建议一个弥补震害资料不足的方法

本文用模糊贴近度原则作类比,提供了一种弥补震害预测时历史地震资料不足的方法,途径是将一个烈度之下的震害经验推广到其他烈度上去用。实践证明,用这种建立在近似推理基础之上的方法推导出来的结果,在总体趋势上和真实情况完全一致。     

Anisotropy of magnetic susceptibility parameters: Guidelines for their rational selection

Twenty-eight parameters used to characterize measurements of the anisotropy of magnetic susceptibility are compared theoretically in this work by introducing the concept of the field of susceptibility tensors, which allows the representation of parameters as families of lines in a plane. It is demonstrated that the foliation and lineation parameters are but a special case of the shape parameters, implying that the resolution of these two rock fabric elements using AMS measurements alone is more an artifact of the numerical range of definition of some parameters than a quantification of two physically independent features. Also, it is shown that parameters presumably of the same type do not necessarily yield equivalent interpretation of results in a qualitative sense, and therefore, caution should be strongly exercised when parameters are to be selected. Paramters quantifying the degree of anisotropy are, in general, equivalent to each other because of the very small departure observed in natural rocks from the isotropic case. However, a final consideration of the possible ability to differentiate rock types and a convenient range of values allowing expression of the degree of anisotropy in a well-defined percentage are pointed out as the main factors to be considered before selecting one parameter within this class.     

中国主要自然致灾因子的区域分异

依据１０２种自然致灾因子分布图，以县域为统计单元，建立了全国自然致灾因子数据库。在此基础上，绘制出中国自然致灾因子多度、相对强度、被灾指数图，进而分析了它们的区域分异，为进行中国自然灾害区划提供依据。

临汾盆地现代地震活动特征及其与深部构造关系初探

本文分析了临汾盆地现代地震在时序分布上的阶段性，平面分布上的丛集性，及其震源三维分布与分布地深部构造的关系，指出盆地北部的临汾－洪洞凹陷为该区未来若干年内的主要发震区，而２０－３０ｋｍ深度则是主要发震层次。

苏北平原井下摆观测效果的讨论

文章以江苏省大丰台、盐城台、淮阴台、海安台，射阳台井下摆观测为例。比较它们的观测结果，分析认为井下摆的观测效果不仅与地面复盖层的厚度有关，而且与井下摆周围的环境干扰，观测用井的质量有关。为了提高井下摆观测效果，应尽量减少环境干扰，并注意井的垂直度和固井，文章还指出，沿海地区井下摆受海浪干扰相当显著的。     

深部气层和干层测井模糊综合评判

深部气层和干层的区分是常规测井解释的难题。认识始于实践。本文依据东濮凹陷深层试采资料,建立了两个模式各四个参数的隶属度曲线,进行气层和干层模糊综合评判研究,并用该地区深层试井资料作了检验,效果颇佳。证明模糊综合评判是区分深部气层和干层的一种行之有效的方法。     

EFFECTS OF THE ENVELOPE DEGREE OF OROGRAPHY ON THE SIMULATED CLIMATE PROPERTIES

A primitive equation model with a zonal domain and a p-σ incorporated vertical coordinate systemis used to study the effects of the envelope degree of orography on the simulated properties of bothwinter and summer climates.Results show that the orography with a larger envelope degree can im-prove the simulations to certain extent,especially in winter.It is found that the simulated propertiesof climate are mainly determined by the co-effects of the land-sea and the orographic distributions,and the envelope degree of orography has a secondary effect.However it should be taken properly inorder to improve simulations:otherwise,it would be harmful.Different envelope degrees of orogra-phy can be adopted in different areas.
