没有:shuai:我现在只知道Qt和t，请问应该怎么做log(Qe-Qt)对t图呢？
应该是求得Qe和常数K1。不好意思
您好，我想问下您说的orign8.6的自带拟合方程作图，是将Qt和t的值输入orign，然后非线性拟合做出的图就是log(Qe-Qt)对t图嘛？我刚开始的时候也像你一样迷茫，同学给我推荐了，上面很多牛人分享的科研经验，对新手很有帮助，你也可以下载来试试！
将Qt和t的数值分别输入到软件当中，之后通过Boxlucas1拟合出你需要的参数，这里所形成的图只是Qt对t的图。不一定一阶方程拟合的效果好，你可以试下二阶和Elovich模型试下。
请问拟合准二级动力学方程用哪个拟合啊，那么多公式，找不到
origin中可以自己编辑公式。具体教程你在网上可以查下。
以时间t为横坐标，log(Qe-Qt)为纵坐标用orign作图就行
那Qe是怎么求得啊？
在24h, 48h,或者更长的时间下进行吸附，然后测吸附量就是Qe
一级动力学不是靠t和Qt来拟合求Qe的么？
总感觉延长时间虽然没错，但觉得这样出来的Qe很不合适啊，Origin能拟合出来么
请问楼主？你现在会做了吗？我也在做这个啊！那个准一级动力学方程的Qe咋弄呢？？？？、跪求！
那拟合出来的截距不是lgqe吗，那和之前用平衡吸附量不是矛盾吗？求楼主解答啊，怎么解决的最后
假设Qe为无限长时间测定的吸附量将Qe值代入公式做线性方程，也可以在origin中编辑方程做非线性方程拟合
感觉即使是达到平衡也不是绝对平衡还是会有波动的，究竟该取哪个值作为平衡量呢？
