1黑龙江嘉荫地区白垩纪—第三纪界线初步观察显示文摘本文报道了黑龙江嘉荫白山头地区一条新的地层剖面及其K/T界线的初步研究。新命名的“白山头段”代表乌云组下部的早古新世地层 ,含以Tiliaephyllumtsagajanicum等为代表的达宁早期植物化石。在白山头剖面上 ,作者发现可能为白垩纪末期的凝灰岩。结合与俄罗斯布列亚盆地含K/T界线的查加扬群标准剖面的对比 。孙革 孙春林 董枝明 孙跃武 吕建生 熊宪政 周忠立 余福林 邢玉玲 全成 M.A.Akhmetiev A.R.Ashraf E.Bugdaeva D.L.Dilcher L.Golovneva K.Johnson T.Kezina T.Kodrul H.Okada 2003世界地质2003,22,1:16
2In Search of the Cretaceous-Tertiary Boundary in Heilongjiang River Area of China显示文摘Abstract A new geological section recognized in Baishantou of Jiayin, Heilongjiang Province, China, was studied preliminarily in searching for the K/T boundary. An early Paleocene florule characrerized by abundant Tiliaephyllum tsagajanicum leaves and its associated plants, was collected from the Baishantou Member (new member representing the lower part of the Paleocene Wuyun Formation) overlying the possible K/T boundary. A tuff bed was found from the upper part of the Furao Formation (uppermost Cretaceous) in this section. The new findings imply that the K/T boundary is probable lying in the interval between the base of the Baishantou Member and the tuff bed, based on the correlation of the present strata with the stratotype of the Tsagajan Group spanning the K/T boundary in 'Belaya Gara' of the Bureya Basin, Russia. The early Paleocene florule from the Baishantou Member and the early-middle Maastrichtian dinosaurs found from the Yuliangzi Formation underlying the Furao Formation suggest that the Baishantou section is more promising for searching for the K/T boundary in this area. Further studies of the section is needed, integrating paleontological, biostratigraphic, geochemical, paleomagnetic, and sedimentary research would benefit our understanding the mass extinction event and biotic recovery in the Heilongjiang River area, China, and even all of northeast Asia during the K/T boundary interval.Sun G.

5Plasma Confinement Characteristics in Heliotron J——Spontaneous Change of Plasma Confinement State显示文摘Spontaneous transition of the plasma confinement mode was observed in the helicalaxis heliotron device 'Heliotron J' for three different plasma heating schemes, i.e. ECHonly, NBI-only and the combination of ECH and NBI. The transition seems to occur above a certain critical density. In addition to the confinement transition, a spontaneous shift of the hitting position of the divertor plasma flux on the wall was observed. This shift could be related with the change of the edge field topology caused by non-inductive toroidal currents.T.Mizuuchi H.Okada K.Nagasaki S.Kobayashi S.Yamamoto F.Sano K.Kondo K.Hanatani M.Nakasuga Y.Nakamura Y.Suzuki Y.Manabe H.Shidara H.Kawazome M.Kaneko Y.Nishioka Y.Ohno T.Takamiya H.Yukimoto Y.Fukagawa Y.Morita S.Nakazawa S.Nishio K.Takahashi S.Tuboi M.Yamada K.Ohashi Y.Ijiri T.Senju K.Yaguchi K.Sakamoto K.Tohshi M.Shibano T.Obiki 2004Plasma Science and Technology2004,6,4:1

7Observation of Edge Plasma Fluctuations with a Fast Camera in Heliotron J显示文摘A fast video camera is verified to be a powerful tool for observation of filaments/blobs near the last closed flux surface (LCFS).In order to extract the fluctuation component from the raw data of the fast camera,a pre-processing technique,sliding time window averaging subtraction (STWAS) has been developed to remove the background of slowly varying emission from the bulk plasma.By using this pre-processing technique,the fast camera data are analyzed.A method to identify the filaments in the pre-processed image is also discussed.臧临阁 M.TAKEUCHI N.NISHINO T.MIZUUCHI S.OHSHIMA K.KASAJIMA M.SHA K.MUKAI H.Y.LEE K.NAGASAKI H.OKADA T.MINAMI S.KOBAYASHI S.YAMAMOTO K.HANATANI Y.NAKAMURA S.KONOSHIMA F.SANO 2013Plasma Science and Technology2013,15,3:0
8西南日本晚中生代和早新生代沉积盆地的性质和发育显示文摘1 前言 日本列岛晚中生代到早第三纪沉积盆地具有区域性构造和沉积特征。本研究中,重建了晚中生代至早新生代期间亚洲东缘的古地理,得到的认识是,日本海只是在早第三纪最晚期至早中新世期间才开始存在。 在西南日本,上中生界至下新生界沉积岩包含了活动大陆边缘的主要地质单元,并显示出沉积盆地的特征分布。可明显地区分出弧后、弧内和弧前沉积盆地。西南日本的弧后盆地提供了与亚洲大陆东部边缘的盆地构造连续性的证据。H.Okada 韩林 1994海洋石油1994,0,6:0
9耕作和施肥对日本大豆田线虫种群结构的影响显示文摘免耕体系(NT)下土壤生物区系多样,真菌的降解速度慢。然而有时候通过分析线虫种群结构不能发现免耕土壤的这一特征,主要是由于以往研究的试验处理或是取样时期太短或是没有代表性。土壤线虫的分布因地理位置和土壤类型而异,这对利用线虫种群结构分析评价土壤生物多样性产生一定的影响。H.Okada H.Harada 潘凤娟(摘译) 2011大豆科技2011,,1:0
