| 1 | Evaluation model for service life of dam based on time-varying risk probability显示文摘For many dam projects in China, the 50-year designed life time is coming to an end. It is urgent to study the theory and method to evaluate the dam service life. In this paper, firstly, the probability theory of fuzzy event and time-varying effect theory are used to analyze the time-variety of various risk factors in the process of dam operations. A method is proposed to quantify the above time-variety and a model to describe the fuzzy time-varying risk probability for the dam structure is also built. Secondly, the information entropy theory is used to analyze the uncertain degree relationship between the characteristic value of membership function and fuzzy risk probability, and a mathematical method is presented to calculate the time-varying risk probability accordingly. Thirdly, the relation mode between time-varying risk probability and service life is discussed. Based on this relation mode and the acceptable risk probability of dams in China, a method is put forward to evaluate and forecast the dam service life. Finally, the proposed theory and method are used to analyze one concrete dam. The dynamic variability and mutation feature of the dam risk probability are analyzed. The remaining service life of this dam is forecasted. The obtained results can provide technology support for the project management department to make treatment measures of engineering and reasonably arrange reinforce cost. The principles in this paper have wide applicability and can be used in risk analysis for slope instability and other fields. | SU HuaiZhi WEN ZhiPing HU Jiang WU ZhongRu | 2009 | Science China(Technological Sciences)2009，52，7： | 23 |

| 3 | Evolution mechanisms of the intraseasonal oscillation associated with the Yangtze River Basin flood in 1998显示文摘With 1998 NCEP reanalysis data and the linear diagnostic equation for local me- ridional circulation, four main processes and the boundary effects with relatively large contribu- tions to the intraseasonal oscillation of the vertical branches of the East Asian meridional circula- tion are quantitatively identified among all the processes involved in the quasi-primitive equations used in the derivation of the linear diagnostic equation. The numerical results show that the main processes with maximal contributions in the lower latitudes include the latent heating and vertical transports of sensible heat. These processes are mainly associated with the tropical convective activities and result in the low-frequency cyclones in the lower latitudes. The main processes with maximal contributions in the higher latitudes are the horizontal transports of westerly momentum and horizontal temperature advections. These processes are mainly associated with the fluctua- tions in the westerlies and result in the low-frequency cyclones in the higher latitudes. The low-frequency cyclones propagating away from lower latitudes not only interact with those from higher latitudes to enhance the lifting of the moist air in the Yangtze River Basin (YRB), but also leave room for the development of the low-frequency anticyclones over the South China Sea (SCS). The southwesterly in the northwestern quadrant of the SCS anticyclones provides the YRB with abundant moisture. This favorable moisture condition along with the enhanced rising motion in the YRB leads to the extraordinary flood in 1998. | CHEN Guixing LI Weibiao YUAN Zhuojian WEN Zhiping | 2005 | Science China Earth Sciences2005，48，7： | 13 |
| 4 | Recent Progress in Studies of the Variabilities and Mechanisms of the East Asian Monsoon in a Changing Climate显示文摘Located in a monsoon domain,East Asia suffers devastating natural hazards induced by anomalous monsoon behaviors.East Asian monsoon(EAM)research has traditionally been a high priority for the Chinese climate community and is particularly challenging in a changing climate where the global mean temperature has been rising.Recent advances in studies of the variabilities and mechanisms of the EAM are reviewed in this paper,focusing on the interannual to interdecadal time scales.Some new results have been achieved in understanding the behaviors of the EAM,such as the evolution of the East Asian summer monsoon(EASM),including both its onset and withdrawal over the South China Sea,the changes in the northern boundary activity of the EASM,or the transitional climate zone in East Asia,and the cycle of the EASM and the East Asian winter monsoon and their linkages.In addition,understanding of the mechanism of the EAM variability has improved in several aspects,including the impacts of different types of ENSO on the EAM,the impacts from the Indian Ocean and Atlantic Ocean,and the roles of mid-to high-latitude processes.Finally,some scientific issues regarding our understanding of the EAM are proposed for future investigation. | Wen CHEN Lin WANG Juan FENG Zhiping WEN Tiaojiao MA Xiuqun YANG Chenghai WANG | 2019 | Advances in Atmospheric Sciences2019，36，9： | 13 |
