[目的/意义] 专利引用是一种达成技术扩散效果的行为，研究专利前向引用行为特点是测度技术扩散模式的一个重要视角。[方法/过程] 以石墨烯传感器技术领域为例，对专利的前向引用趋势进行Logistic回归分析，验证技术领域的扩散模型；与相关研究方法与结果进行比较。[结果/结论] 验证了专利前向引用符合Logistic扩散模型，是研究技术扩散的可靠视角；将已有研究结论“某一领域中基础核心专利的前向引用遵循Logistic扩散模型”进一步拓展为“某领域专利的前向引用遵循Logistic扩散模型”。

[Purpose/significance] The patent citation is a kind of behavior that can reveal the pattern of technology diffusion. It is an important research tool to infer the technology diffusion behavior by using the patent forward citations. [Method/process] In this study, we fit the cumulative forward citations to the Logistic model again for Graphene sensor with the optimized experiment method. We analyzed and discussed the differences of the methods and results with the previous two studies, which were held by Hosein Fallah and Elliot Fishman in 2009 and Zhang Xiaoqiang et al. in 2014. [Result/conclusion]It is re-verified that the patent forward citations infer the model of technology diffusion. And a further hypothesis based on the previous studies that the pattern of the forward citations of all the patents within a certain technical field follows the Logistic diffusion model is further confirmed.
