【 摘 要 】

In understanding the nucleosynthesis of the elements in stars, one of the most important quantities is the reaction rate and it must be evaluated in terms of the stellar temperature 𝑇, and its determination involves the knowledge of the excitation function 𝜎(𝐸) of the specific nuclear reaction leading to the final nucleus. In this paper, the effect of thermonuclear reaction rates to the pre-main sequence evolution of low mass stars having masses 0.7, 0.8, 0.9 and 1 M⊙ are studied by using our modified Stellar Evolutionary Program.
