等比

Many parameters are required to describe their performance, which is transmission ratio, extinctivity ratio, angle of view field, splitting angle, etc.

激光偏光棱镜技术参数较多，透射、消光、视场角、束角、长度孔径。

It is therefore important to select the appropriate inlet liner, inlet temperature, injection technique (fast autoinjection is recommended), solvent, column installation and split ratio.

此应选择合适的进样衬管、汽化温度、进样技术（荐使用快速自动进样）、溶剂、色谱柱安装位置和条件。
