By the comparison of calculation result with the tests result , it was concluded that the method to calculate the year temperature difference and day temperature difference from weather data was feasible . by this method , it was got that the statistic parameters of combined temperature difference in base period and the reliability to different anti - crack index was calculated the combination of thermal effects and load effects was considering in this paper 对多年气象资料进行了统摘要浙江大学博士学位论文2003计分析，将其转化为结构的年温差和日温差，并与实测值进行了比较;在此基础上得到了设计基准期内的结构组合温差统计参数以及不同抗裂指标所对应的可靠度。
Appraising the existing structural reliability is an important embranchment of the theory about reliability . today , the methods of appraising the existing structural reliability that is used in our country generally belong to applied methods , but the expression about verifying the bearing capacity in this method is educed according as statistical information of future structures . because the statistical property of existing structural loading and resistance is obvious different form the future structure , the methods ca n ' t reflect the statistical property of existing structural 现有结构可靠性评定是结构可靠性理论的一个重要分支，我国目前的建筑物可靠性评定方法总体上属于实用鉴定法，但这种方法的承载力校核表达式是依据拟建结构的统计信息得出的，由于现有结构的荷载、抗力等的统计特性明显不同，因此这种方法难以合理反映现有结构的具体特性，而应根据荷载、抗力等的具体统计参数，建立现有结构的承载力校核表达式。

The current data storage module of intrusion detection system ( ids ) is mainly constructed by hand . for example , people construct the anomaly detection system by selecting the statistic parameters based on their institution and experience , and write the intrusion rules of the misuse detection system by analyzing the attack process and system leak 当前的入侵检测系统的数据存储模块大多是基于手工建立的，系统构建者依靠自己的直觉和经验来选取异常检测的统计参数，或者需要在分析攻击过程和系统漏洞特点的基础上手工编写相应的入侵规则，因此系统的自适应性很差。
