但是呢，却都去买18i，然后配上各种豪华的配件和内饰。 |

需要定向结晶技术才能铸出来.
[ 转自铁血社区 http://bbs.tiexue.net/ ]
这也是最大难题,这是涡扇发动机,节油条件下能进行超音速最理想的发动机.没有这涡
扇那就可喝油的涡喷发动机了......
五大常任理事国中我们是唯一个没有撑握定向结晶技术的国家.
落后是铁定的事实....
你对机床工具行业了解多少?就来一句德国进口中国磨床.

即使人家进口了,也是图意你这产品便宜.由于是廉价劳动力干出来的所以才便宜.
中国机械工具行业与德,日差70年,与美国差小70年.
硬件:轴承,行星齿轮减速箱,齿条,丝杠,导轨
电气硬件:触点开关,无处点开关,光栅尺,编码器,PLC,CNC电脑,对刀仪,主电机,伺服电机
液压硬件:电磁阀,旋转接头,压力继电器,各种密封圈

发帖数: 10422 | 4 美国应该只有 28i 2.0T 一种。发动机和 F30 328i 一样。国内还有 18i，20i，25i
等。28i 油耗 9.2/6.4L/100km，即 25/36 mpg。也基本和 F30 328i 一样。
除了新发动机，X1比GLK足足轻了550磅（250kg）。可能也是它省油的原因之一。不过
，GLK可能使用了很多高强度肛材，它的车身强度变态的高（特别是侧面和车顶）。在
很多看不见的地方，奔驰确实对得起它的价钱。
我很想知道 X1 轻量化以后，车身的强度如何。由于尚未进入美国市场，还没有 IIHS
的测试数据。我估计能达到 Q5 的水平就不错了。和 GLK 比几乎不可能。
你说的那种像大便一样的棕色？我觉得红色，蓝色，橙色也不错。 |

拿下了。肯定比搞二夫 R 便宜。 |

1Five days later the high priest Ananias went down to Caesarea with some of
the elders and a lawyer named Tertullus, and they brought their charges
against Paul before the governor. 2When Paul was called in, Tertullus
presented his case before Felix: “We have enjoyed a long period of peace
under you, and your foresight has brought about reforms in this nation.
3Everywhere and in every way, most excellent Felix, we acknowledge this with
profound gratitude. 4But in o... 阅读全帖 |

发帖数: 6791 | 12 An Illustration From Marriage
1Do you not know, brothers—for I am speaking to men who know the law—that
the law has authority over a man only as long as he lives? 2For example, by
law a married woman is bound to her husband as long as he is alive, but if
her husband dies, she is released from the law of marriage. 3So then, if she
marries another man while her husband is still alive, she is called an
adulteress. But if her husband dies, she is released from that law and is
not an adulteress, even... 阅读全帖 |

1In my former book, Theophilus, I wrote about all that Jesus began to do and
to teach 2until the day he was taken up to heaven, after giving
instructions through the Holy Spirit to the apostles he had chosen. 3After
his suffering, he showed himself to these men and gave many convincing
proofs that he was alive. He appeared to them over a period of forty days
