祁连山北坡中段森林植被梯度分析及环境解释 - It is found that the mesoscale mountain has significant influence on the location and intensity of the heavy rain area , and the bell - mouthed area and the riverway area of xichang are favorable to the occurrence and development of mesoscale disturbance and heavy rain
地形梯度分析表明，西昌地区所处的河谷地形和场区所处喇叭口小地形，有利于中小尺度气压扰动的发生、发展和暴雨的产生，当地形梯度减弱时，降水量相应减弱。 - So if dca combines with classified methods , the ordination effect on samples and species is better than that of dcca and cca . 2 . fso study on plant communities : we applly fuzzy set ordination ( fso ) to analyze the environmental factors and vegetation data
植物群落的模糊数学排序研究：运用模糊数学排序对样地的环境因子和植被数据进行了直接梯度分析，结合twinspan分类结果，与dcca比较，模糊数学排序直观的得出了环境因子和植物群落间的关系，分辨率较高。 - The coupled turbulent flow field and temperature field are simulated by finite element method ; the influence of casting speed on the turbulent flow field and temperature field in the melting bath and the interaction between those two field are analyzed ; the variation tendency of the heat flux intensity between the melting bath and casting roll and law of variation with changes of casting speed in the process of solidification are given ; a comparison between the simulation results and experimental results demonstrates their good agreement ; and the mechanism of the heat flux variation is identified by analysis on the temporature gradient and development of solidification within the melting bath and its influence on the variation of the heat flux intensity
采用有限元法模拟了双辊铸轧不锈钢过程的流热耦合问题;分析了铸轧速度对熔池内流场、温度场的影响以及流场与温度场之间的相互影响;给出了凝固过程中熔池与铸轧辊之间的热流密度变化趋势及随铸轧速度的变化规律,并把此模拟的结果与试验的结果相比较,吻合较好;通过熔池内温度场及温度梯度分析了熔池内凝固的发展及其对热流密度变化的影响。 - 3 eight communities are identified by gradient analysis in desert - oasis ecotone , and species are divided into 5 ecological groups . dca ordination is superior to cca and dcca . variation of vegetation explained by environmental and spatial factors reaches 23 . 4 % ; among these the species matrix explained by non - spatial soil factors account for up to 11 . 5 % of variation , spatial variation that is not shared by soil factors explains up to 11 . 6 % , their interaction explains up to 0 . 3 %
3 、通过梯度分析，阜康荒漠绿洲过渡带群落可分为8个类型，物种可分成5个生态类型； dca排序效果优于cca和dcca ；土壤和空间因子解释了植被分异的23 . 4 ，其中土壤因子占11 . 5 ，空间因子占11 . 6 ，二者交互作用占0 . 3 。
