In the railway network planning, effective information for the project decision can not be provided, because it is hard to get the expanding coefficient.

A method for constructing exact solutions of nonlinear evolution equation with variable coefficients

The effects of the contents of the acrylate and vinylidene chloride on the contact angle(θ) on PET,the extend coefficient(S) on PET and the surface free energy of the emulsion(γ 1)were also studied.

So the selection of the spread factor in th e box pass and flat oval pass of continuous casting billet are studied.

Flow and heat transfer of spray cooling can be reflected by a droplet spreading coefficient, which is dependent on the droplet initial size and velocity.

The basic principle of measuring spreading coefficients by the large sessile drop method has been introduced.

The heuristic search algorithm was applied to calibrate the path stretch coefficient of expressway network and the scale of effective multipaths was identified.
