A kind of acoustic phased arc array with circumferentially controlled directivity presented in this paper can be used to make acoustic logging with circumferential azimuth detection function.

为了实现声波测井的周向分辨能力，提出了可应用于声波测井的、具有周向辐射指向性的相控圆弧阵声波辐射器方案。

To establish new methods for highly sensitive time-resolved fluorescence bioassay, several new lanthanide fluorescence complexes were synthesized and used for the preparations of nanometer-sized lanthanide fluorescence biolabels. Novel lanthanide fluorescence nano-biolabels are uniform (25-55 nm in diameters),strongly fluorescent with long fluorescence lifetime, highly photostable and biocompatible.

本项目以时间分辨荧光生物分析新方法的建立与应用为研究目的，在合成出几种稀土荧光配合物的基础上，建立了几种新型强荧光性纳米稀土荧光生物标记材料的可控制备方法，生物标记方法及其在时间分辨荧光免疫分析中的应用方法。

Diffusion mechanism,microstructure and optical properties of Ag/Si multilayerson annealing have been investigated by in situ X-ray diffraction,high-resolutiontransmission electron microscopy and UV-VIS-NIR spectrophotometer,Siliconatoms diffusing along silver grain boundaries is suggested as the main diffusionmechanism.

采用原位X—射线衍射、高分辨透射电镜截面观察和光吸收谱测试等手段研究了退火过程中Ag/Si多层膜的扩散、结构演变及光学性质变化，并与可固溶性金属/Si系多层膜进行了比较。揭示了Si原子沿Ag晶界的扩散为主要的扩散机制。
