标题： Classical States and Their Quantum Correspondence

摘要： 我们指出经典态和量子态之间的一种对应关系，通过证明对于相空间上的每一个经典分布，都可以构造一个相应的量子态，使得在$\hbar\to 0$的经典极限下，后者相对于所有可测量的量都收敛到前者。 显示英文摘要

摘要： We point out a correspondence between classical and quantum states, by showing that for every classical distribution over phase--space, one can construct a corresponding quantum state, such that in the classical limit of $\hbar\to 0$ the latter converges to the former with respect to all measurable quantities.
