基于PEM和模糊PI的反应磁控溅射非线性控制方法

反应溅射存在不稳定性,需要对反应溅射过程进行非线性控制。分析了迟滞效应的不稳定特性,提出了基于PEM的非线性动态平衡控制法。以镀CrN膜为研究对象,靶原子光谱相对强度为反馈参数,用ATmega16设计了反应气体的PEM控制系统,分析了压电阀的控制特性。以PI和模糊PI为非线性控制方法,按照镀膜工艺要求在四靶磁控溅射镀膜机上进行控制试验。结果表明,压电阀非线性特性严重,需作为系统反馈参数;模糊PI方法较PI方法优,能实现反应溅射过程的动态实时稳定,控制误差为±2.5%。基片的镀膜厚度和耐磨性满足使用要求,验证了模糊PI法在反应溅射控制工程应用的正确性,为发展高性能的硬质薄膜材料奠定了基础。     

水泥土应变软化特性三轴试验研究

目前,水泥土在工程当中已得到广泛运用.为了深入了解其力学性质,在大量三轴试验的基础上,对水泥土的破坏模式、应变软化相关特性进行了研究.试验结果表明:水泥土的破坏模式随水泥掺量的不同而发生变化;峰值强度、残余强度随水泥掺量及围压的增大而增大;临界应变(峰值强度对应的应变)则随围压增大而增大,随水泥掺量的增大而减小.

Application of the biological conjugate between antibody and colloid Au nanoparticles as analyte to inductively coupled plasma mass spectrometry.

This paper describes the study of atomization of nanoparticles by inductively coupled plasma mass spectrometry (ICPMS) and developes a novel nonisotopic immunoassay by coupling sandwich-type immunoreaction to ICPMS. The goat-anti-rabbit immunoglobulin G (IgG) labeled with colloidal gold nanoparticles served as an analyte in ICPMS for the indirect measurement of rabbit-anti-human IgG. Matrix effect studies showed the gold signal was not sensitive to the organic matrix. A relatively good correlation (r2 = 0.9528) between the proposed method and enzyme-linked immunosorbent assay has been obtained. The method may have significant potential as an important ICPMS-based nonisotopic immnoassay method for the simultaneous determination of biologic analytes of interest by labeling different kinds of inorganic nanoparticles.

Development of a gas sensor utilizing chemiluminescence on nanosized titanium dioxide.

A gas-sensing mode based on chemiluminescence generated on the surface of nanosized materials is proposed in the present work. Seven nanosized materials were tested, and chemiluminescence was detected from six of them during the catalytic oxidation of organic vapors in air. The luminescence characteristics of ethanol and acetone vapors passing through the surface of TiO2 chosen were studied with a chemiluminescence-based detection system. The linear range of chemiluminescence intensity versus concentration of organic compounds is 40-400 microg/mL for ethanol and 20-200 microg/mL for acetone dissolved in water, respectively. X-ray powder diffraction and Raman spectrometry were used to investigate the changes in catalytic activity of TiO2 after a 60-h reaction at 380 degrees C. The results showed that the carbon deposited on the surface of TiO2, decreasing the catalytic activity, but can be removed in air by controlling the temperature at 500 degrees C for 3 h. Regenerability and no consumption of sensor substrate signify the long lifetime of the gas sensor.
