The simulation results also find that the Quasi-Aitken weighted least squares estimator has a smaller asymptotic variance than least squares estimator.

研究结果显示机率加权最小平方法与Quasi-Aitken机率加权最小平方法的回归参数估计式皆具有不偏性，其中Quasi-Aitken机率加权最小平方法的回归参数估计式的变异最小。

Fourth,the number of nearest neighbor points is an important parameter for the local prediction method,which has an important impact on the prediction accuracy and computation complexity of the local model.

实验结果表明用该方法选取邻近点的局域线性预测方法和局域支持向量机预测方法的一步和多步预测性能较好，在满足预测精度较高的条件下，计算量较小。5。

A mathematic model is established and the performance of the technique is analyzed in this paper.

在此基础上，对传统的频率跟踪控制方法进行了性能分析，提出了一种通过可编程逻辑器件实现的逆变器频率跟踪全数字控制方法，建立了该控制方法的数学模型并对其进行了性能分析。

In comparison with the method in this paper and universal angle ruler,the maximum error in the method of it is +4′. The method of it is practicable and m...

同时，对测量方法与万能角度尺进行比较，得出使用方法的最大误差为+4′，证明方法是切实可行的，可以满足精密测量的要求。

This thesis mainly focuses on the convergence analysis of MCA neural networks with DDT method.

DDT方法的使用不需要DCT方法的严格条件，是一种更为合理的分析方法。

The simulation results indicate the method of comparison of the rationality and fairness.

最后通过算例将本文的方法与以往方法算得的分摊结果进行比较，充分说明了本文方法的合理性与公平性。

The difference of Runge-Kutta method, the method of multiple scales, the first method of interpolate perturbation, the.

分析了龙格库塔法、多尺度法、插值摄动第一法、插值摄动第二法等4种方法在计算一类非线性振动问题时的差异，给出了每一种方法对应的时程图和相位图，编写了每种方法的Matlab程序。

The studies of composition basically are the combination of two methods in terms of history. One is musicology, which is based on the analysis of the musical works. The other is history, which begins at the social environment in which the composer lived, and studies the impact of the social factors on the composer, further more, regards the impact as the basis of the analysis of the musical works.

历史上对音乐创作的研究基本上是两种方法的结合：一种是音乐学的方法，即以作品技术分析为中心的研究方法；一种是史学的方法，即从分析作曲家所处的社会环境入手，探讨各种社会因素对作曲家的影响，并以此作为对作品分析的基础。

A We simplified premise condition of the existing method , begin at an initial VG and propose a efficient algorithm. All VG developed are mutually disjoint.

a简化现存方法的前提条件（现存方法前提是全体VG或者全体IVG），仅从一个初始VG开始，中间过程避免了不交和的复杂运算，提出了快速有效的方法。

Meanwhile, the Hilbert transform mean mode decomposition was proposed to improve the computation speed and noise immunity.

针对局域波分解方法中的一些不足，提出了一种新的方法－希尔伯特变换均值模式分解法，提高了方法的计算速度和抗噪能力。

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。
