0 Q" h/ g3 X. O( A0 A8 I6 h恩,我们这边用示波器,将一欧电阻接在电源两端,用示波器测试两端电压,示波器可以持续监视电压波动,可以很准确的测量出一秒末的电压 " the total battery voltage does not exceed 2,5 V, measured 1 s after a 1 Ÿ resistor has 8 e* c _) x7 B6 H6 j
been connected between the supply terminals of the toy, with any current limiting device

"the total battery voltage "是一秒末的电压吗?
