随机性

The partial periodic correlation functions are summarized, and the notion partial aperiodic correlation function is brought forward correspondingly.

这两个概念在研究序列的随机性时常被忽略且很模糊，但它们却对序列的局部随机性有很重要的影响。

Quantum theory generalizes classical mechanics to provide accurate descriptions for many previously unexplained phenomena such as black body radiation and stable electron orbits .

有人引用量子力学中的随机性支持自由意志说，但是第一，这种微观尺度上的随机性和通常意义下的宏观的自由意志之间仍然有着难以逾越的距离；第二，这种随机性是否不可约简还难以证明，因为人们在微观尺度上的观察能力仍然有限。

Many investigations show that randomicity of structures?parameter will bring large value of stochastic dynamic response of structures. Randomicity of structures?mechanics parameter may be dominant factors. Therefore, introduction of randomicity into system model of structure and using random system model are more reasonable than that of determinate system model. The work in this dissertation mainly consists of two parts.

众多的研究工作表明，结构参数的随机变异性可以引起结构随机动力响应的大幅度涨落，结构力学参数的随机性还可能成为主导因素，在结构系统模型中引入随机性的概念，采用随机结构系统模型是较确定性结构系统模型更为合理的一种选择。

In this study, we find that there are two problems when applying the techniques of discretization to obtain an approximated probability density function of the project completion time in stochastic activity networks. Namely, first, there exists neither exact data structure nor systematic scheme for the computer programming when applying the techniques of discretization; and second, error may arise from assuming independency between sub-paths in the activity network.

本研究发现在运用文献中的散式计算技术，求算随机性专案完成时间的机分配函时，存在个问题：第一，文献中既未提供明确的资结构也没有系统化的架构，足以将其转为计算机程式；第二，因为文献中的散式计算技术，皆假设随机性专案网中的各条子径彼此独，而造成明显的误差。

Through review historical cognitions on relations between complexity and randomicity, bring forth and analyzing immediate relationships between randomicity and Kolmogorov complexity from computer science, this paper tries to peel off some errors understanding on this relations and to return real relations about the them, and analyzing Gell Mann effective complexity concept, argument that two relations between complexity and randomicity, and three random instances.

本文通过对历史上复杂性与随机性关系的认识回顾，展示和分析了起源于计算机科学领域的Kolmogorov复杂性与随机性的直接关联，分析了盖尔曼的有效复杂性概念，论证了两种复杂性与随机性的关系，以及随机性的不同情况，力图剥离混合在复杂性与随机性相互关系上的一些误读和误解，还复杂性与随机性一种客观的本真关系。

The regularities of casing strength distribution were obtained by means of Latin Hypercube stochastic simulation method based on Monte-Carlo method.

By deep analyzing the tested value of the concrete strength with the rebound method and combining with the inverse regression theory,a rebound strength curve of three-parameter inverse regression is put forward.

基于对回弹法检测混凝土强度被检测量，结合逆回归理论提出了一种逆回归三参数回弹法测强曲线模型，将随机性较大的混凝土回弹值作为因变量，随机性较小的抗压强度值作为自变量，并且增加了一个位置参数，更加符合工程的实际情况。

In the curve, the concrete rebound value with wide randomness is a dependent variable, while the compressive strength value with narrow randomness is an independent variable, and a location parameter is added, so it is more suitable for engineering practice.

将随机性较大的混凝土回弹值作为因变量，随机性较小的抗压强度值作为自变量，并且增加了一个位置参数，更加符合工程的实际情况。

This paper analyzed the randomness of the relative position relation between the common vertical line of the two axes of a coupling and two centers of a coupling during installing machines,and the randomness of the position of the support plane on which a machine is installed.It pointed out the errors formed by the two randomness and illustrated the faults of the four parameters system which is used in describing the shaft alignment error of a coupling by abroad technician.

分析了机器安装过程中联轴器两轴线的公垂线与联轴器中心的相对位置关系的随机性及机器地脚支承面方位的随机性，指出了两种随机性所产生的误差，说明了国外工程界在描述联轴器对中误差时所用的4参数体系存在的不足。
