As to the reasonable matching between the resources needed by multi-task and M-dimensional resources offered by multiprocessing nodes,the author offered multiple dimension set partitioning optimization models,defined the function of resource balancing degree and proposed a Multiple Dimension Set Partitioning Load Balancing Resource Optimization Allocation Algorithm(MDSPLBROAA),which can optimize to solve the NP problems.
Research proved that it is feasible to seawater distillation with exhaust steam generated by 2×125MW back pressure type turbines,and produce 570,000 ton fresh water per day,with rational matching of power thermal system and Multi-Stage Flash system.
研究证明,电厂热力系统与多级闪蒸系统(Mu lti-Stage F lash)合理匹配,用2×125MW背压式汽轮机排汽进行海水淡化,日外供水量57万吨是可行的。
Rational matching of section milling parameter is key to improve section milling velocity. Circulation displacement and drilling fluid property is decisive factor of cutting scrap iron. Through research on section milling technology at home and abroad,calculating formula of theoretical displacement in section milling is given.
This research through to the ZS1100N diesel engine cooling system analysis and the improvement design, through the reasonable match of the radiator and the ventilator, enables this system to achieve the quite ideal cooling effect, and discusses the general design method of this form cooling system.
A mathematical model for the impact system of the hydraulic hammer with liquid cushion is established in accordance with the one dimension wave theory and spring effect of the liquid. Based on this model, the influences of the liquid cushion on the stress of the impact system and on the efficiency of energy transfer were experimentally investigated, thereby obtaining a reasonable match of the thickness of the liquid cushion with the parameters of the impact system.
When center fracture appears, it is solved by rational match of pass draught and wire drawing die work cone angle, which ensures draught is more than 20 percent as work cone angle is at 14°and the draught is more than 18.5 percent as the angle is at 12°.
