This thesis introduce the concept, character, and domestic and foreign circumstance of modern distance learning, analyze the possibility of developping distance learning, clarify the character and requirement of modern distance learning, after that using stream media technology to analyze the theory of technology, research the realization of stream media and the synchronization video courseware with teach planning and the encryptting method of stream file. At the end of this thesis, it research software and hardware system of distance learning, choose the phototype of the system, research system structure, flow and character.

本课题首先介绍了现代远程教育的概念、特点以及国内外现状，并对我国大力发展现代远程教育的可行性进行分析，明确现代远程教育的特点及需求，然后以流媒体为主要技术手段，分析技术原理，研究流式传输的技术实现、视频课件与教案的同步以及视频流文件的加密方法，最后对远程教育的软件、硬件平台进行研究，对系统进行选型，研究系统的结构、流程及特点，对使用到的MicrosoftWindowsMedia技术进行重点研究，然后提出流媒体的传送与播放的关键步骤，从而给出基于WindowsMediaService的远程教育系统，最后分析了基于流媒体技术的远程教育的特点。

In this paper, we researched and achieved in picture searching based on face recognition. We try to find out the pictures which and the given BMP picture are alike in faces.

摘要本文对基于人脸识别的图片检索系统进行了研究和实现，通过给定的BMP文件图片找到文件夹中与该图片中的人脸相似的图片。

Preoperatively and postoperatively computed tomographic scanning was performed in every patient. For the CAD treatment group, firstly, the 3D graph of the patient's skull was built based on the CT data using the reconstructing function of Mimics 8.11. Then the 3D file was imported to Geomagic 4.0. The injury lateral was resected and replaced by the mirror of the intact side, so an intact skull was generated at last. Consequently, a model was manufactured in a technical machine. The last step was to prebend the titanium mesh on the model.

CAD/CAM治疗组是利用术前诊断CT，将DICOM格式CT数据输入图像处理软件Mimics8.11，由软件生成颅颌面骨STL格式的三维图像文件，应用另一个图像处理软件Geomagic4.0读取该文件，并应用镜像工具以中线为轴线生成健侧半的镜像，最终得到双侧对称的颅颌面模型，将该图像信息输入快速成型系统，通过逐层树脂堆积，生成树脂头模。

In the design of SMCOS, introduce the software and hardware developing platform of SMCOS at first, then describe the system characteristic and hierarchical structure, tell the course of design and implementation of the software system of the SMCOS finally, mainly tell software architecture, design method to command interpreter, transmission module and file management, especially carry on deep explanation and discussion to the security environmental management of SMCOS, design the secure pseudorandom number generator according to systemic characteristic; Implement AES cryptographic algorithm, and optimize in term of the characteristics of AVR platform, make it reach the faster speed of encryption in case

在SMCOS的设计中，首先介绍了SMCOS的软硬件开发平台，然后描述了系统特性及其层次结构，最后讲述了SMCOS的软件系统设计与实现过程，主要讲述了SMCOS的软件架构、命令解释器、传输模块以及文件管理器的设计方法，特别对于SMCOS的安全环境管理进行深入的讲解及探讨，针对系统特点设计了安全的伪随机数生成方法；实现了AES加密服务模块，并针对AVR平台的特点进行了优化，使其在占用较小的代码空间的情况下达到较快的加密速度；改进了PIN的认证方法，对其传输过程提供了安全保护并采用了安全的验证方式以避免可能遭受的攻击：设计了相互认证命令，缩减了认证过程的时间消耗并提高了安全性。

Automatic production detailed list: Provides or closes two kind of conditions to choose for you; When designated when this condition for pass, needs to carry on the operation according to user to the MP3 document, presses "the option" in the broadcast detailed list, the system in provides above four functions except the change broadcast detailed list function outside, but also provides increases, move and completely delete the function; When designated this condition for opens time, so long as the execution renewal broadcast detailed list function, in the memory music document completely includes in the broadcast detailed list

自动生成清单：提供开或关两种状态供您选择；当选定该状态为关时，根据用户自己需要对MP3文件进行操作，在播放清单中按"选项"，系统在提供以上四项功能除更改播放清单功能之外，还提供新增、移除和全部移除功能；当选定该状态为开时，只要执行更新播放清单功能，存储器中的音乐文件全部列入播放清单中；·外观：提供三种播音机外观供您选择；·重复：您可指定关、单曲、全部方式中的一种；·随机：您可选择随机播放的开、关状态
