| 摘 要： | 竖直平面内有一圆轨道与斜轨道光滑连接，让不同的物体（如小滑块，小圆球，小圆柱体）从斜轨道h高处无初速释放，要使其落在圆轨道上指定点（如轨道最低点），对它们的初始高度，脱离轨道的位置及飞行时间进行了理论计算并解释了其原因。

| Abstract: | There are a loop and a ramp connected in a vertical plane where the ramp is tangent to the lowest point of circle. Different objects ( a block, a sphere, a cyclined) are started on a ramp higher than center of circle and then released. They are expected to land on the special point (e.g. the lowest point). Their starting height, leaving tract position and flying time are calculated and the causes are analyzed. |
