upper inversion的意思|示意

An inversion of velocity structure of crust and upper mantle by using converted PS wave and multiwave PPP etc, is reported in this paper.

本文是研究利用天然地震PS转换波及PPP等二次波到时资料反演地壳上地幔速度结构的尝试。

This paper reported the results of inversion esophagectomy without thoracotomy for 26 cases of upper esophageal cancer, 5 cases of cardiac cancer.

本文报告我院非开胸食管内翻拔脱术治疗食管上段癌26例。贲门癌5例的治疗结果，并对此术式治疗食管癌。

Finally, the characteristics of shear velocity distribution in the crust and the upper mantle obtained by inversion has been discussed.

讨论了反演所得地壳与上地幔的横波速度分布特征。
