    百年自然科学的波澜壮阔,尽在《〈自然〉百年科学经典》!

    《自然》百年科学经典(第二卷)(英汉对照本)收录并翻译?#26031;首?#21512;性学术期刊《自然》1931年至1933年期间发表过的103篇精华论文,再现了二十世纪三十年代短短三年期间各学科领域的飞速发展,展现了物理、化学、生物、天文、地球科学等领域的研究人员艰辛跋涉、不断探索的历史足迹。

    本册为地球科学分册。

    伦纳德·斯潘塞(1870.7.7—1959.4.14)英国地质学家,康沃尔皇家地质学会的名誉成员,于1936年至1939年担任大不列颠及爱尔兰矿物学会主席。

    Leonard James Spencer(7 July 1870 – 14 April 1959) was a British geologist. He was an Honorary member of the Royal Geological Society of Cornwall, and also a recipient of its Bolitho Medal.He was president of the Mineralogical Society of Great Britain and Ireland from 1936 to 1939.

    硅质玻璃极不容易发生化学反应,它所能经受的风化时间比很多其他物质?#23478;?#38271;。此外,其热膨胀系数也很低,不受温度变化的?#36299;臁?#36825;是在沙漠地区造成岩石?#28572;?#30340;一个重要原因。因此,玻陨石均保留在新近的沉积层中,如塔斯马尼亚的冰川沉积层,波希米亚、印度支那和菲律宾群岛的冲积层以及勿里洞岛的含锡砂砾层,在这些地方,缓慢的化学?#36136;?#22312;玻陨石表面形成了特殊的刻蚀面。而在澳大利亚沙漠表层发现的澳大利亚玻陨石则没有这样的刻蚀面,形态也更完整。所以澳大利亚玻陨石的形成时间比较晚。如果在发现澳大利亚玻陨石的地区进行航空勘测,也许能找到若干与大块铁陨石相关的陨石?#21360;?#32780;在其他地区,所有能证明陨石坑存在的证据可能?#23478;?#32463;因剥蚀作用而消失了,而铁陨石也被锈蚀掉了。

    Silica-glass is very resistant to chemical action and it will withstand weathering processes longer than many other materials. Also, with its very low coefficient of thermal expansion, it will not be affected by changes in temperature—a very potent agent of rock disintegration in desert regions. For this reason tektites are preserved in recent deposits, such as the glacial deposits of Tasmania, the alluvial deposits of Bohemia, Indo-China, and the Philippine Islands, and in the tin-gravels of Billiton, where by slow chemical corrosion they have acquired a peculiar sculptured surface. The australites found on the surface of the Australian deserts do not show this surface sculpturing and are more perfect in form. They are therefore of more recent origin. An aerial survey of the districts where australites are found would probably reveal the presence of meteorite craters with associated large masses of meteoric iron. In the other districts, all traces of the craters would probably have been obliterated by denudation, and the meteoric iron rusted away.
