在ＣＶＤ反应器中超细粒子粒度分布控制模型化研究的基础上，进一步探讨了ＣＶＤ反应器中超细粒子的形成过程，详细分析了超细粒子的烧结和晶型转变，以此为基础建立了晶体组成及含量的控制模型，并进行了晶体组成及含量的模型化研究。从方法论角度分析，晶体组成及含量的模型化研究方法和粒子粒度分布的研究方法一致，但前者以后老的研究为基础，体现了序贯研究的基本思想。 Based on the modeling of particle size distribution control of ultrafine particles in CVD reactor, the formation process of ultrafine particles in CVD reactor was further discussed, and the sintering and transformation of ultrafine particles were analyzed in detail. Based on this, The crystal composition and content of the control model, and the crystal composition and content of the model. From a methodological point of view, the method of modeling the composition and content of crystals is consistent with that of particle size distribution. However, the former is based on old research and reflects the basic idea of ​​sequential research.
