爱的信笺

新东方英语（中英文版） 2010年第12期 52-54页

作者： david osborne 蒋明思

你问过我，当我出航时，你可以寄什么给我——在千里之外的航船上，那些我想要却无法得到的东西。我想这份清单不难列出，只恐不易兑现。

把爱寄绐我

作者： david E.osborne 朱俊

这是一位即将退役的海军写给新婚妻子的书信。读罢,不禁想起了林觉民的《与妻书》,“窗外疏梅筛月影,依稀掩映,吾与汝并肩携手,低低切切,何事不语,何情不诉!……”两封“与妻书”,一中一外,一古一今,同中有异。新婚燕尔,分隔两地,借信... 详细信息

这是一位即将退役的海军写给新婚妻子的书信。读罢,不禁想起了林觉民的《与妻书》,“窗外疏梅筛月影,依稀掩映,吾与汝并肩携手,低低切切,何事不语,何情不诉!……”两封“与妻书”,一中一外,一古一今,同中有异。新婚燕尔,分隔两地,借信笺传情,字里行间无不流露出浓情蜜意,这是两者的共同点。但由于所处时代以及环境等种种不同,两者又各有特色:海军的“与妻书”通过一系列的排比句细说深情和思念,将爱情的甜蜜和生活的幸福烘托得恰到好处;而林觉民的《与妻书》,确切说是“与妻诀别书”,却是一字一血泪,一语一悲恸!有心的读者不妨把两者对比来读,相信会有所感悟。

The synthesis of a promising brain imaging agent 4-[F-18]fluoro-4-deoxy-N-acetyl-1,3,6-tri-O-acetylglucosamine, 2, was successfully accomplished from commercially available N-acetyl glucosamine in 5 steps. The non-decay corrected radiochemical yield and purity were found to be 31% ± 4% (n = 3) and >98% respectively. The total reaction time for radio labelling step was 50 min.

Acta Mathematica Scientia 2009年第4期29卷 919-948页

作者： Dan osborne Mathematical Institute University of Oxford 24-29 St Giles

We study the initial-boundary value problem of the Navier-Stokes equations for incompressible fluids in a general domain in R^n with compact and smooth boundary, subject to the kinematic and vorticity boundary conditions on the non-flat boundary. We observe that, under the nonhomogeneous boundary conditions, the pressure p can be still recovered by solving the Neumann problem for the Poisson equation. Then we establish the well-posedness of the unsteady Stokes equations and employ the solution to reduce our initial-boundary value problem into an initial-boundary value problem with absolute boundary conditions. Based on this, we first establish the well-posedness for an appropriate local linearized problem with the absolute boundary conditions and the initial condition （without the incompressibility condition）, which establishes a velocity mapping. Then we develop apriori estimates for the velocity mapping, especially involving the Sobolev norm for the time-derivative of the mapping to deal with the complicated boundary conditions, which leads to the existence of the fixed point of the mapping and the existence of solutions to our initial-boundary value problem. Finally, we establish that, when the viscosity coefficient tends zero, the strong solutions of the initial-boundary value problem in R^n（n ≥ 3） with nonhomogeneous vorticity boundary condition converge in L^2 to the corresponding Euler equations satisfying the kinematic condition.
