"You can see where lava has flown into wet sand and then next to it where it's flown over dry land, and that gives us an indication of when different things were happening millions of years ago," Mateus explained.

马泰乌斯解释说：「你可以看见火山喷发的熔岩流入潮湿的沙地，再流到邻近乾燥的沙地上，这可以提示我们，千百万年前不同的事何时发生。

1Arid-subarid palaeoclimate was helpful for mechanical weathering of source rocks and torrent forming;(2) The combination of source rocks and their occurrence were liable to cause mechanical breakdown of rocks and form mudflow,(3)There was a considerable height difference along the border of the basin,(4) The density of subaqueous mudflow was 2.4-2.7g/cm3;(5)There was a high rate of accumulat...

认为本区沙三段时期满足重力流的形成条件，主要表现在六个方面：(1)干旱-半干旱的气候环境有利于母岩的机械风化和山洪的形成；(2)母岩的组合及其产状容易发生机械破碎，形成泥石流；(3)盆地边缘地形高差悬殊；(4)高密度的水下泥石流；(5)堆积速率大；(6)水深位于半深湖以下。

本研究在阳西海域划出两个预选倾倒区，对它们进行了水深和海流测量，通过数值模拟方式研究了该海域的流场、标识点的漂移路径和悬沙的迁移扩散，并探讨了疏浚物倾倒对海洋环境的影响。

It has been proven that, from the propagation process of the tidal waves and wave energy rates, the whole radial sandbanks area is controlled by the progressive tidal wave in the south and the rotational standing tidal wave in the north.

另外还研究了辐射沙脊群海域的余流及余流量的分布，发现在潮流沙脊两侧存在平面余环流，余环流将有利于泥沙在脊顶沉积，与潮流沙脊的维持发育密切相关。

The roles and economic significance of four rodents (Phodopus roborovskii,Dipus sagitta,Meriones meridianus and Crivetulus barabensis) inhabiting in Erdos sandland were evaluated from the point of energy flow and material cycle.

摘 要：以鄂尔多斯沙地中的4种主要啮齿动物小毛足鼠、三趾跳鼠、子午沙鼠和黑线仓鼠为对象，从能流和物质循环的角度对其在生态系统中的地位、作用及其经济意义进行了定量评价。

It is thought that the channel bay line evolution processes can be divided into four stages. The first stage is soon of the sea level stable when the bayhead mountines are eroded and developed abrasion geomorphy and the productive materials were transport into the bay deposition by the tidal current and wave current and were reworked into gravel dams. The second stage is characterized by the fluvial output sediments and eroded sediments mixed deposition in channel bay and developed marine accumulation plain and sand riges in the plain under the wave reworked. The third stage developed clay silt marine accumulation plain under the action of the channel current and the wave action is very limited. The fourth stage is marked by human being reclaim which result in the channel bay filled and evoluted into a strait arce coast.

文章认为，峡道海湾的充填经历了四个阶段，第一阶段以峡道海湾湾顶山体在波浪作用下产生的侵蚀物质充填为主，发育了海蚀崖、海蚀洞、海蚀穴等侵蚀地形和湾顶砂砾石堤等堆积地形交替的峡道湾顶地貌，第二阶段以河流输出物质和峡道湾岛屿、礁石侵蚀物质在潮流作用下向峡道湾输运，由潮流和波流共同沉积为特征，发育海积平原，部分粗颗粒泥沙在波浪的改造峡，发育平原沙堤，第三阶段以河流输出物质为主，在涨落潮流搬运下进入峡道和峡道湾沉积，在峡道湾中发育以淤泥质粉砂为主要物质的海积平原，第四阶段以人类围涂造田为标志，加速峡道湾的充填过程，使峡道海湾最终趋于夷平，形成顺直均衡的弧形海岸。

Speaking frankly, the day before yesterday, when you were making silane, the temperature of the hydrogen stream you used to blast off silica sand was too high and caused a super silicification reaction.
