By using Riemann-Schwarz's symmetry principle integrated with the analysis of singularity of complex potentials,the general solution of the problem is presented.

采用Riemann-Schwarz对称原理并结合复势函数奇性主部分析，得到该问题的一般解答。

In the composite-Boson field the topological structure of soliton is obtained with the Cauchy-Riemann condition. The evolution of soliton in such system is discussed in detail.

借助于Cauchy-Riemann条件揭示了复合玻色场中孤子态的拓扑结构，并详细考察了该系统中孤子态的演化。

In terms of the topological invariant in Riemann-Cartan spacetime proposed by Prof. Duan and the φ-mapping topological current theory, we gave the cosmic strings with the complex scalar field and showed that the strings appear in the zeroes of the scalar field. Meanwhile one can find that the length of cosmic strings is quantized in the topological level and the quantum number is determined by Hopf indices and Brouwer degrees.

以段一士教授提出的Riemann-Cartan流形中的新拓扑不变量为基础研究了宇宙弦的拓扑结构，指出宇宙弦只能存在于复标量场的零点处，而且在拓扑层面上是量子化的，而该量子数决定于Hopf指数和Brouwer度。

In this paper, two dimensional shallow flow—pollutants coupled model, which applies uninstructed grid finite volume method and Riemann approximate solver, is used to gain the trend of hydrodynamics and water quality change under the condition of driving force. Mechanism of nitrogen and phosphorous circle of WASP5 is considered in the water quality part of the model according to nutrition actuality of shallow lake in the cities.Xuanwu Lake is object of research in this paper.

本文针对城市浅水湖泊富营养化加剧现状，结合WASP5模型中有关氮和磷的循环机理，并将该机理写入已有的二维浅水流体水量模型中加以耦合，应用在无结构网格下的有限体积法与黎曼近似解求解的方法，求解湖泊在外驱动作用下的湖泊水动力和水质因子氮和磷的变化。

The obtained results indicate that in the case of Riemann-Liouville definition, theequivalence between FDEs and weak formulation does not require any initial conditions.

上述研究结果表明在Riemann-Liouville分数阶导数定义的情况下，分数阶扩散方程与弱形式的等价性证明不需要添加初值条件。

Wiles, and/or they, must also prove the Riemann Hypothisis!!!

怀尔斯，和／或他们，还必须证明黎曼假设！！！

He could not understand Riemann's work on Abelian functions nor Roch's contributions in his dissertation .

他不能理解Riemann在Abel函数方面的工作，也不懂Roch论文中的论著。

Similarly, some additional assumption is needed besides the Cauchy - Riemann equations, as the following example illustrates {{harv|Looman|1923|p=107

类似的有，有些在柯西-黎曼方程上额外的假定是必要的，下面的例子表明了这一点：{{harv|Looman|1923|p=107
