析报告是在测试分析的基础上，对测试的结果以及测试的数据等加以记录和分析总结。它也是测试过程中的一个重要环节，同时，它也是对软件性能的一个总的分析和认可及对不足之处的说明。因此，测试分析报告对于今后对软件的功能的加强，不足之处的弥补等都起着十分重要的提纲作用。另外，它还有利于今后软件开发者阅读原程序，根据测试提供的数据和结果，分析原代码，掌握各函数的功能和局限性。从而缩短软件开发者的再开发时间和所耗费的精力．资金。-Analysis of the test report is based on the analysis of test results and test data to be recorded and analyzed and summarized. It is also in the process of testing an important part, at the same time, it is for software performance analysis and a general recognition and description of the inadequacies. Therefore, the test analysis report for the future of software is the strengthening of the inadequacies of the make up of the outline and so plays a very important role. In addition, it is also beneficial to the future software developers to read the original procedure, according to test data and results of analysis of the original code, to acquire all of the features and limitations of function. Software developers in order to shorten the re-development time and cost of energy. Fun

1、以DLL形式提供医生工作站 2、 根据【检查项目】，查询RIS系统中各工作站影像资料 3、 在选定【检查项目】后，根据【申请日期】、【检查状态】、【患者编号】和【患者姓名】等条件查询具体患者影像信息，患者影像信息包括患者基本信息（姓名、性别、住院号、检查部位等）、患者检查胶片和患者检查报告（包含历史报告）。 4、 对“患者检查胶片”进行编辑（调窗、放大、缩小、胶片翻转旋转、放大镜、滤镜、锐化、降燥、反色、测量等）-DLL form medical station, according to inspection items,query RIS system image data of each station , the selected inspection items, after the date of application under the,check the status. patients and the patient name,specific patient conditions, such as query image information, patient information, including images in patients with basic information (name, gender, hospital number, check the site, etc.), and patients were checked film inspection reports (including historical reports). 4, the "check the film were" edit (adjust window, zoom, flip the film rotate, magnifying glass, filter, sharpen, reduce dryness, anti-color, measurements, etc.)

哲学家进餐问题是荷兰学者Dijkstra 提出的经典问题之一,它是一个信号量机制问题的应用,在操作系统文化史上具有非常重要的地位。对该问题的剖析有助于学生深刻地理解计算机系统中的资源共享、进程同步、死锁等问题,并能熟练地应用信号量来解决生活中的控制流程,即将生活中的控制流程用形式化的方式表达出来。 假设有5个哲学家，他们花费一生中的时光思考和吃饭。这些哲学家共用一个圆桌，每个哲学家都有一把椅子。在桌子中央是一碗通心面，在桌子上放着5只筷子。（如图所示）当一个哲学家思考时，他与其他同事不交互。时而，哲学家会感到饥饿，并试图拿起与他相近的两只筷子（他与邻近左、右之间的筷子）。一个哲学家一次只能拿起一只筷子。显然，他不能从其他哲学家手里拿走筷子。当一个饥饿的哲学家同时有两只筷子时，他就不能不用释放他的筷子而自己吃了。当吃完后，他会放下两只筷子，并再次开始思考。 规定奇数号哲学家先拿他左边的筷子，然后再去拿右边的筷子；而偶数号哲学家则相反。按此规定，将是1、 2号哲学家竞争1号筷子；3、4号哲学家竞争3号筷子。即五位哲学家都先竞争奇数号筷子，获得后，再去竞争偶数号筷子，最后总会有一位哲学家能获得两只筷子而进餐。 -dining philosophers problem is the Netherlands scholars Dijkstra"s one of the classic, It is a signal to the mechanism of application, the operating system in the history of culture has a very important position. Analysis of the problem to help students understand deeply the computer system resource sharing, process synchronization, and other issues Deadlock, skilled and can be applied to solve the signal volume life of the control flow, about the life of the control flow wi
