具有强吸收的非Newtonian扩散方程的行波解及交界面

本文我们首先找到了有限行波解,然后研究了具有强吸收项的非Newtonian扩散方程交界面的短时间行为. 我们将表明交界面的短时间行为依赖于初始浓度, 准确的说,找到了初始浓度的一个临界值,用它可区分交界面是热前面还是冷前面.     

The test pulse line ion accelerator in Lanzhou

To accelerate intense, short pulsed heavy ion beams to the energies of interest for studies of high energy density physics and warm dense matter, the Pulse Line Ion Accelerator (PLIA), of which the axial acceleration gradient can achieve several MeV per meter with realistic helix parameters at very low cost, was developed in recent years. A simple prototype of PLIA for a proof-of-principle experiment called the Lanzhou Test PLIA was designed and constructed at the Institute of Modern Physics in Lanzhou, and the test result matches the calculated result well. The pattern of the axial electric field Ez and the velocity of the traveling wave were simulated by CST.
