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.

Humanism" carried out in archival information communication is not only meant to follow with interest the audience's daily practical needs of archives and esthetic demands, but also, even more basically, meant to encourage the audience's consciousness and willingness of receiving archival information rather than their involuntariness and utilitarianism. The real essence in the communication effects of archival information lies in developing the audience's high-level esthetic view, archival sensitiveness and "EQ for seizing the value of archival information. On the other hand, the humanity in archival information itself, democracilization in the society and the advances of human spirits have all laid a solid foundation for the development of esthetic culture of archives.

在档案信息传播中贯彻"人本主义"，不仅指关注受众日常功利性的档案需要和审美情趣的要求以及传播者对这些需要和审美情趣的迎合与顺应，更根本性的在于促使受众对档案信息的接受超越实用功利性和工具性行为的限定，上升到一种自觉的境况，培养和引导受众形成较高水准的审美观念，从而增强对档案信息传播的敏感度和把握档案信息意义的"情商"，通过接受档案信息触发美好情绪和有益思考，充实和完善自身，这才是理想的档案信息传播效果应有之义。

In his literary and dramatic works, Lessing expressed the thoughts to Enlighten and foster the national sprit and even to set up an integral national civilization; what"s more, he opposed the feudal separationist rule with his ideal of Kosmopolitismus. At that time, after succeeding and developing European humanist tradition, Lessing formed his religious philosophy and religious tolerance, with his rational opinion, he deepened the profundity of German Enlightenment. Furthermore, he created townspeople"s drama and advocated the realistic aesthetics. On the one hand, he praised their disposition and expressed their political desire and class interest, which made the townspeople as a new motive force to the German Enlightenment. In addition, Lessing"s Enlighten. thoughts greatly influenced the following movement—Sturm Und Drang. The essence of Lessing"s thoughts is our common valuable prosperity.In a word. Germany then greatly needed a person like Lessing, and Lessing was the child of German Enlightenment.

After calculating the internal force influence surface of assembly skew hollow slab bridge, the internal force-controlling section is attained; the transverse distribution of internal force is studied and the transverse distribution coefficient is parametric analyzed. Based on the results, relation formula of transverse distribution coefficient between skew and perpendicular bridges are fitted. Practical calculation method for the internal force calculation of assembly skew hollow slab bridge is offered. Some conclusions are drawn from comparing and analysing the internal force, bearing reaction and deformation of both assembly and monolithic skew slab bridges.
