About 1000 d after the SRT, the X-ray luminosity of the associated pulsar wind nebula (PWN) was found to brighten by $32\pm 8{{\ \rm per\ cent}}$. After the SRT, the braking index n of PSR B0540-69 changes from n = 2.12 to 0.03 and then keeps this value for about five years before rising to n = 0.9 in the following years. We find that most of the current models have difficulties in explaining the measured braking index. One exceptive model of the braking index evolution is the increasing dipole magnetic field of PSR B0540-69. We suggest that the field increase may result from some instabilities within the pulsar core that enhance the poloidal component at the price of toroidal component of the magnetic field. The increasing dipole magnetic field will result in the X-ray brightening of the PWN. We fit the PWN X-ray light curve by two models: one assumes a constant magnetic field within the PWN during the brightening and the other assumes an enhanced magnetic field proportional to the energy density of the PWN. It appears that the two models fit the data well, though the later model seems to fit the data a bit better. This provides marginal observational evidence that magnetic field in the PWN is generated by the termination shock. Future high-quality and high-cadence data are required to draw a solid conclusion.   Characteristics and origin of deep earthquake clusters beneath Northwest Pacific and Tonga subduction zone 期刊论文  OAI收割 CHINESE JOURNAL OF GEOPHYSICS-CHINESE EDITION, 2019, 卷号: 62, 期号: 8, 页码: 3004-3016 作者:  Hu Gui;  Li Juan;  Han GuangJie   |  收藏  |  浏览/下载：79/0  |  提交时间：2019/10/14 Deep earthquake  Cluster  b value  Slab buckling  Northwest Pacific subduction zone  Tonga subduction zone   Fracture monitoring and reservoir evaluation by micro-seismic method 期刊论文  OAI收割 CHINESE JOURNAL OF GEOPHYSICS-CHINESE EDITION, 2019, 卷号: 62, 期号: 2, 页码: 707-719 作者:  Li Zheng;  Chang Xu;  Yao ZhenXing;  Wang Yibo   |  收藏  |  浏览/下载：53/0  |  提交时间：2019/03/21 Micro-seismic  Source parameter  b-value  Fracture interpretation  Reservoir evaluation   Acoustic emission characteristics of pre-cracked specimens under biaxial compression 期刊论文  OAI收割 JOURNAL OF GEOPHYSICS AND ENGINEERING, 2019, 卷号: 16, 期号: 6, 页码: 1164-1177 作者:  Liu, Xuewei;  Liu, Quansheng;  Liu, Bin;  Liu, Qi   |  收藏  |  浏览/下载：25/0  |  提交时间：2020/04/08 acoustic emission  rock-like material  AE energy  b-value  biaxial compression
