Ship virtual reality design is the application of virtual reality techniques in ship design, realizing two stratifications of virtuality. The first is making possible for the ship owner, designers, shipyard and ship classification society to participate in ship design steps to pre-experience the performance of production. Second, it can put the emphasis on manufacture system and carry out effective analysis on its feasibility.

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

Through those atlases, we can study the space and time distribution characteristic of cities in the different spatial criterion, dynamically analyzing the process of the city growth, gather and the proliferation, carry on the analysis and the research to the city space and time variation process, and promulgate rule which the city expands to provide the policy-making basis for the urban planning and development.

通过这些图谱能够在不同的空间尺度上研究城市的时空分布特征，动态分析城市的生长、集聚与扩散的过程，对城市的时空演变过程进行分析和研究，揭示城市扩展的规律，为城市规划、城市发展提供决策依据。

The emulsion quartz stone material protective agent's solute has certain active multi-compositions and so on of functionality siloxanes and fluorine silicon hydride, this kind groups with the active ingredient carry alcoholysis reaction the ion condition water on quartz stone material surface, thus causes the siloxanes and the fluorine siloxanes has chemistry keying connection with the quartz stone surface, from outside to inside of the quartz stone surface and stone inside pore surface forms a kind of complex network structure, this kind of network structure is extremely dense, it may filter polar and carbon dioxide, slows down the speed that water molecules go in and out the quartz stone pore, so the quartz stone will not be soaked by the water molecules, meanwhile to be a barrier to stop alkaline compounds and salt to infiltrate from an interface to another, also can have the very good physical enhancement effect.

乳液型石材防护剂的溶质是具有一定活性的多官能度的硅氧烷和氟硅烷等组成，这种带有活性成份的基团与石材表层离子态水进行醇解反应，从而使硅氧烷和氟硅氧烷与石材表面进行化学键连接，由外向内在石材表面和石材内部毛的表层形成一种结构复杂的网状结构，此种网状结构极其密实，它可将极性水分子和二氧化碳进行过滤，减缓水分子进出石材毛孔的速度，不会被水分子浸湿，同时还有阻隔石材不同界面的碱性化合物和盐份向另外一个界面渗透，同时还能起到很好的物理增强效果。

Based on the time-frequency analysis (continuous wavelet transform and short time Fourier transform), the arithmetic uses the modulus maximum characteristic on the phase scale and carry frequency scale to recognize phase modulation rule of signal. So without whole wavelet coefficient the signal mathematics model can be obtained quickly. It provides well condition for application of arithmetic in practice.

该算法基于信号的时频分析（小波分析和短时傅里叶变换），利用小波变换的相位尺度和载波尺度的模极大值特征辨识信号的相位调制规律，因而在无需计算全部小波系数的情况下，可快速地获得信号的数学模型，为算法在实际中的应用提供了良好的条件。

It can carry on the measurement of various kinds of oceanography key elements and geophysics parameters, photography, sea the floor of sea, take a geology sample salvage the ore in the depth in the ocean and maintain and repair underwater regular industrial facility through the equipment, investigation.

借助这些装备可以进行各种海洋学要素和地球物理学参量的测量、海底的考察和摄影、海底铺设电缆、地质取样及打捞蕴藏在大洋深处的矿石、水下固定工业设施的使用维护和修理等。
