身为全球头号强权美国的新世代主力水面舰艇,本级舰从舰体设计、电机动力、指管通
情、网路通信、侦测导航、武器系统等,里里外外无一不不是超越当代、全新研发的顶
尖科技结晶,所以美国海军除了采用螺旋推进的开发策略外,并将DD(X)的各种主要
技术难关列为十大关键技术,并分别指定承包商针对这十大技术通过工程发展模型(
Engineer Development Model,EDM)的方式进行实际的测试。
这十大关键技术包括:
穿浪逆船舷舰体(Wave Piercing Tumble Home)
MK-57垂直发射系统(舰体周边垂直发射系统,Peripheral Vertical Lauhcn
System,PVLS)
整合复合材料舰岛与孔径(Integrated Composite Deekhouse and Apertures,
IHDA)
红外线模型(IR Mockups)
整合式电力推进(Integrated Power System,IPS)
双波段雷达(Dual Band Radar,DBR)
整合水下作战系统(Inte... 阅读全帖 |

How it works:
U.S. banks and credit unions report incidents to ChexSystems to protect
themselves and other banks in the future. You get reported to ChexSystem
s if your account is closed for "cause." What is "for cause?" Banks diff
er greatly between them as to what valid reasons are for closing an acco
unt. Here are some examples:
The bank was unable to collect for an overdraft, ATM transaction, or aut
omatic payment which they honored on insufficient funds.(Re |

OMAT简直能恶心死人,无比仇视丑化中国。 |

ecting them to a PC, short of leaving them alone for ~5 minutes (they'll aut
omatically turn off), or taking out the battery pack.
I don't think there is a way. I just pop the battery pack off and back on qu
ick to kill the power to the controller, myself.
搜出来两个论坛的讨论结果..
哈哈,看来你错了....
答案是:没有.. |

L**y 发帖数: 128 | 5 最近跟roomate经济都比较紧张,严重缩减了外出吃饭购物的次数,今天实在觉得闷,于
是决定去看场电影。Carmike的电影平时都1块钱,到了周末就要3块钱,roomate开玩笑说
,哇,一模一样的电影平白被多收两块钱,实在划不来啊,于是我就豪情万丈的说,没关
系,姐姐我请你。。。。。。。。。。。。。。。反正也就3块钱(小声地;P)结果把ro
omate逗的大笑不止。
后来我们就在雨夹雪的天气下,开车去了差不多5个迈以外的carmike。别看今天天气恶劣
,廉价电影院里的人还很多呢,大家都高高兴兴的,买吃的买喝的,我们当然也不能示弱
,就算电影院里的popcorn和可乐都贵,而且我们从前也都没有看电影时吃吃喝喝的习惯
,不过为了随大流,我们还是高高兴兴地买了一小包popcorn和一小杯可乐。进了放映厅
看到人家都拿大盒大杯的,我们就互相鼓励说,没关系,虽然现在人家的popcorn是大包
的我们却只能afford小包的,人家每人一杯可乐我们只能两人share一杯,但以后,等咱
有了钱,要看电影可以包下整个放映厅,躺着看。:)))
于是就看电影乐。电影是部好电影,温馨,动人,又幽默,看完后 |

这个例子清楚看到0-60的优秀成绩对于家用车来说意义真的很小。综合成绩和整体设计
的合理性更重要。
