New Mechanism of Saving Energy and Reducing Pollution in Burning Processing of Emulsified Oil Yuanyu Tian1, a, Yingyun Qiao1,b 1 Faculty of chemistry and chemical engineering ,Shandong university of technology, Qingdao,266510,China atianyy1008@126.com, bqiao_yingyun@126.com Keywords: Emulsification Oil, Combustion, Mechanism, Saving Energy, Reducing Pollution Abstract.
If dielectric constant is closer of two materials, their solubility is the better.
According to the new mechanism, the key to save energy and reduce pollution in burning process of emulsification heavy oil is to vaporize the liquid water rapidly into high temperature steam at the evaporation horizon.
The industrial scale test of the burning de-oiling hard asphalt-water slurry was finished in the medium-sized combustion furnace, which belongs to Institute of Engineering Thermophysics, Chinese Academy of Sciences.

The activation volume is a key to discuss the mechanism of diffusion and it can be obtained from the pressure dependence of the diffusion coefficient using the following relations.

Raman, ultraviolet (UV), and infrared (IR) spectroscopy methods for experimental study of viral materials are considered.
Preparing the research samples and having special materials is necessary to conduct these reactions.
Raman spectroscopy is one of the most often used in viral materials sensing and identification processes among optical methods [2–6,8,9,16,20–24,26,27,34].
From the viewpoint of viral materials research, two regions in the MIR (Mid-IR) spectrum are noteworthy.
This makes it possible to characterize the optical and electronic properties of various materials, including films, powders, monolithic solids, and liquids.
