Due to the weak construction technical standard and the lack of appropriate building materials, the small town was short of overall design.
Thus residential building system cannot be systematized, residential complete technology level is completely at a disadvantage position and Often becomes the "colony” for city to transfer lag materials and technology.

Most hydrocarbons in subsurface soil are characterized as immiscible and form a liquid phase separate from water and/or air [1], named as non-aqueous phase liquids (NAPLs), therefore their migration in soil and groundwater are not the same as general dissoluble materials.
