| 1 | Impending HRT wave precursors to the Wenchuan M_s8.0 earthquake and methods of earthquake impending prediction by using HRT wave显示文摘We deployed four geo-electric monitoring stations in Sichuan and Yunnan provinces from 2004, using the new generation of equipment (PS-100) and technologies to capture the HRT wave earthquake precursor. Before the Wenchuan Ms8.0 earthquake, we recorded the HRT wave precursor at the only operating station in Hongge (HG, Δ=465 km) and found that significant impending signal had been recorded at the station in the early morning ( 0―5 am) of 12th of May, 2008. The precursor for this earthquake is consistent with precursors recorded for other strong earthquakes. The measured physical properties (geo-resistivity and telluric-current) show tidal wave period oscillations from several days to several months before the earthquakes and the amplitude of such HT oscillation increases significantly towards the occurrence of an earthquake. These HT and RT waves from the epicenter have a causal relationship with the earthquakes that happened several days later. The arrival time of two RT waves is proportional to the distance from the station to the epicenter. The estimated natural decay of the amplitude is correlated with the natural period (T0) of the earthquake fault, which is proportional to the fault length. From this relationship, we can predict the earthquake magnitude. For magnitude 6―9 earthquakes, the natural period is about 1―6 hours. Such oscillation comes from the epicenter area and they can propagate several thousand kilometers in the Earth's crust. Before a strong earthquake in the shallow crust, the conductive pore fluid will experience major changes before the fault rapture. Such fluid change will emit an oscillation in the pore fluid pressure. This is the mechanism for the HRT wave generation. Since the China Earthquake Administration funded the HRT wave short-term earth-quake prediction project in 2003, the first record of HRT precursor wave has been recorded from the 2004-12-26 Sumatra Mw9.0 earthquake with the largest epicentre distance Δ=2900 km. Thereafter, we have captured HRT waves from more than twenty strong earthquakes, which are well-matched and show repeatability, consistency and regularity. All our observation with the HRT waves demonstrate that HRT wave precursors to earthquakes indeed exist. Strong earthquakes can be predicted and short-term and impending earthquake prediction is achievable in the very near future. From all the observations, including the ones at HG station from Wenchuan Ms8.0 earthquake, we conclude that using HRT wave to predict earthquakes is feasible. | QIAN FuYe ZHAO BiRu QIAN Wei ZHAO Jian HE ShiGen ZHANG HongKui LI ShiYu LI ShaoKun YAN GuLiang WANG ChengMin SUN ZhenKai ZHANG DongNing LU Jun ZHANG Ping YANG GuoJun SUN JiaLin GUO ChunSheng TANG YuXiong XU JianMing XIA KunTao JU Hang YIN BangHong LI Ming YANG DongSheng QI WeiLuo HE TaiMing GUAN HuaPing ZHAO YuLin | 2009 | Science China Earth Sciences2009，52，10： | 8 |
| 2 | Durable and Flexible Bio-assembled RGO-BC/BC Bilayer Electrodes for Pressure Sensing显示文摘The new generation of electronics tends to be well-performed,facile and environmentally friendly.Here,we report a bio-assembled sensitive pressure senor based on reduced graphene oxide-bacterial cellulose/bacterial cellulose(RGO-BC/BC)bilayer films,integrated by bacteria in one step.The advantage of this integration is that there is strong nanofiber connection between the conductive RGO-BC and insulative highly compressible porous BC layer,which confers RGO-BC/BC film electrode with good robustness,tailorability,flexibility and wearability.Without extra bonding-interface or postprocessing,the RGO-BC/BC bilayer films could be directly assembled into pressure sensing devices.Ascribed from the good reversible compressibility of the BC layer and incorporated bilayer structure,the pressure sensor performs good sensitivity and excellent durability and bending stability.The facile sensitive capacitive sensor could monitor the human hand or finger motion in real time.The sensing array is able to detect the spatial distribution of pressure mounted in the flat plane as well as curved surface of human body,succeeding in the correction of human walking posture for health care.The e-skins are potential in wearable electronics,artificial intelligence,soft robots,healthcare etc. | Fangyi Guan Zhiliang Han Mengtian Jin Zhuotong Wu Ye Chen Shiyan Chen Huaping Wang | 2021 | Advanced Fiber Materials2021，3，2： | 2 |

| 4 | ZnS/Bacterial Cellulose/Epoxy Resin(ZnS/BC/E56) Nanocomposites with Good Transparency and Flexibility显示文摘ZnS/bacterial cellulose/epoxy resin(ZnS/BC/E56) nanocomposites with good transparency and flexibility were prepared and characterized.When the precursor Zn^(2+) concentrations were not more than 1 wt%,the size of the introduced ZnS nanoparticles was smaller than 50 nm and the distribution was homogeneous within the composites.Under the condition,outstanding transmittance more than 70%in the visible light was obtained.By incorporation of ZnS nanoparticles with excellent thermo-optic stability to the composites,the thermo-optic coefficient was obviously increased from-361×10^(-6) to-310×10^(-6)K^(-1).The good flexibility,optical and mechanical properties endow the nanocomposites potential applications in the flexible optoelectronic materials. | Fangyi Guan Shiyan Chen Jingjing Yao Weili Zheng Huaping Wang | 2016 | Journal of Materials Science & Technology2016，32，2： | 1 |

| 6 | Analysis and Study on the Change of the Observed Geo-electric Field Data at Lhasa Geomagnetic Station before and after the Nepal MS8.1 Earthquake显示文摘In this paper,the main purpose is to analyze and research the characteristics of the geoelectric field observed data with a long time span and large amplitude abnormal change,at the Lhasa geomagnetic station( hereafter referred to as 'Lhasa station '),before and after the Nepal M_S8. 1 strong earthquake,which occurred on April 25,2015. Based on the observation conditions,the observation system,and the observed data of Lhasa station preliminary discussed,the main characteristics of the abnormal change and evolution process are analyzed and studied,using the following two methods; the 'synthesis energy accumulation'and the 'power as MSA spectrum'analysis,from the two aspects of the'Time Domain'and'Frequency Domain. 'The results show that the abnormal change of the geo-electric field observation of Lhasa station experienced a development stage following the process of 'trend change- disturbance change- earthquake period-recovery period',and an evolution process of 'low frequency change- high frequency change- smooth change- high frequency change ',before and after the Nepal M_S8. 1strong earthquake. Comprehensive analysis shows that the variation characteristics and evolution process of the geo-electric field at Lhasa station are basically consistent with the results of the relevant mechanism and phenomenon research. So far,this is valuable information with certain objectivity,which is typical and representative to reflect the whole process of the gestation, occurrence and complete development of such strongearthquakes. | Xi Jilou Guan Huaping Liu Chao Zhuang Nan Guan Xinying Yang Xiaoming Zhang Zhiguo Ci Zhuoga Kelsang Drolma Ma Aiming | 2016 | Earthquake Research in China2016，30，4： | 0 |
