在实验中我们通过调节两光栅的有效使用面积，将两谱线的能量比例控制在1∶1左右。

The effective acreages of two gratings are adjusted to keep the energy proportion of two lines under the 1:1.

还有，打通了的空间可以大概增加10- 15%的有效使用面积，用玻璃代替砖墙或石膏板墙，也可以省下3 - 5%的空间。

Also, open up the space can be increased approximately 10-15% of the effective use of space, with glass instead of brick or plaster wall, you can save 3-5% of the space.
