查询词典 observational error

For one-dimensional ocean temperature model, we optimally determined the initial and boundary conditions and related model parameters through variational assimilation method along with inverse problem techniques using incomplete and complete observational data,so as to determine the variation of position of epilimnion which has influences on SST.

由于温跃层的变化对海表温度的影响，我们以简单的海温模式为例，采用变分同化技术及反问题的技巧，在局部和整体观测资料下，对初、边值条件和模式参数等进行最优估计，确定温跃层的位置及其变化规律。4。

The observational data can only identify an equivalence class of DAGs, so we must perform intervention experiments to determine the directions of reversible edges from experimental data.

然而，仅有观察数据只能识别出DAG的一个等价类，而不能唯一确定其中的一个DAG，因为可反向边的方向不能确定，所以，必须进行干预实验。

He didn't do the rigorous positioning work, the metaphor elicitation with customers, the ethnological and anthropological observational in situ research.

Lastly, microcosmic process of economy cannot be found out thoroughly with experimentalism methods of traditional economics based on observational data, thereby capabilities of explaining and forecasting reality with theories have been reduced.

经济学作为一门单独的科学自从出现以来，已走过了数百年的发展道路，逐步形成了以概念、假设、数据以及数学模型为基础的比较完整的理论体系，并在经济学研究中占据了主流地位。

The effects of friction in surface layer on the structure of front and the frontogenesis in boundary layer, the interaction of orographic disturbance with front, the influence of diabatic process and moist process on the frontogenesis are investigated. Second, the occurrence and development of frontal rainbands have been studied extensively through the observational and theoretical approaches near half-century. However, there are still some problems needing further investigations because of the complication of the precipitation process.

关于锋面降水的产生和分布问题，近半个世纪以来，国内外气象学家进行了大量的观测和理论研究，但是由于问题的复杂性，至今仍有许多问题不清楚，我们利用非静力模式对变形场锋生条件下锋面雨带的发生、发展和演变过程进行了数值模拟和分析。

This doctoral dissertation is composed of several parts: At beginning, the frontal structure, the effects of diabatic heating and orography, the dynamics of frontal circulation and the mesoscale systems associated with front are reviewed. Several problems based on the review are brought forward. First, at present, the semigeostrophic frontogenesis theory is the most appropriate basic framework for the general explanation of the frontogenetic process. However, the comparison between semigeostrophic theory and the observation have revealed some inconsistencies. The newly observational facts increase the inconsistencies.

本博士论文主要由如下几部分组成，首先对锋面结构、地形和非绝热加热对锋的影响、锋生环流及锋面附近中尺度系统动力学问题的历史与现状进行了综述，在此基础上提出需要进行研究的若干问题：(1)、半地转锋生理论直到今天仍是解释锋生过程的最合适的理论框架，但是通过与观测事实比较，人们发现半地转理论不能对许多锋面观测特征给出令人满意的回答，新的观测事实使问题更加突出，这就向人们提出：是什么原因导致半地转理论与实际观测的不符？

By using the continuous observational data of air,radiation and soil from two sites of automatic weather station at Gaize and Shiquanhe on the western Qinghai-Tibet Plateau in the period from October 1997 to November 1998,the diurnal variations of surface albedo in summer and winter are analyzed.

根据1997年10月至1998年11月青藏高原西部改则和狮泉河两个自动气象站连续观测的大气、辐射和土壤资料，在分析高原西部地面反射率冬、夏季日变化特征的基础上，重点研究了地面反射率与土壤和大气若干重要因子(如土壤湿度、土壤温度、空气相对湿度、空气温度)的关系。

Data comparison shows a significant correlation between the TOR and surface ozone data collected at the GAW Lin 誥 n regional background station in the Yangtze Delta region, suggesting that the observational data have regional representativeness.

结果表明，长江三角洲地区对流层 O3柱含量的季节变化与该地区的临安区域大气本底站的地面 O3季节变化有着显著的相关关系，临安站的观测数据具有区域代表性。

Don't get out of the observational habit.

请别抛弃监视性观察习惯。
