1Biot反演在夏威夷钙质沉积物原位测量声速和衰减中的应用显示文摘对夏威夷檀香山岛的两个站(H3和H4)钙质沉积物进行了20~100kHz的原位纵波声速和声衰减测量.它们均有轻微的频散.随频率的增加H3站位声速从1691m/s增加到1708m/s,H4站位的声速从1579m/s增加到1585m/s.随频率的增加H3站位的有效衰减从15dB/m增加到75dB/m,H4站位的有效衰减从22dB/m增加到62dB/m.运用Biot Stoll模型对所测得的纵波速度和声衰减数据进行了Biot模型未知参数反演,发现粒径较大的H3站的沉积物(孔隙率为45%)比粒径较小的H4站的沉积物(孔隙率为56%)具有曲率小和渗透率及孔隙半径都大的性质.陶春辉 BAFFI S WILKENS R H FU S S RICHARDSON M D 金翔龙 2005海洋学报2005,27,3:15
2采用计量型扫描力显微镜校准微纳米标准样板显示文摘为了建立质量保证体系,微米和纳米样板至今仍被广泛地应用于校准微纳米尺度的测量仪器中.介绍了应用由德国联邦物理研究所开发研究的、测量范围为25 mm×25 mm×5 mm的计量型扫描力显微镜(M-LRSFM)的校准方法.上述计量型扫描力显微镜配置有三个零拍的激光干涉仪,可分别测量沿x、y、z三条轴线方向的位移,因而其测量值可直接溯源于“米”定义.此种M-LRSFM能够校准横向的微纳尺度的结构尺寸,诸如阶梯高度、一维和二维光栅、镀层厚度、线宽、微纳尺度的表面粗糙度等.作为实例,介绍了一种横向样板的校准程序及获得的校准结果.研究表明这种方法适合于校验扫描电子显微镜(SEM)的放大倍率.戴高良 KOENDERS Ludger DANZEBRINK Ulrich WILKENING Günter 周健雄 陈振宇 2006纳米技术与精密工程2006,4,1:8

4地球磁尾两种不同类型磁结构形成机理显示文摘观测表明, 横越磁尾等离子体片和尾瓣的磁场By分量正比于行星际磁场By分量, 并且行星际磁场与等离子体团内By分量极性相同, 因此磁尾等离子体团应该是一个三维结构. 以两类磁静平衡解为初态, 对亚暴期间磁尾动力学过程作二维三分量模拟研究. 数值结果展示了By分量两类不同的演化特征, 它们分别与具有通量绳核心的磁结构及类似于“闭合环”的等离子体团型磁结构相对应. 由此认为, 亚暴期间在地球磁尾中出现不同拓扑位形的磁结构可能与具有不同By分量分布形态的磁场重联有关.金曙平 胡先鹏 崔海龙 刘振兴 濮祖荫 B.

6Study of A Geo-Acoustic Model of Gas-Bearing Sediment and Its Application in Sediment with Low Acoustic Veloctiy显示文摘A new geo-acoustic model for gas-bearing sediment is proposed based on the work of Dvorkin and Prasad,and Biot theory.Only five geophysical parameters:sediment mineral composition,free gas saturation,tortuosity(also known as the structure factor),permeability,and porosity,are considered in the model.A benefit of this model is that we need only five parameters instead of ten parameters in the Biot's formulas for acoustic velocity and attenuation calculation.Here the model is demonstrated with the in-situ experimental data collected from the Hangzhou Bay,China.The results of this study suggest that free gas content in sediment is the most critical condition resulting in a low acoustic velocity(compressional wave).The respective contributions of the other four parameters in the model are also discussed.陶春辉 李红星 邓显明 周建平 FU Shun-sheng R.
