摘要： The actual flow rate of gas to the solid-sample container or to the gas reservoir can be precisely obtained according to variances in the pressure of the gas reservoir without directly adjusting the flow rate precisely. The volume of gas not adsorbed in the sample container can be obtained from the pressure in the sample container. The adsorption can easily be determined from the difference between the flow rate of gas and the volume of gas not adsorbed in the sample container. Even if the flow rate fluctuates, the adsorption can precisely be obtained. The desorption can easily be obtained in the same way. Gas is exhausted from the gas reservoir in advance. When desorbed gas in the sample container is continuously exhausted to the gas reservoir, the pressure in the gas reservoir is measured. Since the adsorption and desorption are thus precisely obtained, the adsorption or desorption isotherm can be drawn by plotting the pressure at each point of time and the corresponding adsorption or desorption of the solid sample. Consequently, the surface area, pore diameter distribution, pore volume and the like of the solid sample can precisely be calculated.

摘要翻译： 可以根据气藏的压力差异精确地获得固体样品容器或储气罐的气体的实际流量，而不需要精确地调整流速。 未吸收在样品容器中的气体的体积可以从样品容器中的压力获得。 吸附可以容易地根据气体的流量与未吸附在样品容器中的气体的体积之差来确定。 即使流量波动，也能够精确地获得吸附。 解吸可以很容易地以相同的方式获得。 预先从气藏中排出气体。 当样品容器中的解吸气体连续排出到储气器时，测量气体存储器中的压力。 因为这样精确地获得了吸附和解吸，因此可以通过绘制每个时间点的压力和固体样品的相应吸附或解吸来绘制吸附或解吸附等温线。 因此，可以精确地计算固体样品的表面积，孔径分布，孔体积等。
