It is shown that GPS/PWV data with an time interval of 30 minutes reflected spatial and temporal changes of atmospheric vapor intuitionally and duly, the features of GPS/PWV changes had corresponding relations with the precipitation, the divergence of GPS/PWV showed the distributions of the convergence and divergence of atmospheric vapor.

分析还表明:每30min一次的GPS/Pwv资料能直观地、及时地反映大气中水汽的时间变化和空间变化;GPS/Pwv资料随时间的演变特征与降水有较好的对应关系;GPS/Pwv的散度资料可以反映大气中水汽的辐合、辐散分布情况。

The photopolymerization led to stable latices and they were obtained with neither coagulation during synthesis nor destabilization over time. It was found that the obtained MMA homopolymers exhibited relatively narrow molecular weight distributions(PDI=1.27—1.36), which was characterized by GPC. The plots of number-average molecular weight vs. conversion and ln([M0]/) vs. time were linear respectively, indicating that the reaction was a controlled/living free radical polymerization.

结果表明,该细乳液体系非常稳定,在整个聚合过程中即没有絮凝物产生,也没有沉淀析出,获得了良好的ln([M0]/)与时间、数均分子量与转化率之间的线性动力学关系,并且在整个聚合反应过程中MMA均聚物的分子量分布比较窄,其多分散性指数较低(PDI=1.27~1.36),具有明显的活性聚合特征。

For many instruments, the distributions of their real market returns are leptokurtic and fat tails, thus a correction factor was introduced to improve the precision of VaR.

考虑到实际的资产价格分布的尖峰厚尾性,引入了正态修正因子θ,以改进VaR的风险评估效果。

粗壮的植株非常类似于Lysimachia hemsleyi Franchet;不过,他们的分布和花时代不同。

We drawn the predicted surface maps with the Ordinary Kriging method and illustrated in the time order to provide a visible presentation of the spatio-temporal distributions. By analyzing those maps, we found that the spatial distribution of spiders in the paddy field was similar to that of macropterous SBPH and larval SBPH, and was more similar to larval SBPH, and showed an obvious pursuing phenomenon between them, while the pursuing had a close relationship with the temporal dynamics of SBPH number. But the pursuing phenomenon was complex and influenced by factors such as the weather, the environmental conditions in paddy fields, other enemies of SBPH and other foods of spiders.

用普通克立格方法作出空间分布图,在时间序列上进行比较分析,得出稻田蜘蛛与灰飞虱成若虫的空间分布均有相似性,尤其与若虫相似性更强,表现出比较明显的空间跟随现象,且空间跟随现象与灰飞虱虫量的消长有密切的关系,但是由于天气、稻田环境、灰飞虱其他天敌以及蜘蛛其他猎物的存在等因素的影响使得其空间跟随又有着相当的复杂性。

Distributions of neutral and zwitterionic microspecies reached the maximum at isoelectric point , with the latter being predominant.
