有时候重负荷的iPhone使用会导致电池消耗快得荒谬。
There are times when heavy iPhone use can drain the battery ridiculously fast.
适合常重负荷工况的二轮、三轮摩托车使用。
Suits the constant weight load operating mode two turns of, three turn of motorcycles uses.
对负荷增大，但磨擦系数无敏感变化，因此重负荷下，磨擦系数极小，并且长期保持精度不变，可得机械使用寿命长期保持。
On the load increased, but not sensitive to changes in friction coefficient, so heavy, the friction coefficient is extremely small, and the same long-term accuracy can have long-term mechanical life.
