时间是客观的,为了反映时间的流逝,总用周期性振动的周期和次数的乘积来计量。作为计时工具之一的摆钟,它的摆作周期性振动,它指针的“跳进”又跟摆的振动同步,即指针因“跳进”积累的“走时”跟摆的振动次数N成正比,t∞N。因此,摆钟准确与否,就决定于摆的振动次数准确与否,实质上即决定于摆的周期T准确与否。 Time is objective. To reflect the passage of time, it is always measured by the product of the period and the number of times of periodic vibration. The pendulum clock, which is one of the timekeeping tools, is periodically oscillated, and its “jump in” is also synchronized with the pendulum vibration. That is, the pointer “acceleration” accumulates the “travel time” and the pendulum vibration frequency N Proportional, t∞N. Therefore, whether the pendulum clock is accurate or not depends on whether the number of oscillations is accurate or not. In essence, it depends on whether the pendulum cycle T is accurate or not.
