不确定性

This paper considers a class of uncertainties with the polynomial function form of perturbation parameters, which is analogous to a fact that part information is known for some uncertainties.

This paper introduces a modified fuzzy decision tree model. Firstly, the data are fuzzed by the use of optimal division point with optimal division entropy. Secondly, uncertainty theory of fuzzy math is introduced and a tree is built according to uncertainty of classification and creation rule. Finally, each unit can be detected about whether or not it is a fraud according to rule match method.

介绍了一种改进的模糊决策二叉树模型，即采用最优分割熵方法确定最优割点来对数据模糊化，引入模糊数学中的不确定性理论，依据分类的不确定性建造树，生成规则，在此基础上利用规则匹配的方法检测任意的样本数据是否为欺诈数据。

Then we establish a polynomial equation representing the relation between the distance of CCD apart from human face and the gap of human eyes in the CCD image through a set of experimental data.

最后是探讨CCD拍摄的不确定性，对影像量测工作可能造成的影响，并藉由统计的方式计算拍摄不确定性的范围，以调整齿轮尺寸的公差，提高量测的可信度及检验的准确度。

The mean values and variance values of the random temperature field...

通过算例分析了各个不确定性参数的不确定性对温度场响应的影响，计算结果表明该法的可行性和合理性。

The uncertainty about the ultimate technical feasibility of reanimation may very well be dwarfed by the uncertainty in other factors, such as the possibility that you deanimate in the wrong kind of way (by being lost at sea, for example, or by having the brain's information content erased by Alzheimer's disease), that your cryonics company goes bust, that civilization collapses, or that people in the future won't be interested in reviving you.

复苏的最终技术可行的不确定性与其他不确定性因素相比，几乎可以忽略不计。比如，你的生命流失在一个错误的地方（像失踪在海上或大脑的信息内容被阿尔茨·海默氏病删除），你的冷冻复苏公司破产，文明崩溃，或者未来的人们没有兴趣恢复你。

Using the singular value decomposition of matrix, the uncertain fuzzy systems can be united to the model with norm-bounded structure parameter uncertainties.

利用矩阵奇异值分解和线性变换，将不确定性模糊系统归一化为具有界范数约束的结构参数不确定性的模糊系统模型。

The feasibility of this method has been validated by the solid rocket motor case uncertainty design.

以固体火箭发动机燃烧室壳体不确定性设计为算例，验证了该不确定性设计方法的可行性。

According to the characteristic of stochastically perturbed systems,simulation research is performed and the validity of obtained result is illustrated.

由于实际中模型不确定性对系统性能具有很大的影响，所以不确定性的描述和鲁棒控制设计一直是控制领域的一个研究热点[1]。

Considering the uncertainty of the estimating reliability in the model, the theory of Bayes disk decision is used to solve the problem. The expected utility function is used to measure the uncertainty of the estimating reliability, and the Bayes decision rule for stopping reliability growth test is defined. In the end, an example is given to validate the feasibility of this method.

考虑到可靠度估计的不确定性，采用贝叶斯风险决策技术，通过期望效用函数量化可靠度的不确定性，并定义了停止可靠性增长试验的贝叶斯决策规则，最后给出了一个应用实例验证了方法的可行性。

Significant progress has been made by Dalibard,Dupont-Roc and Cohen-Tannoudji in 1982,who argued that there exists a symmetric operator ordering between the operators of atom and field that renders the distinct contributions of vacuum fluctuations and radiation reaction to the atom\'s spontaneous emission and energy shift separately Hermitian.

这种不确定性的根源来自于相互作用哈密顿量中原子和场算符的排序问题。1982年，法国物理学家Dalibard，Dupont-Roc和Cohen-Tannoudji提出原子和场算符对称排序的方法，从而消除了这种不确定性，使得真空涨落和辐射反作用对原子自发辐射和能级移动的贡献都是厄米的。

With Death guitarist Schuldiner adopting vocal duties, the band made a major impact on the scene.

随着死亡的吉他手Schuldiner接受主唱的职务，乐队在现实中树立了重要的影响。
