Abstract: We did a survey of 550 nobel winners in Physics,Chemistry, Medicine between 1901 and 2011,and detailed analyzed the age of vinners, highest-degree age and the age when produce the prize-winning achievements. After study the nature of the Prize-winning achievements age ,we turned the most creativity ages for Nobel winners between 1901 and 2011 into average achievement ages for nobel winners between 1871 and 2004.The results showed that, in the past more than 110 years, there was no obvious causal relation between the changing tendency of the vinners，age and the age of Prize-winning achievements. But it should be noted that the extent of variation of prize-winning achievenments, age were varied little with subject disciplines. In other words , nobel winners, age of prize –winning achievements in chemistry and medicine presented stable increasing trend,6.40 years and 6.82 years on average respectively, yet in physics the average age increased slowly after slightly decreased ,but over trend was on the upswing for 2.95 years. The age of most creativity ages for noble prize in natural science is now between 44-47.
