摘　　要：对文献[4]的结果作了进一步推导,用纠缠态表象方法计算了对双模压缩真空态第一个模场作正交振幅分量测量的结果,发现第二个模塌缩到一个压缩态,其显式被导出。Based on the subject p makes some new profound mode field of a two-mode in Ref. [4] （Acta Sinica Quantum Optica V. 8 （2002） 47） this paper discussions. It calculates the result of the quadrature-amplitude measurement on the firstsqueezed vacuum state via the entangled state representation, and it is shown that the second-mode field collapses to a single-mode squeezed state, whose explicit form is derived.
