描述

It is important to the clarification of how to describe the state-space model during parameter perturbation and the standardization of the state-space model description.

这对澄清参数摄动时状态空间模型应该如何描述，进而规范状态空间模型的描述都是非常必要的。

To apply the method of Chapter Ⅱ to ring dynamics, we develop the streamline formalism to a canonical form in Chapter Ⅲ. The perturbation equations which describe the perturbed motion of streamlines are derived, with the general form of a near-conservative system.

为将上述映射方法应用到环动力学的研究，在第三章"流线表示法的正则描述"，我们研究该表示法的正则形式，导出描述流线运动的受振运动方程，该方程具有近保守系统的一般形式。

Its main features were: the flowering branch 70~170 cm; the inflorescence is racemes or simple panicle; the axis of inflorescence is thick, and the node is distict; there are 4~5 florets in a spikelet, and the spikelet is non-stem; small rachis internodes glabrous, and the pikelet like a stick; there are 2 membrane glume; the lemma is longer or equal to the palea; there are 2 squamas, and 6 stamens; its ovarium like ovatum; there are 3 brushy tigmas; did not see the caryopsis; flowering February-March.

摘要《中国植物志》第九卷第一分册及其它的相关文献均无关于竹亚科簕竹属吊罗坭竹花的描述或记录，本文作者采集制作了该竹子繁殖器官标本，并分别用中文和拉丁文对其进行了描述，其主要特征：花枝长70~170 cm；花序为总状花序或简单的圆锥花序；花序轴粗，节明显；小穗含4~5朵小花；小穗无柄；小穗轴节间无毛，呈棒状；颖2，膜质；外稃长或等于内稃；鳞被2；雄蕊6；子房卵形；柱头3，呈毛刷状；颖果未见。

Especially in recent years, international crude oil prices is rising and the ecological environment worsening crisis in a pincer attack from two, more and more people hoping for a "solar age" to arrive.

全文分三大部分。第一部分包括第一章，描述太阳能的利用和前景发展状况。第二部分包括第二章，描述太阳能系统组成及工作原理。

When described as a distance of an arc on the engagement pitch circle, it is called "Circumference Direction Backlash", when described as the shortest distance between two opposing tooth surfaces is called "Normal Line Backlash".

当描述为齿间弧度距离时，也叫做"圆周向回程间隙"。当描述为两啮合面的最短距离时，也称作"常规线性回程间隙"。

The beauty and pizazz of my loving snow is beyond any word of description in this world.

没有哪一种语言可以描述她的美丽，没有哪一种语言，可以描述她的潇洒。

Describing in no word could show its beauty as well as its pizazz.

没有哪一种语言可以描述她的美丽，没有哪一种语言，可以描述她的潇洒。

No word can describe her beauty and pizazz.

没有哪一种语言可以描述她的美丽，没有哪一种语言，可以描述她的潇洒。

Nothing can describe her beauty, nothing can speak out 用词不准 her pizazz.

没有哪一种语言可以描述她的美丽，没有哪一种语言，可以描述她的潇洒。

Because of its easily calculating and its accurately description parametric method has became mainstream in study field, polynomial hazard function distribution model was a large class of parametric models, when the dates are not readily handled by one of the common models such as exponential distribution or Weibull distribution, polynomial hazard function model always be used to provide adequate fits of the dates.

随着该学科的发展，大量参数、非参数方法相继提出，特别是生存分析的参数方法，以其处理简便、描述准确成为生存分析研究的主流方向。多项式危险函数模型是参数模型中的一大类，当一批数据不能用熟知的一些分布，诸如Weibull分布、对数正态分布进行很好的描述时，常常使用多项式危险函数模型。

It has been put forward that there exists single Ball point and double Ball points on the symmetrical connecting-rod curves of equilateral mechanisms.

从鲍尔点的形成原理出发，分析对称连杆曲线上鲍尔点的产生条件，提出等边机构的对称连杆曲线上有单鲍尔点和双鲍尔点。
