摘　　要：在τ质量实验测量之前对多种测量方案进行了细致的ＭｏｎｔｅＣａｒｌｏ研究，并进行了比较．确定τ质量测量实验采用最大似然法，并给出可能的测量精度．研究了包括探测效率、束流能散等诸多因素对实验的影响，同时对实验的实现提出要求．Before the τ mass experiment, several measuremental strategies were studied in detail by Monte Carlo simulations. After they were widely compared, the likelihood method was suggested to determine the energy points and the possible measuremental accuracy has been given. The effects of many factors to the measurement were simulated, such as the event selection efficiency, energy spread etc, and necessary requirements were proposed to the experiment.
