目前真空测量的方法都是采用真空规,把它封接或粘结在真空容器上。然后在真空容器外面使用电子技术,将真空规上所获得的讯号进行放大。最后,在电压表上,刻上真空度,直接给实验工作者观察。用这方法所研制的仪器价格昂贵,测量步骤繁琐。另一方面,这是属于在真空容器内取样测量的方法,取样部份将受到测量仪器的影响, The current vacuum measurement method is the use of vacuum gauge, it sealed or bonded to the vacuum vessel. Then using electronic technology outside the vacuum container, the vacuum gauge obtained on the signal amplification. Finally, the voltmeter, engraved on the degree of vacuum, directly to the laboratory workers to observe. Instruments developed by this method are expensive and tedious measurement steps. On the other hand, this is a method of sampling measurements in a vacuum vessel, the sampling part will be affected by the measuring instrument,
