中文摘要：

利用微积分方法定量地对技术创新扩散的模型和发展规律进行了探讨，揭示了技术创新扩散发展变化的动力学特征。并利用该扩散模型对RP技术的推广应用进行了研究，建立了RP技术扩散模型，根据该模型对RP技术的推广情况做出了预测，这对RP技术在我国的推广应用具有一定的参考价值。

英文摘要：

The model and change rule the technical innovation diffusion process has been approached by means of calculus method, revealed the dynamic characteristics of the change rule of the innovation diffusion. Based on the diffusion model, the diffusion and application of RP has been researched and the diffusion model of RP has been built. With this model we can estimate the application of the diffusion of RP technology, and gain the scientific decisions which provide us with consultant value.
