CBERS-1红外遥感器图像处理系统设计

红外多光谱扫描仪（IRMSS）是中巴地球资源卫星（CBERS）上的重要有效载荷之一。其获取的红外图像可以在国民经济的各个领域得到广泛应用。但是由数传系统传回的图像数据不能直接用,必须经过相应的处理。文章介绍的内容就是如何设计一个处理系统,将这种不可直接用数据经过解码和图像格式的处理,得到可视图像;经过图像预处理,得到零级图像;经过相应的辐射校正处理,得到一级图像:经过几何校正处理,得到二级图像产品,提供给其它经济各部门加以应用。

钛酸铝陶瓷的制备

采用固相法一步烧成Al2TiO5时,为了保证反应充分进行,防止反应过程中晶粒的异常长大,采用湿法球磨的方法使反应原料Al2O3和Anatase-TiO2充分混合均匀。研究了球磨过程中Al2O3和Anatase-TiO2料浆的pH值对料浆中颗粒Zeta电位的影响和分散剂的添加量对料浆粘度以及烧成制度对反应产物的影响。研究表明料浆的pH值为9.7和分散剂的添加量为0.6wt%(相对固相粉体的质量)时可以制备出均匀的Al2O3和Anatase-TiO2悬浮料浆;料浆经注浆成型干燥后得到的坯体,在1450℃保温两小时,固相反应得到充分进行,全部生成Al2TiO5。     

T cell regulation in microgravity – The current knowledge from in vitro experiments conducted in space,parabolic flights and ground-based facilities

Dating back to the Apollo and Skylab missions, it has been reported that astronauts suffered from bacterial and viral infections during space flight or after returning to Earth. Blood analyses revealed strongly reduced capability of human lymphocytes to become active upon mitogenic stimulation. Since then, a large number of in vitro studies on human immune cells have been conducted in space, in parabolic flights, and in ground-based facilities. It became obvious that microgravity affects cell morphology and important cellular functions. Observed changes include cell proliferation, the cytoskeleton, signal transduction and gene expression. This review gives an overview of the current knowledge of T cell regulation under altered gravity conditions obtained by in vitro studies with special emphasis on the cell culture conditions used. We propose that future in vitro experiments should follow rigorous standardized cell culture conditions, which allows better comparison of the results obtained in different flight- and ground-based experiment platforms.

Fabrication of Ti/Al/Mg laminated composites by hot roll bonding and their microstructures and mechanical properties

Ti/Al/Mg laminated composites were successfully fabricated by hot roll bonding. The effects of the rolling reduction on the microstructural evolution and mechanical properties of the composites were explored. The results show that Ti/Al/Mg laminated sheets exhibit good interfacial bonding. The rolling reduction has a significant effect on the deformation inhomogeneity through the thickness of the Al layer. The initial grains of the Al layer near the Ti/Al interface are fragmented into fine equiaxed grains, and the grains at the center and near the Al/Mg interface are elongated. The R-cube shear texture of the Al layer forms near the Ti/Al interface and permeates into the center layer in the samples with greater rolling reductions. The β-fiber rolling texture of the Al layer is observed near the Al/Mg interface and increases with the increase of rolling reduction. The stress–strain curves indicate that the fracture appears first in the Mg layer. With the increasing rolling reduction, the ultimate tensile and yield strength values increase, and the elongation up to the Mg layer fracture decreases.
