The measurements of current-voltage characteristic at various temperatures and applied fields have shown that resistanceless currents persist at fields up to 8T before flux flow resistance is detected for polycrystalline Tl_(2) Ba_(2) Ca_(2) Cu_(3) O_(10)(TBCCO)superconductor with high *** improvement of the grainboundary properties and possibility of high ability of transport current have also been *** microstructure examination and magnetization measurements support strongly these results.

Susceptibility measurements on Bi_(2)Sr_(2)CaCu_(2)O_(8) single crystals do reveal field-induced-suppression of sharp phase *** apparent anisotropy of the susceptibility was observed when magnetic field was applied along the three main directions a,b and *** three dimensional isotropic fluctuation diamagnetism theory is proposed to explain our experimental finding of isotropic *** a wide range of magnetic field,the temperature dependence of susceptibility does not show any obvious change in its character when the sample enters into expected vortex-lattice state from vortex-liquid state.

Based on palaeomagnetic studies of the Precambrian gold deposits in the Xiong'ershan area, Henan Province, the authors infer that the ore-forming processes of the Beiling alteration-type gold ore deposit and the Dianfang breccia-type gold ore deposit started in the Proterozoic, and was superimposed by later mineralization, whereas the mineralization age of the Jiguanshan quartz- vein type gold ore deposit is Yanshanian.

T1BaCaCuO 超导样品是颗粒状的陶瓷体。对样品的 X 射线衍射分析证明主要由 Tl-2Ba_2Ca_2Cu_3Ox 和 Tl_2Ba_2CaCu_2Oy 两相组成。对直径为十微米的颗粒用能量色散 X 射线(EDAX)、高分辨电镜(HREM)、电子衍射及计算机模拟象研究证实,颗粒可以是单相的,也可以是两相共生(INTERGROWTH)的。详细地研究高温相 Tl_2Ba_2Ca_2Cu_3Ox 的晶体结构,确证此相是钙钛矿型结构,由几个基元堆成。还首次观察了这一高温桐的晶体缺陷,包括晶界,颗粒边界的形态,位错和层无序等。
