随后斗轮机构及回转机构运行开始取料，变幅机构配合取料作周期性动作。

Afterward the bucket-wheel organization and the swiveling mechanism movement starts to take the material, the amplitude organization matches the conjunction material to make the periodic movement.

该模型的连续性证明的表达式“周期性波动”和“商业周期”，虽然动作既不恒定的持续时间也不恒定的长度。

The continuous character of this model justifies the expressions' cyclical fluctuations' and 'business cycle' although the movements have neither constant duration nor constant length.
