1基于连续型定子磁链轨迹的异步牵引电机低转矩脉动控制算法显示文摘本文提出了一种定子磁链轨迹优化的异步牵引电机基速以内的中高速区直接转矩控制(Direct Torque Control,DTC)算法。所提出DTC算法是从以改善转矩脉动角度出发,牵引电机在基速以内的中高速度运行阶段时,随着转速的增加,通过实现定子磁链轨迹从圆形-多边形-六边形的连续切换,获得转矩脉动小与平稳,磁链轨迹平滑、开关频率利用率以及谐波消除能力等的提高。该DTC算法仅需在传统DTC基础结构上仅增加定子磁链调节算法即可,因此它的主要优点是算法简单性,并保留了传统DTC算法快速动态响应,控制电路不复杂,对电机参数依赖性低等特征。理论分析和实验结果都证明了该连续型磁链轨迹的DTC算法的有效性和可行性。范文进-Pham Van Tien 郑琼林 杨中平 林飞 宋文胜 Do Viet Dung 2015电工技术学报2015,30,12:3

4Ecoregional variations of aboveground biomass and stand structure in evergreen broadleaved forests显示文摘Biotic and abiotic factors control aboveground biomass(AGB)and the structure of forest ecosystems.This study analyses the variation of AGB and stand structure of evergreen broadleaved forests among six ecoregions of Vietnam.A data set of 1731-ha plots from 52 locations in undisturbed old-growth forests was developed.The results indicate that basal area and AGB are closely correlated with annual precipitation,but not with annual temperature,evaporation or hours of sunshine.Basal area and AGB are positively correlated with trees>30 cm DBH.Most areas surveyed(52.6%)in these old-growth forests had AGB of 100–200 Mg ha^-1;5.2%had AGB of 400–500 Mg ha^-1,and 0.6%had AGB of>800 Mg ha^-1.Seventy percent of the areas surveyed had stand densities of 300–600 ind.ha^-1,and 64%had basal areas of 20–40 m^2 ha^-1.Precipitation is an important factor influencing the AGB of old-growth,evergreen broadleaved forests in Vietnam.Disturbances causing the loss of large-diameter trees(e.g.,>100 cm DBH)affects AGB but may not seriously affect stand density.Tran Van Do Mamoru Yamamoto Osamu Kozan Vo Dai Hai Phung Dinh Trung Nguyen Toan Thang Lai Thanh Hai Vu Thanh Nam Trieu Thai Hung Hoang Van Thang Tran Duc Manh Cao Chi Khiem Vu Tien Lam Nguyen Quang Hung Tran Hoang Quy Pham Quang Tuyen Trinh Ngoc Bon Nguyen Thi Thu Phuong Ninh Viet Khuong Nguyen Van Tuan Dang Thi Hai Ha Tran Hai Long Dang Van Thuyet Dang Thinh Trieu Nguyen Van Thinh Tran Anh Hai Duong Quang Trung Nguyen Van Bich Dinh Hai Dang Pham Tien Dung Nguyen Huy Hoang Le Thi Hanh Phan Minh Quang Nguyen Thi Thuy Huong Hoang Thanh Son Nguyen Thanh Son Nguyen Thi Van Anh Nguyen Thi Hoai Anh Pham Dinh Sam Hoang Thi Nhung Hoang Van Thanh Nguyen Huu Thinh Tran Hong Van Ho Trung Luong Bui Kieu Hung 2020Journal of Forestry Research2020,31,5:1

6Fluctuating temperature modifies heat-mortality association around the globe显示文摘Studies have investigated the effects of heat and temperature variability(TV)on mortality.However,few assessed whether TV modifies the heat-mortality association.Data on daily temperature and mortality in the warm season were collected from 717 locations across 36 countries.TV was calculated as the standard deviation of the average of the same and previous days’minimum and maximum temperatures.Yao Wu Bo Wen Shanshan Li Antonio Gasparrini Shilu Tong Ala Overcenco Ales Urban Alexandra Schneider Alireza Entezari Ana Maria Vicedo-Cabrera Antonella Zanobetti Antonis Analitis Ariana Zeka Aurelio Tobias Barrak Alahmad Ben Armstrong Bertil Forsberg CarmenÍñiguez Caroline Ameling César De la Cruz Valencia ChristoferÅström Danny Houthuijs Do Van Dung Dominic Royé Ene Indermitte Eric Lavigne Fatemeh Mayvaneh Fiorella Acquaotta Francesca de’Donato Francesco Sera Gabriel Carrasco-Escobar Haidong Kan Hans Orru Ho Kim Iulian-Horia Holobaca Jan Kyselý Joana Madureira Joel Schwartz Klea Katsouyanni Magali Hurtado-Diaz Martina SRagettli Masahiro Hashizume Mathilde Pascal Micheline de Sousa Zanotti Stagliorio Coélho Noah Scovronick Paola Michelozzi Patrick Goodman Paulo Hilario Nascimento Saldiva Rosana Abrutzky Samuel Osorio Tran Ngoc Dang Valentina Colistro Veronika Huber Whanhee Lee Xerxes Seposo Yasushi Honda Michelle L.Bell Yuming Guo 2022The Innovation2022,3,2:0
7Hydrogen roles approaching ideal electrical and optical properties for undoped and Al doped ZnO thin films显示文摘This paper distinguished hydrogen roles to improve electron mobility and carrier concentration in ZnO and Al doped ZnO sputtered films.By combining experimental evidences and theoretical results,we find out that hydrogen located at oxygen vacancy sites(H_(O))is the main factor gives rise to increase simultaneously mobility and carrier concentration which has not been mentioned before.Introducing appropriate hydrogen content during sputtering not only results in crystalline relaxation but also supports doping Al into ZnO,increasing carrier concentration and electron mobility in the film.First principles calculations confirmed hydrogen substitutional stability for oxygen vacancy,significantly reducing electron conductivity effective mass and hence increasing electron mobility.In particular,0.8%hydrogen partial pressure ratio achieved 61 cm^(2)V^(-1)s^(-1)maximum electron mobility,optical transmittance above 82%in visible and near-infrared regions,and 2×10^(20) cm^(-3)carrier concentrations for H-Al co-doped ZnO film.These values approach ideal electrical and optical properties for transparent conducting oxide films.The presence of one maximum electron mobility was attributed to competition between increasing mobility due to restoring effective electron mass and hydrogen passivation of native defects,and decreased electron mobility due to electron-phonon scattering.Dung Van Hoang Nam Hoang Vu Nga Thi Do Anh Tuan Thanh Pham Truong Huu Nguyen Jer-Lai Kuo Thang Bach Phan Vinh Cao Tran 2022Journal of Materiomics2022,8,1:0
8唤醒空间!城市生态阳台,河内,越南显示文摘我们是来自越南及意大利的青年建筑师团队,在越南开设了一家建筑工作室。2016年10月,我们在河内租赁了一个办公空间。在了解河内市周边环境后,我们发现,可能由于市区里的灰尘、噪音和防盗等问题,这里有很多阳台都未被实际使用。市民几乎不与外部环境或附近的邻居互动。我们把那些阳台称为沉寂空间。 An Viet Dung Roberto Iannetti Pham Ngoc Linh An Thanh Nhan Nelly Agliardi Quach Hai Linh Bui Huu Tung Le Van Tung Do Thi Hien Nguyen Phi Hung Due Chu Bang Thanh 天妮(译) Nguyen Thai Thach(摄影) Quang Tran(摄影) 2020世界建筑2020,,10:0
