The invention provides a method for achieving priority level for generating sequence of mapping items which are transformed by network address, the method comprises the following method, first, when an address conversion apparatus needs to converse address after the address conversion apparatus receives a data packet, judging whether the items are generated, upwards sending the data packet to a CPU when a mapping item is not generated, step B, judging whether concurrent mapping number exceeds the preset mapping enqueue threshold with the CPU, if exceeds the preset mapping enqueue threshold, and judging whether a Referer field is contained in HTTP data, and recording the Referer field or a GET field according to judgment result, writing in a REF table, and arraying a priority level for each user according to a write sequence, and step C, leading the CPU to generate map in turn according to the priority level in the REF table, and then sending down to a forwarding layer to transfer a data packet.

本发明提供一种对网络地址转换的映射条目生成顺序实现优先级的方法，包括下列步骤：步骤A：当地址转换设备收到数据包后，需要进行地址转换时，判断映射条目是否已经生成，在未生成映射条目时，将数据包上送至CPU；步骤B：CPU判断并发映射数是否超过预定的映射入队门限，如果是，则判断在HTTP数据中是否含有Referer字段，并根据判断结果记录Referer字段或者GET字段，写入REF表中，并将每个用户依照写入顺序排列出优先级；步骤C：CPU依照REF表中的优先级依次生成映射，然后下发到转发层面转发数据包。

The paper describes basic working principles of SDH-5 type water-depth measurement instrument. Aiming at the time disagreement between water-depth data and position data,the big error in the reading of water-depth measurment data, low automation,large amount of work in homework data processing, etc.

本文描述了SDH－5型测深仪的基本工作原理，并针对国产SDH系列模拟式水深测量仪器存在水深数据与定位数据记录时间不一致、水深测量数据判读误差大、自动化程度低、内业数据处理工作量大等缺陷，介绍了作者应用单片机技术研制的SDH－5／CLZ－Ⅰ型水深数据采集、处理与串行发送装置。

The scheme for the data exchange platform among different data operation nodes under distributive isomeric data environment is discussed in the paper in order to satisfy the actual demands for the airport informatization. This data exchange platform forming integral design idea, system's logical structure and operation mechanism is elaborated.

文章从机场信息化的实际需求出发，论述了分布式异构数据环境下数据交换平台实现机场数据整合的构建方案，从整体架构设计、系统逻辑结构和工作机制三个方面对交换平台作了详述。

SQL Server offers less of a gain for binary data than for structured data, so your server farm might gain cost savings by using an external data store to contain your binary data files.

相对于结构化数据而言，SQL Server 为二进制数据提供了较少的支持，因此你的服务器场通过使用一个外部的数据存储包含你的二进制文件可以节省花费。

When DTD is available, XSLC can analyze the data model and encode elements according to the relationship of father node and son node, compress data part according to its type, and support query operations app-lied on compressed files, as for only one time of scanning data is needed, all the processes can be implemented in XML data stream environment.

提出XSLC（XML stream layered-coding compression）算法，通过预先扫描DTD对数据模式进行分析，继而根据元素的父子关系进行子元素层面的编码；同时根据数据类型进行数据压缩，能够在压缩之后的文档上进行查询，因为仅需一遍压缩扫描所以可以应用于数据流环境。

Although a mechanism that allow multi-user to edit the same data file can improve the data updating performance and promote the creating and cooperation of geographic data, the so-called version updating conflict problems that arise from the inconsistency of geographic data due to different editing behaviors must be considered beforehand.

一个允许多使用者同时更新同一地理资料档案的机制固然可提升资料更新的效率，并且促进地理资料的建置与分工，然而建置一个多使用者编辑之多版本地理资料库却也势必面临各种编辑者不同的编辑行为可能导致地理资料的不一致，而产生所谓的『版本更新冲突』。

When the floppy disc drive is not writing data to or reading data from the disc, data read from the disc is supplied sector by sector from the buffer memory to the system bus or data to be written to the disc is supplied sector by sector to the buffer memory from the system bus.

当软盘驱动器不是正在将数据写入盘或从盘读取数据时，从盘读取的数据逐个扇区地从缓冲存储器传输到系统总线或待写入盘的数据逐个扇区地从系统总线传输到缓冲存储器。

The image information storing means provides a vector data storing means which stores vector data of an original drawing, and a vector data projecting means which projects the vector data to four kinds of coordinate systems.

图象信息存储器提供存储原始绘图向量数据的向量数据存储器，和将向量数据投影到四种坐标系中的向量数据投影器。

Surface ozone data of Mauna Loa and the other 14 monitoring sites of altitude lower than 1000 m in the northern hemisphere were used to give a joint discussion for the distribution and variation features of surface O3. The data, based on ground observation, were collected, processed, and distributed by WDCGG (World Data Centre for Greenhouse Gases) in GAW. The monthly mean and hourly data of surface ozone in these 15 sites were analyzed to sum up the difference of surface ozone annual and seasonal variations in different areas of the northern hemisphere.

利用来自GAW（Global Atmosphere Watch，全球大气监测）的、由WDCGG World Data Centre for Greenhouse Gases，世界温室气体数据中心）收集整理和发布的、基于地基观测的北半球共15个站点的地面O3含量的逐月观测资料以及逐时观测资料，分析、对比并总结了北半球不同经纬度各区域的地面O3含量的年变化和各个季节的日变化规律。

The shaping method of noncircular part and the tool holder's radial motion characters in noncircular turning process are discussed in detail in the thesis.

论文详细研究了非圆零件的成型方法和加工过程中刀架的径向运动规律。

I have not really liked him,I do not like his this kind of disposition.
