人民教育出版社出版的初中物理課本下册(1953年8月原版)第60節和東北人民出版社出版的初级中学教科書物理学下册(1952年版)第120節“電動机的應用”中都說到了應用电动机于电车的装置,並且晝出了电車電路圖。人民教育出版社的課本这樣寫道:“……電流從發電廠的發電機裹流出,經過架空線,從弓子流到電車里的電动机上,然後從下面的铁轨流回發電廠。電动机的轉動就使電車沿铁轨前進。……”同時東北人民出版社的也这樣寫道:“……電流的路徑是這樣的:電流從架空线顺着弓子下來,到電車司机駕駛的操縱台K上,從这里到電動機M_1及M_2,然後通過車輪而
People’s Education Publishing House published junior high school physics textbook Volume (August 1953 original) section 60 and the Northeast People’s Publishing House published junior high school physics textbook book (1952) section 120 “Motor Application” Speaking of the application of electric motor in the tram installation, and daylight tram circuit diagram. People’s Education Press textbook reads: “... current flows from the generators in the power plant, through the overhead lines, from the bow to the motor in the train, and then back from the rail to the power plant. Turn the tram along the rails ... ... ”At the same time Northeast People’s Publishing House also wrote:" ... current path is this: the current from the overhead line down the bow down to the tram driver’s console K From here to the motors M_1 and M_2 and then through the wheels
