Application of Peng-Robinson equation of state for calculation of liquid and gas viscosities of hydrocarbons;

Based on the mode of thinking of systematology,the new geological theory of rotations of the galaxy and the earth and their relationship with earth hydrocarbons is put forward in this paper.

Total Coloring Conjecture of Planar Graphs Without l-cycles;

A note on total colorings of planar graphs without 4-cycle and adjacent 3-cycle;

On the 3-choosability of Plane Graphs with a Girth of 4 and without 7- and 8- cycles;

Borodin and Raspaud proposed a conjecture which claims that every plane graph without 5-circuits and adjacent triangles is 3-colorable.

In this paper we consider the circuit of minimum total weight problem.

This article provides a number of new ways to access the famous conjecture on the double covering of graphs by circuits which is still open for more than 20 years in posing a number of conjectures which look to have more approaches than what has been used for the double cover conjecture by circuits.

Vertex-distinguishing edge-coloring of graphs with distance between path and circle less than 3 and 4;

This paper narrated and proved an minimal spanning tree algorithm which requires no consideration of circles.
