water vapor transmission

基本解释

A bag designed to restrict the transmission of water vapor and used to pack finished PCB.
设计用于限制水蒸气迁移的包装成品PCB的袋子。
The waterproof breathable fabrics should have a high capacity for water vapor transmission nd water resistance.
防水性能和透湿性能达到和谐统一是防水透湿织物需要解决的关键问题。
This paper introduces a new apparatus and method that suits to measuring the water vapor transmission rate (WVTR) of wound covering materials.
介绍了一种新型的测试修复材料水蒸汽透过性（WVTR）的装置和方法。
