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.   Segmenting Microscopy Images of Multi-Well Plates Based on Image Contrast 期刊论文  OAI收割 MICROSCOPY AND MICROANALYSIS, 2017, 卷号: 23, 期号: 5, 页码: 932-937 作者:  Chen, Weiyang;  Li, Weiwei;  Dong, Xiangjun;  Liao, Bo;  Flavel, Matthew   |  收藏  |  浏览/下载：13/0  |  提交时间：2020/12/09 microscopy image  uneven illumination  bright field  multi-well plate  image segmentation   Segmenting Microscopy Images of Multi-Well Plates Based on Image Contrast 期刊论文  OAI收割 MICROSCOPY AND MICROANALYSIS, 2017, 卷号: 23, 期号: 5, 页码: 932-937 作者:  Chen, Weiyang;  Li, Weiwei;  Dong, Xiangjun;  Liao, Bo;  Flavel, Matthew   |  收藏  |  浏览/下载：17/0  |  提交时间：2020/12/09 microscopy image  uneven illumination  bright field  multi-well plate  image segmentation   Numerical simulation of electricity generation potential from fractured granite reservoir through vertical wells at Yangbajing geothermal field 期刊论文  OAI收割 energy, 2016, 卷号: 103, 页码: 290-304 作者:  Zeng, Yu-chao;  Zhan, Jie-min;  Wu, Neng-you;  Luo, Ying-ying;  Cai, Wen-hao 收藏  |  浏览/下载：38/0  |  提交时间：2016/12/05 Vertical well  Yangbajing geothermal field  Fractured granite reservoir  Heat production  Electric power   Numerical simulation of electricity generation potential from fractured granite reservoir through a single horizontal well at Yangbajing geothermal field 期刊论文  OAI收割 energy, 2014, 卷号: 65, 页码: 472-487 作者:  Zeng, Yu-Chao;  Wu, Neng-You;  Su, Zheng;  Hu, Jian 收藏  |  浏览/下载：20/0  |  提交时间：2016/11/03 Single horizontal well  Electricity generation potential  Fractured granite reservoir  Water mining  Yangbajing geothermal field   IMPACT OF THE SOUTH-TO-NORTH WATER DIVERSION PROJECT ON GROUNDWATER RESOURCES: A CASE STUDY IN PINGGU BASIN, BEIJING, CHINA 期刊论文  OAI收割 ENVIRONMENTAL ENGINEERING AND MANAGEMENT JOURNAL, 2013, 卷号: 12, 期号: 11, 页码: 2239-2247 作者:  Xu, Haizhen;  Li, Ming;  Li, Guomin;  Zhang, Shouquan;  Dong, Yanhui   |  收藏  |  浏览/下载：18/0  |  提交时间：2017/12/22 Groundwater  Numerical Model  South-to-north Water Diversion Project  Sustainability  Well Field   Effects of Measurement Method, Scale, and Landscape Features on Variability of Saturated Hydraulic Conductivity SCI/SSCI论文  OAI收割 2013 Hu W.; Shao M.
