巨砾

Now, at this angle of vision, there was nothing but the ground, far, far below, and jagged boulders set there like teeth.

现在，从这个角度看下去，底下只是遥不可及的地面，布满了犬牙交错的巨砾。

Boulder: also bowlder,a large rounded mass of rock lying on the surface of the ground or embedded in the soil.

Frequently occurring in mountain valley or sloping field, debris flow is one kind of solid-liquid two-phase flow which containing a mass of sand block and bowlder. It has many characteristics such as breaking out abruptly, time brevity, vigor ferocity, and fast calamity etc.

泥石流是产生于山地沟谷中或坡地上的饱含大量泥沙石块和巨砾的固液两相流体，具有暴发突然、历时短暂、来势凶猛、成灾快速等特点，是现阶段最活跃的地表动力地貌过程之一。

In this research, we try to find a more practical formula for calculating the impact force of boulders. We infer an academic formula from the elastic collision theory. Then, in the experiments, we simulate the impact by debris flow with mixed diameters in order to correct the result formula. We hope we can provide a reference for future slit dam design and debris flow prevention.

本研究目的为利用弹性体碰撞理论，推求出巨砾冲击力之理论式为基础，藉由实验方式，以混合粒径模拟土石流撞击梳子坝，来修正推算出之冲击力理论式，求得一个更符合实际撞击情形之巨砾冲击力计算式，期能对尔后梳子坝设计及土石流灾害防治问题，提供一设计之参考。

To his suprise, the rocks and boulders across the mountainside responded in kind: I HATE YOU...

Lakes spill from mountain gorges into frigid streams that work their way through pine-needled forest floors and over lichen6-covered boulders, providing water, food, or habitation to the white-tailed deer, the porcupines and moose, the rabbits, squirrels, raccoons, bobcats, beavers, a variety of fish and many kinds of birds that inhabit New England's wooded hills and mountains.

湖泊从峡谷奔流而出，变成一条条寒冷的小溪，流过布满松针的林地和长满青苔的巨砾，为生活在新英格兰大大小小青山之间的白尾鹿、豪猪、驼鹿、兔子、松鼠、浣熊、美洲野猫、河狸、各种各样的鱼以及许多种鸟类提供了水、食物和栖息地。

A tunneling machine for producing large tunnels in soft rock or wet, clayey, unconsolidated or bouldery earth by simultaneously detaching the tunnel core by thermal melting a boundary kerf into the tunnel face and forming a supporting excavation wall liner by deflecting the molten materials against the excavation walls to provide, when solidified, a continuous wall supporting liner, and detaching the tunnel face circumscribed by the kerf with powered mechanical earth detachment means and in which the heat required for melting the kerf and liner material is provided by a compact nuclear reactor.

&…一个在软岩石，或湿的、粘土状的、疏松的，或巨砾泥土中挖掘隧道的隧洞掘进机，用先进的以上升暖气流进行隧道核心分离，将边界切口熔入隧道面，同时通过使偏倚在隧道壁上的熔融物料在凝固时提供一个连续墙来支持衬垫，形成一个支持挖掘的墙壁；破碎在切口周围划了界限的隧道核心-用有动力的机械土地分离的方法，在隧道核心中，需要如此操作的热力以及衬垫物料由一个小型的核反应堆提供……&

Barely 6,000 feet, Mount Washington is the largest obstacle blocking this crush of weather, an atmospheric pinch point, a boulder in a fast moving stream that churns wind into white water.

华盛顿山仅高1900公尺，是阻挡辐合的最大障碍物；它是一个大气挤压点，好似急流中的一块巨砾，将风翻搅至泛白的水里。

San Diego, a sprawling city that spreads across 320 square miles (829 square kilometers) of hill, canyons, and shoreline, has a venerable history. Europeans first set foot here around 1542, 78 years before the Pilgrims landed at Plymouth Rock.

圣地亚哥是座幅员辽阔的城市，坐落于320平方英里(829平方公里)的山丘，峡谷和海岸之间，有着古老的历史。1542年左右，欧洲人第一次踏上了这块土地，这要比清教徒登陆普利茅斯海岸巨砾早了78年。
