For further development, Yvan plans reimplementing some parts with code that he feels is unsatisfactory, as well as introducing local folders and thread support.

在将来的开发中， Yvan 将重新实作一些他认为不满意的部分的代码，同时也将引入本地文件夹和线程支持。

The first-order and second-order Raman scatterings of the silicon nanowires were studied in a temperature range from 123 K to 633 K.

在123K到633K范围内研究了纳米硅线Raman光谱的温度依赖关系，应用热效应非简谐过程，声子限域模型和晶格扩展效应分析研究结果；引入光子－电子－声子Raman散射过程解释了声学声子模峰强与光学声子模峰强的比值的温度依赖关系。

Based on analyzing the algorithms of Delaunay triangulation creation in domestic and abroad, in view of the situation of building DTM and the need of realizing railway 3D visual design, a divide-and-conquer algorithm to build DTM is presented, the algorithm use square grids to manage disordered points, to form triangular meshes in grids, DTM can be obtained by merging the triangular meshes, so that the work of sorting of the disordered points before building DTM is reduced greatly; moreover, the algorithm utilize subarea to control the vertices of convex hull so that the range which support points locate in can be predefined when searching support points, the workload of searching support points can be reduced and the speed of merging two triangulations is raised.

在分析了国内外构建DTM算法的基础上，针对DTM算法的现状及铁路线路三维可视化设计的需要，创立了一种构建DTM的分治算法。算法引入方格网管理离散点数据，在格中构建三角网，然后再将这些三角网合并形成DTM，极大地减少了构网前对所有参加构网的离散点进行排序的工作量。此外，通过对凸包顶点数据进行分区管理，在搜寻凸包支撑线时，能预先确定出支撑点的范围，减少了搜索工作量，提高了三角网的合并速度。

One way this might be done is to place a grid of wires behind them and induce a magnetic field where the wires cross.

有一种也许可行的方法，就是在其后放置一线网，在叉线处引入磁场。

In the negative and interrogative forms, of course, this is identical to the non-emphatic forms.

。但是，在否定句或疑问句里，这种带有"do"的方法表达的效果却没有什么强调的意思。
