Could fail. If the filesystem in question has data or media errors of some kind, mount mayreport it is unable to read the filesystem's superblock, which is (under Unix-like filesystems)filesystem as a whole. If you attempt to mount a CD-ROM or floppy drive, and there's no CDROM

如果文件系统有数据或媒体错误等问题的话，mount会报告不能读取文件系统超级块（UNIX类文件系统的下的），它是文件系统的一部分，大体上是用来为文件系统存储文件和属性信息的。

本文结合用户的要求和当前电力系统发展的需要，针对保定供电公司及其下属各工区、班组进行了系统设计，采用JSP+ Powerbuilder + Servlet + Visuar Basic + Wizcon + Sybase开发基于Web 方式的、跨平台的图形化综自、远动管理信息系统，采用现代化的手段进行综自、远动的定值管理、缺陷管理等，最后设计并实现了科学高效地管理综合自动化变电站和远动系统的大整个远动、综自系统。

So karst vegetation is charactered by Petrophile, Xerophile and Calciphihe in those areas where soil cover is very thin, and the underground drainage system is well developed. The running of karst ecosystem is controlled by two subsystems, which are karst dynamic system in inorganic life and genetic information transmitting system in organic life.

岩溶生态系统的运行受到两个子系统的联合作用驱动，即无机方面的"岩溶动力系统"和生命方面的"遗传信息传递系统"，但主要受以碳、水、钙循环为中心的岩溶动力系统的控制。

It describes mainly the process of systemdesign, including whole design, detail design, database design , security design, data structure and data code scheme, It introduces in detail how to create a graphic file of pipeline data on the MicroStation platform, and the exchange of data between the MicroStation and other GIS application software, At the same time, it introduces how to realize popular manage mode of GIS data on the MicroStation GeoGraphics, namely integratinggraphics and attribute.

本文在分析长沙市地下管线数据现状和目前数据管理情况的基础上，指出建立长沙市城市地下管网信息系统的必要性和紧迫性，阐述了系统的设计过程，包括总体设计、详细设计、数据库设计和安全设计，讲述了系统的数据组织方式及数据编码方案，并详细介绍在MicroStation平台下如何处理数据生成管网图形文件，阐述了系统实现的方法、过程以及与其它系统如何实现数据交换，也介绍在MicroStation GeoGraphics下如何实现当今GIS较为流行的数据管理模式：图属一体化。

A sort of image acquisition system of paper's number with CIS based on ARM and CPLD is introduced.A re-al-time approach is brought out to collecting high-speed image information and image pretreatment.This system is mainly designed of hardware,the collected CIS image signal is saved in the SDRAM(synchronous dynamic random access memory) through pretreatment of occulting output com-pensation,secondary filter,analog digital converter and binaryzation,getting ready for further image...

介绍了一种自行设计的基于 ARM 及 CPLD 技术，利用接触式图像传感器采集纸币号码的图像采集系统，提出了一种实时采集高速图像信息及图像预处理的方法；系统以硬件设计为主，采集到的 CIS 图像信号经过明暗输出补偿、二阶滤波、模数转换、二值化等前置调理，保存在同步动态内存中，供 ARM 作进一步图像处理；系统中 CIS 传感器的时序信号由 CPLD 设计，实验表明，采集到的二值化图像清晰；这项研究成果可以推广到证券、票据号码的录入系统以及其他相关领域的字符识别系统。

This paper researches under fund project of nationality natural science (70271045):"The researches on E-government system model and government affair flow reforger". It starts from the proper operation requirement of E-government system, combines the severe challenges of E-government system under current distributing environment, lucubrates the organization and authorization system model of complex government affair information system, presents the flow realization of security access control implementation of E-government system and some noticeable taches.

本文以国家自然科学基金项目(70271045)：&电子政务系统模型体系及政务流程再造研究&为研究背景，从电子政务系统特有的业务需求出发，结合当前分布式环境下的电子政务系统面临的严峻挑战，深入研究了复杂政务信息系统的组织与授权体系模型，给出了电子政务系统的安全访问控制实施过程中各个业务过程的流程实现以及需要注意的环节。

The design of technical architecture not only gives a topologic configuration in the complex system,but shows the relation between each component in the system.It plays an important role in designing,developing and implementing the whole system.

复杂信息系统的总体架构不仅定义了系统的组织结构和拓扑结构，并且显示了系统需求和构成系统元素之间的关系，是系统设计的核心工作、并对研发和实施具有重要的指导意义。

On the basis of introducing the channel and system model of wireless optical communication,average bit error rate of uncoded and RS coded system with channel side information were analyzed,and compared with Turbo coded system from the following two aspects:received optical power and Log-amplitude fluctuation variance.

在介绍无线光通信信道及系统模型的基础上，推导了无线光通信未编码系统和RS编码系统在已知信道边信息条件下的平均误码率，从接收光功率和对数振幅起伏方差方面对RS码编码系统和Turbo编码系统的性能进行比较。

In the second part, emphasis is put on the multiple capacity of orthogonal coded spread-spectrum multiple access system with coherent and noncoherent demodulations. The multiple access capacities of uncoded system and error -correcting coded system are compared. The capacity improvements which result from the use of diversity techniques are also studied.

第二部针对正交码扩频多址系统中多址容量的问题，分析比较了采用纠错码和不加纠错码时OC-SSMA系统的多址容量，并研究了分集技术的采用对OC-SSMA系统容量的提高，指出在信息速率及码片速率相同的条件下，正交码扩频系统的性能明显优于常规扩频系统。
