统计参数 meaning in English
statistical parameters
Examples
- By analysis the test data , the law of temperature variation in day and temperature variation in month was got ; moreover , the probability statistics mode of day temperature difference with its statistic parameter was got too . at the same time , the year temperature difference data of walls and roofs were obtained . through the field tests , the law of thermal cracks , displacement and stress in cshbb was summarized
对杭州市某一小砌块试点建筑进行了为期近一年的现场跟踪监测研究，给出了小砌块建筑的日温度变化规律和月温度变化规律，并由此得到了小砌块建筑的日温差概率统计分布模式及相应的统计参数和小砌块建筑不同方位的墙体和屋面的年温差数据；通过现场跟踪监测，也得到了小砌块建筑的裂缝发展规律及位移和应力的变化规律。 - Are uncertain and should be regarded as random variables , therefore the reinforced concrete frame is stochastic structure inherently , and then its motive equations converted to combined random differential equations for the uncertain parameters and external random excitation . these equations were solved by order - orthogonal expansion method with pseudo - excitation method , and then the statistic stochastic responses of random structure were obtained . at last , based on the stochastic cumulative damage model with double parameters developed by park , formulas were formulated for calculating structural earthquake damage probability using the structural reliability theory ( mainly jc algorithm ) in extensive random space
首先对受地震激励的剪切型钢筋混凝土结构进行建模，用随机等效线性化方法将二阶非线性微分方程组化成一阶线性微分方程组(或称之为状态方程) ；再考虑材料等参数的随机性，则状态方程成为复合随机微分方程组，将扩阶系统方法和虚拟激励方法推广并应用于这个复合随机微分方程组，求出结构的随机响应量的统计参数；最后采用随机累积损伤破坏准则，在广义随机空间内，用jc算法求解失效概率，进而求出结构的抗震可靠度。 - Because the wind load is a random action , the statistical parameters of structural response under this load can hardly obtained beforehand . however these parameters is necessary to klaman filtering as the preliminary condition . if not ? ot , this signal processing cannot be called the genuine real time optimum estimation
由于风荷载是一种随机作用，结构在这种荷载的作用下，结构响应的统计参数不可能事先得到，而这种参数却是kalman滤波的初始条件，也就不能实现真正的实时最佳估计。 - 4 . propose the method using two statistic parameters mi _ f and logl _ f in automatic term extraction system , then implement the key part of the system by using this algorithm . the results of the evaluation indicate that this algorithm is more efficient and robust than previous methods
在分析对比各种统计参数的基础上，提出了将两种统计参数mi _ f和log - likelihood联合应用到术语自动抽取算法中，并用此算法实现了术语自动抽取系统的核心模块，取得了较好的试验效果，试验结果证明了这种算法优于目前已有的算法。 - The theory of reliability is more advanced and more reasonable than the method of safe factor , but the rationality of reliability relies on the relational statistical parameter and the analytical model of reliability . so we must fully consider uncertainty of all parameters and human error during design , construction , utilization which affect the reliability
可靠度设计理论比单一安全系数法更先进、更合理，但可靠度理论的合理性依赖于有关的统计参数的选定和可靠性分析模式，所以我们必须充分考虑影响可靠度的各参数的不确定性以及设计、施工、使用过程中人误因素的影响。
