绕成...

For long hair, try tying it into a ponytail and then loosely wrapping the tail around the fastening and pinning it into place to create a chic chignon.

对于长头发来说，试着把头发梳成马尾辫，然后把马尾松松地绕着发根盘成一个别致的发髻。

This technique uses a spiral phase plate with a small central aperture placed on the Fourier plane of so imaging system. If the spiral phase filter is rotated by a certain angle around its central axis, a phase shift between the zero-order spatial frequency component and the remaining of the object is produced, and the magnitude of this phase shift is proportional to the rotation angle. Using this property, we can record a sequence of intensity distribution of the output beams corresponding to different rotation angles, and then digitally reconstruct the objects by using a phase-shifting algorithm. Both the theoretical analysis and simulation experiment results demonstrate the feasibility of this approach.

在成像系统的频谱面上放置中心带有一通光孔径的螺旋相位板，在输出面上记录输入物体经螺旋相位滤波后的输出像；将螺旋相位滤波器绕轴旋转一定角度，通过中心光孔的零频成份与其他高频成份间会产生与旋转角度成正比的相移；利用这一特点，通过记录多幅对应不同旋转角度的输出光场强度分布图，然后再用一定的相移算法实现被记录物体相位分布的数字再现。

An ideal depolarizer can be combined with a λ/2 wave-plate and a λ/4 wave-plate rotating at different angular velocities with a certain ratio.

结果表明，让两波片以不同的角速度绕光线为轴旋转，当复合波片为一个λ/4波片和一个λ/2波片组合时，只要它们的角速度满足一定的比例时，可以组合成一个比较理想的退偏器；当复合波片为两个λ/4波片组合或为两个λ/2波片组合时，无论怎样旋转都不能组合成理想退偏器。

A Fourier transform infrared spectrophotometer, a solid state Si-NMR, a scanning electron microscope, an X-ray diffractometer, a thermogravimetric analyzer and a differential calorimeter were used to measure the structural and thermal properties of the WPU/silica hybrids.

研究中使用粒径分析仪、黏度仪与界面电位分析仪分析复合物乳液特性，利用傅立叶转换红外线光谱仪、固态核磁共振光谱仪、表面扫描电子显微镜、X-ray绕射光谱、热重量分析仪、示差扫描热卡计探讨混成复合物的结构、热性质与结晶情形，同时也利用万能拉力机、动态机械热分析仪探讨混成复合物的机械性质。

With perturbation shifting circumferentially step by step, the subsonic flows around slender bodies of revolution vary gradually in manner of single periodicity,while the supersonic flows vary gradually in manner of double periodicity.

由于临界周向位置的存在，随微小扰动沿周向逐渐移动，细长旋成体大攻角亚音速绕流呈现为"单周期、连续变化"规律，而超音速绕流则呈现为"双周期、连续变化"规律。

The trick is implementing the higher resolutions with you preferred graphic settings, by limiting your memory to just barely include the options you want, and then you force the resolution.

这个方法使你用你喜欢的显示设置实现了更高的分辨率，把你的显存设置成你在游戏中显示设置所需的水平，然后再强制分辨率（这里有点绕指的是在游戏里面用最低分辨率，然后设置其他选项设置完之后用-availablevidmem把显存设置成系统需求大小，然后在commandline.txt设置分辨率

For instance, a particle at the outer edge of Saturn's B ring is in a 2: 1 resonance with Mimas, meaning that it goes around the planet precisely twice for each lap the satellite completes.

例如，土星B环外缘的粒子与土卫一周期成2：1共振，意思是粒子每绕行星两圈，卫星刚好绕一圈。

The results of pressure drop characteristics experiments indicate that the new type cyclone tube's pressure drop reduction extent is directly related to the sticks'number, length and the radial position of the straight stick pressure drop reduction frame; is directly related to the length, width and number of grid pressure drop reduction frame installed under the split flow core tube.

安装在排气芯管内的直杆减阻框、栅格减阻框使旋风管的压降有不同程度的降低，减阻幅度与直杆减阻框杆数和长度成正比；与直杆的径向位置大小成反比；与安装位置、绕流截面形状有一定的关系；并与栅格减阻框的长度、宽度和片数成反比。
