A generalized quantum distribution function is introduced. The corresponding ordering rule for non-commuting operators is given in terms of a single parameter. The origin of this parameter is in the extended canonical transformations that guarantees the equivalence of different distribution functions obtained by assuming appropriate values for this parameter.

翻译：引入了通用量子分布函数。 对非组合运算符的相应排序规则用单一参数给出。该参数的起源是延伸的剖面变换,这种变换保证了通过假设该参数的适当值而获得的不同分布函数的等值。
