Based on the boundary integral formula and natural boundary integral equation for the boundary value problems of biharmonic equation , the non-symmetrical banding solutions to the circular plate under thermal boundary conditions are gained by the Fourier series and convolution formulae.

根据双调和方程边值问题的边界积分公式和自然边界积分方程，利用傅立叶级数及卷积的几个公式，求得了相应变温边界条件下非对称载荷圆板的弯曲解，从实践上证明了此方法的可行性。

In the construction of the flood control projects, it is necessary to give attention to the ecological requirements by reasonably adopting the technologies of the ecological engineering in order to alleviate the negative effects from the hydraulic projects and avoid both the channelization and the discontinuities of the natural rivers.

在防洪工程建设中，需要兼顾生态需求，合理引入生态工程技术，减轻水利工程对河流生态系统的负面影响，避免自然河流的人工渠道化和非连续化。很多发达国家的堤防工程规范中已明确提出了这方面的要求，并发布了有关的技术导则或手册。

This method bases on distance transformation in Euclidean metric with the computational complexity of O(2+kn,and is the same with non-Euclidean metric space.

基于欧氏空间中离散点集的2阶V图距离变换原理，论述了栅格形式下离散点集和一般点集图形的2阶V图生成的方法，确定了它的时间复杂性为O(2+kn，适用于欧氏及非欧度量空间的自然图形2阶V图构造。

Among the Greeks, we have the school, or quasi-community of Pythagoras, whose object was to extirpate the passions, but it was philosophic rather than religious in its character and may be places in the category of Natural Asceticism.
