Q: What is acceleration, velocity, and displacement?
问:什么是(地震)加速度、速度和位移?
A: Acceleration is the rate of change in velocity of the ground shaking (how much the velocity changes in a unit time), just as it is the rate of change in the velocity of your car when you step on the accelerator or put on the brakes. Velocity is the measurement of the speed of the ground motion. Displacement is the measurement of the actual changing location of the ground due to shaking. All three of the values can be measured continuously during an earthquake.
答:(地震)加速度是地面震动速度变化率(单位时间内的速度变化的多少),就像当你驾驶汽车加油或刹车时你的汽车速度改变率一样。速度测量的是地面运动速度。位移测量的是由于地震造成地面真实地点变化。这三个量值在地震过程中都可以连续记录。
下面的图表示了一次地震加速度、速度、和位移随时间变化的曲线。三者之间从左到右为积分关系,从右到左为导数关系。
