Under the first-order approximation of Taylor expansion, the analytic expression for the defect mode frequency is derived, from which the coupling factor is deduced.
利用泰勒展式的一级近似，得到了缺陷模频率的解析表达式，进而得到紧束缚理论中的耦合因子。
By oil immersion coupling. the system can be used to detect near surface defects with focussing probe. find surface cracks with surface wave probe and determine defect size with computerized C-scan.
该装置采用全油浸耦合，用聚束探头检测近表面缺陷，用表面波检测表面裂纹，用计算机化c扫描定量缺陷尺寸。
Clutch slippery inspection: the coupling slips, mainly because the clutch wrap clearance defect.
离合器打滑的检验：离合器打滑，主要是因为离合器握把间隙不足引起的。
The energy-transfer rate from the defect mode to the atoms is dependent on the ration of the RDDI coefficient to the atom-photon coupling coefficient.
结果表明 ，当多数原子处在基态且无缺陷模时 ，RDDI的集体作用不能使能量从激发态原子传递到非激发态原子 ；
