Abstract: As an important national resource, the growth and development law of Engineering and technical talent needs to be clearly recognized. Inspired by the older generation of science workers like Zhao Hongzhou and Jiang Zhenhuan, it carries out quantitative analysis on issues such as "best age district" and "peak age" that facing to technological inventions, and summarizes the characteristics of age distribution of major technological invention output. It shows that the age curve of major technological invention output is in?accord with?Weibull?distribution, but the specific parameter values and the shape have their own peculiarities. The result has both enlightenment significance and reference value on the management and development on engineering and technical talents.

摘要： 工程科技人才是我国重要的资源，其成长和发展规律需要被清晰认识。在赵红州和姜振寰等老一辈科学学工作者的启发下，面向技术发明的“最佳年龄区”、“峰值年龄”等问题进行定量分析，总结出重大技术发明产出的年龄分布特征。研究表明，重大技术发明产出的年龄曲线符合威布尔分布，但具体的参数值与形状有其特殊性，这对我们开展工程科技人才的管理和开发工作具备启示意义和参考价值。
