分子结构与其性能间的关系,是化学领域一个带有根本性的基础理论课题,多年来,许多研究者从不同角度探讨了这一课题。对于烷烃同分异构体的密度与其分子结构之间的关系,由于理论研究十分困难,因而文献很少有系 The relationship between the molecular structure and its properties is a fundamental fundamental theoretical issue in the field of chemistry. Over the years, many researchers have explored this issue from different perspectives. There is little literature on the relationship between the density of alkane isomers and its molecular structure due to the difficulty of theoretical studies
