In this paper, a theoretical model for grey synthetic evaluation of seismic liquefaction of sands is established based on exploration of main factors which have great influence upon liquefaction.

通过研究砂土液化的主要影响因子，建立了砂土液化的灰色综合评判理论模型，并成功地将该理论模型应用于实际工程中。

Crude oil, or its substitutes, will be produced for decades, but at an increasingly expensive tariff, both in terms of cost and energy, as it is sourced in the form of a heavy, sour (high-sulphur) material, or in synthetic form from tar-sands, shale and coal.

By then many refiners will have expanded and upgraded to take not only heavy crude but also synthetic crude from Canada's oil sands.

For their calculations, the two assumed that where there was a gap between demand and conventional supply it would be filled with synthetic fuels, first with tar-sands oil and later with oil from coal and shale. (According to high-end estimates, coal and oil shale could together yield some ten trillion barrels of unconventional crude.) They then calculated what the impact would be on global carbon-dioxide levels.
