Based on a number of on-the-spot investigations,preliminary research on the macro-epicenter and meizoseismal region has been done.
在大量的现场实地调查基础上,对汶川地震的极震区和宏观震中分布点进行了初步的研究,分析认为汶川地震极震区与地表破裂带关系极为密切,极震区烈度为Ⅺ度,表现为强烈的带状分布;宏观震中与传统的宏观震中的认定有较大的区别,不再是一个点,而是一组点。
The primary results have been obtained by the analyses on the deviation of macroscopic epicenters from relevant microscopic epicenters determined rapidly after the 139 earthquake events occurred during 1989—2004.
通过计算中国大陆1989—2004年139次地震宏观震中与速报震中的偏离,得到了初步的结果;同时把中国大陆按照东经105°分为东部和西部,进一步研究分区特征,所得结果与整个大陆基本一致,都服从二维正态分布;最后给出了经验的中国大陆宏观地震震中—速报震中偏离的二维正态概率分布密度函数。
Fractal study of scale effect in microscopic,mesoscopic and macroscopic states for fracture mechanism of rock materials;
岩石材料微、细、宏观断裂机理尺度效应的分形研究
The macroscopic property of the material differs from its microcosmic property greatly,the existing macroscopic theory is usually no longer suitable under the condition of the mesocosmic or microscopic view.
材料的宏观性能与微观性能相差甚远,已有的宏观理论在细观或者微观情况下通常不再适用;为更好地理解材料的力学性能,需要进行宏观,细观、及微观三个层次相结合的三观研究,但如何将这三个层次的现象联系起来,无论对哪一学科都还是难题。
The microscopic oil production mechanism and macroscopic oil production mechanism are discussed in this paper, the main origin for the existing remaining oil in the round of injectors is analyzed.
