Indentation creep behavior with cylindrical flat indenters on the thermal barrier coating (TbC) was studied by finite element method (FEM). On ike constant applied indentation creep stress, there is a steady creep rate for each case studied for different creep properties of the TbC system. The steady creep depth rate depends on the applied indentation creep stress and size of the indenters as well as the creep properties of the bond coat of the TbC and the substrate. The possibilities to determine the creep properties of a thermal barrier system from indention creep testing were discussed. As an example, with two different size indenters, the creep properties of bond coat of the TbC system can be derived by an inverse FEM method. This study not only provides a numerical method to obtain the creep properties of the TbC system, but also extends the application of indentation creep method with cylindrical flat indenters.

The Fe/Mo multilayers were prepared by electron beam evaporation, the micro structure and magnetic properties of the multilayers were studied by X-ray diffraction, vibrating-sample magnetometer (VSM) et al. The experimental results revealed that the Fe/Mo multilayers in our experimental conditions behaved magnetoresistance effect with a sharp peak on magnetoresistance (MR) ratio curve, and magnetoresistance is easily saturated at low applied magnetic fields. For [Fe(1.5nm)/Mo(1.0nm)]4,2 multilayers, MR ratio could arrive to 0.1%. The antiferromagnetic interlayer coupling could be observed in some films at room temperature. The strength of the antiferromagnetic interlayer coupling J in the films is low because of the low saturation field Hs. The relationship between magnetic properties and micro structure was also discussed in this paper.

随着人民生活条件的改善以及各种与营养相关疾病的发病率逐年上升，人们对营养提出了更高的要求。如何定量评价某个体或群体的膳食营养状况并给予科学的膳食指导，这就要用到营养分析与评价系统。以往的营养软件多在DOS、Windows平台下开发的单机系统，专业性较强，且难以适应计算机技术的飞速发展，这就使得营养软件的使用仅局限于医院的营养主管部门及一些科学研单位，极大地制约了系统功能的发展，这就使得营养软件的使用仅局限于医院的营养主管部门及一些科研单位，极大地制约了系统功能的发挥。为改变这种状况，充分利用网络的强大功能普及营养知识，我们在本所研制开发的《上海市学生午餐营养与卫生评估》软件操作系统的基础上，开发了基于INTERNET的JS（健生）-膳食营养分析测试系统。使专业化的营养评分方法与要求人性化，能够进入到普通人的生活中，为广大人民群众提供日常膳食营养分析与科学的膳食建议。

Positive ionospheric storm effects that occurred during the superstorm on 20 November 2003 are investigated using a combination of ground-based Global Positioning System(GPS) total electron content(TEC),and the meridian chain of ionosondes distributed along the Latin America longitude of～280°*** the ground-based GPS TEC and ionosonde electron density profile data reveal significant enhancements at mid-low latitudes over the 280°E region during the main phase of the November 2003 superstorm. The maximum enhancement of the topside ionospheric electron content is 3.2-7.7 times of the bottomside ionosphere at the locations of the ionosondes distributed around the midand low ***,the height of maximum electron density exceeds 400 km and increases by 100 km compared with the quiet day over the South American area from middle to low latitudes,which might have resulted from a continuous eastward penetration electric field and storm-generated equatorward *** results do not support the conclusions of Yizengaw et al.(2006),who suggested that the observed positive storm over the South American sector was mainly the consequence of the changes of the bottomside ionosphere. The so-called "unusual" responses of the topside ionosphere for the November 2003 storm in Yizengaw et al.(2006) are likely associated with the erroneous usage of magnetometer and incomplete data.

＜正＞ Planarized Al processes have been investigated by electrical measurement and scanning electron microscopy to study their feasibility in building multi-level interconnect structures for VLSI circuits of sub micron geometry. A variety of test structures have been used to characterize these planarized Al processes. It has been demonstrated that 0.35μm via holes with nearly vertical side-wall can be filled without using collimated Al deposition. Contact resistance of about 0.3Ωand specific contact resistivity of approximately 6×10-10 Ω-cm2 were obtained for 0.5μm vias. Under optimized condition, very high yield was obtained for both 0.35μm and 0.5μm via hole fill.
