查询词典 current coordinates

Based on the analysis of the affected extent of the neutral-point potential by every space vector on all kinds of voltage and current conditions the concept named neutral point control grade was proposed for the first time in this paper. The calculation formulas of NPCG were presented as well. Based on NPCG, a novel modulation scheme called optimized 3D space vector modulation (O3DSVM) scheme was proposed in a-b-0 coordinates based on the translation principle of axes, by which the space vectors with higher NPCG values are selected to synthesize the object vector to suppress the unbalance of the neutral-point potential.

该文通过对各种电流电压状态下每个三维空间矢量对直流中点电位的影响进行分析，提出了"中点控制度"(neutral-point control grades，NPCG)的概念，并给出了NPCG的计算公式；基于NPCG，在a-b-0坐标系下提出一种基于坐标平移原理的新型"三维矢量优化选择调制策略"(optimized 3D space vector modulation，O3DSVM)，该调制策略能优化选择NPCG值较高的矢量以合成目标矢量，从而达到最大程度控制直流中点电位偏移的目的。

Permanent Magnet Synchronous Motor driven by triphase sinusoidal current is studied object in this paper. The movement equtions in several coordinates are set up based on the analysis of electromagnetism restricted relation.

本文以三相正弦波驱动的永磁同步电机为研究对象，在深入分析其内在电磁约束关系的基础上，给出了不同坐标系下的运动方程，根据其数学模型，确定了电动车用电机在旋转坐标系下的矢量控制方案。

When aircraft approaching the airport,as long as camera can catch several existent installations and world-coordinates of which are known,current positions and attitudes of aircraft can be measured using projection relation by selecting corresponding point and line features.

当航空器飞行至机场附近时，只要机载单目摄像机能够拍摄到若干现有机场设施且已知这些点线特征的大地坐标，即可在图像上提取相应的点线特征，并依据投影关系测量计算出拍摄时刻航空器的位置和姿态参数。

To avoid jerky and ugly animations, we use linear interpolation between vertex coordinates of two consecutive frames (the current frame we are drawing and the next frame).

为了避免扭曲和丑陋的动画，我们在两个连续帧（当前我们正在绘制的帧和下一帧）的顶点坐标之间用线性插值。

Finally, we'll also want to get the logical coordinates of the mouse pointer, and we do this with the ElementToLogicalPoint API call, passing the current mouse position (which can be de-rived from the MouseEventArgs object that is passed to this function) and then loading the re-sults into the pLast variable.

最后，我们还需要获取到当前鼠标所在的逻辑坐标值，我们可以通过ElementToLogicalPoint方法来获取，传递当前鼠标的位置到该方法（鼠标的当前位置可以通过MouseEventArgs对象参数来获取），然后将返回结果保存到PLast变量中。

The sixth one came late at night and a telegraph operator did not notice that the coordinates mentioned were very close to the current ship's position.
