To evaluate crude oil transporting efficiency through fault at the fold-thrust belt in sou-thern margin of Junggar Basin,an evaluating method on crude oil transporting efficiency through fault is established by defining fault transporting coefficient and analyzing effectiveness of crude oil accumulating process.

A set of formulae for calculating the equivalent permittivity ε_(eff) and equivalent permeability μ_(eff) of multilayer absorbing material based on reflection coefficient and transmission coefficient was presented.

The existing reflection and transmission coefficients of a frequency selective surface(FSS) do not apply to calculation of reflection and transmission under normal incidence of waves,and need to be modified.

This paper discusses the basic theory and analytical steps of using indirect ray method to calculate power transmission coefficient, boresight error and boresight error slope of large dimension radome.

The relations of transmitted and scattered radiation transfer coefficient and sensitivity with energy of radiation source,the position of scattered detector, the diameter of transmitted collimator,material of window and gas volume fraction are simulated using the software of Geant4.

After discussing the inflience caused by different negative feedback configuration s port conditions on circuit transfer coefficientG s, an united calculation formulae of source gain A· fs and clsed gain A· f, of input resistance r if and output resistance r of are found.

Derivation of the transport coefficients in composite gas;

This paper discusses the inadequacies in traditional method of inquiring transport coefficients and gives the modifiakle suggestions.
