为有效发挥CATIA软件在有严格约束复杂曲面造型方面的计算快速、曲线精度高的优势，开发了基于宏命令的样条曲线自动生成程序，通过读入点坐标，利用程序生成CATIA的宏命令，然后利用CATIA软件在“创成式外形设计”环境下读入并运行宏命令，直接生成样条曲线。结果表明，此方法在处理由大量数据构成的曲面引导线时，可以有效提高工作效率并极大地降低数据出错的可能性。
To take advantage of high-fidelity, fast generation capability of CATIA software in generating curved surfaces, an auto-generation program of splines was developed based on macro command. The coordinates of discrete points are read in and then converted to CATScript. Then the macro script is read by CATIA in the“generative shape design”mod-ule, and the spline is generated. To employ this tool to deal with the guide curves of sur-face from massive data can increase the work efficiency and greatly decrease the data er-ror.

根据Unix系统中用户的历史命令序列，提出一种基于命令紧密度模型的用户伪装入侵检测方法。该方法从命令组合的角度抽取用户的行为模式。用户经常组合使用的命令，表现出关系紧密；不常被一起使用的命令，表现出关系疏远。通过滑动窗口方法从用户的历史命令序列中生成紧密度矩阵。如果待检测的命令块对于该用户来说表现出紧密度过低，则判断为异常。实验表明该方法计算量小，检测效果好，而且具有很高的实时性。
According to the history of command sequence in Unix system ,an approach to masquerader detection based on the closeness model of command was proposed .The behavior patterns of user were extracted from the view of command combinations . Those commands combined frequently by users showed close relationship ,and other commands exhibited loose relationship .Com-mand closeness matrix was generated by the sliding window from the sequence of commands .If the command block to be detected exhibited a low closeness for the user ,it was judged as abnormal .Experimental results show that a simple calculation ,an accurate detection ,and a high level of real-time can be achieved by using the proposed approach .

在通过计算机对设备、仪器进行远程控制的过程中，为提高操作的效率和准确性，减少误操作，提出了通过计算机软件集成控制的方式，将常用到的一组操作存储为一条批处理命令（脚本命令），直接调用脚本命令即可实现对一组命令的处理，而不必一步步的进行操作，也不必关心每一步的执行顺序。介绍了脚本命令的组成，存储方式及界面组成、在工程实践中验证了该方案的可靠性和实用性。
In the remote control of equipment and instrument by computer, in order to improve the operation efficiency and accuracy as well as reduce the incorrect operation, the integrated control method by using computer software is proposed. A group of commonly used operations are stored as a batch processing command (script command), the processing of a group of commands is implemented by directly calling the script command without a step- by- step operation and concerning about every step of the execution sequence. The composition of script command, the storage mode and the interfacial composition are introduced, and the reliability and the practicability of this scheme are verified in engineering practice.

行政抽象命令制定机关应关注其实施情况,在必要时予以修改,以适应经济、社会发展的需要.但事实上,由于制度缺位,制定机关对行政抽象命令出台后是否达到预期效果,缺乏足够的了解.而实行后评估,正好可以增加制定机关对行政抽象命令实施情况的了解,提高行政抽象命令的合法性与实效性,更好地保护行政相对人的合法权益.
The enacting body of the administrative abstract command should focus on its implementation , and modify it when necessary, to meet the demands of economic and social development .However, actually, the enacting body often lacks sufficient understanding of whether it has achieved the expected effects after the administrative abstract command is issued due to the lack of the relative systems.Therefore, the application of post -evaluation system will make the enacting body to know a-bout the implementation effect of the administrative abstract command , to improve the legality and effectiveness of the adminis-trative abstract command, and to protect the lawful rights and interests of the administrative counterpart .

从僵尸程序执行轨迹对二进制代码块的覆盖规律出发,提出了一种僵尸网络控制命令发掘方法。通过分析执行轨迹对代码块的覆盖率特征实现对僵尸网络控制命令空间的发掘,根据代码空间是否被全覆盖来验证发现的僵尸网络命令空间的全面性。对僵尸网络Zeus、SdBot、AgoBot的执行轨迹进行了代码块覆盖率分析,结果表明,该方法能够快速准确地发掘出僵尸网络的控制命令集合,时间和空间开销小,且该命令集合所对应的执行轨迹可以覆盖僵尸程序95%以上的代码空间。
There are some inherent patterns in the bot execution trace coverage of basic blocks. Using these patterns, an approach was proposed to infer Botnet command-and-control protocol (C&C protocol). Without intermediate representa-tion of binary code and constraints solving, this approach has a lower time and space overhead. This coverage analysis approach was evaluated on 3 famous Botnet:Zeus, Sdbot and Agobot. The result shows that this approach can accurately and efficiently extract the Botnet control commands. And the completeness of the extracted control commands could be veri-fied by checking whether all available basic blocks in bot are covered by the traces triggered by the control commands.

SAS被誉为国际上数据处理和统计分析领域的标准软件系统,但其程序编写复杂且难度较大,对使用者的要求较高。为了更好的使用SAS软件实现Meta分析,Stephen Senna等人编写了一套专用于二分类资料的Meta分析的宏命令。这套宏语言可以方便的实现Meta分析,绘制森林图、漏斗图、加尔布雷斯图、Q-Q正态分布图等图形。本文结合实例对应用SAS宏语言实现二分类数据Meta分析的方法进行详细介绍。
SAS system is considered as one of international standard software systems in the field of data processing and statistics, however, it required the user has higher capability due to its complex and difficult programming. For well applying SAS for conducting a Meta-analysis, Stephen Senna and his colleagues developed a suite of macros for the Meta-analysis of binary data. These macros will realize the Meta-analysis of binary data conveniently and can generate the forest plot, funnel plot, Galbraith plot, Q-Q plot and other graphs. The authors introduced in the paper how to use these SAS macros for conducting the Meta-analysis of binary data.

For monitoring the work states of optical remote sensor in real time and automatically alarming when the work states are abnormal, the power characteristic analysis method based on command sets of optical remote sensor was developed. By sampling and iterating the relationship between power and various command sets, the dynamic threshold function based on command sets was summarized. And the threshold function was optimized, since some actual conditions must be considered such as surge, command delay and so on. And the optimized threshold function was applied to the power monitor and control system. The system adopted 20 Hz sample frequency to monitor the power of optical remote sensor in the heat cycle experiment, which would last 12.5 days. The command refresh cycle was 512 ms of the optical remote sensor. The results show the method can exactly monitor states of optical sensor and alarm when the states are abnormal. That puts power alarm method of optical remote sensor into practice
