调试前：

->Processing input specifications ...
      THE PAIR PARAMETERS FOR ELECNRTL OPTION SET HAS BEEN RETRIEVED FROM
      DATABANK ENRTL-RK.

      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.

小结：
问题所在，参数缺乏：
STRUCTURE FOR COMPONENT H2O HAS NOT BEEN DEFINED.
STRUCTURE FOR COMPONENT C2H5N-01 HAS NOT BEEN DEFINED.
解决办法就是使用参数估计，见下图






调试后截图：







一切正常

我的也出现了这个问题，怎么按照上述方法调试后解决不了呢……
