The dual structure of the complex fault depression in Songliao Basin and its geologic historic construction determined the existence of two sets of petroleum systems and their differences. The deep fault-depression group developed during Late Jurrasic to early Cretaceous and the particularity of the constructions of its inside sedimentary rock and volcanic rock determined the particularity of the natural gas enrichment conditions.

If her countenance and hair had rather a floury appearance, as though from living in some transcendently, genteel Mill, it was rather because she was a chalky creation altogether, than because she mended her complexion with violet powder, or had turned grey.

倘若她的面容，她的头发，颇有点面粉似的外表，仿佛她居住在一个超凡闲雅的磨坊里，那是因为她一生下来便全身上下具有白垩土的颜色，倒不是因为她靠搽蓝紫色的粉来修饰自己的肤色，也不是因为她的头发已经花白了。

利用现有的公认的晚白垩世有孔虫生物年代资料和复合剖面CS做线性回归分析，得到方程y =-

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
