For increasing the effective material peak - value power ( empvp ), solving the contradiction between enhancing the pmsm ' s flux - weakening capability in the electromotor state and reducing the pmsm ' s connatural adjustment ratio in the dynamotor state and improving the efficiency of the pmsm, some solving method are taken as follows : the influence of length / diameter ratio to the empvp is analyzed, and the optimum size of length and diameter is chosen
主要是從提高電機的有效材料峰值功率、解決pmsm提高電動機運行狀態時的弱磁擴速能力和減小發電機運行狀態時的電壓調整率之間的矛盾及提高電機的效率著手，分析了長徑比、氣隙長度對有效材料峰值功率的影響，並確定了它們的最佳尺寸。 -
The thesis is devoted to exploiting a permanent magnet synchronous machine ( pmsm ) for the parallel hybrid electric vehicle ( phev ). three parts are included as follows : at first, in the electromotor state, the current control strategies of pmsm are determined. giving the elementary method for solving the contradiction between enhancing the pmsm ' s flux - weakening capability in the electromotor state and reducing the pmsm ' s connatural adjustment ratio in the dynamotor state
本課題的研究工作主要圍繞開發一臺並聯式混合動力電動汽車（ phev ）用永磁同步電機（ pmsm ）展開，所作的工作主要包括以下幾個部分：首先，確立了phev用pmsm電動機運行狀態時的電流控制策略，針對pmsm在電動機運行狀態時提高弱磁擴速能力和在發電機運行狀態時減小固有電壓調整率的相互矛盾，提出了初步的解決方法。 -
My reasons for the formation of the middle class are : 20 - odd years, as china ' s economic structure and reform and opening up in depth, the original relatively closed and relatively simple social strata structure has undergone great changes ; political civilization construction and transparent government building, state of citizens in political life, economic life and social life interfere with the further weakening, subject to " common prosperity " target distribution system rationalization, the sound socialist legal system, improve the social security system so that the rise of the middle class quietly and causing social concern
2004年中國社會科學院陸學藝領導的「當代中國社會階層結構研究」課題組依據幾年來對中國社會結構變遷中社會分層結構的經驗研究和思考，借鑒國外有關理論，對當前中國社會中間階層給出了一個初步的研究界定:所謂中間階層， 「包括擁有一定私人生產資料的自雇者和中、小僱主（如中、小私營企業主）群體。其間的主體是指佔有一定的知識資本及職 -
