A widely used method for checking real-time systems is,according to the real-time property to be checked,to use a proper bi-simulation equivalence relation to convert the infinite-timed state space to a finite equivalence class space.

一个被广泛用于验证实时系统的方法是根据被验证的实时性质，使用适当的双向模拟等价关系使无限的状态空间转化为有限的状态等价类空间。

Everybody is whooping, time fast passing, Huang Qu senior official yellow Jinlong is wanting anxiously measured this kind of steam corrosiveness actually how, actually can'tfind the material in the bare planetoid surface which any may test, the returns control center, collects each material to come back to be able to waste the massive precious time, therefore then without hesitation stretches out own left hand,"thick outer space clothing glove which wears with the left hand, may probe the outer space exposure suit whether can resist this kind of unknown corrosion, if does not have the question, we might attack boldly!"

正在大家议论纷纷的时候，时间正在快速的流逝，黄区长官黄金龙急切地想测测这种蒸汽的腐蚀性究竟如何，在光秃秃的小行星表面却找不到任何可以测试的材料，返回指挥中心，收集各种材料回来就会浪费大量宝贵的时间，于是便毫不犹豫地伸出自己的左手，"用左手戴着的厚实太空服手套，就可以试探一下太空防护服是否能够抵御这种未知的腐蚀，如果没有问题，我们就可以大胆进攻了！"

Yuan Zhesheng's fiction often recounts family and father-son stories. His most celebrated feature is his speculation on time. Imaginative games in enclosed space also turn up frequently in his writings. Therefore, a research framework consists of time, space and human world is a criterion that delineates a fictionist's image of mind in three-dimensions.

袁哲生写得最多的是家庭、父子小说，最为文坛知悉的是时间的思索，最常出现的场景是闭锁空间的游戏想像，因此时间、空间、人间三向轴的研究架构，是为立体化小说家创作心象所设的凖的。

On the base of upper studies, epidemiology and space-time distribution of HAPI were analyzed, the risk assessing frame of HPAI were established, the space-time model of air temperature which influenced the transmission of HPAI virus were analyzed and constructed, Bio-Math model for immunity and prevalence of avian influenza were establish.

在此基础上，对禽流感发生的流行病学分析，对高致病性禽流感时空分布规律的初步研究，从而初步建立了高致病禽流感传播的风险评估框架，分析并构建了温度对我国禽流感传播影响的时空模式，建立了禽流感免疫与流行的生物数学模型初析。

All of the programs implemented, the Canton City metropolitan area within the scope of 13 key areas, the transport hub of 21 points, 58 passenger distribution point can be incorporated into the net 30 minutes of time and space circle, Nansha, Shunde, Foshan, Nanhai, Dongguan and other places can also be incorporated into the 1 hour time-space circle.

Then, we discuss a robust implementation of the pilot-symbol-aided estimator that is insensive to channel statistics. The analysis of these algorithms is made by computer simulation. Finally, combinating with the application of channel estimation , we present two techniques: STBC (space-time block coding) and STTC (space-time trellis coding) to improve the performance of channel parameter estimation.

在基于导频的估计中，研究了基于MMSE下二维导频辅助信道估计，并结合无线信道的统计特性在一般不可知的条件下，给出了一种对无线信道的统计特性不是很敏感的鲁棒的二维导频辅助信道估计器，通过实验仿真证明其有效性。

Adopting generalized Jordan block and algebra equivalence transform method, all of the transfer functions at different load points can be transformed to state-space description with time variable. The steady robustness of three different mode of control systems were researched by mathematic analysis. It shows that: for the high order inertia controlled object with the characteristic of nonlinear and time-variable that described by the set of transfer functions, the Luenberger function observer established according to its any algebra equivalence state-space description, if some conditions can be met, there would be a matrix of T with n′n satisfied the Sylvester matrix equation TA- FT=GC.
