岩壁

However, I would not necessarily recommend the climb as a first big wall. The well-established progression is to do first the Regular Route on the NW face of Half-Dome. If you are a big-wall beginner, you will find Paul Brunner's tips very useful.

然而，我并不推荐第一次就爬这大岩壁，按照级数先爬半圆顶西北面的一般路线，假如你是个大岩壁入门者，去找 Paul Brunner's tip 很有用。

Thereby, fractures always extend to the place with maximum compression stress, and finally a thin layer of palisades parallel to the free surface is formed.

运用断裂力学原理，分析了在岩壁附近压应力集中区内原生裂纹的亚临界扩展、贯通以及与自由表面的相互作用使裂纹沿最大压应力方向扩展，最终形成平行于自由表面的岩壁薄层的机理。

Not anyone can work on a rockface, using tools to bend it to his own idea of possibility.

现在任何人都可以上岩壁，只要用工具把岩壁改造成他心目中可以爬的样子就可以了。

This can be kind hard to do when the draws are resting on slabby stuff, as the rope is interfered with by the rock.

这在斜板地形较不顺手，因为快扣靠在岩壁，绳子会被岩壁妨碍到

This can be kind hard to do when the draws are resting on slabby stuff, as the rope is interfered with by the rock. It has a distinct advantage that you can easily "grab" the draw if you start to slip, and that you can use the pull on the draw to bring up slack out of the rope.

这在斜板地形较不顺手，因为快扣靠在岩壁，绳子会被岩壁妨碍到；不过，好处是当你有点要滑动时可以&抓住&快扣，且顺势带出贴紧岩壁的绳子。

I not only thought these the pure Productions of Providence for my Support, but not doubting, but that there was more in the Place, I went all over that Part of the Island, where I had been before, peering in every Corner, and under every Rock, to see for more of it, but I could not find any; at last it occur'd to my Thoughts, that I had shook a Bag of Chickens Meat out in that Place, and then the Wonder began to cease; and I must confess, my religious Thankfulness to God's Providence began to abate too upon the Discovering that all this was nothing but what was common; tho' I ought to have been as thankful for so strange and unforseen Providence, as if it had been miraculous; for it was really the Work of Providence as to me, that should order or appoint, that 10 or 12 Grains of Corn should remain unspoil'd,(when the Rats had destroy'd all the rest,) as if it had been dropt from Heaven; as also, that I should throw it out in that particular Place, where it being in the Shade of a high Rock, it sprang up immediately; whereas, if I had thrown it anywhere else, at that Time, it had been burnt up and destroy'd.

当时，我不仅认为这些谷类都是老天为了让我活命而赐给我的，并且还相信岛上其他地方一定还有。于是，我在岛上搜遍了我曾经到过的地方，每个角落，每块岩石边我都查看了一遍，想找到麦穗和稻秆，可是，再也找不到了。最后，我终于想起，我曾经有一只放鸡饲料的袋子，我把里面剩下的谷壳抖到了岩壁下。这一想，我惊异的心情一扫而光。老实说，我认为这一切都是极其平常的事，所以我对上帝的感恩之情也随之减退了。然而，对发生这样的奇迹，对意料之外的天意，我还是应该感恩戴德的。老鼠吃掉了绝大部分谷粒，而仅存的十几颗竟然没有坏掉，仿佛从天上掉下来似的，发生这样的奇迹难道不是天意又是什么呢？再说，我把这十几颗谷粒不扔在其他地方，恰恰扔在岩壁下，因而遮住了太阳，使其很快长了出来；如果丢在别处，肯定早就给太阳晒死了，这难道不是天意吗？

Downwards, where there exits light, there exist stairs. Upwards, where there exists light, there outstands crag. The ground is quite slippery because of the moisture inside the cave. Please be attentive: now we are beginning to climb up the stairs, please mind your step and be careful with the outstanding

讲解词Introduction speech：下方有灯光的地方就是有台阶的地方；上方有灯光的地方就是有岩壁突出的地方；由于洞内潮湿，所以地面较滑，请您注意；咱们开始上台阶，小心台阶和四周突出的岩壁。

This paper introduces the anchor design principle and calculation method of the crane girder on cliff wall in Huizhou pump and storage water power station,especially analyses the prototype observation and discusses the relating questions for the anchor design.

简要介绍惠州抽水蓄能电站工程岩壁吊车梁的锚杆设计原则和计算方法，重点对原形观测资料进行分析，并对岩壁吊车梁锚杆设计的有关问题作了探讨。

He had no ropes, bolts or pitons, and preferably no knowledge of the ascent except what he had gleaned from the ground, telling himself "Dude, there's some holds here, man."

他没有绳子，不用岩钉，也不喜欢实地了解岩壁各处的状况，一切准备工作都在地面上完成——他会一面观察岩壁，一面自言自语：&乖乖，这里有几个地方好抓，嗯！&

One of the foremost rock climbing areas in the world is Yosemite valley, and one of its premiere climbs is the ascent of El Capitan. While a number of routes are possible up the sheer face of this 3,000-foot granite monolith, the most famous remains the first: the Nose, straight up the Big Wall.

优胜美地谷是世界上最有名的攀岩圣地之一，其中最大的岩壁就是El Capitan；在这险峻的岩面有几条路线可以爬上这三千英呎的花岗石柱，最有名的一条就是Nose，直直的爬上这个岩壁。
