It introduced research actual state of genetic algorithms , enumerated the calculation result of global optimized crossover and mutation , gave the mostly program of binary system character string coding and using numerical model and the practical data checked out the effectiveness of mixed inversion algorithm 文中介绍了遗传算法的研究现状,例举了全局寻优交叉和变异的计算结果,给出了二进制字符串编码的主要程序段,用数值模型与实际资料验正了混合反演算法的有效性。
This paper defines the sync objects and explains how to monitor and detect their changes . as to support various kinds of transmission ports , we add data check - up to improve slip agreement . at the same time the request - reply mechanism based on serial number is designed to retransmit the data which has mistakes or be lost 本文阐述了同步数据对象的定义以及对其更新的监听策略;为了向下兼容各种传输端口,改进slip协议,增添了数据校验;同时采用基于流水号的应答机制,保证了出错、丢失数据包的重发。
This paper analyse the feasibility and necessity of examine and repair about the qiangui co . ltd of generate electricity base on the frmework of guizhou wire network and the run state and exerience of the factory . at the same time , in the base of the lucubrate and analyse of stats examine in domestic and abroad , this paper has analyse the abrupt librate of steamer generator by online data check in pancountry power plant . it acquire obvious effect and prove the applicability and feasibility about the examine in power plant by take correspond measures to ensure the normal operate of the set 本文根据贵州电网的结构形式以及黔桂发电有限责任公司机组的运行状况和经验,进行了黔桂发电有限责任公司实行状态检修的可行性和必要性分析,同时在深入研究分析国内外状态检修技术基础上,对盘县发电厂汽轮发电机组突发振动事例用在线检测数据进行分析、采取相应措施处理,使机组正常运行,取得了明显的成效,同时也证明点检与状态检修在火电厂的适用性和可行性。
With expansion of database use , relational database not only is approved by the masses of users , and people put forward new request constantly with this , hope and can make high quality of analysis of data in time . in addition datum that need to be dealt become more and more large , and mistakes of data appear unavoidably among them . so data check - up becomes one of the main subjects studied 随着数据库应用的扩展,关系数据库不但得到广大用户的认可,而且人们对此不断提出新的要求,希望能够对数据及时做出高水平的分析;另外,由于需要处理的数据越来越大,在其中出现数据的差错是不可避免的,因此数据校验也成为研究的主要课题之一。
