由“人民教育出版社物理室”和“中国教育学会物理教学研究会”编著的现行初三物理课(?)有这样一段话:“在不能预先(?)电流大小的情况下,要先拿电路的一个线头迅速试触电流表的接线柱,看看指针的偏转是否在量程之内,如果超出量程,就要改用更大量程的电流表”。由“人民教育出版社物理室”编著的以往的初三物理课本148页却有这样一段话:“在不能 The current junior physics class (?) edited by the Physics Institute of the People’s Education Press and the Institute of Physics Teaching of the Chinese Education Society has such a statement: ”If the size of the current cannot Next, we must first take a wire of the circuit and quickly test the terminals of the ammeter to see if the deflection of the pointer is within the range. If the range is exceeded, we must use a more extensive ammeter. The 148 pages of the previous third-year physics textbook edited by the People’s Education Press Physics Department contained the following passage:
