1陶瓷部件的浆料打印快速成型(英文)显示文摘采用Sanders公司的四打印头快速成型机进行了陶瓷部件的浆料打印成型实验 ,实际测试了所用四打印头快速成型机的打印工作条件 ,考察了石蜡和挥发性介质两种浆料技术路线 ,并采用石蜡为介质制备了钛酸钡陶瓷浆料 ,研究了其流变性能 .实验表明 ,虽然偶联剂的加入可以降低石蜡介质浆料的粘度 ,但是粘度足够低的可打印浆料的固相含量太低 [约 3 % (involume)以下 ] ,打印成型后不能完全烧结 ,因此 ,要通过打印成型出可完全烧结的陶瓷部件便只能采用挥发性液体作为浆料介质 。王树海 Jang J H Schulze W A Pilgrim S M 2001硅酸盐学报2001,29,4:10

4National Forest Inventories capture the multifunctionality of managed forests in Germany显示文摘Background:Forests perform various important ecosystem functions that contribute to ecosystem services.In many parts of the world,forest management has shifted from a focus on timber production to multi-purpose forestry,combining timber production with the supply of other forest ecosystem services.However,it is unclear which forest types provide which ecosystem services and to what extent forests primarily managed for timber already supply multiple ecosystem services.Based on a comprehensive dataset collected across 150 forest plots in three regions differing in management intensity and species composition,we develop models to predict the potential supply of 13 ecosystem services.We use those models to assess the level of multifunctionality of managed forests at the national level using national forest inventory data.Results:Looking at the potential supply of ecosystem services,we found trade-offs(e.g.between both bark beetle control or dung decomposition and both productivity or soil carbon stocks)as well as synergies(e.g.for temperature regulation,carbon storage and culturally interesting plants)across the 53 most dominant forest types in Germany.No single forest type provided all ecosystem services equally.Some ecosystem services showed comparable levels across forest types(e.g.decomposition or richness of saprotrophs),while others varied strongly,depending on forest structural attributes(e.g.phosphorous availability or cover of edible plants)or tree species composition(e.g.potential nitrification activity).Variability in potential supply of ecosystem services was only to a lesser extent driven by environmental conditions.However,the geographic variation in ecosystem function supply across Germany was closely linked with the distribution of main tree species.Conclusions:Our results show that forest multifunctionality is limited to subsets of ecosystem services.The importance of tree species composition highlights that a lack of multifunctionality at the stand level can be compensated by managing forests at the landscape level,when stands of complementary forest types are combined.These results imply that multi-purpose forestry should be based on a variety of forest types requiring coordinated planning across larger spatial scales.Nadja K.Simons María R.Felipe-Lucia Peter Schall Christian Ammer Jürgen Bauhus Nico Blüthgen Steffen Boch François Buscot Markus Fischer Kezia Goldmann Martin M.Gossner Falk Hänsel Kirsten Jung Peter Manning Thomas Nauss Yvonne Oelmann Rodica Pena Andrea Polle Swen C.Renner Michael Schloter Ingo Schöning Ernst-Detlef Schulze Emily F.Solly Elisabeth Sorkau Barbara Stempfhuber Tesfaye Wubet Jörg Müller Sebastian Seibold Wolfgang W.Weisser 2021Forest Ecosystems2021,8,1:2
5直接光控晶闸管在脉冲电源上的应用显示文摘具有集成保护功能的直接光控晶闸管 (LTT)已得到了广泛应用。这种晶闸管是为高压直流输电(HVDC)而开发的。通过改进门极结构 ,光控晶闸管也可用于大功率脉冲电源上。由于采用了直接光触发 ,LTT特别适用于串联应用。J Przybilla R Keller U Kellner C Schneider H J Schulze F J Niedernostheide 2002电力电子技术2002,36,6:2
