跪求《千年一叹》的读后感?（简略版）600～800字左右
　　够简略了把,这是原创哦　　利用假期时间,我阅读了余秋雨先生的《千年一叹》,这本《千年一叹》,说是一本书,倒不如说是余秋雨先生的游记.这篇篇游记,让我们与先生一起神游古希腊,古巴比伦,古埃及曾经辉煌的文明.秋雨先生仿佛这些沉睡了千年的文明的知音,带我们一层一层掀开它们神秘面纱,展示了先生渊博的学识.也为我开拓了新的视野.很想沿着他行走的路线,到世界各地去看看,那也就不枉此生了.　　全书的阅读,不断勾起了我的种种疑惑,一个个问题浮生于脑海之中.　　究竟是人类创造了文明,还是文明孕育了人类?昔日的文明发源地现在却在向世人展示着它的脆弱与无能为力.漫天飞扬的泥沙,赤脚如密林的失学儿童,眼神空洞的乞讨者,这还是文明的产物么?几千年前文明从这里开始,几千年后文明从这里已经走上了衰败的道路.我们又用什么去衡量所谓的文明程度呢?是看这个地方有多少林立的高楼么?我不得而知.　　历史,究竟是何物?它究竟能影响多少?我一时间理不清头绪,也无法理清.的确,历史已经成了历史,它以文字,画卷的样子悄然流逝,已经过去了,而且永不回头.但是人之所以为人,是因为他们有自己的文化,自己的历程.如果没有了历史,我们就像是哑巴,无从诉说；如果没有了历史,我们就像是一阵风,没有始没有末,没有了目的没有了方向.历史是家,是广阔天地里的一座朴素坚硬的石头房.没有修饰,没有点缀,是我们远航时挂念的故都,是流浪天涯浪子的根.　　在看了这本书后,我真的由衷的感谢我们的祖先,为我们伟大的祖国而骄傲.早在秦始皇时便统一了文字,使得中国历史活了下来,不象埃及的历史,变成了“木乃伊”,现在的人们面对一大片一大片黑黝黝的古文字却完全不懂何意；而一部印度的普通历史,却也要中国人的著作来填补和修订.我国五千年的文化历经千辛,却也完整地保留了下来,而不像两河流域许多国家,只剩下了一些颓垣残壁和一段辛酸的回忆.　　品味整本书的字里行间,就仿佛亲身游历了那些历史悠久的国度,了解着这些国度的种种文化,让我叹为观止.　　以前总固执的以为,伊朗女人是很悲哀的.她们被黑袍裹着,失去了追逐美丽的自由.女人应当是属于缤纷的色彩的,而伊朗的女人只拥有黑色,她们周身都被黑色束缚,不禁让一些大谈个性解放的人对伊朗政府的规定愤然.但是,一位伊朗女士却这样告诉余秋雨先生：黑袍可以给人安静,让心灵也随着黑稠的飘动而沉淀,我们觉得它很美.　　品读完全书,仿佛我的心也随着余秋雨到处走了一遭,感觉好像我也来了一个千年一叹.让我的心灵也沉淀了千年来历史文明的古韵,让我感受到了这样一种美丽与圣洁.中医八千字的毕业论文怎么写啊_百度知道

Abstract: In the modern construction of concrete plays an important role, but the concrete cracks are more common. This article analyzes the causes of concrete cracks is proposed measures to control and prevent the cracks, and curing of the concrete problems early.
Key words: C conservation
First, micro-cracks in concrete
Cracks in reinforced concrete structures is to work with. Rather, the hardening process of concrete in the condensation, there exist micro-cracks, because the concrete in the cement and aggregate changes in temperature and humidity conditions to produce the volume of non-uniform deformation, and they bonded together and can not free-form deformation, so the formation of mut Once the cement and aggregate constraint between the stress is greater than the bond strength and tensile strength of cement itself, will produce micro-cracks.
Second, the causes of concrete cracks
Concrete cracks are the result of the development of micro-cracks. Concrete cracks for many reasons, for its part, considered to be bound by the deformation of concrete due to tensile stress than the material's sake.
1. Optional inappropriate material defects and the formation of cracks. Expired cement, aggregate excess mud, with active SiO 2 , high alkali cement, limestone aggregate, cement hydration heat and so on.
2. Construction of mishandling the formation of defects and cracks. Plastic concrete sink, was the top bar of the resistance, the formation of cracks alo concrete vibration is not dense, there cellular, easy to form the starting point for a variety concrete mixer, transit time is too long, so that water evaporation, causing low slump concrete pouring, making the concrete volume in the m rapid drying of concrete made when the initial curing of concrete contact with the atmosphere in the irregular early form removal, concrete not yet established sufficient strength to impose its own components in the actual gravity load, prone to all kinds of stress cracks.
3. Because of the force components, deformation and crack formation of defects. C beam concrete shrinkage and tem plate of concrete shrinkage and tem in reinforced concrete, the tensile stress is mainly borne by the reinforced concrete is exposed stress. In plain concrete or reinforced concrete on the edges if the tensile stress within the structure there shall be to rely on concrete to bear. General design requirements in both the tensile stress does not appear or appear only very small tensile stress. However, the maximum temperature of concrete in construction to the operation of the cooling period of steady temperature, often caused by a large concrete internal tensile stress.
