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.
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 one embodiment, the existence of a leak is detected by looking for usage patterns wherein water or gas is always being used, at least at a low rate.
在一个实施例中，通过寻找使用模式检测泄漏的存在，在该使用模式下水或气体总是正被使用，至少也是以低速率被使用。
Gas leakage was studied experimentally and theoretically to improve the precision of the analytical model of the leakage rate for the leak-before-break technique.
