求翻译：测量小灯泡电阻的实验中,如果第一次测量时灯泡两端的电压等于灯口上的标定电压,以后几次测量时电压逐次降低,直到看不到灯泡发光,对比这样得出的几值,你能发现什么?尝试做出解释,然后设计实验证实(或否是什么意思？

Experiment of measuring the resistance of a small light bulb, if the voltage across the lamp when the first measurement is equal to the calibration voltage on the light mouth, after several measurements, voltage successive lower, until you do not see the light bulb, the contrast is so drawn several

In the experiment of measuring small resistance bulb, bulb voltage at each end of the lamp measured for the first time on the calibration of voltage, voltage measured several times successive decrease in the future, until you do not see the bulb light, contrast so that several values, you can find o
