At the temperature as low as that at which the monomer cannot diffuse in large scale,adatom nucleation and island formation depends on the increase of adatom density.With the increase of temperature,the film growth mode depends on the competition between in-plane diffusion and inter-layer diffusion of monomers.

当薄膜生长温度低于单原子的扩散温度时，表面原子的成核和表面岛的生长主要是由沉积原子的空间随机性和表面原子密度增加而决定的，随着薄膜生长温度的提高，薄膜的生长模式则取决于单原子的层内扩散和层间扩散的竞争。

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。

Meanwhile, by modeling the sewage diffusion, it is found that the range of the Changjiang Estuary sewage diffusion area can reach the East Chongming Bank, the Deep water Channel, and the Nanhui Bank, while the COD concentration near Meimaosha is especially high so that the sewage diffusion constitutes a threat to the water quality of Meimaosha area.

同时，通过对污染物扩散的数值模拟，本文发现长江口污染物的扩散范围能够到达崇明东滩、深水航道和南汇边滩，而没冒沙附近区域的COD浓度更是尤其地高，所以污染物扩散对没冒沙地区的水质也形成了一定的威胁。

Secondly, this paper set up the diffusion model of innovation incorporating price, advertising and distribution, and given the optimal diffusion equation and characterized qualitatively optimum price, advertising and distribution. Furthermore, it studied the ratio relations among the advertising elasticity of demand and the price elasticity of demand and the distribution elasticity of demand. Finally studied the influence of marketing mix variables to the technology diffusion.

然后建立了含商品定价、广告费用和销售费用等的技术创新扩散模型，给出了扩散最优方程和商品价格、广告费用和销售费用的最优曲线，进一步地，本文分析了广告费用对需求的弹性、商品定价对需求的弹性以及销售费用对需求的弹性之间的比例关系，探讨了这些外部市场变量对创新扩散的影响。

The improved model possesses band-pass filer characteristic, diffuses processing stability and satisfies the max-min principle. The simulation results show that the median filter is only proper for outlies noise and removes the thin line and corners of image. The linear filter extends or blurs the boundary of image. The anisotropic diffusion removes random noise effectively, but it brings about illusive edge and back diffusion for outlies noise. The improved model that possesses both median filter characteristics and anisotropic diffusion capability is proper for various mixed noise and can sufficiently protect the detailed characteristic such as corner, thin line and edge.

研究结果表明：中值滤波作为一种经典的非线性滤波方法仅适合于&飞点&噪声的滤波并引起图像的角点、线条损失，线性滤波扩大或使图像边界范围模糊；传统的各向异性扩散能对随机噪声有效地压制，但对&飞点&噪声会产生虚假的边缘甚至反扩散，而改进模型既具有中值滤波的特性又具有传统各向异性扩散的性能，适合于平滑不同强度与形状的混合噪声，并对角点、线条、边缘等细节信息提供足够保护。
