摘要
19世纪,人类有关语言本质问题的认识,在已有语言工具论、符号论等有关理论继续得以向前发展的同时,又出现了语言世界观说、语言生物机体说,以及语言的本质在于交际等一些新的思想火花。
Using the alternate current impedance spectrum method,the grain boundary effect on the β-boron electrical transport properties under high pressure has been investigated up to 28.3GPa.Both the crystal grain resistance and the grain boundary resistance of β-boron decreased with the pressure,and the grain boundary conduction at 23.9GPa has almost disappeared along with the emergence of the van der Waals forces and the interactions between the grain boundaries.
