- The subject of this paper is a discussion and analysis for the relationship of different oceanic environmental parameters influencing each other , and relationship of the statistical distribution between data errors and inverted parameters errors by numerical simulation in a representative oceanic environment
论文通过数值模拟方法，讨论和分析了典型海洋环境下，不同的环境参数在反演中相互影响的关系以及数据误差与反演参数误差之间统计分布的关系等问题。 - In the second part , we adopt a few typical error analysis methods , primarily including the relativity analysis and the regression analysis , to analyses the relative error and absolute error of the time error , spatial data error and statistic data error of the raw input data in the model . then , we take each influence factors in the model into the relativity analysis and the regression analysis . finally , we synthesize the results of the above error analysis to figure out the theoretic accuracy of that model as 87 %
第二部分主要是采用几种典型的误差分析方法，主要包括相关性分析和回归分析，对模型的原始输入数据的时间误差、空间误差和统计数据误差进行了相对误差和绝对误差的分析，然后又对模型中各影响因子进行了相关分析和回归分析，最后综合以上误差分析的结果得出该模型的理论精度为87 。 - In addition , these methods rarely consider the case of multi - stage preloading . several studies has been made to solve these problems : ( 1 ) , an error processing is present to manage settlement data . based on fairing filtration theory , a fairing program is compiled to fair the observed data . ( 2 ) , according to classical consolidation theories , an analysis model of settlement data has been built under conditions of multi - stage preloading
针对目前存在的问题，本文主要做了以下研究工作： ( 1 )建立了沉降观测数据误差处理流程，并基于光顺滤波理论，对沉降观测数据进行光顺处理，编制了光顺程序； ( 2 )结合经典固结理论，建立了分级加载条件下沉降数据分析模型。 - In this paper , the theories and techniques of data quality control are thoroughly studied by taking pudong construction and management geographic information system ( js - gis ) , including error analysis and accuracy evaluation of digitized data , sample tests of housing surveying product , the principle and method of disfigurement measurement of attribute data based on sampling theories , and total quality control techniques of gis data . these methods are implemented in the construction of js - gis . the main contents are as follow : 1

统计误差分布的讨论结果显示：在非线性反演方法中，数据空间误差分布与参数空间误差分布不相同，这种匹配方法估计的海底声速的准确性好于对密度估计的准确性；在扰动反演算法中，相同的数据误差分布条件下，反演的eof各项系数误差分布不同。
