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.   A novel bearing fault diagnosis method based on principal component analysis and BP neural network 会议论文  OAI收割 Changsha, China, November 1-3, 2019 作者:  Sun Y(孙越);  Xu AD(徐皑冬);  Wang K(王锴);  Han XJ(韩晓佳);  Guo HF(郭海丰)   |  收藏  |  浏览/下载：19/0  |  提交时间：2020/06/21 Fault diagnosis  rolling bearing  principal component analysis  wavelet packet energy  high dimensional features   Inhibiting mechanism of small molecule toward the p53-MDM2 interaction: A molecular dynamic exploration 期刊论文  OAI收割 CHEMICAL BIOLOGY & DRUG DESIGN, 2018, 卷号: 92, 期号: 4, 页码: 1763-1777 作者:  Chen, Jianzhong;  Wang, Jinan;  Pang, Laixue   |  收藏  |  浏览/下载：48/0  |  提交时间：2019/01/08 hydrophobic contact scanning  MM-GBSA  p53-MDM2 interaction  principal component analysis  solvated interaction energy   Intercomparison of Three Two-Source Energy Balance Models for Partitioning Evaporation and Transpiration in Semiarid Climates 期刊论文  OAI收割 REMOTE SENSING, 2018, 卷号: 10, 期号: 7, 页码: 20 作者:  Yang, Yongmin;  Qiu, Jianxiu;  Zhang, Renhua;  Huang, Shifeng;  Chen, Sheng   |  收藏  |  浏览/下载：56/0  |  提交时间：2019/05/23 component temperature decomposition  evapotranspiration partitioning  two-source energy balance model   Direct Effect of Dielectric Surface Energy on Carrier Transport in Organic Field-Effect Transistors 期刊论文  OAI收割 ACS APPLIED MATERIALS & INTERFACES, 2018, 卷号: 10, 期号: 18, 页码: 15943-15951 作者:  Zhou, Shujun;  Tang, Qngxin;  Tian, Hongkun;  Zhao, Xiaoli;  Tong, Yanhong   |  收藏  |  浏览/下载：24/0  |  提交时间：2019/04/09 Organic Single Crystal  Field-effect Transistor  Mobility  Dielectric  Surface Energy  Polar Component  Dispersive Component   Analysis of Energy Deposition on Ion Source Components of EAST Neutral Beam Injector 期刊论文  OAI收割 FUSION SCIENCE AND TECHNOLOGY, 2016, 卷号: 70, 期号: 3, 页码: 429-434 作者:  Li, Xiang;  Xu, Yongjian;  Hu, Chundong;  Yu, Ling;  Chen, Yu 收藏  |  浏览/下载：22/0  |  提交时间：2017/07/14 Energy Deposition  Ion Source Component  Neutral Beam Injector   Efficiency evaluation of material and energy flows, a case study of Chinese cities SCI/SSCI论文  OAI收割 2016 作者:  Song T.;  Yang, Z.
