在增重法中，试样被密封在装有干燥剂的透湿杯杯口处，然后将整套透湿杯组件放在控制环境中。

In the Desiccant Method the test specimen is sealed to the open mouth of a test dish containing a desiccant, and the assembly placed in a controlled atmosphere.

当试样面积大于杯口面积时，试样在透湿杯边缘的覆盖就成为一个误差来源，尤其是对于较厚的试样。

When the specimen area is larger than the mouth area, this overlay upon the ledge is a source of error, particularly for thick specimens.

为了保证所测试的结果具有可比性，必须保持电容探头离试样袋口相等的距离。

In order to make a comparison of test results, equal distance between capacitance detector and open side of test bag must be assured in each test.
