The strain sensitivitycharacteristic of long-period fibre grating (LPFG) was studied by coupled-mode theory and the strain sensitivity analytic equation of the resonant wavelength was deduced.
The structural dynamic characteristicsensitivity is widely applied to modification of the dynamic structure and the diagnose trouble.
结构动特性灵敏度在动力学结构修改和故障诊断中被广泛地应用。

It utilizes the characteristic of sensitivity to initialization and indeterminism to contrail, so chaotic property determines the performance of chaotic sequence.
