In order to analyzes the soil deformation mechanism under the impact load of the step-bit, the finite element model of impact and displacement drilling with down the hole hammer is established on the basis of adopting Drucker-Pager yield criterion, taking soil as DP materials and simulating the drilling process by applying the impact load on soils.

为了分析阶梯钻头冲击挤密作用下土体的变形机理，将土体视为DP材料，服从Drucker-Prager屈服准则，通过钻具与土体之间的接触以及施加冲击载荷来模拟钻进过程，建立了潜孔锤冲击挤密钻进的有限元模型。

But if you can abseil down the mountain, canyon down the ravine, kayak down the raging torrent, scuba dive across the lake, pot-hole through the sewage system, and climb up to my balcony to get me spoiled.then I'm going to be impressed, and you're going to be pleasantly surprised that I could do the same!

如果你可以从高山上速降，沿江而下，淌越激流，潜过湖水，经由下水道，攀上我的阳台，来将我宠爱。如果你打动了我的心，你将会惊奇地发现，我也会为你做同样的。

The semi-submersible ocean deck-barge is one of the new ships emerged in recent years. Submerging-floating technique is employed for loading and unloading. The barge is mainly used in salvage operations, transporting sunken ships, small and medium-sized ships or large structures such as dredgers and oil drilling platforms.

半潜式海洋甲板驳是近年来发展起来的一种新型船舶，它主要采用浮上—浮下方式进行装卸作业，可用于运输沉船，打捞救助辅助作业以及运输各种中小型船舶和大型结构物，如挖泥船，钻井平台等。

Before you realise, it's fish-feeding time and your guide will supply you with all the bread you'll need to attract the attention of hoards of hungry fish, only too eager to feed from your hand before experiencing a unique snorkelling adventure through the varied habitats of a dazzling coral reef.

从玻璃船底往下看，你可以把绚丽的海底世界尽收眼底。您还可以给鱼儿们喂食，亦可在五光十色的珊瑚礁丛中体验一次独特的浮潜经历。

Podozolization and gleying are two distinctive soil forming processes under different environment conditions.

灰化作用和潜育作用是两种在不同环境下显著区别的成土作用。

However, in the hands of a good captain and crew, at least a few Mings have proved capable of sneaking around quietly.

但是至少有几艘明级在训练有素的指挥官和船员的操控下有能力静静潜行。

This rocks have high content of organic carbon, low content of chloroform"A"and potential hydrocarbon-forming which indicates the original hydrocarbon source rocks of lower Cambrian were better oil-forming rocks, but the actual oil-forming potential are poor.

研究表明，该套烃源岩有机碳含量高，氯仿沥青&A&含量和生烃潜量较低，说明本区下寒武统原始烃源岩是最好的生油岩，由于演化程度过高，现实的生油潜能较差。

I looked at the left a bit and found this view. At that very moment, I almost jumped into the water to join the two snorkelers to explore the underwater scene.

我稍微往左一瞧，就发现这个景色，就在那时，我几乎想一跃而下跳进水中，加入这两个浮潜客去探索海中的景象。

Snorkelling equipment usage is free and the kit is of good quality and you can take canoes/pedaloes for free.

浮潜工具租用是免费的，而且最重要的是质量很好，你可以免费划船，只能有船长陪同的情况下才能划筏。

In the whole market development, there are also a lot of places: 1、decoration personnel, decentralization, spare no good management system, not by most decoration of professional training and lack of effective knowledge in the cases of housing decoration, the quality of the crisis, cut corners, crude abuse of engineering quality is low, no guarantee after-sale, etc. 2、in the industry, many designers unspoken rules, and for his own benefit subcontracted, the owner of this link purchase materials, a rake-off extraction. 3、decoration materials, the source of confusion, very small workshop of small companies selling certificates of poor quality material, often without the use of security, and short, etc.

在整个市场的发展中，也存在很多不规范的地方：1、装修人员的业余化，分散化，没有良好的管理系统，打多数装修人员没有受到过良好的专业培训，在缺乏有效的知识的情况下，往往对住房的装修质量带来不小的影响，偷工减料，粗制滥共工程质量低下，售后无保障等等。2、行业中潜规则，不少的设计师和施工者，为了自身的利益，在业主购买材料的这一环节中，提取着回扣。3、装修材料的来源非常混乱，小作坊，无证件的小商家兜售的材料，往往质量差，无保障，使用年限短等等。
