flexible barrier material的意思|示意

The results show that rigid material has a better effect than flexible one in isolating vibration, so the former should be selected as barrier material in engineering.

研究表明，刚性材料比柔性材料具有更好的隔振效果，在隔振设计时应选择刚性屏障材料；

Therefore, water vapor permeability of flexible packaging material (or barrier) of the test of testing more and more important in the packaging.

因此，对软包装材料透气透湿性（或阻隔性）的测试研究在包装测试中越来越重要。
