1·In being of testing methods, accurately noting exiguity changes of permeability is very hard, and exists errors are difficult to avoid in artificially noting.
在现有的测试方法中，很难精确记录透气性的微小变化，且存在人工记录过程中难以避免的误差。
2·Secondly , I discuss the detecting method of the exiguity capacitance, and introduce the principle of the compensating for the te…
接下来，介绍了微小电容的检测方法以及温度补偿原理。
