| 1 | Turbulent lock release gravity current显示文摘The time evolution of a turbulent lock release gravity current, formed by a finite volume ofhomogeneous fluid released instantaneously into another fluid of slightly lower density, was studied byexperimental measurements of the density structure via elaborate digital image processing and by a nu-merical simulation of the flow and mixing using a two-equation turbulence model. The essential fact thatthe gravity current passes through an initial slumping phase in which the current head advances steadilyand a second self-similar phase in which the front velocity decreases like the negative third power of thetime after release is satisfactorily presented by the laboratory observation. An overall entrainment ratioproportional to the distance from the release point is found by the numerical simulation. The renormal-ization group (RNG) k- ε model for Reynolds-stress closure is validated to characterize the gravitycurrent with transitional and localized turbulence. | 陈国谦 Joseph H.w.Lee | 2001 | Science China(Technological Sciences)2001，44，5： | 1 |
| 2 | 三维周期花纹轮胎滚动阻力和温度分布的数值估算显示文摘汽车轮胎在路面滚动行驶时,其橡胶组件的应变和应力以动态变形方式经历周期变化,由于受到应力与应变时间历程固有相位差影响而产生严重滞后损失。滚动轮胎的滞后损失成为造成轮胎能量耗散的关键因素,且每一周滞后损失可视为阻碍轮胎滚动的虚拟力。该虚拟力通常被称为滚动阻力,为了发展节能汽车,降低轮胎滚动阻力是当今全球范围内的巨大挑战。 | J.R.Cho H.W.Lee W.B.Jeong K.M.Jeong K.W.Kim 肖大玲(摘译) 吴淑华(校) 徐立(校) | 2014 | 轮胎工业2014，34，1： | 1 |

| 4 | ZAKHAROV EQUATION FOR SURFACE GRAVITY WAVES IN SHEAR FLOW显示文摘The fourth-order Zakharov integral equation for surface gravity waves derived by Stiasshie and Shemer is modified to include the effect of shear flow. Using this new equation the class instability of a Stokes wave train in shear flow is studied. The effect of the vorticity on the instability is discussed, and a kind of new unstable regions has been found. | 周清甫 Y.K.CHEUNG JOSEPH H.W.LEE | 1990 | Science China Mathematics1990，33，10： | 0 |
| 5 | 电视应用的LCD技术显示文摘宽视角和快速灰到灰响应时间是电视应具备的几点最重要的特性。在标准的LCD模式中,超级IPS技术在电视应用的几个方面都具有内在的优越性[1]。即使这样,包括亮度、对比度、彩色色域等所有常见的规格都需要优化。我们必须在人体感知的基础上,以合理的方法分析所有的规格。然而全面来看,仍然有运动图像、响应时间和功耗等领域需要改进。 | S.D.Yeo C.H.Oh H.W.Lee M.H.Park 陈小平 | 2006 | 现代显示2006，，1： | 0 |
