摘要：
A method for the construction of a positively and uniquely defined function of the probability distribution in phase space is proposed for quantum systems. As an example the probability distribution function for a quantum parametric oscillator is calculated. The method of the integrals of motion is used in calculations. The difference between the proposed probability distribution and Wigner's quasi-probability distribution is discussed. An experimental test of the method, its application to the study of squeezed states of an electromagnetic field and substance are also discussed.
