Gauss-Markov模型的岭型GM估计

针对目前文献中提出的各种抗差有偏估计没有对设计空间的粗差进行控制的问题,将岭估计与GM估计结合起来提出了一种新的抗差有偏估计———岭型GM估计,理论分析和计算结果均表明岭型GM估计不仅能消除法矩阵病态性的不良影响,而且能同时具有观测空间和设计空间的抗差性,是一种性能良好的估计。     

库区蓄水型人工增雨效果评估及其应用

通过对降水影响系统分型,给出了以同一影响天气系统下的降水时段为评估单元,对降水前后目标区和控制区的流域面雨量、入库流量和作业前后雷达回波参量进行评估,并对2005年夏季增雨作业个例进行了计算,结果表明,雷达回波参量在作业前后有明显的变化,平均增雨率为19.61%,投入产出比为1:37,经济效益显著。     

首批证认8个密云射电源为BLLac天体和类星体

为了深入研究密云射电源表分类样本的性质,作为系列工作的第一部分,选出了一个２３２～４８５０ＭＨｚ平谱源样本．１９９８年５月２９至３１日,利用北京天文台２．１６米望远镜和ＯＭＲ摄谱仪,对其中１８个目标进行了观测及光谱认证．结果共证认出１５个ＡＧＮ,其中３个信噪比不小于８的ＢＬＬａｃ天体和５个类星体（最大红移为２．５１９±０．００３）是新发现的．     

构造应力作用下流体运动的动力学分析——构造流体动力学

本文从流体动力学的基本规律出发,应用渗流力学、岩土力学及弹性力学的理论及方法,推导出了考虑应力状态的可变形介质中流体运动的动力学方程,由该方程可以看出：应力状态是影响流体运动的一个非常重要的因素,它通过３种方式来影响流体的运动,其一是：应力的作用改变介质的渗透性能,从而影响流体运动;其二是：平均正应力的变化速率影响介质的含流体能力,它以源汇项的形式反映在方程中;其三是：应力的作用影响流场的初始状态及边界状态,通过影响定解条件反映在动力学方程中,从而影响运动特征。构造应力场对流体运动的最终影响是这３方面作用     

INVESTIGATION OF STATUS AND DEMAND ON PUBLIC SERVICE OF EARTHQUAKE DISASTER MITIGATION IN CHINA

In order to make a comprehensive and systematic evaluation of the status and demands of public service of earthquake disaster mitigation, we launched an investigation with Social Opinion Polling Center of National Bureau of Statistics on the current situation of public service of earthquake disaster mitigation and the demands for it in 2018. The investigation was conducted for 18~75-year-old residents for both urban and rural areas in 31 provinces of China mainland using the Computer Assisted Telephone Interview(CATI)method and 20 078 valid samples were received in total. The questionnaire mainly includes two parts: the current situation assessment and the demand survey. The assessment of public service status consists of five indicators: earthquake emergency drill, knowledge publicity of earthquake prevention and disaster reduction, acquisition of earthquake information, reliability of information released by earthquake agencies, and overall satisfaction. The results indicate that only 27.4% of public have participated the earthquake emergency drill, and 73.5% of public have learned some knowledge about earthquake prevention and disaster reduction in different level. It shows that rural residents have a lower level of scientific knowledge of earthquake disaster mitigation although the rural residents have a higher level of satisfaction. Meanwhile, 82.9% of the public are very concerned about earthquake-related information, and the earthquake information acquisition convenience score is 81.51 points(the full score is 100 points). At present, TV is still the most popular way to obtain the earthquake-related information, besides that, network and the new media app such as Wechat and Weibo play a more and more important role. In terms of the reliability of official information published by the earthquake administration, the score is 83.69 points which indicates that the public tend to believe in official departments. Furthermore, the degree of satisfaction evaluation of public service of earthquake disaster mitigation is marked 76.44 points which shows that there is still much room for improvement. The more educated the public, the less satisfied they are with the public service of earthquake prevention and disaster reduction. The results also show that 51.81% of the public are willing to obtain earthquake warning information at their own expense. As for the demand, the most expectative services for the public are post-earthquake rescue and reconstruction, earthquake warning, and house earthquake resilience test. The results of the investigation may provide some reference for the government to provide better services of earthquake disaster mitigation and to make scientific knowledge popularization in a more scientific way.

华北地区几次大震前的b值异常变化

研究了华北地区几次大震周围的较小区域内和较大区域内的b值变化.发现了较小区域内的b值随时间先升高后逐步降低,直至最低值,震前又有所回升才发震;较大区域内的b值随时间的变化,在大震前有个明显的峰值期,其峰值期的长短与大震震级有关. 另外,研究了b值从大震震中向外随区域扩展的变化,发现b值从震中向外有逐步增高的趋势.在大震震中附近有个低b值区域,其外围有个高b值区域.
