上弦

For the sake of obtaining the force analytic results of strings, the deformation compatibility condition of strings and the middle rod are determined in this paper with the method of Hook's law.

在利用虎克定律确定了弦丝和中间细杆变形协调条件的基础上，得到了弦丝的受力分析结果。

This article takes the teaching of conic sections as an example. By designing worksheets, teachers can introduce the historical material about conic sections to students. By way of using Apollonius' definition of parabola, ellipse and hyperbola, teachers can introduce the geometric aspect of "conic section" to students. By using the concept of " latus rectum " in Conics , we can connect "conic sections"-- representation of geometrical aspect, with "the equation of conic sections"-- representation of algebraic aspect to improving insufficiency of text books.

同时本文也试著从历史文本中寻找材料，简单举例说明数学教师可以如何应用这些史料在几何单元教学上，例如三角函数的正余弦定理，最后再以圆锥曲线的正焦弦为例，说明如何利用数学史料於此单元的教学，尤其是阿波罗尼斯的《锥线论》中对圆锥曲线的3个命题，将此3个命题的内容与意涵，尤其是正焦弦在圆锥曲线的几何意义上所扮演的角色，将其适当地融入教学中，将可使学生真正学习圆锥曲线的几何知识，而不再只是代数形式的几何知识。

Nowadays, many guitarists sound fantastic on the third string, so it's possible to go across to it when perhaps before, in Segovia's times, he would prefer to move up the fourth.

现在，许多演奏家都可以在3弦上演奏出非常精彩的，但是在以前可能就不是这样，在Segovia的年代，他就愿意把有些乐句在第4弦上演奏。

Results In static phantom studies, the percent error of mean activity obtained by Carson's method was reduced to about 9 %, and it is less than that of image-derived method using maximum likelihood expectation maximization (about 14 %). In simulated dynamic phantom studies, the vessel component could be extracted using ICA in image and sinogram domain. In sinogram domain, the six components extracted by ICA could be obtained quickly.

在静态物理假体实验结果来看，使用Carson's method计算出感兴趣区域活性的百分比误差( 9%)比直接从影像取得活性的百分比误差( 14%)来得小；从数位模拟动态假体实验结果来看，独立成份分析法运用在影像空间或是弦波图空间上，都可以将血管分离出来，但从弦波图空间上得到各个独立成份相对於影像空间就快得多；imageICA和sinogramICA计算出的输入函数的标准化均方根误差分别是0.57和0.28。

He asserted that the most common shortcoming of most classical guitars were weak trebles, especially the G string, and the characteristic reticence of the notes played on the tenth, eleventh and twelfth frets of the first string.

他坚称在古典吉他上最常见的缺点是高音较弱，特别是在G弦，和弹第一弦十、十一和十二琴格上的音时，常出现典型的沉默寡言。

The shrinkages in tangential and longitudinal directions were negatively and positively,respectively,correlated with GS/GSI,while no clear relation was found between radial shrinkage and GS/GSI.

无论是正常木还是应拉木，在组织和宏观水平上(分别基于切片和实木上的观测)，弦向的干缩率都明显高于径向的，弦向和轴向干缩率分别与GS/GSI呈显著的负相关和正相关，而径向干缩率则与GS/GSI之间没有发现明显相关关系。

Use your 3rd finger to stop this string.

请注意，当你抱住Ukulele时，第一弦在下面，而图上的第一弦是在上面的。

And Pharaoh spoke to Joseph, saying, Your father and your brothers have come to you.

47：5 法老对约瑟说，你父亲和你弟兄们到你这里来了。

Additionally, the approximate flattening of surface strip using lines linking midpoints on perpendicular lines between geodesic curves and the unconditional extreme value method are discussed.

提出了用测地线方程、曲面上两点间短程线来计算膜结构曲面测地线的方法，同时，采用测地线间垂线的中点连线和用无约束极值法进行空间条状曲面近似展开的分析。
