In this paper , cj20 - 25 alternating contactor is the study object . after optimization design to it , the sample has been made . the experimenters of fuzhou university tested it dynamic characteristic 本文以cj20 - 25型交流接触器为主要研究对象，采用多目标优化设计技术对其电磁机构进行了优化设计，根据优化结果加工出了优化后的接触器样品，并请福州大学有关试验人员对样品的动特性参数进行了测试。
This article analyzes the existent question of the traditional university students ' dormitory with middle corridor , and on the foundation of the predecessor studies , analyzes the university students ' psychological demand of the apartment , through the apartment plan and actualize effect of the software institute of fuzhou university , this paper proves the possibility of mare realistically optimizing the students apartment with middle corridor from the psychology viewpoint 摘要该文分析了传统内廊式高校学生宿舍存在的问题，并在前人研究的基础上分析高校学生时公离的心理需求，通过福州大学软件学院公寓的设计实践，论证了更切合实际地从心理学角度优化内廊式学生公寓的可能性。
On the basis of the item " the research of stability and deformation of high slope " , which studied by fujian highway - bureau and fuzhou university . the slope is located in yong - zhang freeways . a method based on the genetic algorithms has been put forward for the displacement back - analysis of slope , and some parameters can be identified , which provides for next stage calculation , treatment , ect 结合福建省公路局与福州大学土木建筑学院合作项目“高填路堤与深挖路堑边坡的稳定与变形研究”课题，以永（安） ?漳（平）战备公路为研究背景，以k15 + 183工点为研究对象，将遗传算法应用于深挖路堑边坡的位移反分析，把反演后的参数值代入计算模型再推求下一步的土体变形趋势，为工程预测预报提供理论依据。
