Preparing method of low-reflectivity spherical copper powder for 3D printing

The invention belongs to the technical field of 3D printing, and particularly relates to a preparing method of low-reflectivity spherical copper powder for 3D printing. The preparing method includes the following steps that copper or copper alloy is used as a raw material, and atomized copper powder is prepared through a gas atomization method; the atomized copper powder is screened; low-temperature oxidizing roasting is carried out on the copper powder which is obtained after screening and is of different specifications, so that surface oxidation of the copper powder is achieved; the copper powder obtained after oxidation is put in the hydrogen protective atmosphere to be roasted in a reduced mode, and the copper powder after surface oxidation is reduced again. Compared with the prior art, the atomized copper powder is prepared through the gas atomization method, then the atomized copper powder is reduced, finally the oxygen content of the copper powder is reduced to meet the requirement of 3D printing, and the copper powder microcosmically represents high surface roughness in the oxidation state. By means of the process design, the laser reflectivity is effectively reduced, and the energy rate of laser absorbed by the copper powder is increased.

Energy efficiency optimization method in MIMO distributed base station system

The invention discloses an energy efficiency optimization method in a single-user MIMO distributed base station system. The energy efficiency optimization method comprises the following steps: firstly, constructing an energy efficiency optimization problem model under a given remote access point set, and transforming the problem model into three sub-problems, namely a rate maximization problem, an energy efficiency optimization problem without rate constraint and a power minimization problem under the rate constraint, for solution, thereby obtaining the optimal solution of a transmission covariance and the maximal energy efficiency; and then orderly bringing access points into an activated access point set in an order from small to large distances between a user and the access points, obtaining the maximal energy efficiency based on the energy rate optimization problem model and determining an access point set finally selected to transmit information to the user. The energy efficiency optimization method in the single-user MIMO distributed base station system is capable of solving the problem of base station transmission pre-coding design in the single-user MIMO distributed base station system and the problem of how to select appropriate distributed access points to maximize the energy efficiency of the system; besides, the energy efficiency optimization method is capable of quickly converging the optimal solution.
