Heat Transfe for Power Law Non-Newtonian Fluids

We present a theoretical analysis for heat transfer in power law non-Newtonian fluid by assuming that the thermal diffusivity is a function of temperature gradient. The laminar boundary layer energy equation is considered as an example to illustrate the application. It is shown that the boundary layer energy equation subject to the corresponding boundary conditions can be transformed to a boundary value problem of a nonlinear ordinary differential equation when similarity variables are introduced. Numerical solutions of the similarity energy equation are presented.

关于一个生物化学系统稳态解的整体分歧

1.引言 1974年,M.C.Duban、J.P.Kernevez和D.Thomas建立了关于单酶人造膜的一个数学模型——Thomas模型。他们用尿酸作为培养基,氧气作为辅作用物,而酶催化剂是尿素。相应的化学方程式是:尿酸+氧 尿素→尿膜+其它.设s=s(x,t)为人造膜的培养基的浓度。则它满足下列的反应扩散方程:

关于二审民事调解工作的体会

全国公安、检察、司法先进工作者大会已于5月11日在北京召开。这提政法界一件鼓舞人心的大事。我们向出席大会的先进单位和先进工作者表示敬意。我们除把罗瑞卿副总理在大会上的讲话登载于刊首之外,为了使广大的读者便于学习他们的先进经验,在这里摘要发表几篇先进单位,先进工作者的发言和先进事迹。
