Uniqueness theorem of meromorphic functions sharing one value

Sharing value with weight is an important thing in the uniqueness theory of meromorphic function.In 2005 Zhou Houqing proved a theorem about the uniqueness of meromorphic function,we consider if we can weak the condition CM to weight using the idea of sharing value with weight so as to get a better conclusion.We use the idea of weight to study the uniqueness of meromorphic function sharing one value.The conclusion improved the result of Zhou Houqing.
