On the basis of plan form and crosscutting relationship of the faults, two kinds of tectonic systems were developed in Wu-Xia area, one was strike north-east, and another was strike east-west, the first was developed early and control the structural framework of Wu-Xia area, after that three times longitudinal compress action was happed. According to the intensity of tectonic deformation, The Wu-xia faulted zone from north to south can be divided into the thrust faulted belt, the fault fold belt and the monocline belt. from east to west have three regulatory faults, Wuerhe fault fold belt, Wuxia thrust faulted belt and Xiahong fault fold belt. Base on that 9 secondary structural unit can be divided.Structural accommodation zone and the distribution of reservoir strata have intimate business connection. Usually, Structural accommodation zone was the source zone of arenaceous sediment. The Wu-xia faulted zone have 3 kinds of structural accommodation, concordant approach, concordant overlap and concordant colinearity.

首先研究本区的构造特征，根据断裂的平面形态及相互切割关系，乌夏地区发育两种构造体系：北东向构造体系和近东西向构造体系，前者形成早，控制了该区的构造格局，晚期有3次近南北向挤压作用叠加；乌夏地区南北根据构造变形的强度不同分为冲断带、断褶带、单斜带，东西由于横向调节断层的存在分为乌尔禾断褶区、乌-夏冲断区和夏-红断褶区，进一步划分为九个次级单元；构造调节带与储集层的分布关系密切，通常是大量富砂质沉积的源区，乌夏地区发育三种类型的构造调节带：同向接近型、同向叠覆型和同向共线型。

The Place I was in, was a most delightful Cavity, or Grotto, of its kind, as could be expected, though perfectly dark; the Floor was dry and level, and had a sort of small lose Gravel upon it, so that there was no nauseous or venemous Creature to be seen, neither was there any damp, or wet, on the Sides or Roof: The only Difficulty in it was the Entrance, which however as it was a Place of Security, and such a Retreat as I wanted, I thought that was a Convenience; so that I was really rejoyc'd at the Discovery, and resolv'd without any Delay, to bring some of those Things which I was most anxious about, to this Place; particularly, I resolv'd to bring hither my Magazine of Powder, and all my spare Arms, viz.

虽然在洞里没有光线，但这却是一个令人赏心悦目的最美丽的洞穴。地上干燥平坦，表面是一层细碎的沙石，所以不会有令人厌恶的毒蛇爬虫。洞顶和四壁也十分干燥。这个洞穴唯一的缺点是入口太小，然而正是因为进出困难，才使它成为一个安全隐蔽的地方，而这也正是我千方百计寻求的庇护所。所以，这个缺点于我来说反而成了一个优点。我对自己的发现真是欣喜万分，决定立刻把我所最放心不下的一部分东西搬到洞里来，特别是我的火药库和多余的枪支，包括两支鸟枪和三支短枪。

As she looked at Warrington's manly face, and dark, melancholy eyes, she had settled in her mind that he must have been the victim of an unhappy attachment.

每逢看到沃林顿那刚毅的脸，那乌黑、忧郁的眼睛，她便会相信，他一定作过不幸的爱情的受害者。

Maybe they'll disappear into a pothole.

也许他们将在壶穴里消失
