Teachers' rights security receives more and more attention from all walks of life under the strong education province and along with the gradual enlargement gap in the rich and the poor of various fields of cities and towns, the rights and interests of teachers in the rural primary and secondary schools do not ensure the situation far from the urban teacher. So, Pay close attention to rural middle...
Ohmic contacts to n-type GaSb have been investigated. Some drawbacks are associated with conventional Ni/AuGe/Au Ohmic contact of n-GaSb, so we propose to add a Mo diffusion barrier between AuGeNi and Au layer and carry out the structure fabrication experiment. The results show that the new metallization decreases the specific contact resistance and can be annealed at wide temperature range. It is...
A numerical simulation model based on the KIVA code was carried out for a DI diesel engine in-cylinder process. Two candidate chambers were compared with the original chamber to study their effects on combustion and emission characteristics. The results show that low emission was achieved in the chamber C with maximal bowl diameter and bowl depth. Compared with the original chamber, Soot and NOx of...
A kind of cubic algebraic trigonometric B-spline base functions with a shape control parameter is presented, and the corresponding curves are defined by the introduced base functions. The curves inherit some properties with traditional cubic B-spline curves and can interpolate directly some control points without solving system of equations or inserting some additional control points. The curves can...
A new kind of interpolation splines with a shape parameter over the algebraic trigonometric function space Ω=span {1, t, sint, cost, sint2t, cos2t} is presented, which are called cubic algebraic trigonometric splines. The cubic algebraic trigonometric splines have many similar properties to cubic B-splines. The corresponding spline curves and surfaces can interpolate directly some control points without...
