影响球粒状结构形成的热力学因素是成膜温度，随着成膜温度的降低，有更多的高分子链段形成球粒状结构；

The thermodynamic factor affecting the nodule formation is the membrane formation temperature ; with decrease of membrane formation temperature , more chain segments are able to form nodular structures ;

溶剂脱离成膜体系的速率是影响球粒状结构形成的主要动力学因素，对于致密膜，溶剂脱离体系速率越快，球粒的直径越小。

Evaporation rate of solvent is the major kinetic factor affecting the nodule formation ; for the formation of dense membranes , with the increase of evaporation rate , average diameters of the nodules tend to decrease .

不同类型碳质球粒陨石基质的结构和成分存在显著差异，同时单个陨石基质的成分分布也极不均匀，这表明早期太阳星云的成分是不均一的。

The significant differences of structure and composition in the different carbonaceous chondrite matrix and even the heterogeneous chemical composition in a single meteorite matrix suggest that the early solar nebula is highly heterogeneous in composition .
