涡旋

In chapter three,we have derived a generalized dual London equation for the Abelian "electric" field A_μfrom the effective dual Abelian-Higgs model.The approximative result and the numerical simulation result as well as their figs were shown via solving the dual Abelian-Higgs model with different methods.Hereby the vortex solution of the chromo-electric field and the vortex energy density were also discussed.Finally,we have studied the dual Abelian-Higgs model with additional vacuum constant,and have unpuzzled the vacuum constant corresponding to the bag model.When the quark sources is introduced, the vacuum constant in the MIT bag model is proportional to the quartic of the monopole mass.

利用不同方法求解该方程，给出了该方程的近似结果和数值模拟结果，并分别对两种情形画出图像作了比较，据此还讨论了色电场的涡旋解及能量密度，最后讨论了含有附加真空常数的对偶阿贝尔-黑格斯模型并对应口袋模型给出了附加真空常数的物理解释，引入夸克源之后还预言麻省口袋模型中的真空常数正比于单极质量的四次方。

It is within the updraft area, but with an upper-level anticyclone and downdraftover it.

这个中低层涡旋对应上升运动区，但它的上方是反气旋涡度，对应下沉运动。

There is a mesoscale anticyclone addy near Qingdao and Shidao.

在青岛石岛附近还存在一个中尺度的反气旋型涡旋。

According to the number of the current belt in the area, it is deduced that about 2 anticyclonic eddies, that is 2 clockwise sub-circulation systems, may occur every summer.

根据东、西向流带的数目推论，在该海域各年夏季可能存在2个反气旋涡旋，即呈现2个顺时针次级环流系统。

There may be anticyclonic eddies separating from the loop and then entering the SCS; 3 There is only the Kuroshio front, bending slightly to the SCS, and the Kuroshio does not directly enter the SCS.

目前国内外对该问题的研究有三种不同的观点：1黑潮以分支的形式深入南海；2黑潮以流套的形式进入南海，并有涡旋从黑潮主体中分离后进入南海；3在吕宋海峡处黑潮锋向南海弯曲，但没有明显的黑潮分支进入南海。

By the analysis of several gas forces in the twin-scroll compressor, the calculation formula of working volume and all different crank shaft angle are derived.

分析了双头涡旋齿涡旋盘所受的各种气体力，提出了在任意曲轴转角下的各种气体力及工作腔容积的计算公式。

Furthermore, the interference fringes of vortex beam are experimental investigated as well, it is found that the experimental observations are well consistent with the theoretical analysis.

对干涉条纹进行观察发现，实验观察结果和理论结果基本上保持一致，可以通过观察涡旋光束的干涉条纹来判断涡旋光束的轨道角动量。

To calculate the pressure drop of cyclone must consider the tangential velocity. Researchers regarded inner vortex as quasi-forced vortex and outer vortex as quasi-free one before.

旋风分离器阻力损失的理论计算离不开切向速度分布，以往在切向速度的研究中，认为内涡旋是准强制涡、外涡旋是准自由涡。

Taking advantage of potential vorticity thinking and vortex Rossby wave theory, we verify the existence of waves like VRW that is dynamical mechanism for intensity change.

利用位涡表征的螺旋雨带以及涡旋—Rossby波理论，探讨气旋加强与减弱的成因机理，证实了气旋环流中确实存在有涡旋—Rossby波性质的波动。

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
