曲管气压计放置较长时间后，会由于水银氧化变质等原因，产生一些气泡，使气压计漏气，而导致读值变小。如何向曲管气压计里重新灌注水银，是一个比较困难的问题。经过多次尝试，终于找到了一个操作简便、灌注精确的方法。操作大致分成三个步骤。第一步是倒出漏气的气压计...
After the tube pressure gauge is placed for a long time, some bubbles may be generated due to oxidation and deterioration of the mercury, which may cause the air pressure gauge to leak and cause the reading value to become smaller. How to refill the mercury into the tube pressure gauge is a difficult problem. After many attempts, finally found a method that is easy to operate and accurate. The operation is roughly divided into three steps. The first step is to pour the leaky barometer...
