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.
误差的大小是试样厚度、边缘宽度、杯口面积、可能还包括水蒸气透过量的综合影响。
The magnitude of the error is a complex function of the thickness, ledge width, mouth area, and possibly the permeability.
应用毛细管流变仪测量了在接近实际挤出工艺条件下低密度聚乙烯熔体的流变性质； 应用流动可视化技术，观测了试样熔体流经突然收缩的轴对称口模时的入口收敛流型。
The entry convergent flow pattern was observed with flow visualization technique when the resin melt flowed through a die featuring abrupt contraction in cross-section of channel and axial symmetry.
