Through creating a good, relaxed classroom atmosphere, enhance the ability of students to the psychological conditioning to make it in the process of vocal learning to relax, open to singing, in order to achieve a better purpose of vocal lessons.

并通过制造一个良好、轻松的课堂气氛，提高学生心理调节能力，使其在学习声乐的过程中放松、通畅地歌唱，以达到上好一堂声乐课的目的。

Three kinds of different stamping technique for forming valve plate part of automotive air conditioner compressor were analyzed.

For more serious tinkering, the on-site pilot plant has a 150,000-square-foot, two-floor manufacturing operation in addition to a process lab that keeps more than 3,000 different ingredients on hand.

对于较严重的修修补补，现场试验工厂有150000平方英尺，两层制造业务除了实验室的过程，让超过3000个不同成分的手。

Wire electrode based on the trajectory of the different forms of control, WEDM can be divided into three types: one is shaped by the imitation controlled cutting in line in advance and work to create the same shape by mold, when processing the workpiece at the same time rough and on the mold clamping in the machine tool table, in the process of cutting wire electrode tightly against the mold on the edge of the track for the mobile, thus cutting out and die on the same shape and precision to the workpiece; another One is the electro-optical tracking control, to carry out the cutting line, before the basis of certain parts to enlarge the proportion of drawings depicts an electro-optical tracking map-processing machines will be placed in design stage of electro-optical tracking, tracking platform Photoelectric first line of graphics has always been to follow the track of the Mexican campaign, and then through the use of electrical, mechanical linkage to control the machine tool table, together with the workpiece so相似形wire electrode relative movement, thus cutting out the same shape and design to the workpiece; again a digital control, the use of advanced automatic control of digital technology-driven machine tool in accordance with the pre-processing parameters according to the workpiece geometry pre-processing procedures for the preparation of a good CNC auto-complete processing, the production does not require appearance on board the need to map to enlarge map of the previous two form of control has a higher machining accuracy and a broad range of applications, both at home and abroad more than 95% have adopted WEDM NC.

根据对电极丝运动轨迹的控制形式不同，电火花线切割机床又可分为三种：一种是靠模仿形控制，其在进行线切割加工前，预先制造出与工件形状相同的靠模，加工时把工件毛坯和靠模同时装夹在机床工作台上，在切割过程中电极丝紧紧地贴着靠模边缘作轨迹移动，从而切割出与靠模形状和精度相同的工件来；另一种是光电跟踪控制，其在进行线切割加工前，先根据零件图样按一定放大比例描绘出一张光电跟踪图，加工时将图样置于机床的光电跟踪台上，跟踪台上的光电头始终追随墨线图形的轨迹运动，再借助于电气、机械的联动，控制机床工作台连同工件相对电极丝做相似形的运动，从而切割出与图样形状相同的工件来；再一种是数字程序控制，采用先进的数字化自动控制技术，驱动机床按照加工前根据工件几何形状参数预先编制好的数控加工程序自动完成加工，不需要制作靠模样板也无需绘制放大图，比前面两种控制形式具有更高的加工精度和广阔的应用范围，目前国内外95%以上的电火花线切割机床都已采用数控化。切割属电加工范畴，是由前苏联人发明的，我国是第一个用于工业生产的国家，当时由复但大学和苏州长风机械厂合作生产的这是最早的机型叫复旦型，我们国内在此基础上发展了快走丝系统。欧美和日本发展了慢走系统LS

As a result, a weak indirect cell is formed in high latitudes. By the 36th time step, the model atmosphere accomplishes the transition form one-cell circulation to two-cell circulation. There is a momentum source in the upper subtropical region. During the transition, the"polar westerlies jet"gets weakened and vanishes at the end, while the subtropical westerlies jet gets strengthened. At this two-cell stage, the generation and dissipation of westerly angular momentum do not balance each other, and the atmosphere is still at an unstable state with great surplus of angular momentum generation.

随着模式的运行，直接环流加强，地表东风带制造西风角动量加大，上支气流的加强，同样在科氏力的作用下，在副热带地区形成副热带西风急流，同时所谓的&极地西风激流&向赤道靠拢、减弱，最后消失，这时在整个半球形成了靠赤道的直接环流和靠极地一侧的间接环流，两圈环流形成的过程仅仅需要9个小时左右。

Editor: Taiwan ' s stone businessmen have more money, richer international trade and production experience. That ' s why in the later development the Taiwan ' s stone enterprises in mainland reduce at quantity and scale? Do you think it has something to do with Taiwan ' s traders only utilizing the manufacture advantage of the mainland but leaving China mainland this important market aside?

编者：台湾石商有着较为雄厚的资本、丰富的国际贸易和生产经验，但是在后来的发展过程中，台湾在大陆的石材企业无论在数量和规模上都在相对减少，这是否与大部分台商是以出口市场为主，仅仅利用了大陆的制造优势，而忽略了大陆也是全球重要的市场的因素有关？
