卢梭 著黎星 译 译本序第一章第二章第三章第四章第五章第六章第七章第八章第九章第十章第十一章第十二章附录 译本序 在历史上多得难以数计的自传作品中,真正有文学价值的显然并不多,而成为文学名著的则更少。至于以其思想、艺术和风格上的重要意义而奠定了撰写者的文学地位——不是一个普通的文学席位,而是长久地受人景仰的崇高地位的,也许只有《忏悔录》了。卢梭这个不论在社会政治思想上,在文学内容、风格和情调上都开辟了一个新的时代的人物,主要就是通过这部自传推动和启发了十九世纪的法国文学,使它——用当时很有权威的一位批评家的话来说——“获得最大的进步”、“自巴斯喀以来最大的革命”,这位批评家谦虚地承认:“我们十九世纪的人就是从这次革命里出来的”。...
蚯蚓养殖技术2008-07-06 13:24蚯蚓养殖技术人工养殖蚯蚓工作是一项新兴的事业,它能作为畜、禽、鱼类等养殖的蛋白质饲料,可以利用蚯蚓改良土壤,培育地力,还能处理城市有机垃圾,化废为肥,消除有机废物对环境的污染。蚯蚓的用途很广,具有极高的经济价值。木片主要以红蚯蚓为例,介绍其养殖方法。红蚯蚓为正蚓科,爱胜蚓属,属于粪蚯蚓,其个体较小,一般体长90-150毫米,宽3—5毫米,性成熟时,平均每条鲜体重0.50克。体色为紫红色,尾部浅黄色。喜吞食各种牲畜粪,倾肥性强,适合于人工养殖。饲料的调制和发酵工作,是蚯蚓养殖的重要物质基础和技术关键。蚯蚓的饲料来源很广,凡是无毒的有机物质,如畜禽的粪便、各种植物器官、果皮、蔗渣、烂水果等,经过发酵腐熟后,均可作为蚯蚓的饲料。蚯蚓的生长繁殖,需要多种营养物质,主要的营养指标是碳氮比例。氮素饲料和碳素饲料不宜单独使用,必须适量搭配,使其比例调整在20—30...
作者:刘以林、于笑然系统与系统工程丁渭造宫与系统工程在我国古代的北宋(公元 960~1127 年)年间,有一天皇帝居住的皇城(今河南开封)因不慎失火,酿成一场大灾,熊熊大火使鳞次栉比、覆压数里的皇宫,在一夜之间变成断壁残垣。为了修复烧毁的宫殿,皇帝诏令大臣丁渭组织民工限期完工。当时,既无汽车、吊车,又无升降机、搅拌机,一切工作都只能人挑肩扛。加之皇宫的建设不同于寻常民房建筑,它高大宽敞、富丽堂皇、雕梁画栋、十分考究,免不了费时费工,耗费大量的砖、砂、石、瓦和木材等。当时,使丁渭头痛的三个主要问题是:1.京城内烧砖无土,2.大量建筑材料很难运进城内,3.清墟时无处堆放大量的建筑垃圾。如何在规...
佳能A系列数码相机(A720 IS)拍摄技巧1、点测光怎么用?点测光是从P档开始的手动档才有的测光方式,从AUTO开始的自动档没有。首先转到这些档,按相机最中间的那个功能键,出现调节菜单,然后用上下键调到测光处,再用左右键调到中间只有一个点的测光方式,按功能键(func)确定,然后半按快门键对准需要测光的部位到绿框内,快门保持半按,再按一下左上角那个+/-键,使得曝光锁定,然后松开快门,重新构图,最后就是按动快门。2、怎样手动调焦?当需要调整好焦距等待时机拍片时、拍微距需要精准调焦时、光线暗不好合焦时都需要用到手动调整焦距。怎么操作呢?在任何模式下都可以手动调焦,按动两次下方向键(一次是微距),就出现手动调焦指示了,用左右方向键调整距离与实际距离吻合就行了,就可以按下快门拍片了。...
Willard was four years older and a dozen years slower. He was generally a harmless sort who had never been in serious trouble and had never been seriously employed. Maybe an occasional fight with a night in jail, but nothing that would distinguish him. He called himself a pulpwood cutter, but a bad back customarily kept him out of the woods. He had hurt his back working on an offshore rig somewhere in the Gulf, and the oil pany paid him a nice settlement, which he lost when his ex-wife cleaned him out. His primary vocation was that of a part-time employee of Billy Ray Cob
绪论 绪论(1)我试图寻找出在两汉时期促成中国转向了农业经济的关键因素。因此有必要回顾一下汉之前,也就是战国时期的农业状况。战国时期农业发展最重要的成就是铁器的普及。近年来,在对古代聚落与墓葬的发掘中,出土了大量铁农具,在当时的冶铁遗址中还发现了许多铸造铁器的泥范。出土铁农具的形制在不同地域略有区别,并且被冠以了各种各样的名称,但大致来说,可分为锹、锄、镰、犁、刀、斧和凿等类。它们的形状和尺寸表明它们适用于农耕活动的不同阶段。考古报告中记录的锄和锹的数目,揭示了除草和碎土可能要占用农民在播种与收获之间的大部分时间。也就是说,战国铁农具是当时已经开始采用精耕细作的物证。铁斧与铁凿在伐木开辟农田方面效果显著,铁犁铧的出现则意味着耕作可能已开始用畜力牵引,这是在使用耒耜类农具进行手工操作基础上迈出的一大步。尽管铁农具比木石蚌制农具锋利耐用,但战国铁农具都还是用泥范铸造的...
This story takes place in an America whose history is often similar to, but often quite different from our own. You should not assume that the portrayal in this book of a person who shares a name with a figure from American history is an accurate portrayal of that historical figure. In particular, you should be aware that William Henry Harrison, famed in our own history for having the briefest presidency and for his unforgettable election slogan "Tippecanoe and Tyler too," was a somewhat nicer person than his counterpart in this book.

