The main achievement is as following: Present a new software structure with insert mode based on diagram and data platform. With this structure the software can be used in various voltage levels of power networks by switching function groupware with corresponding edition. Therefore it is important to solve software universality and developability.(2) Present a new idea that any operating condition is combination of running mode of plant or station, power supply topological and rules of equipment maintenance. This idea is very useful at simplifying setup and choice of operating conditions and ensuring calculation result correction.(3) Present a new idea of protection setting examination and rectification. Protection setting examination is used to examine the selectivity、 sensitivity and speed under certain operating condition, and pass an opinion whether these settings are wrong;Setting rectification is used to calculate new relay settings when error is found in setting examination.(4) Point out that interaction design is the key step in developing power system application software,which can secure usability.

I put it allin the best order I could, but you can read it diagonally if you like.

我按照自己的思路排列了顺序，不过，你可以根据自己的喜好有选择性地阅读。

Results:①No differences were observed between two groups on the distribution of coronary vessel diseased (narrowing≥50.0% of diametre)(p＞0.05).Left ventriculography did not show that inferior wall motion were strikingly diminished in the both Group A and Group B.

结果：①选择性冠状动脉造影显示冠状动脉病变(狭窄≥50.00%)支数在两组间的分布无显著差异(P＞0.05)；左心室造影两组均未见下壁运动明显减弱。

At present, studies on and applications of chiral diamine s have been regarded as one of the most remarkable fields in catalytic asymmetric reactions.

手性二胺作为具有良好催化活性和对映选择性的手性配体或手性辅助剂，在多种催化不对称反应中已经得到广泛应用，并取到了很好的研究成果。

The recognition capability and adsorption rate of MIP can be significantly enhanced by selective modification.Separation factor could be increased from 1.60 to 3.06 after modification when naringenin was chosen as competitive molecules, and the time needed for adsorption equilibrium could be reduced from 100 min to 60 min.Within a certain range, increasing template molecule concentration or diazomethane dosage, or adopting solvent which had weaker hydrogen bond action with template molecules could all improve the modification effect.

结果表明，选择性修饰能明显提高MIP的识别能力与吸附速度，以柚皮素为竞争分子，分离因子可从修饰前的1.60提高到修饰后的3.06，吸附平衡时间从修饰前的100 min降低至修饰后的60 min；在一定范围内提高模板分子浓度，增大重氮甲烷用量，采用形成氢键能力较弱的溶剂，均能提高修饰效果。

Molecularly imprinted polymer using quercetin as template molecules, methacrylic acid as functional monomers, ethylene glycol dimethacrylate as crosslinking agent were prepared, and the binding sites of MIP were selectively modified with diazomethane.The effects of template molecule concentration, solvent and diazomethane usage on modification were discussed.
