查询词典 observations

While indirect assimilation experiment is better than that of non-assimilation one in rainfall center, the former appears positive role.2 Radar observations direct assimilation experiments: By means of ARPS-3DVar and ADAS (ARPS Data Analysis/Assimilation System), CINRAD observations are assimilated only with NCEP reanalysis data for the forecast of rainstorm. Results show that meteorological element fields are improved observably by assimilation experiments.

以面向雷电预报的雷达、卫星遥感资料同化及其应用为研究目的，利用NCEP资料、新一代多普勒雷达网、FY2C气象卫星、闪电定位仪网、自动气象站等观测资料的诊断、同化模拟以及理论分析等方法，对气象遥感资料的同化设计及其在雷暴天气条件下雷电预测方面的应用进行了综合研究和初步分析。

The incorporated model is evaluated by simulation results of two different building aerodynamical scheme in southeast region of Beijing area, which are building drag scheme and aerodynamical urban canopy scheme. The conclusions are drawn by the comparisons between the simulation results of the wind speed and the observations of the automatic weather stations in the urban areas: the simulated results of incorporated model are more in reasonable agreement with the observations than that of building drag scheme, and the diurnal trend of that is more agreement with observations.

采用建筑物拖曳法和建筑物动力冠层方案两种不同建筑物动力学处理方法对北京地区东南部进行模拟，通过城市地区水平风速的模拟结果与自动气象站实测资料对比发现模拟结果与实测相当吻合，建筑物动力冠层方案的引入能够更好地实施对城市地区的水平风速分布的数值模拟。

Considering complicated conditions of the coastal dynamic environment, sediment dynamics, and together with the immature sediment itself, the predicted results will be somewhat limited if only with numerical model. So, in order to obtain microcosmic quantitative assessment and macroscopically understanding, numerical model is combined with field observations in the thesis. Firstly, the tidal current, SSC distribution, benthal deposited materials were basically analyzed by field observations. Then, the tidal current, SSC distribution, and the erosion and accumulation of the seabed were simulated with the numerical model of ECOMSED.

但由于海岸动力环境多变，泥沙运动复杂，加之泥沙问题本身的复杂性，如仅用数学模型，其预测结果将受到一定的限制，故本文采用实测调查与数学模型计算相结合的方法，宏观把握，微观量化，在掌握岚山港西突堤工程所在海域潮流、悬沙量分布、表层底质沉积物类型及特点基本态势的基础上，紧扣开发工程可能引起潮流场变化，分析工程后悬沙量、海底冲淤变化及其空间分布，进而建立潮流作用下的泥沙输运数学模型，首先比较好地模拟目前岚山港西突堤工程附近海域的潮流场和悬沙场，然后预测海湾沿岸可能引起的冲淤强度变化和冲淤区域的空间分布。

This expansion is well supported by observations and is one of the foundations of the Big Bang Model. In the late 90's, observations of supernova[2] determined that not only is the universe expanding, it is expanding at an increasing rate.

宇宙的膨胀得到了观测的很好的支持，并且是大爆炸模型的基石之一。90年代后期，超新星的观测指出宇宙不仅在膨胀，而且在加速膨胀。

Probability The chance that a given event will occur, or that over a series of observations a particular kind of observation will occur regularly as a given proportion of the total number of observations.

概率：指某给定事件即将发生的机率，或经过一系列观察后，某些特定的观察规律性出现的可能性。

Based on the criterion that the volume of estimated parameter's joint confidence region should be minimum, which is a sequential experimental design norm for optimal parameter estimation proposed by Box and Lucas, the observations for the adsorption of n -decane on 5 A molecular sieves were determined sequentially, and it is found that the observations should b.

根据Box和Lucas所提出的使待估参数联合置信域的容积趋于最小的参数估算的序贯实验设计准则，推导得出了正葵烷吸附等温线实验观测点的安排原则，发现对于一元线性模型，实验观测点应安排在可操作区的两端。
