To test the idea, Merrison and colleagues sealed samples of quartz sand in glass flasks and used a machine to tumble them over and over.
为证实这一观点，梅里逊和同事们将一些石英砂样品封装入玻璃烧瓶内，然后用一机械装置将这些烧瓶反复翻滚。
The sample came from the remote Pilbara region of Western Australia, a site called Strelley Pool, where the microbes, after dying, had been finely preserved between quartz sand grains.
化石样本来自澳大利亚西部偏远的皮尔巴拉地区一个叫斯特雷利池的地方。在那里，死后的微生物在石英砂和沙砾之间被完好的保存下来。

Most sand is made of quartz, a hard silicon crystal.
Bishop's sandpiper poet, there in your handout, is obsessed with the mere details of experience, those sand grains, quartz grains.

Using large-scale interfacial shear apparatus,a series of direct shear tests between geogrid and sand were performed under cyclic load. The influence of normal cyclic load characteristic on shear property of geogrid-quartz sand interface was studied.
采用大型结构面剪切仪进行了循环荷载作用下土工格栅与砂土的直剪试验,研究了法向循环荷载特征对土工格栅与石英砂界面剪切特性的影响。
