近几年来,包括我国在内的全球主要国家对钢材需用量同其国民经济产值有明显对应关系,钢材重新被确认为材料支柱。原因是经过高技术改造,钢铁工业发生了根本变化,推出了很多性能优越的“高技术钢材”,促进了相关工业的发展。微合金钢就是这些“高技术钢材”中用量最大的一种。在过去十年,我国针对大型露天矿重型设备、高压输送管线和制造运输集装箱需要发展微合金钢的经验表明,它是在高技术条件下生产的高经济效益钢材。展望21世纪,微合金钢由于有利于环境保护又有技术发展深度,在我国高压输气管线、造船和建筑钢结构方面还会有进一步发展。应列为创新项目,重点扶植、注意跟踪、及时开发,以带动钢铁工业技术改造。

This article summarizes our studies on micro flow sensors fabricated on a flexible polyimide circuit board by a low-cost hybrid process of thin-film deposition and circuit printing. The micro flow sensor has merits of flexibility, structural simplicity, easy integrability with circuits, and good sensing performance. The sensor, which adheres to an object surface, can detect the surface flow around the object. In our study, we install the fabricated micro flow sensors on micro aerial vehicles (MAVs) to detect the surface flow variation around the aircraft wing and deduce the aerodynamic parameters of the MAVs in flight. Wind tunnel experiments using the sensors integrated with the MAVs are also conducted.

To predict more precisely the frequency of force-balanced micro accelerometer with different bias voltages, the effects of bias voltages on error sensitivity of frequency is studied. The resonance frequency of accelerometer under closed loop control is derived according to its operation principle, and its error sensitivity is derived and analyzed under over etching structure according to the characteristics of Deep Reaction Ion Etching (DRIE). Based on the theoretical results, micro accelerometer is fabricated and tested to study the influences of AC bias voltage and DC bias voltage on sensitivity, respectively. Experimental results indicate that the relative errors between test data and theory data are less than 7%, and the fluctuating value of error sensitivity under the range of voltage adjustment is less than 0.01 μm . It is concluded that the error sensitivity with designed parameters of structure, circuit and process error can be used to predict the frequency of accelerometer with no need to consider the influence of bias voltage.
