How ths multivibrator works? I can't understand.Because its pulse not given to base of transistor.

The transistor is in the common base configuration. In this configuration, the input is at the emmiter.

so what happened to the transistor when a pulse is coming.if it turn on ?(revers bias or forword bias)

When a negative pulse arrives at the emitter, its voltage is lower than the base voltage, so the transistor is forward biased.