| 5 | A primary study of the correlation between the net air-sea heat flux and the interannual variation of western North Pacific tropical cyclone track and intensity显示文摘A singular value decomposition (SVD) analysis is carried out to reveal the relationship between the interannual variation of track and intensity of the western North Pacific tropical cyclones (WNPTCs) in the tropical cyclone (TC) active season (July-November) and the global net air-sea heat flux (Q net ) in the preceding season (April-June). For this purpose, a tropical cyclone track and intensity function (TIF) is defined by a combination of accumulated cyclone energy (ACE) index and a cyclone track density function. The SVD analysis reveals that the first mode is responsible for the positive correlation between the upward heat flux in the tropical central Pacific and the increased activity of western North Pacific (WNP) TIF, the second mode for the positive correlation between the upward heat flux in the North Indian Ocean and the northeastward track shift of WNPTCs and the third mode for the negative correlation between the upward heat flux in mid-latitude central Pacific and the northwest displacement of the WNP TC-active center. This suggests that Q net anomalies in some key regions have a substantial remote impact on the WNP TC activity. | WU Liang WEN Zhiping HUANG Ronghui | 2011 | Acta Oceanologica Sinica2011，30，6： | 9 |
| 6 | Bronchial artery embolization for hemoptysis:A systematic review and meta-analysis显示文摘Objective:To assess the safety and efficacy of bronchial artery embolization(BAE)for hemoptysis.Methods and materials:Databases with articles published in English,including Pubmed,Embase,Web of science and Chochrane library,were comprehensively searched to get accurate,up-to-date and sufficient literature about BAE for hemoptysis until March 2020.The technical success rates,immediate control rates,recurrence rates,mortality rates,and total complication rates(minor and major complication rates)extracted from the articles were pooled to estimate and assess the efficacy and safety of BAE using random-effect and fixed-effect models.Results:21 articles published between 2008 and 2019,which include a total of 2511 patients,were studied to evaluate the safety and efficacy of BAE.The technical success and immediate control rates are 99.9%(95%CI:99%-100%)and 99.5%(95%CI:97.8%-99.2%),respectively.This study showed hemoptysis recurrence in 23.7%(95%CI:18.5%-28.9%)with a mortality rate of 2%(95%CI:0-3%).Additionally,the assessment of complications revealed a total complication rate of 13.4%(95%CI:7.6-19.2%),in which 0.2%(95%CI:0.2-0.4%)were major complications and 10%(95%CI:4.7-9.6%)were minor complications.Conclusion:BAE is an effective,safe,and feasible procedure with a low complication rate for hemoptysis patients.However,recurrence of hemoptysis is still at high risk after BAE due to different underlying diseases. | Zhiyuan Zheng Zhiquan Zhuang Minjie Yang Jianjun Luo Wen Zhang Zhiping Yan Xiaolin Wang | 2021 | Journal of Interventional Medicine2021，4，4： | 7 |
| 7 | Causes of the Extreme Hot Midsummer in Central and South China during 2017:Role of the Western Tropical Pacific Warming显示文摘This study investigates why an extreme hot midsummer occurred in Central and South China(CSC) during 2017. It is shown that the western North Pacific subtropical high(WNPSH) was abnormally intensified and westward-extending,resulting in anomalous high pressure and consequent extreme heat over CSC. The abnormal WNPSH was favored by the warming of the western tropical Pacific(WTP), which was unrelated to ENSO and manifested its own individual effect.The WTP warming enhanced the convection in-situ and led to anomalous high pressure over CSC via a local meridional circulation. The influence of the WTP was confirmed by CAM4 model experiments. A comparison between the 2017 midsummer and 2010 midsummer(with a stronger WNPSH but weaker extreme heat) indicated that the influence of the WNPSH on extreme heat can be modulated by the associated precipitation in the northwestern flank.The role of the WTP was verified by regression analyses on the interannual variation of the WTP sea surface temperature anomaly(SSTA). On the other hand, the WTP has undergone prominent warming during the past few decades, resulting from decadal to long-term changes and favoring extreme warm conditions. Through a mechanism similar to the interannual variation, the decadal to long-term changes have reinforced the influence of WTP warming on the temperature over CSC,contributing to the more frequent hot midsummers recently. It is estimated that more than 50% of the temperature anomaly over CSC in the 2017 midsummer was due to the WTP warming, and 40% was related to the decadal to long-term changes of the WTP SSTA. | Ruidan CHEN Zhiping WEN Riyu LU Chunzai WANG | 2019 | Advances in Atmospheric Sciences2019，36，5： | 7 |

