In this paper,according to Reichardt s cubic law of incom-pressible turbulent boundary layer,an explicit expression of the velocity distribution in the turbulent boundary layer is obtained,which is more agreeable to Spalding’s formula and experimental data than the present expressions of Musker,A.

A set of high-temperature and flowing calorimetric apparatus for determination of heat sinks of endothermic hydrocarbon fuels was set up which is based on one dimensional thermal conduction model of Fourier's law and Tian's equation.

First,by utilizing classical Gauss motion equations,we derived the three separate control laws,which could maximize the time rate of change of a desired orbital element.
