用文献中的兰氏体积和兰氏方程参数计算出在实测温度和实测压力下的吸附体积作为“兰氏计算值”;用LI吸附-流动方程回归处理实测值,得LI氏吸附特定参数。用LI氏吸附特定参数计算出在实测温度和实测压力下的吸附体积作为“李氏计算值”。分别计算“兰氏计算值”与“实测值”之间的平均相对误差δ_1和“李氏计算值”与“实测值”之间的平均相对误差δ_2。比较结果显示用LI吸附-流动方程能更简单精确地描述变温变压下煤吸附实验,因为δ_2<δ1。
The volume of adsorption at the measured temperature and the measured pressure is calculated as the “Rankine’s value” using the literature of the Rankine’s volume and the Rankine’s equation; and the actual value is obtained by regression of the LI adsorption-flow equation parameter. The adsorption volume at the measured temperature and the measured pressure was calculated as “Lee’s calculated value” using the specific parameters of the Li’s adsorption. The average relative error δ_1 and the mean relative error δ_2 between the “calculated Lee’s value” and the “measured” value are calculated respectively for the “calculated” and “measured” values. The comparison results show that the LI adsorption - flow equation can describe the coal adsorption experiment under variable temperature and variable pressure more simply and accurately because δ_2 <δ1.
