中文摘要：

利用分束器和探测技术研究了在两体混合压缩态条件下蒸馏性与纠缠的关系问题，利用负度和对数负度测量蒸馏前后的纠缠变化。研究结果表明，压缩参数的取值是影响纠缠的一个重要因素。文中还研究了光子扣除分束器的透射系数对纠缠的影响。

英文摘要：

The problem of entanglement with distillability of a two mixed squeezed states using beam splitters and detection techniques were studied .The negativity and logarithmic negativity to measure the entanglement before and after distillability were used .The results show that the value of squeezed param-eter is an important factor to effect the entanglement .Furthermore, the transmission coefficients of the photon-subtraction beam splitter were also considered .
