用Aspen中的property estimation估算C9H20O2Si的物性？ 运行时出现如下警告，但是不能得到结果： processing input specifications ... * warning in physical property system the following conventional components were not in a data bank. check data bank names for spelling. cid data bank name u1 c9h20o2si * warning in physical property system functional group generation for the unif-lby method cannot be completed for component u1. the following atoms were not matched: si 1 o 3 o 5 the functional groups generated group number no. of occur. group number no. of occur. 1015 3 1010 5 1005 1 * warning in physical property system functional group generation for the unif-dmd method cannot be completed for component u1. the following atoms were not matched: si 1 o 3 o 5 the functional groups generated group number no. of occur. group number no. of occur. 1035 5 1030 1 1015 3 * warning in physical property system functional group generation for the bondi method cannot be completed for component u1. the following atoms were not matched: si 1 the functional groups generated group number no. of occur. group number no. of occur. 153 1 121 2 102 1 101 5 100 3 * warning in physical property system functional group generation for the parachor method cannot be completed for component u1. the following atoms were not matched: si 1 the functional groups generated group number no. of occur. group number no. of occur. 148 1 115 2 102 1 101 5 100 3 * warning in physical property system functional group generation for the reichenb method cannot be completed for component u1. the following atoms were not matched: si 1 the functional groups generated group number no. of occur. group number no. of occur. 100 3 109 5 110 1 118 2 - property constant estimation completed 有哪位知道问题在哪里吗，我是用general输入的分子结构查看更多
