弦

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。

I think the people who flare with the right hand have a very good tremolo on the first string, and nothing on the second. We have to balance the guitar, we have many tunes that go across the string, so that's important.

我认为那些在一弦上可以演奏出非常精彩的轮指，而在二弦上则很糟糕的人，一定要设法在吉他上演奏出平衡的声音，这是非常重要的。

Flammer:The hammerheads are finished by high quality wool felt from Germany or Japan.We make the hammer core from selected fine wood like rosewood,zelkova and beech,which ensure consistency of the bright and beautiful tone of our piano.

弦槌：选用德国、日本制琴专用的呢绒，配以红木、黄檀木、榉木为槌心木栓来加工的弦槌，经久耐用，能保证音质过渡的统一连贯性，使音色更优美、柔和、明亮、有力。

My main research work is listed as follows: 1. Considering structure characteristics of high aspect ratio flexible wing, features of flat-straight-wing and backswept wing, the aeroelasticity of high aspect ratio of flexible wing, its structure model and aeroelastic dynamics equation of flexible wing have been studied.

Furthermore, in [3], Chen et al. proposed the mixed chordal ring network.

在文献[3]中，陈尚宽学长、黄光明老师、以及刘昱绮学姊又推广「有向的弦环式网路」来提出另一种有向的网路的连法，称为「混合的弦环式网路」。

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.
