The effects of small grains set on the surface of prolate spheroid on SFL were also observed and analysed. In laminar flow, Re=1. 4×10〓, the shape of separation line is affected prominently by the nearby grains.
层流状态下，雷诺数为1.4×10〓时，分离线附近的颗粒状突起会显著影响分离线的形状，当雷诺数减为0.9×10〓时，颗粒对分离线只有微弱的影响。

The observation under microscope, the analysis of Au. Ag. Cu. Fe. As content by electron probe and the micrograph of gold grains, confirm that placer gold are natural Au-Ag alloys. The structure and chemical compositions of verge and interior of gold grains differ significantly for large grains but little for small grains and those which intergrow with guartz and limonite.
镜下观察、电子探针分析(Au、Ag、Cu、Fe、As含量)及显微照相等研究，证实了砂金是天然Au-Ag合金，其边部与内部的结构、成分具有不均一性，这在中粗粒金中表现尤为明显，而细粒金及带连生体的金常常不具备这一特点。

Also the phase transition temperature from hexagonal ZnTiO_3 phase to cubic Zn_2TiO_4 was lowed by adding V_2O_5. It was noticed that V enriched in the boundary of the exaggerated grains, while not be detected in the inner of exaggerated grains or in the boundary of small grains. At sintering temperature 50℃, orthotitanate phase Zn_2TiO_4 in zinc titanate ceramics with ≤1.00wt% WO_3 additions became major phase, while zinc metatitanate ZnTiO_3 became major phase with ≤1.00wt% WO_3 additions.
结果表明：单独掺杂V_2O_5和WO_3有效降低了陶瓷烧结温度，900℃烧结的掺杂0.75wt%V_2O_5钛酸锌陶瓷密度可达理论密度的96.1%，930℃烧结的掺杂3.00wt%WO_3钛酸锌陶瓷的密度达理论密度的95.2%；V_2O_5的添加使六方相ZnTiO_3的分解温度从900℃降到了850℃以下，V_2O_5富积于陶瓷体的晶界处，在V_2O_5富积区附近产生了异常长大的晶粒。
