This paper establishes a vulnerability and comprehensive competitiveness model, and uses TOPSIS and PCA to estimate resource-based cities' vulnerability and comprehensive competitiveness in Central Plains Economic Region, and evaluates their relation through linear function. Their vulnerability has undergone first ascending and then descending tendency stage generally during 2006 to 2016 temporally, with lowest vulnerability in Puyang, Bozhou, Suzhou, Sanmenxia and Hebi spatially. Their comprehensive competitiveness has experienced an overall ascending but local descending tendency, with Jincheng, Changzhi, Huaibei and Luoyang seating on top 4 spatially. According to the linear analysis, vulnerability is negatively related to comprehensive competitiveness in Luoyang, Pingdingshan, Puyang, Nanyang, Suzhou, Bozhou, Handan and Xingtai, positively in Hebi, Jiaozhuo, Sanmenxia, Jincheng, Yuncheng and Huaibei.

This paper is focusing on the coupling coordinated development relation between the upstream and downstream industries within mineral resources, establishes coupling coordinated model which is used to analyze mining and processing coupling coordinated development level based on energy, ferrous metals, non-ferrous metals and industrial minerals, in order to discuss the variance and evolution of coupling coordinated relation of mineral resource industry in Henan province, with the resulting showing an S-shaped coupling coordinated degree, coordinated index rising to 0.623 in 2016 from 0.23 in 1999, low but slow-rising during 1999 to 2004, low but fast\|rising during 2005 to 2007, indicating a consistent coordination, high during 2008-2016, implying a stable coordination. 

This paper, from the principle of microscopic CT technology, analyzes its application in porous structure and penetration mechanism, which can precisely, directly, harmless, perspectively scan cores, quantitatively analyze and identify rocks, minerals, and display porosity, dynamically show a reconstructed perspective projection data, and clearly reflect the internal microscopic texture and oilgas migration rule in reservoir, and directly acquire reservoir physical data, and establish a 3D model of the rock. This technology works well in oilgas exploration, and directly shows the reservoir property, which will surely play a key role in petroleum geology. China shall intensify study on and import this kind of equipment. 
