CvEM::COV_MAT_DIAGONAL - a covariation matrix of each mixture may be arbitrary diagonal matrix with positive diagonal elements, that is, non-diagonal elements are forced to be 0's, so the number of free parameters is d for each matrix.

每一个混合的协变矩阵都是任意的正对角阵，也就是说，非对角位置的值必须是0，因此每一个矩阵的自由参数为d。

A novel adaptive time delay estimation approach, referred to as CAED for short, is proposed based on covariation series because the impulsive noise may usually be modeled as α-stable distribution in the application.

针对实际应用中常遇到的脉冲性噪声问题，以α稳定分布模型进行描述，提出了一种基于共变序列的自适应时延估计方法，简称CAED。

The results showed:(1)the factors which influence causal judgment were that the cause was the real cause or stimulative,the familiarity of the cause,and the covariation degree of causes with outcomes;(2)the character of questions didn't influence causal judgment;(3)causal judgment in some conditions were in accord with the probabilistic contrast model and the causal model theory,but they couldn't explain causal judgment in all conditions.

例如，在两个刺激同时出现并且之后伴随着一个结果事件出现的情况下，其中一个刺激对结果的作用可能被认为减弱了，另一个刺激被认为更易引起结果事件的产生[1]。多原因相互影响的现象，最初在动物条件反射中观察到，现在也已经在人类因果判断的实验中证实了[2]。研究因果判断中的多原因相互影响这一现象是有理论意义的，因为它证明了因果判断产生的情境重要性。

The results show the possibility of multi-level representations and attention requirement thresholds. Hidden Covariation Detection procedure is used in the latter two experiments.

后两个实验在国内首次采用非显著协变关系学习法探讨了刺激特征、学习次数和成就动机等因素对内隐学习的影响。

He life space of family caregivers turns out to be in covariation with that of people with dementia. In order to take control of caregiving and living requirements, most family caregiviers would modify the life space of the elderly carereceiver. In this modification process the caregiver's own life space also undergoes changes to different extents.

属和失智老人的生活空间属於高度相关的共变关系；大多数家属会调整老人的生活空间，好让自己得以掌握大部份的基本生活及照顾事务，少部份家属由於两人关系较难著力改变老人的生活空间，因而转以调整自己生活空间的方式，或是引入社会邻里等资源的协助，来因应不断变化的照顾需求。

To solve the problem that the-spectrum estimation performance based on covariation under the-stable noise environmentbecomes obviously worse when the distribution parameter is small,a method of fractional low-order covariance spectrum estimation was proposed.

针对在分布参数值较小时稳定分布噪声下基于共变的谱估计性能较差这一问题，提出了一种分数低阶协方差谱估计方法。

The algorithm combines thermodynamic and covariation information to assign scores to all possible base pairings. Base pairings are then predicted with the help of the iterated RNA folding algorithm based on minimum of free energy.

该方法在给潜在碱基对打分时综合了热力学和协变信息，通过基于最小自由能RNA折叠算法的多次迭代选出所有的碱基对。

You can snipe the second and third union leaders from this position.

您可以鹬第二和第三工会领袖从这一立场出发。

Aiming at the currently shortage of XML streams quality detecting, this paper proposes a new forecasting method of XML streams quality by least squares support vector machines, which is used the method of XML keys' vector matrix as windows, and vector product wavelet transform to multilevel decompose and refactor the XML streams series, that can fulfill real-time checking demand of XML quality, and ensure constraint, consist- ency and integrality. For even more adapting net load, it proposes a control strategy by weight and adaptive adjustment to ensure XML streams quality.

针对当前XML数据流质量检测存在的不足，提出构建XML键的矢量矩阵作为窗口，利用矢量积小波变换多级分解与重构XML数据流，再结合最小二乘支持向量机对XML数据流质量进行预测的一种方法，满足XML数据流质量重构时实时检测的要求，保证XML数据的约束性、一致性与完整性；为了更好的适应网络负载，采取加权与自适应窗口调整等调度策略充分保证XML数据流的质量检测。