THE SENIOR partner studied the resume for the hundredth time and again found nothing he disliked about Mitchell Y. McDeere, at least not on paper. He had the brains, the ambition, the good looks. And he was hungry; with his background, he had to be. He was married, and that was mandatory. had never hired an unmarried lawyer, and it frowned heavily on divorce, as well as womanizing and drinking. Drug testing was in the contract. He had a degree in accounting, passed the CPA exam the first time he took it and wanted to be a tax lawyer, which of course was a requirement wi
Even before the events in the supermarket, Jim Ironheart should have known trouble was ing. During the night he dreamed of being pursued across a field by a flock of large blackbirds that shrieked around him in a turbulent flapping of wings and tore at him with hooked beaks as precisely honed as surgical scalpels. When he woke and was unable to breathe, he shuffled onto the balcony in his pajama bottoms to get some fresh air. At nine-thirty in the morning, the temperature, already ninety degrees, only contributed to the sense of suffocation with which he had awakened....

WIN in the Gulf An hour before dawn, in the Straits of Hormuz: a dark and dangerous time and place. The air was a chill mixture of sea and sweetness, giving no hint of the heat that would be generated once day took over. The massive Japanese-registered oil-tanker Son of Takashuni slowly ploughed its way towards the Gulf of Oman and parative safety. Its vast deck rolled gently; the tall superstructure, rising from the stem, looking like a block of flats, appeared to tip more violently than the deck because of its height. Every officer and rating aboard could feel a tight

我国自由锻液压机和大型锻件生产的发展历程 Post By:2008-5-31 22:43:08 [只看该作者]近几年来,国内大型自由锻一直处于一个高速发展时期,特别是2006年,全国各地掀起了一股大型自由锻设备投资建设热潮,各地纷纷上马大型自由锻液压机,据不完全统计,2007 ~2008年两年中,即将投产的在6000吨以上的自由锻液压机就有5台之多,而计划投资建设的更达到了10台以上。目前我国的大型自由锻液压机数量已居世界首位,我国的自由锻行业真的还需要这么多大型设备么?整个自由锻产业是供不应求,还是供大于求?现阶段对自由锻设备的投资是否盲目……早在1934年日本入侵我国东北以后,就在沈阳、大连建立机械厂安装了20MN、40MN自由锻水压机生产大锻件。1945年日本战败以后,这些锻造设备被友军拆走了。由中国人自已设计制造自由锻液压机和生产大型锻件的时间不长,仅有50多年的历史。现在回顾我国设计制造自由锻液压机和生产大型锻件的历...
