The absorption spectra from 0.2 to 1.7 THz of five water-acetone mixtures, whose concentrations are 0%,25%, 50%, 75%, and 100%, has been investigated by THz time-domain spectroscopy(THz-TDS). The result indicates that of acetone solutions with different concentrations have different absorption for THz radiation, which is analyzed and attributed to the variation of the hydrogen bond. Furthermore, we also find the absorption of the water-acetone mixture almost linearly increases with the increase of water concentration in the THz range.

单断断陷湖盆发育过程中,由主断层控制的幕式差异沉降活动将导致可容空间重新分配。水体发生重新分配过程中,湖盆中各点的相对湖平面变化并不统一,由此产生的准层序组也不一致。本文提出了断陷湖盆中可容空间转化枢纽的概念,建立了可容空间转化枢纽的数学计算模型,讨论了可容空间转化枢纽的分布位置,以及对其存在的各种影响因素。位于缓坡带可容空间转化枢纽下部,相对水体深度变深,形成退积型准层序组;反之,则变浅,形成进积型准层序组;稳定期形成加积型准层序组。可容空间转化枢纽的提出,对于定量认识单断湖盆相对湖平面不均一变化,以及对于隐蔽性油气藏的勘探都有一定的参考意义。
