Apical aneurysms varied considerably in size (maximum dimension, 10 to 66 mm), were dyskinetic/akinetic with thin rims, and were associated with transmural myocardial scarring identified by late gadolinium enhancement cardiovascular magnetic resonance.

Analytical formulae are presented for the first time to describe the shift in the resonance wavelength of LPG in response to etching of the fiber cladding or a change in the external refractive index. The accuracy of the formula is confirmed by comparision with numerical simulations and experimental results. We demonstrated that the resonance wavelengths of an etched LPG are more sensitive refractive index than those of an unetched grating. The bending properties of long period fiber grating written in different type fiber are studied experimentally. The transmission peaks and the central wavelength of LPG change with the bending of the fiber. A new peak appears at the shorter wavelength when the fiber is being bent. The changes of the peaks are different for different photosensitive fiber. Those properties have broad application foreground in fiber sensors and tunable filters.

分别从理论和实验上对长周期光栅的折射率特性以及光纤包层半径对长周期光栅特性的影响进行了研究，首次给出了描述光纤包层半径腐蚀和外界折射率改变与长周期光栅共振波长关系的理论表达式，实验与理论和数据模拟的结果很好符合，利用腐蚀光纤包层的方法可以有效地提高LPG的折射率灵敏度；对不同光纤中写入的长周期光栅的弯曲特性进行了实验研究，LPG的透射峰形状及其中心波长随光纤弯曲而发生变化，并且随着弯曲将在短波方向出现新的透射峰，其透射峰的变化规律因所用光敏光纤的不同而不同，这一特性在光纤传感和可调谐滤波器方面有重要的应用前景。

Taking the development platform of HVDC power transmission for example, the calculation result of impedance-frequency characteristic of traditional line commutated converter and that of FCC are compared. Simulation results show that the impact of impedance-frequency characteristic of converter on the resonance frequency of AC system is not negligible, and FCC can enhance the strength of AC system in a certain extent, improve system stability and effectively reduce AC equivalent impedance under resonance frequency, thus the harmonic instability of HVDC power transmission system can be avoided.

以直流输电开发平台为例，对传统电网换相换流器(line commutated converter，LCC)与FCC的阻抗频率特性计算结果进行对比，仿真结果表明换流器的阻抗频率特性对交流系统的谐振频率有着不可忽略的作用，FCC在一定程度上提高了交流系统强度，改善了系统稳定性，有效降低了系统谐振频率下的交流等值阻抗，从而更好避免直流输电系统谐波不稳定现象的发生。
