传统对数值模式模拟效果的评估主要是基于均值、趋势、概率密度分布、极值等方面的特征比较模拟要素与观测值的差异或是通过分析模拟值与观测值之间的相关性来定量判断.这类评估方法主要考虑了模式模拟结果与观测资料在统计上的差异,缺乏对两者在动力学特征上的比较.鉴于此,本文基于气象观测资料演变过程中所展现的长程相关性特征,利用去趋势波动分析方法对观测资料和模式模拟数据进行标度分析,研究模式模拟结果是否具有类似于观测资料中的长程相关性特征,进而通过比较观测资料和模式模拟结果的标度指数,从大气演变的内在动力学特征上对模式模拟性能进行评估.本文对北京气候中心气候系统模式对中国地表气温的模拟性能进行了评估,结果表明,该模式能够较好地反映出中国区域气温要素的长程相关性特征,对东北、西北中东部、江淮、江南东部等地模拟效果较好,但对于青藏高原地区及西北大部、华北、黄淮等地的模拟效果相对较差,其中对青藏高原地区和西北西部的模拟效果最差.
The traditional evaluation of simulation perfomance for numerical model is based on the differences in average, trend, probability density distribution, extreme value, variance and self-correlation between observational data and the simulated data by numerical model. These evaluation methods mainly depend on the comparison of statistical difference between the simulation and observation, but ignore the comparison in the dynamical characteristics of climate system. In view of this, in the present paper we use detrended fluctuation analysis (DFA) method to analyze the scaling characteristics of daily temperature from observational data and the corresponding simulated data by climate model, and investigate whether the long-range correlation of meteorological elements can exist in the simulated data of climate model. If so, we can assess the performance of climate model based on the comparison of scaling index between the observational data and the simulated data. As an example,

用聚丙烯代替悬浮颗粒，采用数值模拟的方法对流场进行了深入研究。首先通过试验分析，取得了满意的数值模拟效果后，采用标准湍流模型对偏心搅拌流场进行模拟。然后针对不同模拟工况进行试验验证比较，分析不同的偏心程度对速度分布、湍动能大小、物料(聚丙烯)混合效果以及混合时间的影响。研究表明，偏心率为0·22左右，浸入深度在容器高度的35%时，流场分布比较均匀，死区较小，更有利于物料混合，搅拌效果最好。
The polypropylene was used as suspended particle, and numeral simulation was performed to investigate the effects of differentstirring styles. The model was firstexamined based on the CFD simulation and experiments to obtain the reasonable results, and then the k-E unsteady model was adopted to simulate the flowing field of eccentric agitation. The simulated results were verified with the experimental results to analyze the impacts of differenteccentric degrees on the velocity distribution, tur-bulence kinetic energy, and mixing effects and time of polypropylene. The results showed thatthe offsetratio is about0· 22, and when the immersion depth is 35% of the bottle height, the flowing field is well distributed with small“ death zone”, which is beneficial to the mixing of polypropylene.

当前，我国法学专业高等教育体系中的模拟审判实践教学“表演性”成分过度，仿真性程度不足。此种教学效果不利于学生综合实践能力、独立思考与决断能力的培养，同时也模糊了模拟审判个体角色责任范围的界线。造成这种教学效果的原因是多方面的。我国各高校法学院系教学管理部门应提高对模拟审判教学仿真性程度的关注度、应建立模拟审判仿真性程度考核的明确标准，同时，应打破模拟审判人员组成上的传统的班级成员组合模式，以此来降低模拟审判教学的“表演性”成分，增强其仿真性比例。
At present, the practical teaching of mock trial in the higher education of law major has excessive performance and insufficient simulation, which is not good for the cultivation of comprehensive practical ability and independent thinking or deciding ability for students, and meanwhile, which also makes the responsibility scope of personal role played in the mock trial more indistinct. The teaching administrating department of law school in China ’s university should pay more attentions to the simulation degree of mock trial teaching, and should establish clear standards to check the simulation degree, in the mean time, should break up the traditional organization method of classmates from the same class that gets the group of mock trial, to reduce the degree of performance and enhance the degree of simulation in mock trial teaching.
