The objectives of our statistics programme are to equip our students with adequate statistical theories and methods , to help them master real - life statistical applications , and to prepare them for promising careers after graduation 统计课程的目的是要教导学生足够的统计理论和方法,让他们有效掌握解决实际统计问题的窍门,为他们毕业后的理想前途作好准备。
To reduce huge computation of the traditional stochastic optimization methods for engineering optimization , approximation model methods with acceptable accuracy for engineering design are developed based on the statistical theory 摘要针对在工程中完全采用随机类优化方法寻优时计算量过大的问题,应用统计学的方法发展了计算量小、在一定程度上可以保证设计准确性的近似模型方法。
Abstract : the relation between material strength , toughmess and other physical parameters was inferred by means of dislocation theory and statistical theory on fracture , and a comparison was made between the inferred calculation result and theexperiment value 文摘:利用位错理论和断裂统计理论推导出强度和韧性与其它物理量之间的函数关系,并将推导的计算结果与实验值进行了比较。
The main work could be stated as follows : in chapter 1 , the main contents of fd , the classification of various detection methods and prospects are summarized , especially the history and status about detection methods based on statistical theory 全文由以下五章组成:第一章为绪论,阐述了故障诊断法研究内容,各种方法的分类及发展趋势,特别是对基于多元统计理论的故障诊断方法的发展和现状进行了完整的综述。
Thus realize to the different kind of fibres in the raw cotton that divides picking up automatically . the algorithm . of differentiating of the software is designed because of the statistical theory , divide into three pieces of module : pretreatment module , characteristic draw the module , differentiate the module 软件的判别算法是基于统计理论设计的,分为三个模块:预处理模块、特征提取模块、判别模块。
