Especially, based on the fact that hydrocarbon migration would result in fractionation effects of methane carbon isotope, and that in the front of gas plume, methane carbon isotope would become lighter than that of the back, the isotopic information reflects the source of parent material and the geological and geochemical effects of its products [6-9].
The kerogen types are dominated by sapropelic and humic-sapropel, reflecting the hydrocarbon parent material with characteristics of bacteria and algae, and aquatic plankton marine organic matters [11].

The main pillar and the baseboard are made into circular shapes, and the main pillar of foundation and the principal material of tower leg have the same gradient.
The inner force of the principal metal tower of the inclined inserting excavated foundation is passed along the axis of the main pillar to the foundation baseboard, while the top of the main pillar only exerts a small horizontal component on the inclined material of the metal tower and very small bending moment on the whole foundation, greatly improving the stability of the foundation against overturning and effectively reducing the eccentric moment of horizontal component on the main pillar and baseboard of the foundation and lowering the foundation dimensions.

The vibrations depend on the material the workpiece to be machined is made of, its mass m1, stiffness coefficient k1 and damping coefficient c1, as well on the cutting tool (characterized by its mass m2, stiffness coefficient k2 and damping coefficient c2), and on machining parameters, such as: rate of tool travel v, rotational speed ω, number of teeth z, and depth of cut g.
The block "machining process" represents the nonlinear relationship between the cutting force and the specified cutting parameters (rate of tool travel v, rotational speed of the mill ω, width of cut d), properties of the material to be machined, tool geometry and the relative workpiece-tool motion.
