The nonequilibrium statisticaloperator (NSO) of the system is constructed and a series of macroscopic equations for its particle number, momentum, energy, force aad entropy etc. are derived.
构成了此体系的非平衡统计算符，进而导出其粒子数、动量、能量、力和熵等一系列宏观方程。

We discuss the quantum statistical properties of these states and relate these properties to the displacement operator.
本文讨论了这种位移叠加态的量子统计性质及其与位移算符的关系。

In the quantum statistical theory, the density operator is introduced in the statistical system. The expectation value of an obeservable can be obtained by the use of the density operator.
