四川松潘-甘孜褶皱带一直是地球科学家关注的一个焦点。近年来，石油地质学家也对它表现出了很大的兴趣。根据地震测深、重、磁、电等的探查，发现该褶皱带深部有一低速高导层，而对大火成岩省一峨眉玄武岩喷溢-地幔柱的认识深化均表明，四川松潘-甘孜褶皱带是可望获得油气勘探突破的靶区，重要的是断裂构造、圈闭、储集层的耦合与优化。     

Influence of process variables on the drying of potato slices

Investigation of the effects of varying air velocity, slice thickness, and pre-treatment with sodium chloride solutions and surface active agents on drying potato slices indicated that the drying occurred entirely in the falling rate period and was controlled by the mechanism of liquid diffusion. The rate of drying, and therefore the diffusion coefficients, increased with the addition of sodium chloride and surface active agents. Diffusion coefficients were also influenced by air velocity and slice thickness, suggesting that the rate of drying of potato slices is controlled by a combination of internal and external resistances.

Seismic safety of lifelines—an optimum design method

Lifeline systems are vulnerable to two types of hazards arising from potential earthquake sources. These are the hazard of a fault-rupture strike on elements of a lifeline system and the hazard of overstress induced in different elements of the system because of the ground vibration. An optimum design method is presented in this paper for the design of a lifeline system for a maximum accepted probability of failure because of any of the two modes of failure. The method may be used to determine an optimum path between a number of fixed points which represent supply or demand stations in the system.     

最大似然反褶积软件包的研制与应用

本文简明地介绍最大似然反褶积的基本原理、软件包的研制过程和应用效果。 最大似然反褶积是美国80年代研究出的一种地震资料处理新方法,它有效地解决了传统褶积模型中无法进行信噪分离的矛盾。经松辽盆地实践证明,它可以求出高分辨率和高信噪比的反射系数、最小相位化子波、合成记录、相对层速度和绝对层速度。与国外的VELOG和SEISLOG处理软件的处理结果相比,分辨率和信噪比均有很大的提高。 在软件包的研制过程中,我们主要解决了数学模型复杂和运算速度慢的问题,使最大似然反褶积在CYBER-855S计算机上成为可实用的数字处理技术。 该项技术在大庆油田朝阳沟地区进行了初步应用,结果表明,对薄层地震响应的分辨能力有明显的提高。与井岩性柱状图对比,6m以上的砂层都可以分辨出来,并且对应得比较准确。有些3m的薄层也可以找到。 该软件包的研制成功并在地震资料处理中得到应用,这在国内是首创。     

基于不同爆轰产物的格尼速度估算新方法（英）

A new method for prediction of Gurney velocity of explosives is introduced in which energy output is correlated with the heat of detonation, the number of moles of gaseous products of detonation per gram of explosive and the average molecular weight of gaseous products. It is assumed that the CHNO explosive reacts to form products composed of N2 , CO, H2O, CO2, H2,O2 and C（s） as determined by the oxygen balance of the unreacted compound. Good agreement is obtained between measured and calculated values of Gurney velocity as compared to previous correlations which assumed the reaction products to consist of N2 , H2O, CO2 and either C（s） or O2.     

Seismic Physical Modeling Technology and Its Applications

1. Introduction Seismic physical modeling technology is an important method for the research on seismic exploration theory and methods. In seismic physical experiments, the earth, mantle or field site are scaled down to physical models according to the similarity principle, and then the seismic field and its variation are observed in the laboratory for the research work on the theories and methods of the earth structure, earthquake forecasting, energy and mineral resource exploration, and engi…     

Geotechnical Investigation Strategies for Lunar Base

Geotechnical characterization of potential lunar sites will be a critical part of the planning and design process. The strategies used to conduct a geotechnical investigation will be dictated by the specific needs of the lunar base, the unique environment of the lunar surface, and general character of the lunar soils and rocks. This paper outlines some of the types of geotechnical information that will be important and identifies some of the more promising strategies which might be used to obtain such information in the lunar environment. Some of the most important geotechnical information for planning and site development will be related to construction in the lunar soil. In addition to construction concerns, geotechnical data for foundation design (or verification of predesigned foundations) will be needed. The geotechnical site‐characterization work should include geophysical techniques, supplemented by conventional mechanical boring and testing only to the degree necessary to correlate geophysical measurements with conventional soil properties and to investigate anomalies. Equipment used for geotechnical site characterization will also serve for mineralogical exploration. Several techniques for geotechnical investigation that may provide very useful information in an expedient manner are described. Geophysical methods include seismic and electromagnetic methods, including seismic surveys that utilize surface waves. Electromagnetic methods such as ground‐penetrating radar are fast, efficient methods for mapping the subsurface, although these techniques do not measure soil characteristics that can readily be correlated with engineering properties. Seismic methods provide information that may correlate with soil strength, compressibility, and excavatability. In‐situ physical testing will likely include penetration testing for direct physical measurement of lunar soil behavior.
