附件中时模拟和转化的数据文件（PROII9.0），常压主产汽柴油，减压产柴油和蜡油；请高手帮忙看下是什么原因不收敛？
http://meng.horse/xwb/images/bgimg/icon_logo.png 该贴已经同步到 onom54783的微博 我也来学一下 没人知道吗？ALPHA是啥意思 本帖最后由 蓝山居士 于 2014-1-20 11:12 编辑
α 是一个乘数，其绝对值越小，说明内圈收敛很差，绝对值接近或等于1说明内圈收敛很好。
收敛历史中，α 很小，计算机重置多次仍无法改变，建议检查规定。
看了你的模拟文件，里面错误很多，若你是做的例子，请上传源文件，如果是模拟实际装置，请上传工艺参数，要求。。
