於研究物體的運動規律;並針對免耕播種機的堵塞問題,首次將土槽高速攝像系統用於免耕播種機粉碎后秸稈的運動軌跡研究。
