恒等映射-
最后我们证明了B（H）上的在零点Jordan可导的线性映射是一内导子与数乘恒等映射之和。
Finally , we prove that every Jordan derivable mapping at zero point on B ( H ) is the sum of an inner derivation and a scalar multiplies identity mapping .

若d在I上是同态（反同态），则d是I上的恒等映射（R是交换的）。
If d acts as a homomorphism ( anti-homomorphism ) on I , then d is a identity map on I ( R is commutative ) .
