查询词典 sediment-covered

Groundbreaking research by two french geophysicists promises to shed some light on the mystery.using 80 metres of deep sea sediment core, they have obtained measurements lots of magneticfield intensity that span 11 polarity reversals and four million years.the analysis reveals that intensity appears to fluctuate with a clear, welldefined rhythm.although the strength of the magnetic field varies irregularly during the short term, there seems to be an inevitable longterm decline preceding each polarity reversal.when the poles flip―a process that takes several hundred thousand years―the magnetic field rapidly regains its strength and the cycle is repeated.

答案为d。这一题目是根据上下文判断词意的题。flip的意思是&快速翻转&，它所在的句子的意思是&当两极互换――这一过程需要上万年的时间――磁场会很快重新恢复它的强度，新的一轮循环又开始了。&因此在四个选项中： a.decline的意思是&拒绝；变小、变弱&，b.intensify的意思是&变得更强烈、加剧&，c.fluctuate的意思是&涨落、波动&；d.reverse的意思是&使反转、倒退、颠倒&，例如：writing is reversed in a mirror。写出来的字在镜子里是颠倒的。d的意思与flip最接近。

Results indicate that the observed salt fluxes under the two wind conditions show a marginal difference. Under the steady wind condition, a DBL with a constant thickness of 3.5 cm is observed right above the deposited sediment. The molecular diffusion is found to be the dominant mechanism for salt transport within the DBL. The latter can suppress the hydrodynamic enhancement on the exchange of substances between deposited sediments and overlying water.

研究结果表明，在稳定风场条件下，沉积物－水界面处存在厚度约3.5cm的扩散边界层，有风条件下的界面盐分交换通量略大于无风时的通量；分子扩散是边界层内盐分运移的主要机制，扩散边界层对沉积物盐分释放具有阻滞作用，并且边界层越厚，阻滞效应越显著。
