Secondly , precipitation from the radar estimating precipitation model ( rep ) are verified using a rain - gage network of 127 stations in order to show the effects of five methods : zi , optimal interpolation joint of optimal interpolation and kalman filter , kalman filter , and average method . the results show that the method of optimal interpolation and the method of joint have the lowest rms errors and the method of zi has the highest rms errors 结果表明:将地面雨量计值作为真值,则联合校准法和最优插值校准法得出的降水量计算精度最高,卡尔曼滤波校准法和平均校准法的计算精度低于联合校准法和最优插值校准法, zi关系法的精度最低。
This paper puts forward an unconventional method of joint inversion of seismic data and well - logging , the joint inversion of well - logging properties from seismic and log data based on intelligent algorithms for realizing and describing underground strata after studying conventional joint inversion of seismic data and well - logging , which can inverse well - logging properties directly . fine results have achieved in practice application . the study of this paper has considerable innovation , academic and theory value 本文对常规地震测井联合反演作了深入剖析,并针对其中存在的问题,为达到认识和描述地下地层的目的,结合智能算法的特点,提出并实现了一种突破传统思想的直接反演测井属性的地震测井联合反演方法? ?测井属性的地震测井智能联合反演方法,并在实际应用中取得了较好的效果。
Using the research achievements of predecessors , studying historical character of each small ethnic group in economic development , deeply analyzing its present condition , exploring its developmental course through the method of jointing the economic factor with non - economic factor , general character with individual character , qualitative analysis with quantitative analysis , comparing the horizontality with verticality , studying the economic development of 22 small ethnic groups 作者在应用前人研究成果的基础上,研究每个人口较少民族的经济发展的历史特点,深入分析其发展现状,探索其发展轨迹。采取经济因素与非经济因素、共性与个性、定性与定量分析相结合,横向与纵向相比较等方法对22个人口较少民族的经济发展进行研究。
Third , on the base of expatiating on experimental research method and theoretical research method of joints , the paper points out two kinds of valid methods , which are used to analyze the tube joints stress of dendriform structure by making use of semi - analytical method and inelastic large deflection finite element analysis method , confirms to apply the evaporative pattern casting process as the facture method of dendriform structure cast joints , and detailed dissertates the casting theory , casting process , generation cause and prevention measure of casting flaws , heat treatment method and inspection standard about cast steel joints 然后在阐述树状结构节点实验研究方法和理论研究方法的基础上,提出了利用半解析法和弹塑性大挠度有限元法两种有效分析树状结构管节点应力的方法,并给出两种方法的详细表达式及它们各自的优缺点。通过对铸钢件常见制作方法的介绍,确定了采用消失模法作为树状结构铸钢节点的制作方法,并详细论述了用消失模法制作铸钢节点的铸造原理、铸造工艺、铸造缺陷产生的原因及防治措施、铸钢节点的热处理方法以及检验标准。
In addition , the general headquarters / departments organized successive studies and exercises of communications and command at the joint operational level , training of landing and mountain operations , and research on methods of joint penetration operations , and explored the features and patterns of integrated network and electronic warfare 总部机关还相继组织了联合战役通讯指挥研练、登陆和山地作战训练以及联合突防战法研讨,并探索了网电一体战的特点和作战样式。
