Oxygen gas transmission rate ( O2 GTR ) is determined after the package has been mounted on a test fixture and has equilibrated in the test environment.
氧气透过率（O2 GTR）是将包装物固定在测试装置上并在测试环境中达到平衡后测定的。

The driving device has the advantage that when the fixture stand rotates, air pressure pipes which supply pressure gas for an air pressure structure can not be winded together.
该传动机构具有可使夹具架台在旋转时，该供应气压机构高压气体的气压管不会卷绕在一起。
