爆了两个料: 猛踩油门时震动大。A4 6.x加速是用应试办法作出来的,街上实战情况下
更接近7.x秒。
用T没错,那句老话there is no replacement for displacement也没错,但2.0T买3.0
~3.5的钱还是不厚道。

Our skepticism centers on the engine bay, where Audi once again sends its
turbocharged four-cylinder power plant up against the six-cylinder
competition. While the revised 2.0T gets the job done at the test track, it
sounds like a Civic, and the steering wheel vibrates with four-cylinder
fervor at full throttle. We sus... 阅读全帖

发信站: BBS 未名空间站 (Wed Apr 25 10:59:54 2012, 美东)
Volkswagen boss Martin Winterkorn is pushing hard to reach his target of
surpassing Toyota and making VW the world’s No. 1 car brand by 2018. To
accomplish that goal, Winterkorn is bringing the next-generation Golf to
market in 2013, a year or two earlier than planned. But that’s not the only

丰田2013年6月6日公开了预计将于年内作为2014年款投放市场的新一代“卡罗拉”(北
美版)的概要,价格及详细性能指标将在临近上市时发布。
这是第11代卡罗拉,为了吸引更年轻的用户而非维持以往用户,继“Avalon”
及“RAV4”之后,丰田再次采用了个性强烈的外观设计。前脸以较扁的前大灯以及下部
带大开口的保险杠等为特点,并搭配大幅膨出的翼子板以及向后平缓下滑的C柱。
新款卡罗拉的外形尺寸为长4639×宽1776×高1455mm,与上代车型相比车长增
加99mm,车宽扩大16mm,但车高降低10mm。轴距为2700mm,比上代车型长100mm。由于
轴距更长,因此后座臀点后移了75mm,另外还通过减薄前座靠背,使后座乘坐空间变得
宽敞。

qqzj (小车车) 于 (Sun Nov 10 10:07:57 2013, 美东) 提到:
1理论
基本论点:升马力是评价发动机表现(performance)的唯一依据,而不是BMEP。这里的
performance仅指马力大跑得快。升马力的意义很明显。这里集中讨论为什么BMEP不是
正确的标准。因为BMEP和升扭矩是线性的,所以为了大多数人容易理解,这里在BMEP和
升扭矩之间画等号。因为升马力 = rpm*升扭矩,升扭矩作为衡量标准的缺陷非常明显
,因为这个指标仅仅描述了发动机在每一个完整冲程内做功的多少或者平均扭力的大小
,完全无视发动机在一定时间内可以运行多少个冲程。事实上升扭矩是随着rpm变化的
。所以升马力 = rmp * 升扭矩(rpm,x)。升扭矩(rpm,x)意思是升扭矩是rpm和其他因
素的函数。这个公式直接表明,如果升扭矩在一定rpm的区间下降,但是只要下降的速
度小于1,为了提高升马力,可以牺牲升扭矩。简单来说比较升扭矩的意义只有在相同
rpm的情况下在有比较的意义。当... 阅读全帖

Considering that the diminutive Abarth comes with a roly-poly driving

2. 车顶强度静态测试
一说翻车,大多数人会想到车顶着地的场景,于是本能地认为车顶强度与翻车时车辆的
安全性能有很大关联,有一部分研究者实际上也是这样想的。总结一下,正如NHTSA假
设的三点(图1):一是车顶强度(SWR值大小)与翻车时乘员伤势程度有关,二是翻车
时车顶形变与翻车时乘员伤势程度有关,三是车顶强度(SWR值大小)与翻车时车顶形
变有关。可以看出,在这个关系中,SWR是“因”。所以基于以上假设,就有了车顶强
度静态测试这种间接的评价方式。在这类测试中,最知名的应该是IIHS的roof
strength test。除此之外,NHTSA也做过类似的测试研究。
这种静态测试,主要考查的是材料本身的力学性能,跟那种材料拉伸压缩实验有相似性
。从这个角度来看,车顶强度静态测试曲线跟塑性材料应力-应变曲线也有对应的相似
性。举个例子,图2是2012 Mercedes-Benz ML 350的IIHS roof strength曲线,图3则

GM Takes On Ferrari and Lamborghini With the 2019 Corvette ZR1
With a 755-horsepower V8 engine that can reach 210 miles per hour, it’ll
offer those stallions some serious competition.

It’s also the most powerful street car General Motors has ever produced.
The six-figure coupe comes with a 755-horsepower V8 engine and a top speed
of 210mph. That’s more powerful than even Ferrari’s $320,000 F12 and

目前我知道的系里有一个老教师完全这样做了。我觉得事前录video还是很花时间的,
不过好处是麻烦一次(如果能录满意的话),今后再教就容易了?
Faculty typically spend a lot of time teaching—over 20 hours of a 50-hour
workweek in one study (Bentley and Kyvik 2012). Are we spending that time
productively? Obviously, whether or not we feel productive depends on what
we hope to accomplish as instructors. For example, virtually all the faculty

认真的回答你说,对于这种工作,就算不收钱也算是emplyment。这个有两个非常容易
搞错的概念,就是免费工作和自愿者的区别。
对于真正的volunteering, 那个工作必须本来就是不需要给钱的,而且他们对你的
performance 必须没有期望值。但是,如果你去社区学校去教书,那么首先就打破了这
两个条件了。因为社区学校教书的普通工作按理是应该给钱的,只不过有些老美为了换
取经验而同意为他们免费工作。所以这个事情的性质,不管你和那个学校如何看待以及
你愿意如何称呼你的工作性质,在劳工部的角度看来,这个就是一个“工作”。虽然你
自己出于某些原因自愿不领薪水,但是这个仍然是一个“工作”。所以对于J-1 VISA
也是必须事先获得雇主同意的。
相关的条款这个学校的办公室说得很清楚:

Work that is unpaid may still be considered employment for F-1 or J-1
status holders.... 阅读全帖

no doubt you are single child?
i just don't understand why you displace all the hatred to his parents when
who HIT you was him, not his parents!
This is so silly. And not fair.
It's OK to admit that you look down upon them. If you so obviously do it, it
's really better to just admit it than deny it.
