当前地质找矿工作的某些新动向与岩矿测试的新贡献 总被引:4,自引:3,他引:1
近年来地质找矿取得了一系列的新进展,也出现了以人为本的新趋势,现代的矿产地质工作面临着不分地区、不分矿种、不分专业的新动向,开拓国内和国外两个市场,利用国内和国外两种资源的新格局,要求地质找矿工作与岩矿测试工作密切结合.地质人员要充分了解现代测试技术的特点,充分发挥实验室和仪器设备的作用;实验室也需要主动为地质找矿工作提供支撑,针对“现、散、快、廉、难、全”的新特点研发相应的分析测试技术与设备,而不是被动地“来样品、出数据”;主管部门也需要在制定政策、规划立项时就安排好地质与测试工作的结合. 相似文献

海底浅表层信息声探测技术研究现状及发展 总被引:8,自引:0,他引:8
回顾了我国海洋仪器研发的历史,综述并对比了多波束测深、侧扫声呐和浅层剖面仪等海底浅表层信息声呐探测技术的国内外研究现状:经过数十年的海洋技术研发,国内在设备研发、数据资料处理方法研究和探测数据资料应用研究等方面已取得了较丰硕的研究成果,但同时也发现在当前国内海洋技术研发中仍存在一些潜在的问题,与国外相关海洋技术尚存在一定差距。以维护海洋权益为目标的系列重大海洋基础勘测项目的启动和深海资源勘查及研究的纵深发展是近年海洋技术得以快速发展的源动力。声学底质分类、声学海底原位测试、动力地貌和构造地貌等是目前海底浅表层声探测信息资料应用于海底科学研究的热点。对海洋技术的可持续发展提出了几点建议:①提高理论研究水平;②加快仪器设备研制的国产化进程;③加强自主知识产权数据处理软件的研发;④进行探测数据资料的深层次利用研究。 相似文献

The practice of conducting quality control and quality assurance in the construction of data sets is often an overlooked and
underestimated task of many research projects in the Earth Sciences. The development of software to effectively process and
quickly analyze measurements is a critical aspect of a research project. An evolutionary approach has been used at the University
of North Dakota to develop and implement software to process and analyze airborne measurements. Development over the past
eight years has resulted in a collection of software named the Airborne Data Processing and Analysis (ADPAA) package which
has been published as an open source project on Source Forge. The ADPAA package is intended to fully automate data processing
while incorporating the concept of missing value codes and levels of data processing. At each data level, ADPAA utilizes a
standard ASCII file format to store measurements from individual instruments into separate files. After all data levels have
been processed, a summary file containing parameters of scientific interest for the field project is created for each aircraft
flight. All project information is organized into a standard directory structure. ADPAA contains several tools that facilitate
quality control procedures conducted on instruments during field projects and laboratory testing. Each quality control procedure
is designed to ensure proper instrument performance and hence the validity of the instrument’s measurement. Data processing
by ADPAA allows edit files to be created that are automatically used to insert missing value codes into a time period that
had instrument problems. The creation of edit files is typically done after the completion of a field project when scientists
are performing quality assurance of the data set. Since data processing is automatic, preliminary data can be created and
analyzed within hours of an aircraft flight and a complete field project data set can be reprocessed many times during the
quality assurance process. Once a final data set has been created, ADPAA provides several tools for visualization and analysis.
In addition to aircraft data, ADPAA can be used on any data set that is based on time series measurements. The concepts illustrated
by ADPAA and components of ADPAA, such as the Cplot visualization tool, are applicable to areas of Earth Science that work
with time series measurements. 相似文献

Establishing the soil water retention curve, SWRC or the soil water characteristic curve, SWCC, is very useful for determination of unsaturated properties of soils. However, it has been observed that SWRC of a soil is not unique and depends on various factors such as the initial moisture content, density of soil, method of compaction, soil fabric and the path (drying or wetting) adopted for establishing it. In this context, many techniques and instruments have been employed by earlier researchers for determination of the SWRC of soils. However, these techniques entail weighing of the samples during prolonged testing, manually, and hence yield discrete data points. In this situation, AquaSorp® Isotherm Generator (manufactured by Decagon Devices Inc., USA) has been found to be quite useful for continuous determination of the drying-path SWRC of fine-grained soils. This device has been primarily employed for food products, powders and amorphous materials. Hence, demonstration of the utility and limitations of this device for SWRC determination of fine-grained soils becomes essential. With this in mind, extensive studies were conducted on commercially available soils (Kaolinite and Bentonite) by employing this device. In order to understand the influence of specimen specific parameters on the obtained SWRCs, the molding water content and thickness of the specimens were varied and the results have been evaluated critically. Details of the methodology adopted for these investigations, and the findings of the study are presented in this technical note. Based on a critical comparison of the results obtained from this device with those obtained from the dewpoint potentiameter, WP4®, the utility of this device for continuous determination of drying-path SWRC of the soils has also been demonstrated. 相似文献