| 9 | Leachate treatment using a demonstration aged refuse biofilter显示文摘Approximately 7000 m3 of aged refuse(AR) with a placement of over eight years was excavated from Shanghai Refuse Landfill,the largest landfill in China,and used for the construction of a two-stage bioreactor(AR biofilter) media for the biological treatment of 100 m3 of refuse landfill leachate.It was found that over 64% of COD,96.9%-99.8% of NH4+-N,and 95.8%-99.8% of BOD5 could be removed by the AR biofilter,when the leachate with initial COD,BOD5,and NH4+-N concentrations were 986-4128 mg/L,264-959 mg/L,and 538-1583 mg/L,respectively.The corresponding concentrations in the effluent were reduced to below 300-400 mg/L,2-12 mg/L,and 10-20 mg/L,respectively.The effluent was clear and pale yellow with suspended solid below 150 mg/L and color below 150 Pt/Co degree.Meanwhile,the total nitrogen removal was only 49%-63%,indicating a relative poor denitrification capacity of AR biofilter.The effluent pH was neutral and the population of Escherichia coli was less than 10-1 CFU/mL.Hence,it was considered that the demonstration project can work well for the effective treatment of leachate. | Hongjiang Li Yingying Gu Youcai Zhao Zhiping Wen | 2010 | Journal of Environmental Sciences2010，22，7： | 6 |

| 11 | Development characteristics of the fault system and its control on basin structure, Bodong Sag, East China显示文摘The Bodong Sag,located in the Bohai Sea,offshore China,is one of the most petroliferous basins in China.Based on three dimensional seismic reflection data and time slice data,we analyze the fault system of the Bodong area in detail,establish the fault structure pattern of different types and summarize the distribution of the fault system.It is concluded that the development characteristics of the Cenozoic fault system are in accordance with the dextral stress field of the Tanlu Fault,which displayed a brush structure with NNE strike-slip faults as its principal faults,NE-trending extensional faults as secondary faults and EW-trending faults as minor faults.Faults can be divided into (1) strike-slip type,(2) extensional type,(3) strike-slip extensional type and (4) extensional strike-slip type.The spatial structures of different faults have obvious differences because of the fault properties and activity intensity.The fault system at different stages shows tremendous differences because of the transition of the Tanlu Fault from sinistral strike-slip to dextral strike-slip,the transition between extension and strike-slip,and the transition from mantle upwelling to thermal subsidence.According to the controlling effect of faults on basin structure,the Cenozoic basin experienced four evolutionary stages,(a) transition stage from sinistral strike-slip to dextral strike-slip,(b) strike-slip extensional faulted stage,(c) extensional strike-slip faulted stage and (d) strike-slip depression stage.The identification of temporal and spatial differences of faults could be used as a significant guideline for oil and gas exploration in the Bodong area. | Wu Zhiping Cheng Yanjun Yan Shiyong Su Wen Wang Xin Xu Changgui Zhou Xinhuai | 2013 | Petroleum Science2013，10，4： | 4 |

| 14 | Impacts of Two Types of El Ni o on the MJO during Boreal Winter显示文摘The features of the MJO during two types of El Ni no events are investigated in this paper using the daily NCEP-2reanalysis data, OLR data from NOAA, and Real-time Multivariate MJO index for the period 1979–2012. The results indicate that the MJO exhibits distinct features during eastern Pacific(EP) El Ni no events, as compared to central Pacific(CP) El Ni no events. First, the intensity of the MJO is weakened during EP El Ni no winters from the tropical eastern Indian Ocean to the western Pacific, but enhanced during CP El Ni no winters. Second, the range of the MJO eastward propagation is different during the two types of El Ni no events. During EP El Ni no winters, the MJO propagates eastwards to 120?W, but only to 180?during CP El Ni no winters. Finally, the frequency in eight phases of the MJO may be affected by the two types of El Ni no. Phases 2 and 3 display a stronger MJO frequency during EP El Ni no winters, but phases 4 and 5 during CP El Ni no winters. | Bo PANG Zesheng CHEN Zhiping WEN Riyu LU | 2016 | Advances in Atmospheric Sciences2016，33，8： | 3 |
