大气科学 , 1983, DOI: 10.3878/j.issn.1006-9895.1983.03.12
Abstract: 本文先从引证华南前汛期暴雨实验(1977、1978)中几个突出个例入手,继而分析海南岛四周濒海台站、北部湾北部海面以及广东广西沿海部分台站的10年(1961—1970)平均地面流场①,揭露了海南岛地形造成的绕流这一观测事实,并初步研究了这种绕流辐合对粤桂沿海地区降雨的影响。

Abstract: The grain boundaries in nanocrystalline palladium synthesized by the inert gas condensation and in situ compacting method have ordered and imperfect or disordered regions. Nanovoids are also observed at the interfaces. High density of dislocations are detected inside the grains and at the grain boundaries. Most of the interfaces in nanocrystalline Ti-Ni-Si and Fe-Mo-Si-B alloys produced by the amorphous crystallization have ordered structure. No obvious disordered regions and nanovoids are observed at the interfaces. However, the lattice fringes near the ordered grain boundaries or interfaces regions in the nanocrystalline materials produced by the various process show curved and a little distorted appearance. In comparison with the nanocrystalline palladium, the nanocrystalline alloys obtained from the amorphous crystallization have much lower density of dislocations.

Abstract: Structural relationship between Z and T phases in a rapidly solidified Al-Li-Cu-Mg-Zr alloy has been studied by high-resolution electron microscopy and conventional tramission electron microscopy. The result shows that there exist two well de- fined orientation relationships between Z and T phases. The observed structural faults in Z and T phases could be interpreted. The structrues of the two phases is closely related to each other, certain faulted structures in one phase can be seen as the other phase when the faulted area is extended.
A HREM IMAGE ANALYSIS FOR GEOMETRICAL MISMATCH AT INTERFACES
两相界面几何错配的高分辨电子显微象分析

Abstract: The normal interface analysis procedure is that to calculate the mismatch between two sets of lattice planes of the two corresponding matrix phases based upon the lattice parameters, then to compare the rseult with the observed interface dislocation arrangement. This work investigates the cases where misfit dislocations should exist at the interface according to prediction from geometrical mismatch analysis, however, very good coherent match at such interface in fact appears in the observed high resolution electron microscopy (HREM) images. The fact implies that the structural similarity between two phases can accommodate a rather large geometrical mismatch at the interface.

Abstract: 对恩施断裂中段构造地貌、断裂剖面与洪积扇变形的分析表明,断裂在第四纪活动明显,以正倾滑兼右旋走滑为特征。根据洪积扇位错的水平距离、垂直高差以及形成时代,估算出断裂在中更新世晚期至晚更新世早、中期的右旋运动速率为0.43~0.5 mm/a,垂直运动速率0.07~0.17 mm/a。

Abstract: Aluminum-Lithium alloys is of considerate interest to the aerospace community due to their high strengths and stiffness. Basic research in the Al-Li based systems was stimulated once more since the icosadral quasicrystal T2-A16Cu3Li was observed in the Al
冬、春季冷锋影响桂南与否的判别

高原气象 , 1984,
Abstract: 本文普查了1965年11月至1974年4月共10年(冬春)的历史天气图,统计了该期间越过中苏(蒙)边境南下的323次冷锋活动。统计中我们着眼于高原地区中、低对流层的温度场动态,以有无阿拉伯海暖舌向高原上空发展为判据,区分过中苏(蒙)边境的冷锋能否南下影响桂南地区。
