摘要：Energy consumed by distribution valves causes an energy loss for the output energy of hydraulic breakers, which has a significant influence on its efficiency. A new type of distribution valve used for hydraulic breakers, de- signed to reduce energy consumption, is analyzed on the basis of the operating principle and energy loss of the current distribution valve. The new distribution valve adopts a cone valve and the optimization technique of unequal open de- gree for the valve port. Theoretical calculations and analyses have proven that the new distribution valve can reduce en- ergy loss by 9.0127J, or energy consumption by 31%, during an impact cycle and the efficiency of the hydraulic breaker can be raised by 4.5%. It has the following characteristics: little leakage, little pressure loss and low energy consump- tion.

摘要：Based on the traditional optimization methods about the pressure control spring of the relief valve and combined with the advantages of neural network, this paper put forward the optimization method with many parameters and a lot of constraints based on neural network. The object function of optimization is transformed into the energy function of the neural network and the mathematical model of neural network optimization about the pressure control spring of the relief valve is set up in this method which also puts for ward its own algorithm. An example of application shows that network convergence gets stable state of minimization object function E, and object function converges to the utmost minimum point with steady function, then best solution is gained, which makes the design plan better. The algorithm of solution for the problem is effective about the optimum design of the pressure control spring and improves the performance target.

摘要：A design method of an intelligent temperature control system based on single-chip microcomputer is presented in this paper. The intelligent temperature control system is divided into four parts: monitor,heater,controlled process and feedback loop. Among them,the temperature detection circuit is designed with the conductivity of water by sensor detection. The optical coupler MOC3041 is used to implement the power control circuit,whose control object is 1 kW electric heater with the 220 V alternating current power; keyboard and display circuit SMC1602A include four buttons and LCD display to achieve human-computer interaction; Based on single-chip system STC89C52,the sensor signal and keyboard set target temperature are compared to the power automatically in order to finish the water temperature control. Through the static and dynamic data testing,the results show that the proposed method provides an effective way to realize the real-time acquisition and control of temperature.

摘要：The objective of this study was to investigate the mechanical characteristics of implant-abutment interface design in a dental implant system, using nonlinear finite element analysis （FEA） method. This finite element simulation study was applied on three commonly used commercial dental implant systems： model I, the reduced-diameter 3i implant system （West Palm Beach, FL, USA） with a hex and a 12-point double internal hexagonal connection; model II, the Semados implant system （Bego, Bremen, Germany） with combination of a conical （45° taper） and internal hexagonal connection; and model III, the Br,~nemark implant system （Nobel Biocare, Gothenburg, Sweden） with external hexagonal connection. In simulation, a force of 170 N with 45°oblique to the longitudinal axis of the implant was loaded to the top surface of the abutment. It has been found from the strength and stiffness analysis that the 3i implant system has the lowest maximum yon Mises stress, prirlcipal stress and displacement, while the Br^nemark implant system has the highest. It was concluded from our preliminary study using nonlinear FEA that the reduced-diameter 3i implant system with a hex and a 12-point double internal hexagonal connection had a better stress distribution, and produced a smaller displacement than the other two implant systems.

摘要：在微分代数学的框架的一个新奇适应差错容忍的控制计划为重电梯发射车辆(HLLV ) 的态度控制被建议。由使用完全数学的转变， HLLV 的 decoupled 输入产量代表被导出，显示三个 decoupled 秒顺序系统，即，沥青，偏航并且卷隧道。基于数字微分器的一种新类型，一个微分代数学的观察员(DAO ) 为估计系统状态和概括骚乱被建议，包括各种各样的骚乱和添加剂差错转矩。由 DAO 开车，有骚乱赔偿的三个改进 proportional-integral-differential (PID ) 控制器为沥青被设计，偏航并且卷控制。在靠近环的系统的信号一致地被保证最终是的所有由 Lyapunovs 间接方法的利用跳了。有说服力的数字模拟显示建议控制计划在面对参量的不安，外部骚乱，吵闹的贪污，和致动器差错完成高效是成功的。

摘要：耕作 trencher 的潜水艇的犁是主要功能的机制之一，并且它的优化是很重要的。设计参数在决定一个容器的拖引的力量的要求起一个很重要的作用。一个多客观的基因算法在获得犁的最佳的设计的努力基于犁表面的分析模型被检验了并且适用。为一个特定的土壤条件，草稿力量和是在犁的工作过程的关键参数的犁板表面区域被发现犁片穿入角度的相应最佳的价值和犁的主要的切片的二个表面角度优化。象偏差，犁板电梯角度，正切线的尖变化，和跨越的长度的犁板方面角度那样的参数也沿着土壤流动方向关于犁板表面的力量被分析。结果证明优化的犁有改进的犁表演。分别地，主要的切片和犁板的草稿力量是 10.6% 和 7% 不到原来的设计。犁板的 Gaussian 弯曲的标准差被 64.5% 降低，它暗示优化犁板表面的光滑比原版大得多。
