查询词典 homogeneous coordinates

It is shown that in Jameson's algorithm is not an orthogonal stream-lines coordinate system, but a local stream-lines coordinate system instead. Nevetheless, because of the finite-difference discretization in Jameson's scheme is not carried out along the direction of s and n, but along the Cartesian coordinates, the analysis on all terms of the full potential equation in Cartesian coordinates reveals that his scheme does take a back-ward difference along the streamwise exactly at all points in the supersonic flow region.

表明其所采用的坐标系不是真正的正交流线坐标系，而是局部流线坐标系；同时由于Jameson方法并不对s，n进行差分离散，而是在原笛卡尔坐标系下作差分离散，对笛卡尔坐标系下的全位势方程中的各项的分析表明，Jameson方法恰好能做到在超音速点沿真正的流线方向作后差分。

According to the limited space the end of all surface sampling points in 3D space within the Cartesian coordinates, then be converted into computer on the screen coordinates of the pixel, thus drawn with a real sense of three-dimensional images.

根据有限空间中底面上所有采样点在三维笛卡儿空间内的坐标，然后将其转换为计算机屏幕上的像素点的坐标，从而绘制出具有真实立体感的图像。

If singular value curve is convex in the coordinates 'k' of maximum peak of curvature spectrum, then the number of effective singular values is k; if singular value curve is concave in the coordinates 'k', then the number of effective singular values is k-1, and this rule is tested by the signal processing examples.

如果奇异值曲线在曲率谱最大峰值的位置坐标k处是凸出的，则有效奇异值的个数为k；如果奇异值曲线在k处是凹进的，则有效奇异值的个数为k-1，通过信号处理实例证实了这种结论。

MiniGUI provides two functions to realize the conversion between device coordinates and logical coordinates.

MiniGUI 提供了两个函数来进行设备坐标和逻辑坐标的转换。

"Of or relating to the coordinate system, or to any of three coordinates in it, formed by two polar coordinates in a plane and a rectangular coordinate measured perpendicularly from the plane."

"坐标系的，或者与坐标系有关的，或坐标产生三条坐柱中的任一个的，这个坐标系由一个平面上的两个极线坐标和一个平面上垂直测量的直角坐标形成。"

The formulae were derived to calculate the spherical coordinates of any vector after the specimen was rotated any angles around any axis based on the homogenous coordinate theory. An example was put forward to show how to use the formulae to calculate the spherical coordinates of the crystal in the synchrotron radiation topographic analysis.

If it is FALSE, the coordinates are offsets to the current window-corner coordinates.

如果为False，则坐标为到窗口边角坐标的偏移。

The method gets the current shape position coordinates and the desired coordinates.

该方法获取当前形状的位置坐标和所需的坐标。

Current coordinates of the robot cleaner are aligned with reference coordinates of the recharging station, and the robot cleaner moves to a previous spot where it was before it returns to the recharging station, and resumes the work from where it stopped.

机器人清洁器的当前坐标以充电站的参考坐标被校准，而机器人清洁器移动到它返回充电站前所在的先前地点，并从停止处继续给定的工作。

Next, you want to zoom around the current mouse coordinates, which is very simple to do by just converting the mouse coordinates to a logical point using the ElementToLogicalPoint me- thod of the MultiScaleImage control.

接下来你还希望能够围绕鼠标坐标进行缩放，这也非常简单。

Liapunov—Schmidt method is one of the most important method in the bifurcation theory.
