A novel method, Block SAPOR, is proposed for MOR analysis of RCS interconnect circuits.

在大规模RCS互连电路降阶分析方面，本文提出了一种基于块二次Arnoldi过程的降阶算法Block SAPOR。

These lines take on special significance when we learn that in the rites of higher initiation in the Satanist cult an "enchanted" sword which ensures success is sold to the candidate.

这些字句有特殊意义：在撒但教的晋阶祭仪中，一柄施了巫术、能确保成功的剑，会被卖给晋阶者。

"The slope averages about 1 in 30, but contains steep, probably vertical, cliffs, and gentle sediment-covered terraces , and near its lower reaches there is a long tailing-off which is almost certainly the result of material transported out to deep water after being eroded from the continental masses."

斜度的平均坡度是三十分之一，但也有陡峭的甚至是垂直的悬崖和坡度不大的覆盖着沉积物的缓和的阶地，阶地的下段是一条很宽广的曳沙带，它几乎无疑是大陆块体遭侵蚀后冲入深水中物质形成的。

As one of the singular functions,step function plays an important role in the transient analysis of dynamic circuits and its definition is the key to analyze transient circuits.

1问题的提出如图1所示，阶跃函数是一种奇异函数，它在分析动态电路的过渡过程中具有重要的作用，而阶跃函数如何定义是正确应用它分析动态电路的关键。

For the singular spectrum analysis of time series, a method of constructing covariance matrix by using forth order cumulant is proposed. The method could restrain the Gaossian noise and symmetrical distributed noise mixed with chaotic signals.

对于时间序列的高阶奇异谱分析，提出了一种利用四阶累积量函数构造协方差矩阵的方法，该方法从理论上能有效地抑制叠加在混沌信号中的高斯噪声和对称分布噪声对重构结果的影响。

The equations of optimal probability density function of stochastic variable or limit state function are derived by use of the higher moments of the function.

一次二阶矩法主要利用随机变量的均值和方差信息以及分布概型来计算结构的失效概率，属于低阶矩法。

In chapter two, based on the property of uniform plane wave, field at boundary node is expressed with field in the computation region and expanded as Taylor's series. By truncating it at second order, a concise ABC is obtained.

首先，在第二章中，利用均匀平面波的特性，将边界节点上的场用计算区域内部的场表示，利用Taylor级数展开并截断到二阶，得出了一种形式十分简明的频域二阶吸收边界条件。

Recently,atoms with higher order vanishing moment were defined by Krant-z etc on some particular spaces of homogeneous type,but it hasn't been solvedthoroughly on usual spaces of homogeneous type.On the other hand,krantz'sstudy was made under the condition which the measure of the sets constructedby single element is zero,therefore their work didn't include the case of integ-er Z as a particular space of homogeneous type.Indeed,as a Hardy space on Z,〓(0＜p≤1)has been studied by some scholars.

尽管近来Krantz等人在某些齐型空间上定义了带高阶消失矩的原子，但在一般的齐型空间上建立带高阶消失矩的原子Hardy空间还没有完全解决，而且Krantz等人的工作是在单点集测度为零的条件下讨论的，因而不包括作为齐型空间的整数Z的情形。Z作为一类特殊的齐型空间，其上Hardy空间〓的问题有不少学者讨论过。

This paper only does research on adaptive blind source separation algorithm in two mixture models梚nstantaneous mixture and convolutive mixture.Blind source separation needs high order statistics.

盲分离算法需要用到高阶统计量，互累积量迫零法是一种直接利用高阶统计量的自适应盲分离算法。

Because the coefficient matrix of system equation with mixed method is indefinitive, an iterative solution method of the system equation is given out.

由于后者系数矩阵非正定，为使方程唯一可解，要求压力插值函数的阶必须低于固体相位移插值函数的阶，对此提出了一种系统方程的迭代求解方法。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.

交际能力和语法的关系应该是目标与途径的关系。
