The main achievements of the project are as follows: 1 the hypothesis that a decrease in seed mass causes an increase in mean dispersal distance has been tested based on the experiments of weed dispersal by wind. The experimental results partly support the hypothesis. The results will help farmers to make an optimal strategy of weed control; 2 a statistic method for inferring probabilistic distribution function of a random variable has been developed, by which probabilistic distribution functions of weed species dispersal have been determined; 3 the reproduction structure of Bromus sterilis has been studied; 4 a more complex CA model with 25 neighborhood cells were built, which can simulate spread of a weed population. This work promotes developments in both theory and application of CA models; 5 the "mean law" in weed control has been proposed. Accordingly, the algorism of patch spring may be calibrated; 6 the "patch" and "true patch" have been mathematically defined so that herbicide can be efficiently applied; 7 simulation validates that initial configurations of weed will affect dispersal of its population and strategies of controlling it, or its distribution patterns affect its dispersal progresses.
主要完成的工作和取得的成果有:1)用实验证实了重量较轻的杂草种子并不一定飞得比较重的远,其结果有助于农民制订杂草的优化控制策略;2)发展了一种推断随机变量分布函数的统计方法并用它来获得了几个杂草种的扩散分布函数;3)对杂草Bromus sterilis的繁殖结构进行了研究;4)建立了一个具有25邻的较复杂的能模拟杂草扩散的CA模型,并在理论和应用方面促进了CA模型的发展;5)在杂草控制方面提出了&平均法则&,据此可对按块施药方法进行校正;6)精确地定义了&块&和&真块&以便在杂草控制中能更有效地使用除草剂;7)模拟证实杂草种群的初始配置影响其扩散和控制策略,或者格局影响过程。

Results: The lesion located in the left choana region and left sphenoidal sinus of this case involved the left pharyngeal mucous space, left infratemporal fossa and its adjacent bone structure. CT showed that the rhinoscleroma in granulomatous stage was a soft mass which was irregular in shape, with a well-defined margin, inhomogeneous density and bone destruction. MRI showed heterogeneous hyperintensity on T1WI and isointensity on T2WI with an intermediate heterogeneous enhancement.
结果:病变起源于左侧后鼻孔及左侧蝶窦区,累及左侧咽粘膜间隙、左侧颞下窝及邻近骨质;结合本病例及文献复习,肉芽肿期鼻硬结病CT表现为不规则软组织肿块,轮廓清楚,密度不均匀,可见骨质破坏,残存骨质呈硬化改变;MRI表现为T1WI高信号T2WI等信号影,信号不均匀,增强后中度不均匀强化。

By comparison between SMM HXRBS observation and ground observation of Hα and CaIIK lines, especially through the combined study between SMM HXRBS observation and chromospheric flare models, the results show that: in the initial stage of impulsive phase, there is a correlative relation betweem Hα line intensity and hard X-ray emission; different spike in hard X-ray flux curve represents the burst at different location; the energy taken by non-thermal electron beam is larger than the radiative loss in chromosphere; for the flare studied here, the chromospheric evapporation is explosive; if the chromosphere is in balance between electron beam bombardment and radiative loss, the column mass density at the top of chromospheric flare model can not be taken as measure from the source of electrons and then the total material between the source of electrons and the top of chromosphere can be estimated.
通过一个具体耀斑的SMM HXRBS观测结果与同时基于地面得到的Hα和CaⅡK可见光谱观测结果对比,特别是将硬x谱观测结果与色球半经验模型联立研究,结果显示出:在脉冲相上升段,硬x发射与Hα辐射之间存在对应关系;硬x线光变曲线中不同脉冲爆发分量不太可能起源于同一位置;硬x辐射所反映的高能非热电子总携带能量大于色球总辐射损失;对所研究的耀斑而言,其色球蒸发过程是爆发性的;在详细比较了非热电子色球总沉积和色球辐射损失的基础上,指出半经验模型中色球顶部柱数密度不能看成是从非热电子源度量的,从而估计了色球顶部到非热电子源之间的总物质。
