From the analysis of the magnetic susceptibility,TOC,TN,pigment,organic car-bon isotope ,HI,saturated hydrocarbon and 14C dating etc. of the sediment samples from coresof two boreholes in the Taihu lake,a knowledge of the evolution of paleoenvironment of thelake during the last 14ka is achieved. The results show that the lake has undergone the fol-lowing stages .. The Lake was at a low level ,or even became exposed during 14.3-13.3kaBP,reflecting an arid climate. There existed a transitional stage during 13.3-12.4kaBP,the climate being slightly warm and wet. There are indications of a cold and dry climate around 11.5kaBP,probably corresponding to the Younger Drays event ,comparable with other areas in east China.

本文根据东西太湖短柱岩芯的沉积物的物理、化学、生物指标的综合分析，讨论了该区距今14ka来的古气候变化过程，结果表明14.3-13.3kaBP，太湖水位低，环境指标甚至表现为暴露特征，反映了气候干旱：13.3-12.4kaBP，为偏暖湿的过渡阶段；该孔柱270-280cm(11.5kaBP左右)各类指标均明显更映冷干特征，可能是Younger Drays事件的记录，与我国东部其它地区有可比性；约10.9-10kaBP，这一时期是整个研究时段内一个较显著的温暖期。

Microanalyses have shown that during brazing Ti in AgCuTi alloy transferred preferentially to the surface of the cBN grit, and bonding behavior on cBN surface by AgCuTi alloy filler metal is realized through TiN and TiB2 which are produced by interaction between Ti atoms of AgCuTi alloy and N or B atoms of cBN surface. Thus, the chemical metallurgic bonding has been formed in the interface between AgCuTi alloy and c-BN grit.

单核／巨噬细胞在类风湿关节炎的发病过程中起着重要的作用。单核／巨噬细胞不仅仅能够产生很多前炎症细胞因子和化学因子，而且它可通过很多机制引起类风湿关节炎的软骨和骨的损伤。

PAA/PVA IPN hydrogels were prepared by a sequential method by which acrylic acid firstly. polymerizes and cross-links in PVA/water solution with UV irradiation,then PVA physical cross-linked hydrogels are formed in cross-linked PAA networksby freezing-thawing. The orthogonal test design method was used to optimize theexperimental conditions based on the mechanical and swelling properties of thehydrogels. The effect of the PAA and crosslinking agent contents on the microscopicmorphology of the PAA/PVA IPN xerogel was investigated by transmission electronmicroscopy, and on the mechanical properties of the hydogels was studied bymeasurements of mechanical properties.
