    与其他类型压敏器件相比,接触式电容压力传感器(TMCPS)有着明显的优点,例如较好的线性,高灵敏度和大过载保护能力等。为了达到更好的性能,设计了一种新型的接触式电容压力传感器(DTMCPS),这种新型的结构是在传统的TMCPS的底部电极上刻蚀了一个浅槽。与现有的接触式电容压力传感器相比,这种结构可以实现更好的线性和更大的线性范围。使用有限元分析软件对膜片的变形进行了分析并阐述了传感器的结构和工艺过程。分析结果表明这种新型结构的传感器可以在保持传统结构优点的同时实现更高的灵敏度,更好的线性和更大的线性范围。Touch mode capacitive pressure sensor(TMCPS) has distinct advantages over other pressure sensors.To achieve better characteristics,a new type of touch mode capacitive pressure sensor named DTMCPS was devised,which had an additional thin notch on the bottom electrode of traditional TMCPS.Compared to present touch mode capacitive pressure sensors,the new sensor is characterized by better linearity and large linear operation range.Finite element analysis(FEA) was employed to model the structural deformation of this device.After that,the structure and fabrication process of the sensor were given

    【中文文摘】使用514 5nm激光激发,第一次得到了不同形状金纳米粒子的表面增强拉曼光谱(SERS)。一般情况下,较短波长(600nm)的激发。然而,对特殊形状的自组装金纳米粒子,由于避雷针效应,即使使用绿光激发也可获得很高增强的SERS。 【英文文摘】In this communication, we obtained for the first time the SERS spectra of gold at the laser excitation of 514.5 nm by fabricating the ordered array of gold nanoparticles with special shapes, e.g., sphere, tadpole, and pearlchain. Selfassemble method of these gold nanoparticles is briefly introduced. In general, the enhancement of gold by the laser excitation of short wavelength (600 nm) becuase that the coupling between conduction electrons and interband electronic transitions by using 514. 5 nm depresses the quality of the surface plasmon resonance of gold metals considerably. Our observation reveals that the SERS of self2assembly gold nanoparticles with special shape can be rather high even using the green light excitation , which is mainly due to the lightning2rod effect.国家自然科学基金创新群体研究资助项目(20021002);; 国家自然科学基金九五重点项目(29833060

    溅蚀是土壤侵蚀过程的开始,为侵蚀发展提供了物质来源。因此,对其进行研究有助于对侵蚀过程的深入了解。本文选择了广泛分布于黄土高原地区的黄绵土,通过对不同粒径的土样进行模拟降雨试验,分析了土壤颗粒的溅蚀规律和表土结皮的形成过程,以及溅蚀率变化趋势。结果表明,不同粒径土样的溅蚀量差异明显,粒径在0.15mm附近的土壤颗粒最易被溅蚀;在一定的降雨历时内不同粒径土样的表土结皮发育完善程度不同,据此可以很好地解释溅蚀率的变化
