破坏时期

Guizhou took a national minority lives together backward province, after the founding of the nation the secondary education development has experienced the early years of the new nation restoration and the development,"the Great Leap Forward" and the adjustment time undulation,"the Great Cultural Revolution" destruction, reform and open policy big development winding course.

贵州作为一个少数民族聚居的落后省份，建国后中学教育的发展经历了建国初期的恢复与发展、"大跃进"和调整时期的改革与调整、"文化大革命"的大破坏、改革开放后大发展的曲折历程。

Based on the previous research on the portal crane administration, one standpoint put forward in this paper is idea that is on the foundation of reliability in this paper, two viewpoints take shape when reason is analyzed, that is fatigue break and appearing the flaw that will extend. What is the fatigue break?(this phenomenon is always happen in some place),the fatigue is that board appears apophysis and concave when the board is pressed .so that the board ability of bearing the weight of load will descend. Second , the board appear the flaw that the flaw extends in the some place of board one reason is that the machine works too long, so the board ability of bearing the weight of load will decline.

本论文建立在已有的港口装卸机械管理的研究基础之上，进一步提出了以可靠性为基础的港口装卸机械的管理思想，已有的研究表明，港口机械设备破坏主要由于两个原因，第一是稳定性问题，特别是构件的局部稳定性，所谓稳定性是指：在板的平面内，板受到平行于板面的压力作用，使板发生隆起、内陷等凹凸不平的结果，从而使板受载能力减弱；第二是结构出现疲劳裂纹及其扩展，这是由于设备长时期运行，而造成设备某些部位出现裂纹并得以扩展，使设备承载能力下降。

Since Neogene period, oil-gas reservoirs was readjusted and destroyed due to tectogenesis.

新近纪以来主要是已形成的油气藏重新调整和破坏时期。

Yet American house prices are falling faster than during the Depression, petrol is more expensive than in the 1970s, banks are collapsing 破坏, the euro is kicking sand in the dollar's face, credit is scarce, recession and inflation both threaten the economy, consumer confidence is an oxymoron and Belgians 比利时人 have just bought Budweiser,"America's beer".

但是，美国房价正以比大萧条时期更快的速度下跌，石油比20世纪70年代更加昂贵，银行倒闭，欧元在美元面前飞扬跋扈，信用缺失，衰退和通胀都威胁着经济。比利时人刚收购了被称为"美国的啤酒"的百威啤酒，这与消费者信心形成矛盾。

And the results indicate that the principal stress directions in study area are mainly NE-SW, and the second substage tectonic twist made the direction deflect from North to East, but the primary direction changed little; tectonic activities during the O〓～S～D stage is some violent, most of the area are under high stresses status, and rock fracture degree is correspondingly higher, as coinciding with the drill cores observation, i.

通过数值分析，模拟了塔中Ⅰ号断裂带和塔中45井三维模拟区O〓灰岩的构造应力场和应变场，结果表明：研究区主应力方向为北东～南西向，第二期的构造扭动使其由北向东发生了一定的偏转，但总的方位变化不大；O〓～S～D时期，塔中地区构造运动较强，研究区大部分处于高应力状态，岩石破裂程度较高，而岩芯观察结果也证实了这一结果，即O〓灰岩地层中早期形成的构造结构面比较发育，单个结构面的规模也较大；C～P时期，岩石的破坏程度较早期有所提高，主要表现在两个方面，一是各局部区岩石的破坏程度普遍有所提高；二是各个级别破裂区的分布范围相应地扩大了；研究区应力分布表现出明显的不均匀性，特别是剪应力，无论是O〓～S～D时期，还是C～P时期，都有很大的差异性，特别是在小断层的端部，剪应力比较集中，而且在断层的两盘，剪应力方向和大小都变化极快。

In this article, we discuss the destroyed process of forest resources on the basis of history, and it is illuminated by the characters which timberwork had showed in several dynasty such as Tang, Song, Yuan, Ming and Qing.

森林资源的破坏有多种原因，为大众公认的是垦荒屯田。笔者以为还有一重要因素即人类的建设活动对木材的大量需求。本文以史为据分析了各时期森林资源的破坏过程，并结合唐、宋、元、明、清几个时代木结构表现出的特征给予说明。

1976 " The Great Cultural Revolution " convulsion period, be disturbed badly and national economy progress is destroyed, manufacturing efficiency and economic benefits drop, but because save indefatigable effort of people completely, there still is certain development eclectically in hard music. 1978 11 of the party 3 in since plenary meeting, bring order out of chaos, hold high Deng Xiaoping academic banner, hold to the main line of the party, insist to be a center with economic construction, hold to 4 basic principles, emancipatory thought, renew an idea, deepen reform, expand open, accelerate economic system and the change that economy grows way, initiated since founding a state, the richest lease of life is mixed the new period of vigor.

在旧社会遗留下来的军疮百孔、支离破碎的基础上，初步建立了门类比较齐全的国民经济发展体系，各项建设事业都取得了令了瞩目的成就。1966—1976年的&文化大革命&动乱时期，国民经济发展受到严重干扰和破坏，生产效率和经济效益下降，但由于全省人民的不懈努力，在艰难曲折中仍有一定发展。1978年党的十一届三中全会以来，拨乱反正，高举邓小平理论旗帜，坚持党的基本路线，坚持以经济建设为中心，坚持四项基本原则，解放思想，更新观念，深化改革，扩大开放，加快经济体制和经济增长方式的转变，开创了建国以来最富有生机和活力的新时期。

Then the sustainable development of Qitai artificial oasis was discussed. Researches showed that the oasis development has gone through three phases: The first was harmonic stage before the middle of 20, the oasis developed according to water resources. The second was unharmonic stage from 1950's to 1980's because of unreasonable policies, that is cultivated area enlarged rapidly and water resources exploited backward. As a result, land output was lower, and environment destroyed heavily. The third stage is after 1980's, the new fragile balance between oasis and its environment was established on the base of the more and more ground water utilization.

研究认为奇台人工绿洲人地关系发展经历了三个阶段：第一阶段是20世纪50年代以前，&以水定地&的相对协调发展时期；第二阶段是20世纪50-80年代人地关系发展失衡时期，人工绿洲迅速扩张，水资源开发滞后，耕地因缺水灌溉而成为低产田，环境破坏严重，人地发展失衡的原因是政策因素；第三阶段是20世纪90年代以来人地关系脆弱平衡时期，决定其平衡的因素是不断增加的地下水开采量。

Now though, you can only see the glittering scenes in old photographs, the triumphant angels, the exquisite Madonna drawn over the shadow of the iconoclasts' plain cross.

但是现在你只能在旧相片里看见这些动人的景象，胜利的天使、优雅的圣母像取代了圣像破坏时期的十字架。
