用静电加速度解释近月质子速度分布
Near-lunar proton velocity distribution explained by electrostatic acceleration
摘要：
近月尾迹中平行离子速度的观测结果近似等于外部太阳风速度\emph{can}，可以用解析静电膨胀模型在不确定性范围内解释。经常使用的一维模型是不充分的，因为它没有考虑到月球的球形。然而，应用最近的推广到三维的解决方案，沿特征预测更高的速度，并可能足以解释SARA对Chandrayaan-1航天器的观测。
英文摘要：
The observation of parallel ion velocity in the near-lunar wake approximately equal to external solar wind velocity \emph{can} be explained within uncertainties by an analytic electrostatic expansion model. The one-dimensional model frequently used is inadequate because it does not account for the moon's spherical shape. However, application of a more recent generalization to three-dimensions of the solution along characteristics predicts higher velocities, and is probably sufficient to account for the SARA observations on the Chandrayaan-1 space-craft.
