查询词典 in rotation

The specificity of the surface gained in this way is that when the beam of rays parallel to its axis of rotation falls on it, the beam is reflected so that all the rays meet in one point, known as the focus, in the same way that optical lenses focus light rays in their focus.

抛物线的表面或曰抛物面，是由抛物线围绕其对称轴旋转而成，其特点是，和抛物线对称轴平行的射线波束被抛物面所反射，所有的电波都在同一点汇聚， 1 September，2009 3D 角反射天线作馈源的 5.8GHz 偏馈抛物面天线我们把这点叫做焦点。

We found that in the case of neglecting magnetic shear, the plasma current also can be driven by the shear Alfvén wave and the circularly polarized wave, respectively, the efficiency of current drive in the rotation plasma is independent of the plasma density In addition, it is found that whether m=0 or m≠ 0, the effect of the magnetic shear on the compressional Alfvén wave current drive makes the efficiency be dependent on the plasma density and inversely proportional to it.

当考虑旋转效应而不考虑磁剪切效应时，等离子体平板模型下平面极化压缩阿尔芬波能够驱动旋转等离子体电流，驱动效率也与等离子体密度无关，却与旋转大小成正比，这与Avinash[Phys Plasmas 4，2204（1997）]的结论一致。我们发现在这种情况下剪切阿尔芬波和圆偏振阿尔芬波都可以驱动旋转等离子体电流，旋转效应引起的电流驱动与密度无关。

Motion synchronization between tool in X direction and principal axis rotation was controlled by electronic gearbox in cam turning. And profiling mechanism could be superseded by servo tool-holder. Linear motor direct drive servo tool-holder was designed, and host-slave control system with PC and DSP was developed for the require of high-speed and realtime servo. The technical process was analyzed in cam turning. Servo tool holder with tool swinging and principal axis variable rotate speed were presented to keep constant cutting angle and speed.

将电子齿轮箱用于凸轮车削加工系统的传动，以伺服刀架取代了传统加工的靠模装置，实现了刀具X方向直线运动与机床主轴转动的同步控制；设计了直线电机直接驱动的伺服刀架及基于PC与DSP构成的上—下位机控制结构，采用DSP进行实时控制以满足高速伺服需要；对凸轮加工过程的工艺特点与恒角度、恒速度车削进行研究，提出了具有刀具摆动功能的伺服刀架与机床主轴变转速运动方案。

In group 2, except 3 patients (2 in groups 2a, 1 in group 2b) who had morderate limitation of forearm rotation need further management, both pronation and supination could be restored to more than 80. As a result, 37 wrists (92.5%) of 36 patients were satisfied with the operation.

前臂旋转的回复，除了group 2a中的2位因有中等程度的内转限制均为77外，其余group2各组的内、外转皆可达到80以上，而36例37手腕（92.5%）的手术，都能令病人得到满意的结果。

In the present study changes in neuronal activity during and after adaptation to prolonged optic flow stimulation (translation, radiation and rotation) were investigated by extracellular single-unit recording in area PMLS of the cat.

本文采用胞外记录法研究了猫PMLS区神经元在长时程光流刺激时及刺激后细胞反应的变化。

A concept named"Characteristic rotating vector"of images is brought forward in this dissertation, the rotation of target in the image is only represented by change in sequence of elements in the vector, thus disturbance brought by irregular edge of target and random noise is avoided.

提出了图像的特征旋转矢量的概念，当图像中的目标有旋转时，仅表现为向量元素次序的变化，避免了不规则的目标边缘及随机噪声带来的干扰。
