2003年发表的题为《液体的脆弱性是否嵌入其玻璃的特性？“，报道了玻璃形成体的结构α松弛的性质已经存在于更快的笼状动力学中。他们的重要发现具有深远的影响的过程比结构的$α $-松弛，不能忽视在解决玻璃化转变问题。从那时起，实验和模拟进行了许多玻璃形成不同的化学和物理结构，发现强连接的$alpha$-松弛不仅与笼动力学，而且与二次松弛的特殊类型，称为JGX $beta$-松弛。一般的结果表明，这些快速过程是不可分割的$α $-松弛，任何试图解决玻璃化转变问题应考虑到这一事实。在本文中给出的连接的例子来阐明的发展和进步，因为鼓舞人心的出版Scopigno等人。
The 2003 seminal paper entitled "Is the Fragility of a Liquid Embedded in the Properties of Its Glass?" by Tullio Scopigno, Giancarlo Ruocco, Francesco Sette, and Giulio Monaco, reported that the properties of the structural $alpha$-relaxation of glass-formers are already present in the faster caged dynamics. Their important discovery has far-reaching implication of the processes faster than the structural $alpha$-relaxation that cannot be ignored in solving the glass transition problem. Since then, experiments and simulations performed on many glass-formers with diverse chemical and physical structures have found strong connections of the $alpha$-relaxation with not only the caged dynamics but also with the secondary relaxation of the special kind, called the JGX $beta$-relaxation. The general results indicate that these fast processes are inseparable from the $alpha$-relaxation, and any attempt to solve the glass transition problem should take account of this fact. Examples of the connections are given in this paper to elucidate the developments and advances made since the inspiring publication of Scopigno et al.
