We give some conditions under which mappings are derivations on operator algebras in chapter 2 and 3 . generalized jordan derivations and generalized jordan triple derivations on prime rings and standard operator algebras are introduced and studied in chapter 4 在第四章我们给出了广义jordan导子和广义jordantriple导子的定义，研究了素环和标准算子代数上的广义jordan导子和广义jordantriple导子。
