Hi,
I just buy a diode bridge KBP210. but the output waveform isn't a rectified sinus waveform

please help me.

Thanks,

The picture is small but if I read it correctly, the peak to peak voltage is only ~400mV so you probably don't have enough voltage to drive the diodes into full conduction. As pointed out, you should put some kind of resistive load on the bridge output or you will see the effects of stray capacitance and the scope probes distorting the waveform.

Brian.
