在漏孔校准过程中，通过调节稳压室中的压力，很容易使标准气体流量与漏孔漏率非常接近或相等，从而避免四极质谱计的非线性影响。
In calibrating the leak, the pressure in the ballast chamber can be precisely controlled in such a way that the standard gas flow through the orifice is close or equal to the leak rate.
这些传感器很容易调准，且使用非常明亮的红色发光二极管来安装。
These sensors are easily aligned and installed using the extremely bright red sender led.
