In static design of the control system, the influences of three-axle unintersect, unverticality and disturbance moment to the simulator's position accuracy is analyzed, and the error analytic formula is suggested. The influence of system static and dynamical friction moment, distinguishability of D/A convertor to the low-speed characteristic of the simulator is also analyzed.

在控制系统的静态设计过程中，分析了三轴转台的三轴不相交度、三轴不垂直度和干扰力矩等对转台位置精度的影响，并求出了误差的解析表达式，分析了系统的静、动摩擦力矩、D／A转换器的分辨率等对转台低速特性的影响。

By proving the simulator-based and comparison-based definitions of semantic security both equivalent to the indistinguishability we obtain the equivalence of the two definitions. This conflicts with the conclusion of Watanabe, et al. The reason lies in that in the simulation-based definition they used, the adversary and its simulator are allowed to choose by themselves the auxiliary partial information about the plaintext to be input, which results in that the information chosen by them can be different.

该结论与Watanabe等人的结论相悖，原因在于他们采用的基于模拟器的语义安全性定义中允许敌手及其模拟器自己选择其输入的有关明文的附加部分信息，导致敌手模拟器与敌手选择的可能不同，使得该定义不等价于不可区分性，与公认的结论不符。

Because of the nonuniqueness in the positional solution, it's not easy to test the performance of the coordinated control system. So the model of NN was built to convert the vector of the length of 6 jars into the vector of the position of the motion deck. It's fast and accurate for the lengthwise direction. The state space system model of the six degree freedom motion simulator was built by the equations of electrodraulic servo mechanism and the multi-body dynamics equation of the six degree freedom motion simulator,the vector of the length of 6 jars was the control variable.

The geology research of carbonate reservoirs in Ordovician of Tahe oilfield showed that many large dissolved vugs and fractures were developed. The spread of the reservoir take on a very heterogeneous state. And the typical fractured-vuggy reservoirs was formed. According to the combination of the various spaces, the formation was divided into vuggy formation, fractured-vuggy formation and fractured formation. The research showed that development of the vug is relevant to the its position on the structure, the fractures, the water surface and the weathering surface. Multi-phase charge and recharge of the oil in the reservoirs resulted in the complexity of the fluid distribution. So the"Bottle Model"was brought forward to explain the movement of the water-oil contact. The special storage space and the complex fluid distribution lead to the unstability of the production and the complexity of the water cut. In order to explain the characteristic of the fracture-vug unit was brought forward and the basic principle and method of the partition of the fracture-vug unit was formed. The classification and evaluation of the units were performed according the reserve and energy. Based on the research of geology characteristic and the fluid flow in the reservoir the comprehensive numerical simulation plan of the fractured-vuggy reservoirs were established. Through the selection of the simulation unit, fluid flow type and parameter equivalent the triple media reservoir simulation model was established. Considering the practical application the model was resolved by the DKR decomposition conjugate grads method. Based on the fine reservoir description of Dsitrict IV of the Tahe oilfield the various space type were classified and combined together. The geology model of Unit S48 was constructed. Two typical single well model was established according to the geology and the dynamic phenomena. Finally the single well model and the Unit S48 were simulated by the triple media reservoir simulator. Via the local grid refinement and coarsening in the simulation good matchs were gained. Based on the results of the simulation the reserve distribution, percent of reserve produced in various space and the natural energy were analyzed. The fluid was storaged in the fractures and vugs mostly and more than 90% the produced oil came from the systems. The energy belonged to the active one. The results of simulation accorded with the fact and showed the validity and practicability the research and the simulator.

Ankle Foot Orthosis is usually applied for stroke patients to prevent foot drop during swing phase, and provides some range of ankle dorsiflexion after mid stance phase on walking. These conditions cause cyclic tensile and compression force on the AFO, and result in breaking or tearing of AFO after several weeks or months usage. Therefore, it is important for therapists to know what geometric modification of AFO can prolong its usage. The purpose of this study was to develop a motion simulator for observing the effect of simulated heel strike impact and foot dorsiflexion on the AFO. The geometry of motion simulator was designed similar to human leg.
