许多中学生在学习物理时,常常为解答论证题而感到头痛。这类题目的解题特征是通过公式的推导和证明,并进行讨论,从而得出题目要求的结果。由于解论证题要求说理充分,论点明确,并借助数学手段进行逻辑推理,故牵涉到的 Many middle school students often feel headaches in answering arguments when studying physics. The problem-solving feature of this type of topic is the derivation and proof of the formula, and the discussion is carried out to obtain the result of the problem. Because the arguments for the solution arguments are full of arguments, the arguments are clear, and logical reasoning is done by means of mathematics, so it is involved.
