6用于IGCT的具有很高SOA能力的大面积快恢复二极管显示文摘为IGCT的应用而开发的大面积(>50cm2)4.5kV快恢复硅二极管具有很低的漏电流以及直至140℃的高安全工作区SOA。为了获得软的反向恢复特性和在2.8kV下100FIT的抗宇宙射线辐射能力,对硅器件的设计及少子寿命控制进行了优化。此外,用离子辐照在阳极缓冲层反向偏置空间电荷区RBSOA中造成的缺陷峰值与电子辐照相结合的方法,可以塑造通态等离子体的形状、减小反向恢复损耗。除了低的漏电流之外,新设计还提供了非常坚固的阳极,在反向恢复期间没有di/dt扼流线圈的情况下,阳极能够承受高达10kA/μs的di/dt。本文还给出了低能电子辐照与高能电子辐照二极管一些主要参数的比较,这些参数有漏电流、正向压降的温度系数、正向压降V_F与反向恢复损耗E_(rec)的关系曲线、反向恢复软度以及浪涌电流等。J.VobeckY R.Siegrist M.Arnold K.Tugan 张斌 2011电力电子2011,,4:0
7Direct impacts of climatic warming on heat stress in endothermic species: seabirds as bioindicators of changing thermoregulatory constraints显示文摘There is now abundant evidence that contemporary climatic change has indirectly affected a wide-range of spe­cies by changing trophic interactions,competition,epidemiology and habitat.However,direct physiological im­pacts of changing climates are rarely reported for endothermic species,despite being commonly reported for ec­totherms.We review the evidence for changing physiological constraints on endothermic vertebrates at high temperatures,integrating theoretical and empirical perspectives on the morphology,physiology and behavior of marine birds.Potential for increasing heat stress exposure depends on changes in multiple environmental vari­ables,not just air temperature,as well as organism-specific morphology,physiology and behavior.Endotherms breeding at high latitudes are vulnerable to the forecast,extensive temperature changes because of the adap­tations they possess to minimize heat loss.Low-latitude species will also be challenged as they currently live close to their thermal limits and will likely suffer future water shortages.Small,highly-active species,particu­larly aerial foragers,are acutely vulnerable as they are least able to dissipate heat at high temperatures.Overall,direct physiological impacts of climatic change appear underrepresented in the published literature,but avail­able data suggest they have much potential to shape behavior,morphology and distribution of endothermic spe­cies.Coincidence between future heat stress events and other energetic constraints on endotherms remains largely unexplored but will be key in determining the physiological impacts of climatic change.Multi-scale,biophysical modeling,informed by experiments that quantify thermoregulatory responses of endotherms to heat stress,is an essential precursor to urgently-needed analyses at the population or species level.Stephen A.OSWALD Jennifer M.ARNOLD 2012Integrative Zoology2012,7,2:0
8Twenty-first century climate change and submerged aquatic vegetation in a temperate estuary:the case of Chesapeake Bay显示文摘Introduction:The Chesapeake Bay was once renowned for expansive meadows of submerged aquatic vegetation(SAV).However,only 10%of the original meadows survive.Future restoration effortswill be complicated by accelerating climate change,including physiological stressors such as a predicted mean temperature increase of 2-6℃and a 50-160%increase in CO_(2)concentrations.Outcomes:As the Chesapeake Bay begins to exhibit characteristics of a subtropical estuary,summer heat waves will become more frequent and severe.Warming alone would eventually eliminate eelgrass(Zostera marina)from the region.It will favor native heat-tolerant species such as widgeon grass(Ruppia maritima)while facilitating colonization by non-native seagrasses(e.g.,Halodule spp.).Intensifying human activity will also fuel coastal zone acidification and the resulting high CO_(2)/low pH conditions may benefit SAV via a“CO_(2)fertilization effect.”Discussion:Acidification is known to offset the effects of thermal stress and may have similar effects in estuaries,assuming water clarity is sufficient to support CO_(2)-stimulated photosynthesis and plants are not overgrown by epiphytes.However,coastal zone acidification is variable,driven mostly by local biological processes that may or may not always counterbalance the effects of regional warming.This precarious equipoise between two forces-thermal stress and acidification-will be critically important because it may ultimately determine the fate of cool-water plants such as Zostera marina in the Chesapeake Bay.Conclusion:The combined impacts of warming,coastal zone acidification,water clarity,and overgrowth of competing algae will determine the fate of SAV communities in rapidly changing temperate estuaries.Thomas M.Arnold Richard C.Zimmerman Katharina A.M.Engelhardt J.Court Stevenson 2017Ecosystem Health and Sustainability2017,3,7:0
