边石

Now by the light that Gelmir held above his head Tuor saw that the river began to go suddenly down a smooth slope into a great tunnel, but beside its rock-hewn course there ran long flights of steps leading on and downward into a deep gloom beyond the beam of the lamp.

此时借着Gelmir高举过头的灯光Tuor看到河流开始突然从平缓的斜坡泻入一条巨大的隧道，然而在它石凿的河道边有着一段段长长的阶梯，一路向下，没入灯光所不能及的深沉黑暗。

This paper introduces DDA, the basic mathematical principles, and presents applications in the analysis of rockfalls and slope stability problems.

在本篇文章将介绍DDA的发展渊源、基本的数理背景以及在比较特殊的落石与边坡稳定问题分析上的应用。

Torso from a statue of Amenhotep III(1388-1350B.C) depicts the king in a fight sleeveless cloak worn on his third hed-sed, ceremony of rejuvenation celebrated after two years after his death. Here Amenhotep III embodies both min, god of fertility, and taweret, patroness of birth. The king is thus identified as a creator God, capable of self-generation.

我至此开始适应了初进图书馆时茫然不知所措和看石头木头金块久了涌起的疲倦，发现散落在阶梯边展馆石棺石柱石牌门及各个雕像下正午憩着的美女们或雅致或神秘或艳丽，仿佛古代走出的神女，真正是一道生与死相映的风景。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
