为调节扩散的缺陷浓度；是有效振动频率；为活化能垒.条件相同时,锂离子的扩散由活化能垒决定.第一原理中应用(Nudged elastic band,NEB)方法确定两个稳定含锂结构为点间锂离子扩散的活化能垒,进而判断扩散途径和扩散难易. 双层掺氮的纳米管中的锂离子扩散研究,结果显示氮掺杂的碳纳米管不会改变锂离子的扩散路径,但是扩散能垒从9 eV减少到1 eV,有利于锂离子自由扩散到氮掺杂CNTs,但......
inversion that L- and P-band SAR acquisitions contain much more valuable information about the forest vertical structure and the sub-canopy terrain because of their strong penetration ability, which... baseline design of spaceborne system. Providing the spaceborne platforms, the existing spaceborne SAR sensors are characterized by multi-band and multi-polarization acquisitions, as well as high spatial......
such as the maximum amplitude in the frequency band [28] or the frequency-time domain like the wavelet transform features has been used [29], while some other studies suggest to use new features [30-36......
theory to establish the geological sound field theory. The general process was as follows: due to the narrow band of the infrasound signal, the wave equation was first transformed to the Helmholtz......
