粒子模拟表明，可以在一些简单的假设下再现外部间隙。该模拟仅包括第一原理，即麦克斯韦方程组、具有辐射阻力的相对论运动方程以及电子-正电子对的创建。我们还认为Y点（赤道的开闭边界）很可能是等离子体加热和加速的地方，因此会引起高能发射。沿相反方向电流分界线的死区位于中纬度地区，它将外部间隙和极帽加速器分开。
It is shown with a particle simulation that the outer gap can be reproduced under a few simple assumptions. The simulation includes just the first principles, namely Maxwell's equations, a relativistic equation of motion with radiation drag, and electron-positron pair creation. We also suggest that the Y-point (the open-close boundary in the equator) is likely to be a place of heating and acceleration of plasma, and therefore it would cause high-energy emission. The dead zone along the separatrix of the oppositely directed current is found in the middle latitude region, which separates the outer gap and the polar cap accelerators.
