不旋转的

The rubber flaps conceal the circuitry underneath; the keel on the bottom of the plug contains a housing for the metal points; and the half-turn to activate power to the plug removes the need for any switches.

胶皮将接线板的插槽紧紧盖住；插头底部的"龙骨状"结构可与插槽内的接触点相吻合；将插头顺时针旋转半圈就可以通电，因此开关装置就不必要了。

Hapgood ultimately revised key parts of his thinking because his calculations convinced him that the mass of the ice cap on Antartica could not destabilize the earth's rotation.

因为他的计算使他确信南极洲冰盖重量不能动摇地球的旋转，所以Hapgood最后修改了他想法的关键部份。

Experimental results on the trademark image database show that the extracted features can describe the image shape better,and have good invariant property under translation,scale and rotation.

实验结果表明，距离分布信息熵能有效地刻画出二值图象的形状特征，并且具有良好的平移、旋转及尺度不变性，检索结果符合人眼的视觉感受。

The result shows that the proposed indexing and matching algorithm performs well both in matching speed and in toleration of the non-linear deformation, besides its shift and rotation invariant property.

实验结果表明，本文提出的新的匹配算法除了具有平移、旋转不变性外，在匹配速度和容忍非线性形变方面具有良好的性能。

The kernel requarment for the rotating invariant property of a TFD based on fractional Fourier transform is proposed and proved in chapter 5. A close formula of Radon-Wigner transform of LFM signalis given. Based on the formula, the distribution of RWT is discussed.

第五章在首先简单介绍分数阶付立叶变换的基础上，提出并证明时—频分布具有旋转不变性对核函数的要求，给出了Radon-Wigner变换在直角坐标系下分布的一个显式公式，据此讨论了RWT分布特点。

The influence of inlet turbulence intensity on the velocity, temperature, turbulence kinetic, friction coefficient and Nusselt number is limited on a limited region which is smaller than 30d.

5旋转螺旋管道内的入口湍流强度对流动和温度场结构、湍动能、摩擦系数以及Nusselt数的影响都局限在距离入口端不超过30倍管道直径的有限长度内。

The watermark is embedded in the Complex Wavelet Domain of Relative Coordinates Line.

该方法利用了Dual Tree复数小波变换的优点，比如近似的平移、旋转不变性，完美重构等，将水印嵌入相对坐标线的复数小波域中。

Firstly,this paper analyses the operation in theory,it sets up the mathematical model of doubly fed induction generator two-phase rotating coordinate system according to the coordinate transformation theory.

本文以电压波动的工况为出发点，根据坐标变换理论建立了双馈异步发电机在两相旋转坐标系下的数学模型，同时考虑在电网电压不平衡扰动工况下，对此模型进行了进一步的修正。

However, a device driver need not provide the storage for an interrupt spin lock unless it has a multivector ISR or has more than one ISR, as described in Registering an ISR.

尽管这样，一个设备驱动不需要提供对中断旋转锁的存储除非它拥有一个多重的ISR或者它拥有超过一个ISR，跟在注册ISP中被描述的一样。

At the next stage, rather than repeating the search process with the same set of orthogonal vectors, as is done for the method of local variations, Rosenbrock rotates the set of directions to capture information about the objective ascertained during the course of the earlier moves.

在下一阶段，就不是像局部变量方法一样重复搜索同样集的正交向量了，Rosenbrock旋转了方向集来获得在早期移动过程中确定的目标的信息。

However, as the name（read－only memory）implies, CD disks cannot be written onorchanged in any way.

然而，正如其名字所指出的那样，CD盘不能写，也不能用任何方式改变其内容。
