SJ series high frequency deflaker is absorbed the optimum deflaker device in the world by our factory。The device can obviously decrease pulp point and defibraze the fiber with high wet strength.
Taking the supplying regions as rows of the bigraph, the optimum scheme for looped grids feeder arrangement with minimum cost is obtained by a minimum weight match algorithm of bigraph.
In the actual system, the grinding wheel of metal binding agent is electrolytically dressed with the determined optimum elec trolytic grinding fluid and the satisfied dressing result is obtained.
On condition that the front body shape of the projectile is unchangeable,a formula is obtained for determining the relation between the optimum boattail angle and the supersonic flight region.
That we use finite element analysis calculate to the strength and the rigidity of the bodywork structure.Thus the optimum fillet of the small underframe structure can be specified.
Moreover, it is find that the optimum length between deuterohemin and His is one residue, and all of the monomers are more active than their corresponding dimmers.
Counterfort retaining walls are optimized in the paper, using the optimum program, costs of different counterfort retaining wall parameters were calculated and based on the contrast analysis.
The increase of cellulous fiber in the hybrid fiber can result in the increase of optimum asphalt content, the reduction of density, air voids and Marshall stability.
