Conclusion PESS has typical MR manifestations that show empty sella clearly. MRI should be regarded as the best way to diagnose PESS.
结论原发性空蝶鞍综合征具有典型的MR I表现，MR I可清晰显示空蝶鞍，MR I应作为原发性空蝶鞍综合征的首选影像学检查方法。
Firstly, for each reaction system, all molecular geometries were fully optimized on respective ground state and the lowest excited state PESs by high-level quantum chemistry calculation methods.
首先，采用高精度计算基组，对不同反应路径在不同自旋态势能面上的各驻点的几何构型进行了优化。
