通过构造反例,首先指出＂限制辐角法＂在计算单值分支时的使用误区;其次,建立＂限制辐角法＂的使用条件,从而拓宽＂限制辐角法＂的使用范围,保证单值分支计算结果的唯一性.此外,给出＂限制辐角法＂三个新的应用实例.

英文摘要：

The method of＂limiting argument＂is one of the two most commonly used methods for the calculation of a single-valued branch.Through constructing counter examples,the misuses of the method of＂limiting argument are pointed out for the calculation of a single-valued branch.The conditions for the use of the method are defined thus to expand the applicable scope of the method of＂limiting argument＂so that the uniqueness of the computational result is guaranteed.Moreover,three new examples which can be solved by the method of＂limiting argument＂are presented.
