The historic and artistic heritage facing the earthquake risk: The Italian case

The problem of protection against earthquakes in Italy is made difficult by the presence of a huge historic and artistic heritage. Such a heritage is mainly made up of ancient buildings and monuments situated in the urban centres, which are densely distributed throughout Italy. Therefore, very complex problems are met in the determination of the value parameter concurring with the determination of seismic risk, in addition to hazard and vulnerability. An indication of the monetary value of a building is not sufficient as far as the cultural heritage is concerned: different criteria are necessary in order to distinguish which are the strategic buildings. If we consider that there are more than 2000 museums in Italy, most of which are placed inside historic buildings, it appears that museums should receive the highest priority in future initiatives for seismic rehabilitation.     

工业区与非工业区辐射雾水的化学组成

1988年冬季，你们对云南省安宁工业区和西双版纳非工业区雾水进行采集，工业区雾水混浊肮脏，含有大量固体颗粒，雾水中离子浓度值与附近工厂排向大气的污染物有关，但雾水酸度值并不高。非工业区雾水比较清洁，雾水中离子浓度值平均比工业区低一个数量级。本文还讨论了一个雾过程离子浓度变化与温度层结的关系。     

拉萨近地层风廓线模拟

本文利用1986年中美联合青藏高原大气科学试验期间的考察资料,研究了拉萨近郊风廊线的特征。从莫宁——奥布赫夫相似理论出发,建立了青藏高原近地层风廓线模拟的模式。     

地震信息对薄砂岩储层特性的描述

近年来,以地震信息为主进行油气藏描述,这是当前对石油勘探的重点攻关课题.本文结合我国陆上和海域部分油田或含油气构造的实际资料,运用地震信息为主,结合测井、地质及钻井等资料,对储层进行综合解释。同时,提出了用多地震信息计算薄层厚度的基本公式,根据地区性岩性和地震资料的差异,使用了确定性地质统计和Coringing分析两种方法进行储层物性参数的预测,文中给出大量的实例说明各种储层参数描述方法和应用效果。     

Multi-layer Tectonic Model for Intraplate Deformation and Plastic-Flow Network in the Asian Continental Lithosphere

In a large area of the east—central Asian continent there is a unified seismic network system composed of two families of large—seismic belts that intersect conjugately. Such a seismic network in the middle—upper crust is actually a response to the plastic flow network in the lower lithosphere including the lower crust and lithospheric mantle. The existence of the unified plastic flow system confirms that the driving force for intraplate tectonic deformation results mainly from the compression of the India plate, while the long-range transmission of the force is carried out chiefly by means of plastic flow. The plastic flow network has a control over the intraplate tectonic deformation.

马边-永善地震带构造形式及地震特征

根据该地褶皱形态、断裂特征、应力场分布等资料研究,指出马边～永善及其两侧的构造形迹自西而东有一个相应强～弱变化过程。推测其力源主要来自西部喜马拉雅构造域的侧向推挤,所形成的马边-永善地震带是处于马边-昭通-曲靖断裂构造带的一部分,从而成为川西经向构造带的东部边界,也是青藏高原东南边缘与四川盆地西南边缘的浅部界线     

用地震活动性指数A（b）等资料判断图像以后有无主震及震级大小

用 A(b)指数判断图象以后有无主震,其效果颇好。A(b)指数能将有主震 M_L≥5.0与有主震 M_L≤4.7(或无主震)区别开来。再加地震活动的范围、强度资料的配合,能判断主震的大小。此方法的资料自检准确率陆地达96%,震例检验的准确率也高。这样的判断,对用图象作地震预报有重要的作用。
