Then from the expression of gas well deliverability in pseudo-steady state flow, there can have the expression of gas PI with and without high speed non-Darcy percolation.
同时还对拟稳定流动气井产能公式进行推导，推导出考虑高速非达西渗流、不考虑高速非达西渗流的采气指数的表达式。
Ln and now I've got log of PI over p, and I'm just going to use the ideal gas law.
现在有，现在我要用理想气体定律。
In order to keep the pressure of the gas import as a fixed value, the design used a PI-conditioning.
为了保持原烟气入口压力为定值，本设计采用PI调节。
The values, of oxygen content in the flue gas measured by a ZrO2 sensor are sent out as electric signals by a transmitter, They are converted into pressure signals via PI regulator.
由氧化锆探头测出烟道气中的氧含量，经氧量变送器输出电信号，用调节器进行PI运算，再转换成压力信号。
