Capacitive micromechanical ultrasonic transducers(CMUTs) have been widely studied because they can be used as substitutes for piezoelectric ultrasonic transducers in imaging applications. However, it is unclear whether and how CMUTs can be developed for sensors incorporating other functions. For instance, researchers have proposed the use of CMUTs for pressure sensing, but fundamental and practical application issues remain unsolved. This study explored ways in which a pressure sensor can be pro...  相似文献

Four intensive uplift periods, i.e., 60–35, 25–17 and 12–8 Ma (but 18–13 Ma in the Himalayas of the southern Tibet), and since about 5 Ma, can be determined on the Tibetan Plateau by synthetical analysis of low-temperature thermo-chronology data, sedimentary deposit records, and structural deformation records of different areas. The strong tectonic uplift periods in different areas on the Tibetan Plateau are penecontemporaneous, except for the Himalayan area of the southern Tibet, where a rapid uplift and e...  相似文献

UWB channel modeling for indoor line-of-sight environment   总被引:2,自引:0,他引:2  
SV/IEEE 802.15.3a model has been the standard model for Ultra-wide bandwidth (UWB) indoor non-line-of-sight (NLOS) wireless propagation,but for line-of-sight (LOS) case,it is not well defined. In this paper,a new statistical distribution model exclusively used for LOS environment is proposed based on investigation of the experimental data. By reducing the number of the visible random arriving clusters,the model itself and the parameters estimating of the corresponding model are simplified in comparison with SV/IEEE 802.15.3a model. The simulation result indicates that the proposed model is more accurate in modeling small-scale LOS environment than SV/IEEE 802.15.3a model when considering cumulative distribution functions (CDFs) for the three key channel impulse response (CIR) statistics.  相似文献

1 IntroductionDuring the last decade, the robust stability andstabilization problem for uncertain dynamic systemswith time delay have received much attention. Manyarticles focusing on time-delay systems have beenreported [1-4]. Delays frequently lead to instability andare sources of oscillations in many systems. For ex-ample, the trivial solution of the equationasymptotically stable, but thatof the equation for neutral systemunstable for any delayd > 0, so the study of the stability of neutral…  相似文献

Magnetic reconnection is a main process converting the magnetic energy into thermal and kinetic energy in plasmas. It is one of the fundamental problems of crucial importance not only to space plasmas physics and space weather studies,such as the solar flare,coronal mass ejections and magnetospheric substorms,but also to the stability analysis in magnetically confined fusion. In general,except for cases with periodical boundary conditions,three-dimensional(3D) magnetic re-connection occurs on magnetic separatrices generated by magnetic nulls. Here we briefly introduce/review the theories and some recent satellite observations of 3D magnetic reconnection. Topics to be further studied are also discussed.  相似文献

Design optimization of flow control device for multi-strand tundish   总被引:1,自引:0,他引:1  
The fluid flow phenomena in tundish have a strong influence not only on the uniform of composition and temperature of bath, but also on the separation of non-metallic inclusions, especially for the multi-strand tundish. A water model of a multi-strand tundish has been set up based on the Froude number and Reynold number similarity criteria. The effect of dam+weir and baffle on the uniform of composition and temperature of bath for different nozzles has been studied. The residence time distribution curves of the fluid flow were measured by SG800. Comparing the photos of the flow pattern in tundish, the optimum arrangement of baf-fle+dam was obtained. This new structure is benefit not only to uniform the temperature among different SENs (submerge entry nozzles) but also to separate the non-inclusions from the liquid steel, it can be widely used in multi-strand tundish.  相似文献

我国现行刑法中有关受贿罪内容与《联合国反腐公约》相比较有一定差距,而且司法实践中暴露出来的现行有关受贿罪立法的不足直接影响我国对受贿罪的打击力度,为推动我国刑法国际化和反腐斗争的深入开展,我国有关受贿罪立法的完善势在必行。研究了“为他人谋取利益”要件理论争执及其局限性。无论把“为他人谋取利益”作为受贿罪的客观要件还是主观要件,都存在不科学的地方,建议取消“为他人谋取利益”的规定。  相似文献

科学在本质上是与人文相通的,具有人文属性.一方面,科学是“人为的“,具有“人为“的属性,这表现在科学研究的活动及其结果的各个方面,其中科学探索的动机渗透着人的理想、信念、兴趣和激情等人的因素,科学研究的方法体现着人的想象、直觉、顿悟等非理性方法以及简单性、和谐性、对称性、守恒性等美学原则,科学活动的结果即科学知识及其体系中内涵着科学家和科学共同体的“范式“、“研究纲领“等人的认识原则以及概念、判断、推理等只有人才具有的理性框架.另一方面,科学又是“为人的“,具有“为人“的属性,这主要表现在科学是为了人的生存和实现人类自由而全面发展服务的,并且科学已经创造出了巨大的物质财富和精神成就,推进了人类物质文明的昌盛和精神文明的进步.  相似文献

马克思主义理论课教学效果不理想,原因主要是理论脱离实际,但要大规模地开展社会实践活动,在时间、组织、经费等方面都有一定困难。如注意点、线、面结合,则能缓解上述困难。所谓点,就是要抓住重点;线、就是各门课程内容要连线,并注意实践活动沿线考察;面,就是要抓好面上的实践教学。从实践的结果来看,这种点、线、面结合的方法是行之有效的。  相似文献

"经济人"一般被认为是有理性地追求自身利益最大化的市场活动主体,其"自利"的特性决定了"经济人"在客观事实上的伦理困惑,即经济行为与道德行为的二律背反性;然而,由于其面临的伦理冲突使其利益最大化的行为受到阻碍,"经济人"又不得不遵从道德的一些伦理规则。"经济人"的伦理困惑在一定程度上也说明了经济与伦理相联姻的必要性和现实性。  相似文献
