Design and verification of CPU for teaching has been a hotspot of computer professional teaching. The simulation experiment is given priority to in the computer system structure and principle experiment course offered by the University at present and this is not conducive to students making the theory and the modern computer industry combination. To improve the quality of practice teaching for computer...
The mechanism of homogeneous charge compression ignition (HCCI) combustion is introduced. Based on single zone model of HCCI combustion under early injection, coupled with fuel oxidation reaction dynamical model, the mathematics combustion model in cylinder is built and simulated, then the engine's working characteristics combusted with the biodiesel and diesel oil is compared with the original, it...
The separation efficiency and resistance loss of curved plate affected by blade spacing, and velocity and average particle size are experimentally investigated. Meanwhile, a new measuring device is used to detect the moisture content. The results show that dehydration efficiency and resistance loss gradually decrease with the blade spacing of curved plate increasing. Resistance loss and dehydration...
