涡旋

Consider a circular vortex ring of radius R.

考虑半径为R的涡旋环。

If the circumpolar vortex lasts longer than usual in future years, a large ozone hole could be expected to develop above the Arctic.

如果环极涡旋在未来几年里比正常情况下持续更长时间，一个大规模的臭氧空洞就很可能在北极上空发展起来。

Based on the analyses of the observation data and numerical model of ocean circulation, the variations of the Kuroshio in Luzon strait (included Bashi strait and Balintang strait) have been studied by using the theories of potential vorticity conservation and oceanic Rossby wave; It was first discovered that the climatologic mean state of the Kuroshio exhibits a westward bending through the Luzon strait. The location of the Kuroshio bending is limited to the east of 119E and frequently flanked by a cold eddy to southwest of the Kuroshio; This bending of the Kuroshio favors the formation of the anticycle eddy in the east of the Luzon strait.

依据对海洋观测资料的分析，运用位涡守恒，海洋Rossby波动理论和数值模式，研究了黑潮在吕宋海峡（包括巴士海峡和巴林塘海峡）的形变特征；首次确定了在吕宋海峡黑潮的形变的平均状态是黑潮向南海的弯曲，该弯曲西端位置一般不超过119E，该弯曲的西南侧常常出现冷涡；该弯曲有利于吕宋海峡东侧形成一个反气旋涡旋。

By mean of the method of upper and lower solutions, we will obtain a existence theorem like Kazdan-Warners. Using this theorem, we will study the vortex equation in holomorphic line bundle over complex manifold and prove a theorem of existence of Hermitian metric with a prescribed holomorphic section.

在本论文的最后部分，我们在紧复流形上讨论一类Kazdan-Warner型方程，用上下解方法得到了光滑解存在的Kazdan-Warner型定理，并将其用于研究全纯线丛的涡旋方程，得到了一个具有预定全纯截面的厄米度量的存在定理。

The effects of the structure constant of the refractive index fluctuations Cn2 and the inner scale of the turbulence l0 on the M2 factor have been analyzed quantitatively. Consequently, a new method for determining the characteristics parameters of the turbulence based on the measurement of the M2 factor by experiments has been proposed.

定量分析了表征大气湍流参数的折射率结构常数Cn2和涡旋内尺度l0对M2因子的影响，并由此提出了一种通过实验测量大气湍流中光束的M2因子，进而确定出大气湍流参数的新方法。

Moreover, the scroll compressor of the inspiratory duration is far longer than other types of compressors, and the gas inspiratory processing is the active and containable movement, which is different from other forms of passive suction compressor, or even to generate suction booster effect, so volumetric efficiency is particularly high.

再者，涡旋压缩机的吸气持续时间远远长于其他形式的压缩机，且其进气过程是主动的包容运动，这不同于其他形式压缩机的被动吸气，甚至还会产生吸气增压效应，故容积效率特别高。

The use of the world's largest compressor manufacturing company closed the entire United States COPLAND scroll compressor, high efficiency, noise, low energy consumption.

采用世界最大的压缩机制造公司美国COPLAND全封闭涡旋式压缩机，效率高，噪音小，能耗低。

This week, in Nature, Eugene Serabyn of the Jet Propulsion Laboratory in California and his colleagues describe a stunning implementation of what is known as an optical vortex coronagraph.

本周，加利福尼亚州喷气推进实验室的尤金·瑟拉宾和他的同事将在《自然》杂志中描述被称为光学涡旋日冕的一项惊人的实验。

Around the dark core of an optical vortex, the energy flow carried by the light beam is like a spiral staircase, flowing in a clockwise or counterclockwise direction.

绕着光涡旋的黑暗中心，光束携带的能量流就像螺旋梯，沿着顺时针或者逆时针方向流动。

Recently, the study of the critical state dynamics has achieved great advance based on the development of vortex dynamics.

然而近年来基于涡旋动力学理论的发展，逐步形成了临界态动力学研究课题。

As she looked at Warrington's manly face, and dark, melancholy eyes, she had settled in her mind that he must have been the victim of an unhappy attachment.

每逢看到沃林顿那刚毅的脸，那乌黑、忧郁的眼睛，她便会相信，他一定作过不幸的爱情的受害者。

Maybe they'll disappear into a pothole.

也许他们将在壶穴里消失
