Thirdly, a model of spatial diffusion, which is based on the theory of stochastic process, was presented.Then, an analysis method of equiprobable curve of diffusion and some simulations were provided. 运用随机过程理论与方法建立技术创新空间扩散的数学模型，并提出等扩散概率曲线分析方法，对技术创新空间扩散进行了模拟；
a unit of measurement of information (from Binary+digIT); the amount of information in a system having two equiprobable states 信息单位（二进制数字IT）
a unit of measurement of information (from Binary+digIT); the amount of information in a system having two equiprobable states. 信息单位（二进制数字IT）。
a unit of measurement of information (from Binary+digIT);the amount of information in a system having two equiprobable states. 将十六进制转换成二进制，二进制转换成十进制，等等。
