岚皋绿色辉石捕虏体矿物学及其地质意义

产于扬子板块北缘岚皋县境内的早古生代镁铁－超镁铁质煌斑杂岩中的绿色辉石捕虏晶及捕虏体，按其岩相学及化学成分可分成三种类型，它们是同一种岩浆在不同深度结晶分异的结果。绿色辉石岩系列是早古生代大陆边缘裂谷中超碱质基性岩浆活动的产物。同寄主煌斑杂岩的初始岩浆（煌斑岩浆）一样，是于裂谷作用不同阶段由交代富集的亏损地幔部分熔融所形成。     

地震区多层石结构抗震抗剪能力的模糊可靠性分析

本文通过考虑地震烈度的随机性和模糊性,以及石结构强度破坏等级界限的模糊性,研究多层石结构抗震抗剪能力的可靠性问题.将地震地面运动模拟为含有模糊烈度参数的平稳过滤有色噪声的随机过程,引入抗剪强度破坏指数,建立了石结构抗震抗剪能力的模糊安全准则,为研究多层石结构的抗震抗剪能力可靠性提供了一个合理的评定方法。     

东营凹陷南坡近地表化探研究

利用引进的近地表化探系统,在济阳拗陷东营凹陷南坡的草桥油田进行了化探资料的采集、分析、处理及解释。研究证明:该系统在资料采集和现场质量控制方面有着明显的技术优势,在己知油田的断层、油水边界和油层尖灭线都有明显的地化异常。通过各种方法实验,对烃类在纵向上、横向上的丰度变化进行了初步探索。

应用放射性同位素x射线荧光分析仪测定各种元素含量在许多文献中均有报道。本文主要介绍84A86型轻便x射线荧光分析仪首次在福建省紫金山铜矿区测定粉末样、块状岩心、坑道壁中铜矿的含量及其所取得的经济效益。     

黑龙江省五大莲池火山群中老黑山熔岩磁组构特征分析

近一二十年,岩石磁学有了飞速发展,并在地质学领域内占有越来越重要的位置。国内外研究的焦点是磁组构与应变相关性以及磁组构在岩浆岩、沉积岩构造分析中的应用。本文着重研究了未变形火山熔岩的磁组构特征,为火山岩的磁组构与有限应变相关性等项研究提供基本对比参照体系,也为室内有关的模拟实验提供依据。

第23周太阳活动峰年北京天文台太阳射电观测

An introduction to the instrumonts to be used for solar radio observations in Beijing in Solar Cycle 23 is made in this paper. They are 10cm solar radio telescope which has been used for a long time,and 1.0～2.0GHz,2.6～3.8GHz and 5.2～7.6GHz spectrometers. The former two spectrometers has passed a test,showing high guality,and the 5.2～7.6GHz one will be in operation from 1999. It is believed that highl gualified data should be obtained in the next solar cycle.     

Seeing Conditions at Sutherland. Results of the 1992/93 seeing campaign

In order to decide whether the seeing conditions at SAAO/Sutherland justify the erection of a 3.5 m telescope and also to compare Sutherland with the Gamsberg/Namibia site, a seeing campaign covering 15 months has been carried out. For direct comparison with the results of the seeing campaign at Gamsberg twenty years before the same QUESTAR telescope was employed. The seeing is determined by the scattering of the star-trail exposed on a film in the focal plane of the telescope. The campaign commenced in February 1992. Up to May 1993, data for 204 nights, that is 47.3% of the total number of nights, were collected. Due to wind speeds above 30 km h^-1, 25 out of the 204 nights were not considered in the final reduction. The useful 179 nights are evenly distributed over the campaign period. The median seeing value for the whole period is = 0.52. There are differences during the year: the best season gives = 0.42, the worst = 0.67. Each night was divided into three intervals, although data for each of the three intervals were not always available. Generally, there is an improvement in the seeing during the course of a night. The results are compared to the seeing values of Gamsberg/Namibia and ESO/La Silla.
