查询词典 group method

With a representation of the rotation group induced by the anti-commutative, self-inverse matrices the transformations named by Foldy-Wouthuysen, Cini-Taschek,Chakrabarti and the others are treated from a unified viewpoint. A new transforma-tion is found. Some applications of this method in the eigenvalue problems are demon-strated.

我们找出了由反易自逆矩阵荷载的转动群表示，统一地推广处理了Foldy-Wouthuysen，Cini-Tauschek，Chakrabarti等提出的各种变换；建立了一个几何图像，借助于它可以很容易地找到所要求的交换；举例说明了这方法在本征值问题中的应用。

The following conclusions have been reached, milk has an obvious absorption in the mid-infrared band, and the locations of the absorption peak are consistent with the attributes of molecule functional group analysis and the information from FOSS Company; the effects of the factors on the repeatability are below 3‰; For the quantitative analysis, the method of factorial design is applied to optimize the calibration set. The outliers are determined considering the residual variance distribution. The correlations are 0.990 and 0.986 for fat and protein, respectively. The Root Mean of Square Error of Prediction is 0.121 and 0.111 for fat and protein, respectively. With the application of the methods of wavelengths selection, the numbers of wavelength is decreased greatly from 3301 to 100. The speed is accelerated and the accuracy of the calibration is improved to some extent.

结果表明：牛奶在中红外的吸收特性明显，吸收峰的位置与分子结构的谱带归属以及乳品分析仪器的成功厂商FOSS公司提供的资料基本一致；各种因素对光谱测量影响的CV值基本可以控制在3‰以下；在定量检测中，通过析因设计方法优选校正集样品，结合样品的残差图确定奇异点，脂肪模型和蛋白模型的相关系数分别为0.990和0.986，预测均方根误差分别为0.121和0.111，而在采用波长选择对模型进行优化后，波长从3301个减为100个以内，加快了运算的速度，同时还在一定程度上提高了模型的精度。

While as the most promising receiver-driven layered multimedia transmission scheme, RLM with shared-learning scales with the size of the group, but it also raises a few questions. To address this problem, we enhanced the RTP protocol so that receiver can estimate the round-trip time in much the same way as the method specified in RTP standard which is adopted by sender to calculate the RTT.

为此我们通过对RTP协议进行加强，使得接收者也能够采取与原有的RTP协议中发送者对于往返传输时间的估计类似的方法来估计到RTP源的往返传输时间RTT，并根据TCP吞吐量模型计算出同等条件下的TCP连接占用的带宽，从而动态地选择加入或者丢弃某层。
