摘要 报道一个实时在线答疑教学系统的定量动力学模型。通过对此模型的分析,研究同步式答疑教学在远程教育中的可行性。可以预期这个模型的进一步修正和完备,将展示更加丰富的复杂行为。 This article reports a quantitative dynamical model of a real-time network-connected system for question answering. Through the analysis of the model, one may study the feasibility of the in-phase question-answering teaching system in the distance education. It can be expected that the model will be further improved and consummated so as to perform even richer complicated behaviors.
