Q值计算法是评价联合作用性质的常用方法之一。但目前的评定Q值标准由于所依据的Bliss联合作用传统分类法的不足,或自身的缺陷,因而不能适应实际应用的需要。本文基于Moshkovsky联合作用分类理论和Finney改良模型,提出一个新的Q值评价系统。此系统弥补了现标准的不足,并且计算简便。据此以实例与Finney改良模型计算结果作了比较,得出相同结果。最后本文对现行Q值评价标准的不足作了讨论。 The Q value calculation method is one of the commonly used methods for evaluating the nature of the joint action. However, the current assessment of the Q-value criterion cannot be adapted to the needs of practical applications due to the deficiencies of the traditional classification based on the Bliss joint action or its own deficiencies. Based on Moshkovsky’s joint action classification theory and Finney’s modified model, this paper proposes a new Q value evaluation system. This system makes up for the deficiencies of current standards and is easy to calculate. Based on the results of the comparison with the Finney improved model, the same results are obtained. In the end, the paper discusses the deficiency of the current Q value evaluation criteria.
