基因作为遗传学的一个核心概念,其意义在不同的时期有着明显的差异。基因概念的这种差异是依赖特定语境隐喻地发生转移的。文章通过分析基因概念的转移,说明了隐喻正是在这种概念转移中渗入科学。之后,文章以DNA双螺旋模型为重点,分析了其构建过程中的隐喻思维以及隐喻的方法论功能——发明功能及表征功能。 Gene as a core concept of genetics, its significance in different periods have obvious differences. This difference in gene concept is based on metaphorical context shift. By analyzing the transfer of gene concept, the article shows that metaphor is infiltrating science into this concept transfer. Afterwards, the article focuses on the DNA double helix model, analyzes the metaphorical thinking and metaphorical methodological functions in the process of its construction - the invention function and the representation function.
