Abstract : with the foundation of reliability principle on hydraulic parts, it brings forward how to enhance the inhere and applicable reliability about these parts . it is the key for quality of the equipment to realize the parts reliability 文摘:从液压元件可靠性设计的基本理论,提出了液压元件固有可靠性和使用可靠性设计途径,说明了液压元件的可靠性设计是提高液压设备可靠性的根本。
The products being manufactured not only boast such good performances that inhere to ordinary ceramic naterial as rust-resistant, unfading, cold-resistant, damp-proof etc ., but also possess wonderful luster gradual change effect and surface characteristics 其装修效果或稳重大气,或自然飘逸,或时尚摩登,或怀旧复古......将设计师的意念表现得淋漓尽致,能明显体现建筑物的文化品位,提高装修档次。
However, inhering limit from that in the layered and spinel structures, there is no continuous network of feo _ 6 edge-shared octahedral that might contribute to electronic conductivity, resulting in a extremely low electronic conductivity, which has been the greatest obstacle for application of lithium ion phosphate 然而由于晶体结构的固有限制,lifepo_4具有极低的电子导电率,这已成为限制其应用的最大障碍。
Migration community in transition will hold up to inhering their tradition, but cannot accept the action that their tradition mixes together with other tradition . migration can accept the simple and applied custom in " new hometown " . the second characteristic is variety and mobility 处于“过渡期”的移民社会,对移民保留自己“原有传统”持宽容态度,但对移民坚持“自己的传统”,拒绝与“他人的传统”进行协商的行为持否定态度。
For this interface unframed mode transparently transports the tdm frame without any attempt at interpreting the data, it seamlessly interfaces to all existing pbx equipment . this method is evolutionary rather than revolutionary, and it farthestly protects inhere investment . so it is an ideal complement to voip 与voip技术相比,本文的实现思路是一种渐进的非革命性,可以最大限度的保护在tdm设备上的原有投资,因此,它是对voip技术的一种有益的补充。
In order to study active vibration control with hydraulic servo deeply, the theory model of actual two-stage isolation mounting with hydraulic servo is set up . the force transfer rate of the system is deduced by the transfer function analytical method . the computer simulation of active vibration control performance is made for various control parameters and inhere parameters 为了深入研究液压伺服振动主动控制,针对实际柴油机液压伺服振动哈尔滨工程大学博士学位论文主动控制实验台架,建立了液压伺服振动主动控制系统模型,并进行了数字仿真研究,讨论了各种控制参数的引入对力传递率的影响,另外讨论了系统的固有参数的变化对力传递率的影响,为以后的液压伺服振动主动控制台架的改造和振动控制提供了有益的参考依据。
Nevertheless, due to the changes of social cultural environment, guidance from government, interposition of scholars, cultural persons and medias, the ceremony for promise fulfillment is changing from fete ceremony to amusing performance, and its inhere cultural connotation and symbol are being disappeared, which will result in the distortion of ethnic traditional culture 然而,由于社会文化环境的变化,政府的指导,学者、文化人和媒体的介入,还愿仪式正在发生变化,从祭祀仪式向娱乐性的表演演变,其故有的文化内涵和象征也正在消失,其结果将导致民族传统文化的失真。
Its main contents is as follow : firstly, it makes the discrete model for the subsystems of the scraper conveyor and the whole system with the finite element method; secondly, the modal analysis method is used to obtain the inhere frequency and mode of the viberation; finally, computer simulation is applied to get the displacement, velocity, acceleration and tension of the anyplace on the scraper conveyor for the four special working condition 其主要内容如下:用有限元方法建立了刮板输送机子系统及整个系统的离散体动力学模型;应用模态分析法求解系统的固有频率和振型;对四种非稳定工况下的动态特性进行计算机仿真,得出整个刮板输送机在任意点的位移、速度、加速度和动张力。
