摘要
本文利用态叠加原理移去压缩光场态中的真空态，研究了真空态与压缩的关系。结果表明，无限维空间态的压缩与真空并存，有限维（＞２）空间态的压缩不依赖于真空的存在，显示出压缩效应产生的复杂性．另外，真空态的消失对亚油松分布的产生或增强是有利的。
Using the principle of state superposition, we study the relationship between shiping and vacuum state by means of removing vacuum state from squeezed states. The result shows that the squeezing for a squeezed state in infinite dimension space always accompanies with vacuum state, but in finite dimension (> 2)space, the squeezing is independent of the existing of vacuum state, which displays the complexity of the production of squeezing. In addition, the vacuum state removed in a state is advantageous to production or enhancement of sub-poissonian distribution.
