aspen模拟结果提示是什么意思
|
|
采用aspen做数据回归，回归不收敛，结果提示中有很长，如下，可以先拖到最后看一下哦 Data regression completed with errors ->Processing input specifications ... THE PAIR PARAMETERS FOR ELECNRTL OPTION SET HAS BEEN RETRIEVED FROM DATABANK ENRTL-RK. INFORMATION PURE COMPONENT PARAMETERS FOR SOME COMPONENTS ARE RETRIEVED FROM DATABANK. THESE PARAMETERS ARE USED WITH THE ELECNRTL OPTION SET UNLESS YOU ENTER YOUR OWN PARAMETERS IN PROP-DATA PARAGRAPHS. PARAMETER THRSWT(ELEMENT/3) RETRIEVED FOR COMPONENT H2O PARAMETER PLXANT RETRIEVED FOR COMPONENT H2O MW AVAILABLE FOR COMPONENT ZNC4H-01 IS DIFFERENT FROM MW CALCULATED FROM FORMULA (ATOMNO/NOATOM). CALCULATED VALUE IS USED. AVAILABLE MW = 183.4604 CALCULATED MW = 183.4792 ->Data Regression begins ...

Data regression completed with errors 有这么长，但是现在着重想知道下面两条的意思 （1）SSQ: 0.157998E+11 REL CHANGE: 0.252E-04 TIME: 39.79 FINAL SSQ: 0.949530E+08 （2）WARNING WHILE EXECUTING DRS CASE: "30" CHEMISTRY CALCS FAILED FOR THE 6. POINT IN DATA GROUP 30-40 : NO. ITERATIONS= 50; RMSERR= 0.153859E-02 特别是如SSQ,REL CHANGE,FINAL SSQ,NO. ITERATIONS,RMSERR这些关键词的意思，哪位高手伸出爱心援手帮帮忙啊  [ Last edited by xiaomeichen on 2011-8-31 at 15:42 ] |
