摘　　要：采用形变的相对论平均场模型对rp（快质子俘获）过程核的基态性质进行了系统研究，计算了质量数A=60-100，N=Z的偶偶核的平均结合能，均方根半径，单中子和单质子分离能．并与已知的实验数据进行比较，发现二者能够较好地符合，肯定了相对论平均场理论对rp过程核研究的可靠性．我们的计算结果可为未来rp过程的实验研究提供一些理论参考．The ground state properties of the even-even N= Z nuclei with mass number A= 60-100 along the rp-process （rapid proton capture process） path have been systematically calculated in the deformed relativistic mean-field （RMF） theory with the force parameter TMA. The binding energies per nucleon, nuclear radii and separation energies are analyzed and dis- cussed in detail. It is found that theoretical results are in good agreement with experimental data. The reliability of the RMF model for the N= Z nuclei along rp-process path has been tested in this research. The results of these nuclei above will be use- ful for future experimental researches of rp-process.
