One of the great discoveries of the study is that the MSC can be used to analyze and describe the complex reactions that both phase transformation and sintering happened at same time. In addition, using both our five-parameter S-curve fitting and German's three-parameter curve fitting lead to very similar results and values of Qa. Most importantly, we cannot find satisfactory data to support the hypothesis that Qa varies linearly either with particle diameter or with initial porosity of the samples.

在利用主导烧结曲线模型分析六组实验数据过程中，发现主导烧结曲线具有拟合烧结与相变同时发生之能力，此拟合曲线中包含了四个反应，包括anatase与anatase的烧结、anatase与rutile的烧结、rutile与rutile的烧结还有anatase的相变，此四种不同的反应竟然可以只由一条主导烧结曲线描述其变化，是本研究重要的发现。
