透明工厂感受精致

德雷斯顿——被誉为“易北河上的佛罗伦萨”。这个曾被奥古斯特家族统治管理数百年的城市，每一座教堂，歌剧院和博物馆都记载着许多的历史。在二战期间，这座古城几乎被盟军的轰炸夷为平地。为了恢复当年的景象，许多慈善家们纷纷捐款，按照原貌对这座城市进行了重建，不仅对每一座建筑的外貌进行恢复，就连建筑用的材料也有许多是废墟中留存下了的。德雷斯顿还有一个引以为傲的方面，就是这里的手工艺品。价格不菲的钟表和瓷器，也真正体现了手工艺水平的价值。     

辉腾在这里诞生 详解大众汽车德累斯顿透明工厂

如果人们将一家汽车厂建造在市内，而不是在市郊；选择用玻璃，而不是用水泥；面向客户和参观者开放，而不是闭门造车；工厂里开设高档餐厅，甚至可以直接在车间里聆听音乐会……那么这一定是位于德累斯顿的透明工厂——大众汽车旗舰车型辉腾的诞生地。

Effect of injection condition and swirl on D.I. diesel combustion in a transparent engine system

The objective of this work was to investigate the effects of injection conditions and swirl on D.I. diesel combustion using a transparent engine system. The test engine is equipped with a common rail injection system to control injection conditions and to obtain split injection characteristics. A combustion analysis and steady flow test were conducted to measure the heat release rate due to cylinder pressure and the swirl ratio. In addition, spray and diffusion flame images were obtained using a high speed camera. The LII & LIS methods were also used to obtain 2-D soot and droplet distributions. High injection pressure was found to shorten ignition delay, as well as to enhance peak pressure. The results also revealed that the heat release rate in the premixed combustion region was markedly reduced through the use of pilot injection, while the soot distribution and the heat release rate in the diffusion combustion region were increased. The swirl effect was found to shorten ignition delay at certain injection timings, and to enhance the heat release rate in all experimental conditions.

咆哮的富人——宾利GT V8

赛道？宾利？这是一对看似不搭调的组合,难道有人会愿意忍受在老板座上被甩来甩去？除非,除非老板亲自掌舵,选择GTV8……     

大，尤可为

这年头行政级别轿车加长已经算不上什么新鲜事,鉴于国内消费者对加长车型表现出的慷慨,各个厂商的“加长车型”也是层出不穷。一贯以驾驶乐趣与对操控性毫不妥协的英菲尼迪貌似有些坐不住了,为中国市场推出了M系列的加长款。     

The Symbolic Significance of The Scarlet Letter

As a great romantic novelist in America in 19th century,Hawthorne was outstanding in handling the application of symbolism.The Scarlet Letter is Hawthorne's most important symbolic novel,which stands as the best work of Hawthorne and one of the indubitable masterpieces of American literature.This thesis aims at the exploration of the usage of the symbolism in the novel.It mainly discusses the deep symbolic significance of the scarlet letter "A" and the little pearl.The scarlet letter is the central symbol of the novel.Its symbolic meaning changes from 'adultery' to 'able',even 'angelic' in the novel.It also examines the symbolic meanings of little Pearl and some typical natural surroundings such as the jail,the forest,the rosebush and so on.
