怎麼利用Virial equation估算等量吸附熱(Isosteric heat of adsorption, Qst)?文献的第5页说了,m and n were gradually increased until the contribution of extra added a and b coefficients was deemed to be statistically insignificant towards the overall fit, and the average value of the squared deviations from the experimental values was minimized。我的理解是要试出来的。至少要一个a0,一个b0,然后看拟合效果,既可以看图形上的线和数据点总体是否接近,也可以看R的平方。就一个a0和一个b0肯定拟合不好,然后试着加上a1,用a0,a1,b0三参数拟合,看下图形和R的平方。不好在加上a2。。。。。。直到满意。bi一样但不需要太多。可以看到两幅图中a0的绝对值明显大大于其它的ai,b0绝对值也大大于其它bi。而且a0和a1异号,a0和a2同号。。。。。。不停的变号,bi也一样,且绝对值是1/1000,1/100这样次幂级小起来。这样就拟合的可以了。查看更多
