m.thyl m.thacrylate (m.A) was grafted onto silk fiber in a one-step em.lsion system.using a diethylzinc and 1,10-phenanthroline com.lex. The reaction conditions were investigated by varying tem.erature and initiator to m.nom.r ratio. Fourier transform.infrared (FTIR) spectrum. therm.gravim.tric analysis (TGA), and scanning electron m.croscopy (SEC) techniques were used to characterize the structure, therm.l stability, and surface m.rphology of the obtained product, respectively. Grafting of m.A onto silk increased the therm.l stability of silk. The FTIR spectrum.and SEm.im.ges provided further evidence that m.A has been successfully grafted onto the silk fiber. A peak ascribed to the C=O stretching vibration of m.A was detected in the FTIR spectrum.of grafted silk fiber, which was not present in the spectrum.of pure silk fiber. m.reover, the SEm.im.ges illustrated the increase in diam.ter and surface roughness of grafted silk com.ared with pure silk. Lastly, the dyeing perform.nce of the m.dified silk was significantly increased.

1996和1997年，在日本TOKAI离岸Nankai海槽采集了四分量的海底地震检波器（OBS）数据。我们将OBS数据与多道地震数据（m.S）联合分析，研究甲烷水合物在沉积中的分布和特征。地震数据揭示了一个非常复杂的动态沉积史，受控于下沉的浊流沉积、活动通道、褶皱以及陡倾角断层。不管这点，表明气体水合物存在的似海底反射（BSR），很容易识别为一个振幅横向变化的反射。对于OBS反射数据，我们应用一种成像技术，获得的结果与多道地震剖面有很好的吻合。我们还应用模拟和反演程序揭示详尽的速度结构。东Nankai海槽水深在930至1160m.间的区域，OBS数据允许我们构建一个含9个地层的地球物理模型描述其最上部700m.沉积。旅行时反演给出了上升的P波速度，其值达到2100m.s。如此高的P波速度可以解释为部分的水合物饱和度达到孔隙空间部的20％。在海底以下320m.，BSR与P波速度的明显下降相对应，速度值大约降至1580至1750m.s之间。这一低速层厚约80m.S波速度通过广角数据的同相轴相关、时间拾取和正演模拟得到，在水合物稳定带其值达到700—750m.在BSR正下方，我们观测到s波的速度有小的下降。这可能暗示水合物对沉积基质的弱胶结作用。在更深的位置，高P波与S波速度表明沉积过固结，这归因于独特的压缩构造背景。

目的调查新建校舍室内空气中挥发性有机化学物质（VOCs）和甲醛（HCHO）等醛酮类化学物质污染现状,探讨污染的动态变化和危险性。方法以气相色谱-质谱法分析室内空气中VOCs污染水平,应用高效液相色谱法（HLPC）法检测空气中醛酮类物质,以观察污染的变化趋势。结果3种用途校舍使用初期,室内空气中13项VOCs指标均有不同程度检出,其中甲苯污染为主,占检出VOCs的90%以上,最高达3 044μg/m.3。室内空气中醛酮类物质呈多态样变化,甲醛污染水平以8月最高（230μg/m.3）,1年后降至使用初期的60%,呈伴时间推移逐渐降低的趋势,甲醛的释放与室温变化呈正相关（r〉0.6410,P〈0.01,n=13）;使用初期室内空气中丙酮和乙醛最高污染浓度分别为669和134μg/m.3;1年后降至52和49μg/m.3以下。结论校舍使用初期室内空气中VOCs和醛酮类污染普遍存在。空气中甲醛随使用时间的延长呈现伴夏季升高的螺旋样下降趋势;丙酮和乙醛呈波浪样下降;VOCs的污染水平使用初期最高,但下降较快,1个月后至初始的1/10~1/20。
