Dear Mayor:

I'm a middle school student. I'm writing to tell you something aroud us. Nowadays, there are many left-behind children whose parents work away from their hometowns. Most of them are from the coutryside, you know, they have many problem. They are always lonely and stressed out because they are short of their parents' love. At the same time, they are easy to make mistakes even do some thing against the laws, because they're short of their families' care.

How to solve their problems? In my eyes, the government can set up a parents school for these children on holidays, you can organize" hand-in-hand" activity to call on more people to help them. You can also raise money to donate to these children. As the song says:"If everyone gives their love, the world will be better." It's very important for us to pay more attention to these children if we want to build a harmonious society.

Best wishes to you!

㈡ 求助,请高手帮忙翻译一下下面的几段文字

Over 20 years, scientist and the engineers start resolve Shanghai to sink to decline a problem, adopted restriction to pump water at that time of some measure, Shanghai strengthenned these measures in 2003.Request an each dozen an one mouthful a deep well, all want official permission.
Currently, mining groundwater the quantity has already had a control, the capacity of every year is 100,000,000 sign a square rice, pass these restrictions, city hall in Shanghai and related sections in the joint effort now.With decelerates the speed that Shanghai descends to sink further.
Because 20 centuries second half leaf to excessively open up of the land, big 兴 the Anne 岭's south forest edge has already retreated 200 kilometers at least, the big 兴 is one of Chinese main LIN2 QUs, there is much waterfalls in its south region, very in keeping with farming.
In the past 50 years, a great deal of forest of this regions encounter to the breakage, is open up to become farmland, according to big 兴 environmental protection the expert say, 200 kilometers of just retreat to distance in big 兴 south of keep to calculate.
The big 兴 LIN2 QU's area descend, cause the soil erosion and the river bed dried up, some places in Inner Mongolia, plant ever and thickly quilt, have already disappeared currently.A lot of rivers are already a year river often, now indeed decline the water but dried up because of lack.
In the past decade, Shanghai with equally sink to decline about 16 millimeters speed annually, with since 20's in 20 centuries, center city area in Shanghai about 600 district of the square kilometers have already equally descended to sink 2000 millimeter, some places even come to a 3000.
As early as 1921, the geologist discovers Shanghai is descending to sink, the expert thinks consistently, a main reason that sinks to decline is a groundwater to mine excessively, moreover, the fast increment of the city center skyscraper is also one of the reason that Shanghai sinks to decline.
Though this region forbids to open up in great quantities now, some farmers try to extend their farmland still, so forest still Be being eroded graally, the national forest management bureau will launch inquisition, looking up a responsibility person who result in now situation.
Pay attention to increasingly to the environment problem along with the international society, the environmental protection instry develops rapidly within the scope of world, the flourishing and national environmental protection instry increases annually 100 divide 6, but in East Asia with pulled this numeral of a little bit beautiful developing countries to then exceed 100 divide 10.
The environmental protection instry of China also in the booming development, since recent more than 10 years, the Chinese government promotes environmental protection strongly, in this kind of case, the environmental protection instry development is quick, having already become national economy an importance to constitute part.
The Chinese environmental protection instrial structure unbalance, the environmental protection service, the environmental protection proct, the market of[with] the environmental protection technique and the environmental protection funds needs a further development.The Chinese environmental protection instry contain huge potential, but have to adopt some measure to come to well exertive this kind of potential.
After big dam in Yangtse gorges starts retain water, fluid matter in Yangtze River has no occurrence variety.The wreath 卫 worker already from the water level river bed top clearance 1,990,000 ton garbages, 1,980,000 ton instrial waste, and 1500 ton dangerous odd-come-short, and carried on disinfection to 5,000,000 all toilets in the square meters.
The environment learns an estimate, fluid matter in Yangtse gorges still will keep national x-rated level, however start soar along with the reservoir water level after retain water, the water current speed reces slowly, river the by one's own sweep of the water ability will have to descend.Therefore, reservoir in Yangtse gorges still faces a huge challenge.
Decade in aftertime, China will invest about 400 忆 renminbis in the database area of Yangtse gorges, about 忆 US$48.The cent criticizes to build up 150 processing factories a processing factory with 170 city garbage, anticipate can handle this region 100 divide 85 above waste water and the garbages.
First stage, heavy celebrate to have already set up 19 dirty water processing factories with 13 garbage processing factories, they win of greatly part of will throw in movement before the reservoir water level soar to 135 meters.Locate the database area about 1000 severity pollution business enterprises to have already been close moreover

㈣ 纳米材料在各个行业中的应用

(一)力学性质
高韧、高硬、高强是结构材料开发应用的经典主题。具有纳米结构的材料强度与粒径成反比。纳米材料的位错密度很低,位错滑移和增殖符合Frank-Reed模型,其临界位错圈的直径比纳米晶粒粒径还要大,增殖后位错塞积的平均间距一般比晶粒大,所以纳迷材料中位错滑移和增殖不会发生,这就是纳米晶强化效应。金属陶瓷作为刀具材料已有50多年历史,由于金属陶瓷的混合烧结和晶粒粗大的原因其力学强度一直难以有大的提高。应用纳米技术制成超细或纳米晶粒材料时,其韧性、强度、硬度大幅提高,使其在难以加工材料刀具等领域占据了主导地位。使用纳米技术制成的陶瓷、纤维广泛地应用于航空、航天、航海、石油钻探等恶劣环境下使用。
(二)磁学性质
当代计算机硬盘系统的磁记录密度超过1.55Gb/cm2,在这情况下,感应法读出磁头和普通坡莫合金磁电阻磁头的磁致电阻效应为3%,已不能满足需要,而纳米多层膜系统的巨磁电阻效应高达50%,可以用于信息存储的磁电阻读出磁头,具有相当高的灵敏度和低噪音。目前巨磁电阻效应的读出磁头可将磁盘的记录密度提高到1.71Gb/cm2。同时纳米巨磁电阻材料的磁电阻与外磁场间存在近似线性的关系,所以也可以用作新型的磁传感材料。高分子复合纳米材料对可见光具有良好的透射率,对可见光的吸收系数比传统粗晶材料低得多,而且对红外波段的吸收系数至少比传统粗晶材料低3个数量级,磁性比FeBO3和FeF3透明体至少高1个数量级,从而在光磁系统、光磁材料中有着广泛的应用。
(三)电学性质
由于晶界面上原子体积分数增大,纳米材料的电阻高于同类粗晶材料,甚至发生尺寸诱导金属——绝缘体转变(SIMIT)。利用纳米粒子的隧道量子效应和库仑堵塞效应制成的纳米电子器件具有超高速、超容量、超微型低能耗的特点,有可能在不久的将来全面取代目前的常规半导体器件。2001年用碳纳米管制成的纳米晶体管,表现出很好的晶体三极管放大特性。并根据低温下碳纳米管的三极管放大特性,成功研制出了室温下的单电子晶体管。随着单电子晶体管研究的深入进展,已经成功研制出由碳纳米管组成的逻辑电路。
(四)热学性质
纳米材料的比热和热膨胀系数都大于同类粗晶材料和非晶体材料的值,这是由于界面原子排列较为混乱、原子密度低、界面原子耦合作用变弱的结果。因此在储热材料、纳米复合材料的机械耦合性能应用方面有其广泛的应用前景。例如Cr-Cr2O3颗粒膜对太阳光有强烈的吸收作用,从而有效地将太阳光能转换为热能。
