| 1 | 《Routledge语言测试手册》评介显示文摘1.引言 自2010年以来,Routledge出版公司陆续推出了一系列应用语言学手册丛书,其中《语言测试手册》于2012年出版。该手册的两位编者都是国际语言测试界的权威学者。Fulcher现为英国莱斯特大学教授,担任国际语言测试界权威期刊《语言测试》(L anguage Testing)的主编;Davidson 现为美国伊利诺伊大学教授。他们曾经一起合作撰写过一本教材《语言测试与评估:高级读本》(Fulcher & Davidson 2007)。该教材由Routledge出版公司于2007年出版,属于该公司应用语言学系列教材之一。它的出版产生了巨大反响,被誉为语言测试专业师生必读教材(Brown 2011)。《语言测试手册》是《语言测试与评估:高级读本》的延续,面向语言测试的开发者、使用者、研究者以及相关政策制定者,是一本语言测试研究的必备参考书。 | 徐鹰 Fulcher G.

| 2 | Magnetic resonance studies of a gas-solids fluidised bed:Jet-jet and jet-wall interactions显示文摘Magnetic resonance imaging(MRI)gave images of air jets from orifices in the distributor plate of a bed of poppy seeds.Attention focused on two features:(1)The interaction between nearby vertical jets from two,three or four orifices;(2)Wall effects,where one or more orifices created vertical jets near the vertical wall of the cylinder containing the particle bed.The results show that nearby jets are mutually attracted.Likewise a jet near a wall bends out of the vertical,towards the wall.For multiple adjacent jets,the jet lengths show dependence on orifice layout:the lengths are in reasonable agreement with published measurements,by other methods,for single jets.The MRI gives three-dimensional images of the single jets and of multiple jets,separate or merging. | Meenal Pore Daniel J.Holland Thusara C.Chandrasekera Christoph R.Müller Andrew J.Sederman John S.Dennis Lynn F.Gladden John F.Davidson | 2010 | Particuology2010，8，6： | 2 |
| 3 | Gas flow in rotary kilns显示文摘This paper describes an experimental investigation on the flow characteristics within a rotating cylinder containing a rolling bed of sand.The axis of the cylinder was horizontal and there was no axial bulk flow of particles.The velocity field of the gas flowing through the cylinder was measured by hot-wire anemometry.The measurements indicate that the velocity field is asymmetric with respect to a diameter perpendicular to the granular bed.CFD calculations confirm this finding.The gas velocity profiles are crucial in determining heat transfer from gas to solid. | Patrick R.Davies Michael J.S.Norton D.Ian Wilson John F.Davidson David M.Scott | 2010 | Particuology2010，8，6： | 1 |
