rise time的用法和样例：
例句
- Thus, even large values of capacitance shunting the input will have negligible effect on rise time.
所以，即使并联在输入端的电容很大，其对上升时间的影响也很小。 - Due to the high degree of voltage amplification, this stage regenerates the voltage swing and the rise time of the incoming signal.
因电压放大的高倍数，这一级一则改变输入电压的摆幅，二则改变引入信号的上升时间。
