查询词典 vortex line

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。

And obtain an analogy result of Kazdan and Warner's, and then we use our theorem to study the vortex equation in Holomorphic line bundle over non-Kahler complex manifolds.

在第三部分我们考虑了一类Kazdan-Warner型的方程，并且证明了一个存在性的定理，借助于这一结果我们给出了一般的紧复流形M上的全纯线丛上的vortex方程解的存在性的一个充分性条件，或许这一考虑有其它方面的作用的。

With the deeping of the trough and the westward moving of the tropical cyclone, the low level vortex and wind shear line extended along a southwest - northeast orientation over the Yangtze River. On the effect of high, middle and low latitude systems, a rainband in southwest - northeast orientation formed gradually.

随着阻塞形势的发展和热带气旋的西移北上，经向环流加强，主要影响天气系统——低空的低涡切变线沿西南－东北方向伸展，在高、中、低纬度天气系统的共同作用下，一条西南－东北走向的雨带逐渐形成。

Based on NCEP and other observational datasets, a severe heavy rainfall process occurred in the south of china during June 18-19,1998 was investigated. The first diagnostic analyses show that the strong rainfall are produced by vortex, shear line and upper and lower jets, stationary front. The condition of high energy, saturation, potential instability is propitious to the form and maintenance of this rainfall.

采用NCEP全球谱模式和常规观测资料对98年6月18～19日华南暴雨的影响系统及其可能机制进行了初步诊断分析，发现这次强降水过程是受低槽、低涡、切变线、高、低空急流和地面静止锋共同影响造成的，该地区维持高能、饱和、潜在不稳定的环境，有利于暴雨的产生。

Compressing air expands in nozzle, and then enters into vortex tube in the tangent line direction.

工作时压缩气体在喷嘴内膨胀，然后以很高的速度沿切线方向进入涡流管。

Heavy rainfall occurred in the southeast of vortex and shear line.

暴雨发生在低涡切变线的东南侧。

Suppose that the vortex core line is slightly displaced relative to its initial completely straight con guration.

假设涡旋核心线相对原来笔直的线有一点位移。

The precipitation process was due to the meeting of the Huabei cold vortex and the shear line system along the Changjiang River.

分析了1999年5月17～18日，由华北冷涡与长江中、下游切变线系统在山东境内交汇形成的一次较强的降水过程。

X strong deceleration on the southwest flow occurred when the low vortex with shear line move to the sea.

3当切变线低涡离陆入海时，X矢量则对西南气流产生强烈的减速作用。

The result of numerical simulation by MM5 model shows that convection takes place on shear line, vortex and θe front .

中尺度数值模式(MM5)模拟结果表明强对流运动发生在对流层中低层切变线、气旋和南北向等θ_e，线密集带。
