测量压力的仪表通常处于大气环境中,不能直接测量出绝对压力,显示的是绝对压力和当时当地大气压的差值。
Generally, the gage is put in the atmosphere, it can only measure the difference between the absolute pressure and local atmospheric pressure. It can not give out the absolute pressure.
并以此推导出压力时间的绝对校准公式,经实验验证,得出绝对校准模型是稳定可靠、有实用价值的结论。
At the same time, the absolute calibrating formula is deduced, a conclusion that the absolute calibrating model is stable, reliable, practical and valuable is verified by...
