The results show that the flow distribution in plate-fin heat exchangers can be effectively improved by changing the header configuration. It is also found that the effect of header configuration on the flow maldistribution in crosswise direction at the outlet area is greater than that in lengthwise direction.

In this paper we will mainly study the gauge fixing Yang-Mills heat flow of a principal bundleFor a principle bundle with a compact seme-simple Lie group as its structure group over a compact Riemannian manifold without boundary, the evolutions of the curvature and its higher derivatives under the flow above will be derived, and the energy inequality and the Bochner type estimates will be obtained. Then, the monotonicity formula and the small action regularity theorem can be proved. We will give the locally uniform estimates for the higher derivatives of the curvature.

The first systematic and fundamental research is did by Modigliani and Miler, they bring out with the famous MM theorem in 1958.Which says capital structure doesn't affect enterprise market value and average capital cost in a condition of perfect market. After that, several economists including Modigliani and Miler themselves put this theory forward with the MM theorem with the consideration of tax, the trade-off theory, the pecking order theory,market for corporate control, these analyses throw lights on the problem from different aspect.
对此做出系统性和开创性研究的是Modigliani和Miler,在1958年提出了资本成本与资本结构无关的MM定理,在此基础上,包括Modigliani和Miller在内的许多经济学家对此进行了探索,他们先后提出了考虑税收的MM定理、权衡理论、优序融资理论、控制权理论,从不同的角度分析了资本结构的优化问题。
