决定性的因素是这种区分是没有根据的样本离散多时间，但它是一个物理作用，使用户会看到一个充满活力，低噪声加速度信号。

The decisive factor is that the differentiation is not based on a sample over a discrete time period, but is a physical effect, so that the user sees a dynamic, low-noise acceleration signal.

切换动态系统是一类重要的混合动态系统，它是由几个连续时间子系统或离散时间子系统及作用在其中的切换规则构成的。

As an important class of hybrid dynamical systems, a switched system is composed of several continuous time subsystems or discrete time subsystems and the switching signal among them.
