介绍了"Collectors强震动台网数据处理系统软件"的整体设计思路和功能模块的实现过程,统计了近2年所接入的近千个强震动台站的数据汇集及产出情况,重点统计了近2年云南、四川、新疆发生的5.0级及以上地震的地震事件记录回收及强震动参数产出的用时情况。结果表明:系统软件能7×24 h连续、稳定、可靠、高效地自动化运行,在处置地震事件时,一般能在2~10 min内陆续完成地震事件的自动回收和强震动参数的自动产出,速报能力由软件推广前的小时级别跃升至分钟级别。 相似文献

At present the development together with an intensification of anaerobic processes calls for methods of observation and control. It is very important to know intermediate metabolites of anaerobic microorganisms and the activity of methanogenic ones. Presented analytical methods are GLC analyses of lower fatty acids, alcohols, aldehydes and ketones and components of biogas. The chromatography using steam as a mobile phase is also mentioned. The method of determining the fluorescent coenzyme F420 was tested and modified. This coenzyme is specific for methanogenic microorganisms and is closely linked with their activity. The determination of the total activity of the hydrogenase system of anaerobic microorganisms by means of the rate of the consumption and evolution of molecular hydrogen was also presented. The applicability and effectivenes of these methods were verified on natural samples. All the methods mentioned above give satisfactory results with available equipment, materials and techniques. 相似文献

Mostafa Baniasadi Mohammad Reza Zare' Mehrjordi Hossein Mehrabi Boshrabadi Hamid Reza Mirzaei Khalilabad Abbas Rezaei Estakhrooye 《Ground water》2020,58(4):560-570
In recent decades, increased extraction of groundwater for human and agriculture consumption has led to a substantial drop in groundwater level in large areas of across the world. Declining groundwater levels is a serious problem in itself and has multiple economic, social, cultural, political, security-related, and environmental externalities. The negative economic-environmental externalities of overextraction of groundwater in the Orzouiyeh plain in the Kerman Province, Iran, were evaluated using methods such as replacement cost, production function, market prices, shadow price, and the value of the input marginal product. After evaluating externalities, the Positive Mathematical Programming method was used to evaluate different water policies to reduce the consumption of groundwater. The total economic losses due to the externalities were calculated to equal 2.8 U.S. million dollars. The damages caused by environmental externalities were calculated to equal 436.1 U.S. million dollars. The results related to the positive planning model show that the best policy among different options, such as deficit irrigation policy or combined policies, involves implementation of pressurized irrigation systems. 相似文献
