    Abstract: Liquid density is one of the most important governing physical parameter of the fluid flow. Generally, oil density measured at standard conditions (14.65 psia and 60 °F) via Density Meter. Since there is a remarkable difference between calculated density from compositional analysis and measured one at standard conditions. So it is of great importan... Show More

    Abstract: In the present paper, X-ray photoelectron spectrum (XPS) is used to reveal the surface texture, main elements and occurrence mode of different-density-level sample coal of Fenxi County. The experimental results demonstrate that: (1) there is an extremely low content of nitrogen in the sample coal; (2) carbon mainly exists in the form of C-C and the... Show More
