Since there is natural different of the kinematic density formula for pairs of intersecting lines in two-dimensional surface and three-dimensional space, the inequalities for double chord-power integrals have studied from two side of two-dimensional surface and three-dimensional space using chord-power intergral inequality. Schwarz inequality. Holder inequality and so on.

They are particularly used in steel guitar and bottleneck guitar playing.

特别是在钢弦吉他及滑棒吉他上，经常都会用到这种调弦。

The aerodynamic characteristics of the cuted tip rhombus wing and double-delta wing of middling sweepback angle and aspect ratio about sixty type are investigated by a numerical method based on Eular equations.

采用Euler数值计算方法，对60多种中等后掠角及展弦比的切尖菱形机翼、双三角机翼纵向气动力特性进行了计算、分析和比较，从中筛选出16种切尖菱形机翼、14种双三角机翼进行了全机高速风洞实验研究，给出了机翼的展弦比、前缘后掠角、根梢比及几何扭转变化对全机升力、阻力及俯仰力矩的影响曲线和数据分析，在此基础上提出了用于定量估算两类机翼纵向气动力特性的关系式及修正因子。

Shows the end of Henan, Shaanxi Opera and after the introduction Puzhou Clapper, and local folk songs, made minor combination; one that transferred from the Northern Song direct the development of cable made of string; a folk concert in Henan is art, particularly since the Ming Dynasty later, in the Central Plains region based on the prevailing fashion Xiao Ling, absorbing "string rope" and other artistic achievement evolved.

一说明末秦腔与蒲州梆子传入河南后，与当地民歌、小调相结合而成；一说由北曲弦索调直接发展而成；一说是在河南民间演唱艺术，特别是自明朝中后期，在中原地区盛行的时尚小令基础上，吸收"弦索"等艺术成果发展而成。

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。

Three point registrations and ICP (Iterative Closest Point Algorithm) algorithm are used to register for multi-view data. The angle-and-chord's algorithm is advanced which is based on chordal deviation algorithm for data sampling. The method is proved to be effective and right by some examples.

采用基于参考点的对齐算法和ICP算法实现多视点云的对齐，在弦高差方法的基础上提出一种弦高角度法实现点云数据的精简处理，完成数据精简，实例应用表明所提方法精简效果好，数据的压缩效率高。
