You dont need a big gas hog to drive one person to work in the morning, he says. 他说,如果你早晨是独自一人开车去上班,就不需要开很费油的大车。
Then the tectonic stress field and strain field of the two stages are simulated by using finite element method, and their genetic relationships to the above mentioned large flat uplift and big gas fields in the central Ordos Basin are studied. 然后利用有限单元法分别模拟了盆地这两个演化阶段的古构造应力场和应变场特征,进而探讨它们与盆地中部大型平缓隆起及大气田的成因联系。
Three years ago, the US energy department was forecasting the US would become a big net gas importer. 3年前,美国能源部预测,美国将成为天然气净进口大国。
But big greenhouse gas emitters are protected at present by the absence of a global carbon price and, given the dismal record of curbing emissions to date, border taxes are an idea well worth considering again. 然而,由于缺乏全球碳定价体系,温室气体排放大国现在正受到袒护。考虑到全球迄今在限制碳排放方面的糟糕记录,碳边境税真的是一种很值得再次考虑的想法。
