摘要
应用非均质空间各向同性技术创新扩散模型以及随机游动理论[1],对技术创新在轴向以及轴间域元扩散过程进行了分析,构造了扩散轴正交和非正交两种情况下非均质空间多源各向异性扩散随机模型.同时,进一步分析了技术创新空间扩散的动态过程,构造了动态空间扩散随机模型.
:Basing on the isotropic diffusion model[1] and the random wa lk model of diffusion media, the authors constructed the multiple-sour ces model the anisotropic model of spatial diffusion of technological innovation in heterogeneous field by analyzing the diffusion axes and the points closed by axes.The diffusion model consists of two equation s, one describes the condition that the axes are orthogonal, the other not vertical. At the same time, the dynamic diffusion process were di scussed and a dynamic model was given.
