The stability problem leads to an ordinary differen-tial equation containing three parameters representing partialderivatives of a phase function.

一个非定常流动的稳定性问题被归结为求解三个未知函数为参数的微分方程的特征值，其三个参数分别是非线性扰动波的相函数的导数及圆盘运动速度的函数。

By using a similarity transformation, the Navier-Stobes equations in the cylindrical co-ordinates for the steady incompressible flow are reduced to an ordinary non-linear differential equation of the third order.

利用相似转换，将不可压缩流体，定常运动，柱坐标形式的纳非尔-斯托克司方程组简化为一三次非线性常微分方程，运用小参数法及适当边界条件求出此方程的解，结果表明，吸吮或吹注对流动的速度分布，沿流程压力下降和摩擦系数均有显著影响，其影响的大小，依赖于吸吮或吹注的性质，程度及二圆管的相对尺度。

However, almost all the current theories for climate prediction, including the ones in statistics and nonlinear science, are based on assumption that the process is stationary which is contrary to the nature of the climate process.

在大气运动中，气候正是一个典型的非平稳系统，但是现有的气候预测理论，包括统计预测理论和非线性预测理论，几乎都无一例外地建立在平稳性假定的基础之上，这有悖于气候过程的基本性质，因此它有可能是导致气候预测水平低下的重要的理论原因。

The algorithm tracks the changing rate of each coordinate transformation parameter through Kalman filter to facilitate better prediction of the initial searching point. More importantly, the powers of the noise models of the Kalman filter are effectively estimated online rather than making artificial assumptions on their values. The algorithm can hence adapt to various target motions and searching precisions in a real-time manner without any manual intervention.

该算法通过对坐标变换参数的变化率进行Kalman滤波来更好地预测初始搜索点；更重要的是，该算法有效地在线估计Kalman滤波器中的模型噪声功率，而非先验地对它们的取值做出假设，因而能够在没有任何人工干预的情况下动态地根据不同的目标运动状况和搜索精度进行实时调整。

The author performed a multi-elemental analysis on the cycle of competition state formation, asymmetry between competition state and competition performance, adjustability of competition state at competition field, and competition state evaluation indexes, and pointed out that competition state is a process of dynamic development, having characteristics of uncertainness.

对竞技状态形成的周期性、与运动成绩的非对称性、临场可调性以及评价指标的多元性进行分析，指出竞技状态是一个动态发展的过程，具有不确定性的特征。

Motion control of nonholonomic mobile robot is one of the most challengeable problems in robotics.

非完整移动机器人的运动控制是机器人学中最具有挑战性的问题之一，对这一问题的理论研究是广泛而又深入的，但是缺少比较成熟的实验结果。

Motion control of nonholonomic mobile robot is one of the most challengeable problems in robotics. The theoretic research of the problem is widely and deeply, but it is lack of well-rounded experiment results.

非完整移动机器人的运动控制是机器人学中最具有挑战性的问题之一，对这一问题的理论研究是广泛而又深入的，但是缺少比较成熟的实验结果。

The most frequent mechanism was commissural MR, or MR that originated at the site of successful commissurotomy, which occurred in 27 of 47 patients (57%), whereas noncommissural MR occurred in 20 (43%) patients, 12 (26%) with subalular damage resulting in chordae rupture and flail motion and 8 (17%) with leaflet laceration.

最常见的机制是联合部瓣膜返流或成功的瓣膜分离术术后原分离处的返流，47例患者中有27 例出现以上情况(57%)，而其余的发生非联合处的二尖瓣返流的20例(43%)患者中，12例伴有瓣膜下损害的患者出现腱索断裂和连伽运动，8例患者出现瓣叶撕裂。

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。
