一般说来,在解物理题时总有一种(或一些)方法属基本方法,如定义法、公式法、分析法等。这种方法思路通常比较明显,解题者应当熟练掌握,这是能力培养的基础。但基本解法不一定是最佳方法。有时,由于所给问题的特殊性,可以寻找出一种(或一些)简捷解法。这就 In general, there is always one (or some) method that is a basic method when solving a physical problem, such as a definition method, a formula method, an analysis method, and so on. This approach is usually more obvious, problem solvers should be proficient in mastery, which is the basis for capacity development. But the basic solution is not necessarily the best method. Sometimes, due to the particularity of the given problem, one (or some) simple solutions can be found. This is
