摘要
在对手表密封性缺陷以及密封性的检测方法进行了一般性评述后,又有两种仪器为测量和评估检测结果提供了新的可能。一种仪器是以变形测量为依据,并消除了由此产生的一些问题,另一种仪器的工作原理是测量两个相同气压室的压力差,这种仪器比目前的仪器快捷精确。
After some general considerations regarding the methods for the leak test and the reasons for the leaks of watchs.two new test instruments are presented. These instruments offer new features for the measurement and for the evaluation of the results. One instrument is based on deformation measurement, but it eliminates some drawbacks of this method. The other instrument is based on the measurement of the pressure difference between two identical chambers, it measures faster and more accurate than former instruments.
