阶梯

Nevertheless, FDTD algorithm is implemented in rectangular mesh of Cartesian coordinates system. The curved boundaries must be approximated by staircases.

然而，FDTD算法是在直角坐标系的Yee网格下展开的，对弯曲界面只能用阶梯近似，从而带来很大误差。

建立了考虑节点中介性的结构优化模型，采用笔者提出的二阶梯度投影单纯形法求解。算例表明，具有节点中介状态的优化设计之煎量有增加的趋势，可见本文的思想对于避免设计偏于危险，使优化模型更趋合理是颇有意义的。

We use residual mean square instead of residual sum of square.

结果分段线性函数是比阶梯函数更广的函数类。

Besides the 30,000 frequently used phrases, there are 12 professional word-stocks are appended. The new function to construct phrases from taking the Characters from the screen and delete the phrases from the word-stock is convenient and agile. Also the Wangma Intellectual Pinyin Input Method is designed to the software. The unique Help and encoding prompt functions are added to the new software. The originated 'Retractile Antenna' Character sets switch method reduces identical codes greatly so as to improve the inputting speed greatly. The software adopts new simplified and traditional Character Roots list and originally creates the Three Grades to learn the Cross-codes that enables the beginners to learn the Method easily.

除系统自带的3万条常用词汇外，还特别设计了12种专业词库共10万条专业词汇，用户可以灵活选用；设计了屏幕取字造词功能，随造随用，灵活增删；增加了独特的"帮助"及编码提示功能；首创了"拉杆天线"式字集切换法，进一步减少了重码，使输入效率大为提高；推出了简繁兼备、配曲可唱的新字根表；安装了辅助的"王码智能拼音输入法"；独创了"识别码三段学习法"，为初学者由初级向高级过渡架设了阶梯。

Climbing a rope ladder requires more skill than climbing a rigid ladder, because the ladder tends to swing like a pendulum.

攀爬绳索，梯子，需要更多的技能，比攀爬梯子僵硬，因为阶梯趋于秋千就像一个钟摆一样。

Siggard stopped before the rough-hewn stairs to the wall and turned to face Sarnakyle.

Siggar 在通向城墙的粗糙阶梯前停下，转身面对 Sarnakyle 。

At the far end is another ladder, but before you go up, pull out your RPG.

在迄今结束是另一个阶梯，但在此之前去了，拉了你的RPG游戏。

The calculation of the rotordynamic coefficients of a multistepped annular seal in hydraulic turbines is discussed in this paper. Based on the Hirs' turbulence lubrication theory and the bulk flow model, the governing equations for the flow in the seal are developed by using the Moody's friction equations. The governing equations are perturbed when the rotor and the stator are coaxial. The Runge Kutta integration method and the Newton Raphson iteration method are used to solve the perturbation equations....

本文首先在Hirs紊流润滑理论的基础上，采用体积流动模型及Moody摩擦方程建立起阶梯口环水封中流体流动的控制方程，将各个方程在转子与定子同心处进行摄动，采用Runge－Kuta积分法及迭代过程求解摄动方程，建立起水轮机阶梯式口环水封的转子动力特性系数的计算方法，为水轮发电机组轴系的动力学分析提供了必要的理论基础。
