Query: Control of black hole evaporation?   Contradiction between Hawking's semi-classical arguments and string theory on
the evaporation of black hole has been one of the most intriguing problems in
fundamental physics. A final-state boundary condition inside the black hole was
proposed by Horowitz and Maldacena to resolve this contradiction. We point out
that original Hawking effect can be also regarded as a separate boundary
condition at the event horizon for this scenario. Here, we found that the
change of Hawking boundary condition may affect the information transfer from
the initial collapsing matter to the outgoing Hawking radiation during
evaporation process and as a result the evaporation process itself,
significantly.