4. Because of environmental factors affect the formation of defects and cracks. Mainly temperature and humidity changes, the brittleness of concrete and uneven, as well as unreasonable structure, failure of raw materials (such as alkali-aggregate reaction), template deformation, differential settlement of foundation. Concrete dissolution cycles many times by the freeze, the stress generated in the concrete, and promote the development of existing cracks, loose structure, surface cracks, surface spalling or overall collapse.
Third, measures to control and prevent the cracks
1. Of cement, water, aggregate, admixtures, reinforcement materials, the improper selection of the formation of cracks on the entry of raw materials must be in accordance with national standards for strict inspection and acceptance of the approach to prevention, where the unqualified use of defective materials shall be , or reduce t of these have occurred due to improper selection of materials defects or cracks in concrete produced must be observed in detail for the long term (due to some problems take a while to find), carefully identify its causes and Quality of the problem, study and formulate their treatment and reinforcement. This is because once occurred due to improper material selection, quality problems, often with the universal reason.
2. As long transport time of concrete mixing, pouring too fast, the vibration is not real, it is improper construction joint, move the template the formation of cracks and other reasons can follow the &concrete order& strict implementation of concrete mixing, transport, pouring, vibration pound set and the old concrete construction joint connection. Templates, and form removal, and conservation requirements to prevent, the occurrence of such cracks in the component have been, but also distinguish the type of component, component of the force characteristics of the site where the cracks and the extent of serious cracks were commonly used in concrete cracks reinforcement measures or by filling concrete, steel anchor reinforcement, and even stick steel reinforcement, prestressed reinforcement remedial measures.
3. Due to dry weather, the initial maintenance is not good, the early cold concrete and large changes in temperature and humidity of the cracks were used to enhance the natural hardening process of concrete Results conservation, conservation of heat storage, the use of air-entraining agent to uniform distribution of air bubbles inside the concrete, measures such as temperature expansion joint repair reserved. Severe cold components, some should be removed, some should be reinforced before being used.
4. Because the components have to withstand loads too wide cracks, reasonably designed to prevent the emerg cracks have been too broad component appears to be reinforced by strengthening measures.
5. The foundation of unequal settlement of large cracks too broad and reasonably in the design of the building when checking in the use phase of the settlement to prevent the emergence of these cracks, these cracks have occurred on the structure, to use ground-based control measures proper handling of the foundation, then building the structure reinforcement measures adopted to solve.
6. On the environmental conditions and changes in the use of the crack occurred, according to different properties to different control measures, such as:
(1) the use of temperature and humidity changes during the formation of cracks, usually difficult to eradicate, to adopt the protection of reinforced concrete measures to reduce atmospheric humidity changes of the comp
(2) The cracks resulting from repeated freezing and thawing, in addition to defects and damage has been formed in part to be reinforced or reinforced, but should add insulation on the co
(3) The corrosive medium in the resulting defects and damage a large area, in addition to corrosion and damage should be removed by the site to be reinforced or reinforced, shall use the acid water glass slag cement concrete or concret
(4) damage due to earthquake seismic structural measures should b have been generated by the earthquake damage is not severe earthquake damaged buildings may refer to repair and reinforcement of the solution to the problem.
In addition, temperature control and improved from the constraints of the two aspects. Used to improve the aggregate gradation, with a dry hard concrete, mixed with mixture, add air-entraining agent or a plasticizing agent measures to reduce the amount o water when mixing concrete or gravel with water cooling to reduce the concrete hot days when the pouring of concrete pouring to reduce the thickness of h in the concrete laying pipes, pass into the co set reasonable removal time, the surface heat when temperatures plunged to avoid dramatic concrete surface t Construction of Concrete Blocks and long-term exposure to surface or thin-walled structure, insulation measures taken in the cold season.
Measures to improve the constraints are: a reas to avoid excessiv reasonable arrangements for the construction process, to avoid the excessive height and long-term exposure to the side.
In addition, to improve the performance of concrete and improve the crack resistance, enhance conservation, to prevent surface shrinkage, in particular, to ensure the quality of concrete is very important to prevent fractures, special attention should be avoided through the cracks, appears to restore its structural integrity is difficulties, so the construction should be to prevent the occurrence of cracks in the main cross-cutting.
Fourth, early curing of concrete
Practice shows that cracks in concrete common, most of the surface cracks of different depth, mainly because of the temperature gradient caused by the sudden drop in temperature in cold areas are also easy to form cracks. Therefore, the concrete surface of the insulation to prevent early cracking is particularly important. From the viewpoint of thermal stress, thermal insulation should meet the following requirements:
(1) prevent the concrete and the concrete surface temperature difference between inside and outside the gradient, to pr
(2) to prevent the concrete super cool, should try to try to make concrete the construction period of not less than the minimum temperature on the stability of the temperat
(3) to prevent cold and old concrete to reduce the constraints between the new and old concrete. Early curing of concrete, the main purpose is to maintain proper temperature and humidity conditions in order to achieve the effect of two aspects, one of the concrete from adverse temperature and humidity deformation of the invasion, to prevent the harmful shrinkage and shrinkage. On the one hand to smooth the cement hydration in order to meet the design strength and crack resistance.
V. Conclusion
Cracks in concrete above the relationship between the various effects of the theory and practice discussed, although the academic cracks in the concrete and calculation methods are different theories, but for specific advice for prevention and improvement measures more unified, but in practice of effects are good, concrete construction depends on our seeing much comparison, more analysis after problems, and more sum up, with a variety of preventive treatment measures, concrete cracks are completely avoidable.
