We have employed the binary system coding of ga directly to search and optimize the parameters of the control table under of the structure of fuzzy controller . the optimal and robust fuzzy controller which has overcome some shortcomings of traditional fuzzy controller has been designed 我们采用了遗传算法的二进制编码方式直接搜索系统空间，并优化控制查询表的参数，能生成具有很好控制特性的模糊控制器，克服了传统模糊控制器查询表参量固定不变的缺点。
The first kind of algorithm is based on s - box controlled by key , the algorithm distinguishes most of other block ciphers , its visible quality is that its s - box is not regular and fixative , but controlled by block cipher ' s key . the second kind of algorithm is based on smn ( d ) array code , it makes full use of the visible quality of smn ( d ) array code possessing big code distance ( d ) . the thesis discusses the two algorithms " reversibility , security and their qualities , the 第一种是基于“ s -盒由密钥控制”的变结构分组密码，该算法区别于其它大部分分组密码最大的特点是它的s -盒不是固定不变的而是由密钥控制产生；第二种是基于smn ( d )阵列编码的变结构分组密码，该算法充分利用了smn ( d )阵列编码具有码距大的特点；文中对这两个算法的可逆性、安全性及其性能等进行了探讨和分析，分析结果认为这两个变结构算法正确、有效且安全。
Based on above two points , developing electro - hydraulic proportional controller of having independent intellectual property is now urgent to civil auto crane manufacturer . at the beginning , in this thesis , a serial of models about auto crane ’ s function , construction and action are provided after being carefully analyzed with the modeling tool uml ( united modeling language ) . using these models , we can easily get along with the design and realization of electro - hydraulic proportional controller 本文首先从研究汽车起重机的功能入手,以面向对象的观点和使用uml作为建模工具,透彻地分析了汽车起重机功能应该具有的结构、行为特性,经过分析得出的结构、行为方面的特性是作为汽车起重机功能的内部描述存在的、具有固定不变的特点,这些特性的描述是研究与设计汽车起重机电液比例控制系统所必需的基础工作。
Patterns which are based on experience and experiment and wasteful in time , nonguarantecable in quality . high production efficiently is then achieved . and the same time , this paper puts forward a relative control system , changes and realizes the adjustment of spinning speed and the fixed increasing the technology and application of stone balls , yielding better economic efficienly . in the end of this paper , there is an appendix of computation program edited by c language , the geometry parameters of stone balls 同时通过恒定总流的能量方程和动量矩方程，确定了风水球转速的计算方法，建立了相应的控制系统，改变了过去风水球转速、转向固定不变的状况，实现了对转速转向的调节，设计了转向控制系统和转速控制系统，提高了风水球的技术含量和可观赏性，从而获得更好的经济效益。
In this paper , we stress the elements , the functional principles and influences of the power mechanism developing the county economy , provide the guidance for developing the different county economy which is not a constant mode . taken gaochun county as the example , study a county ’ s developmental strategy , typical developmental path and the principal measure , through which , the theoretical research has much more practical significance in this paper 为不同县域经济发展战略选择提供理论指南,而不是一个现成的固定不变的模式,并以高淳县为实例,研究制定了一个县域的发展战略、特色路径和主要措施,使本文理论研究更具有实践意义。
In rtbac , users execute permissions to access fixed data and tasks to access flowing and varying data such as documents being approving . rtbac can renew authorization in time according to the flowing and use of data in workflow systems . a formal description and an analysis of rtbac are given 并且在rtbac中：针对工作流的静态特性：固定不变的数据如已经归档的公文不能进行修改、制发等操作，一般只能查看，故与存取权限相关，用户通过执行相应的存取权限才能访问，即传统的rbac模型；针对工作流的动态特性：正在流动、不断变化的数据如正在接受审批的公文则与任务相关，任务可以对此数据进行某种方式的存取。
In chapter 5 , on the basis of the revised mimetic contagion model , we research in detail the relationship between herd behavior and speculative bubbles . we conclude that even if there are no interference from outside the market , it will fluctuate periodically as long as there is herd behavior whether the fundamental of the stock market is fixed or changes stochastically and the stronger the herd behavior , the more violently the price will fluctuate 首先利用模仿传染模型研究了从众行为与投机性泡沫的关系，结论是:股票市场在没有外界干扰的情况下，无论内在价值是固定不变的，还是随机变化的，只要存在从众行为，市场价格就会出现周期性的波动，而且市场上的从众行为程度越高，市场价格泡沫也就越大，风险也越高，越有可能危及金融安全。
In the traditional wavelet transform , because the wavelet filter and coefficient is fixed , as a result , when the discontinuous signal is analyzed , it will produce a lot of big wavelet coefficients in the transition , which makes against the compression . in the image processing , some image is roughness , and it may has sharp edges and oddity parts 由于传统小波变换的滤波器长度和系数是固定不变的,不能适应输入信号而变化,这使得在分析非连续信号时,在跃变点两侧会产生大的小波系数;对具有尖锐边缘、分段光滑或奇异点、图文混合图像处理效果很差。
The " relative " objectivism standpoint refers not to the fixed invariable objectivism standpoint , but the objectivism standpoint which changes along with the objective reality and changes through science criminal policy guidance ; while formulating the criminal law , the unification of the subject and the object tells us that the criminal law is the unification of crime facts and the legislator subjective will , therefore , the pure subjective will ’ s factors should be limited through all kinds of indirect or direct object factors , most basically , should be limited through the right procedure ; and we also should pay more attention to the reasonability and the validity of the pure fact factors 其中, “相对的”客观主义立场,并不是指固定不变的客观主义立场,而是随着客观现实的变化,通过科学的刑事政策的引导,而适时改变的客观主义立场;在刑法规范制定上,主客体统一表现为:刑法规范是犯罪的客观事实与立法者主观意志的统一。所以,在制定和运用刑法规范时,对于纯粹的主观意志的因素应当通过各种间接或直接的客体因素加以限制,其中最根本的是通过正当程序加以限制;对于纯粹的客观事实的因素应当注意其合理,合法性。
