论文摘要
我们在分析圆形山丘上的滑雪者分析求解了微分方程，并在山坡或轨道上赋予环路轨道上的粒子，并带有一个动态摩擦系数$μ$。对于每个问题，我们确定二维参数平面中的确切“相图”。
We solve analytically the differential equations for a skier on a circular hill and for a particle on a loop-the-loop track when the hill or track is endowed with a coefficient of kinetic friction $μ$. For each problem, we determine the exact "phase diagram" in the two-dimensional parameter plane.
