We reached a beautiful grotto, whose entrance was almost hiden by the vine. 我们到达了一个美丽的洞穴,洞的进口几乎被藤蔓遮掩著。
The particulates have more acidic pollutants with strong acidity and have the corrodibility to grottoes. 细粒子中有较多的酸性污染物并比粗粒子酸性强,这些细粒子对石窟有侵蚀作用。
The development of technology and improvement of test methods are the hopes for solving the periodization of grottoes. 科学技术的发展、科学测定方法的进步和完善,是解决石窟分期问题的希望所在。
A grotto (Italian grotta and French grotte) is any type of natural or artificial cave that is associated with modern, historic, or prehistoric use by humans. When it is not an artificial garden feature, a grotto is often a small cave near water and often flooded or liable to flood at high tide. The picturesque Grotta Azzurra at Capri and the grotto of the villa of Tiberius in the Bay of Naples are outstanding natural seashore grottoes.
