发帖数: 1651 | 6 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。

发帖数: 300 | 10 或许上面的解释确实造成了误解，怪我口齿不清了。清楚点说就有点复杂，因为不得不
提dynamic range。
hiss小本身不一定是高信噪比，因为还要考虑dynamic range，大震膜话筒普遍的优势
。dynamic range的扩展是向上（大声压）向下（小升压）两个方向的，大震膜更多在
向下方面的优势。大声压的话小震膜更容易做，比如录鼓的那些专用话筒。信噪比和
dynamic range相关，但没法说哪个决定哪个，是互相决定。提到录入小信号，就只关
心灵敏度，是最容易被理解的，但从这方面改进的技术含量和难度比从dynamic range
入手要低得多。就像你后面帖子说的，振膜薄一点轻一点就有效果。对于好的大震膜话
筒，靠高信噪比可以把很小的会淹没在低信噪比话筒里面的环境噪音和自身hiss分开。
所以我上面写“同level的电路背景噪音”的时候，它会更受环境噪音的影响。 |

新的receiver用了几个星期，感觉差别还是挺大的。现在用的是Klipsch RF-82 II的前
置，RC-62的中置，R-12SW的低音。30%电影，70%音乐。
功率上，V577 标称的115W per channel（1 channel driven）和 80w per channel
（2 channels driven）完全是虚高。虽然Klipsch的这几个音箱都是98db的，v577也就
能推个5-6成。当然能推几成和音量大小关系不大，主要是动态。随便一个电影就能听
出很大区别。当年买RF-82 II 的时候啥也不懂完全是被忽悠了，sales说Klipsch的音

我理解DYNAMIC TURN同义于DOWN-UNWEIGHTED TURN，在很多刻滑的教学里又叫CROSS-
UNDER TURN。特点是在换刃的时候不是起身减压，而是收腿蜷身减压(PULL-IN AND
ABSORB PRESSURE)，换刃后再蹬腿对板子加压(PUSH AND EXTEND)，形成这样的周期。
下面这个韩国教练RICKY的视频5：20后就是在示范DYNAMIC TURN，比SNOWPROFESSOR示
范的动作更夸张一些，但原理是一样的。
https://www.youtube.com/watch?v=JInbnK6XTlA
DYNAMIC TURN因为不用起身换刃，重心一直压低不会有大起伏，所以特别适合滑不整地
形。视频里和DYNAMIC CARVE相对应BASIC CARVE，重心起伏就大得多。
从技术原理来说DYNAMIC/DOWN-UNWEIGHTING可以结合大中小任何TURN SHAPE，就像

轮胎brake, 雨雪天反而会造成轮胎失去traction. DTC则允许轮胎有一定的打滑来保持
整体的traction
下面官网的解释
“When the drive wheels start losing traction the DSC automatically begins
stabilisation measures. The Dynamic Stability Control system curbs the
engine output and stops slip on the wheels. In exceptional situations,
however, a small amount of wheel slip can be an advantage.
When driving in deep snow, slush or on loose terrain a small amount of wheel
spin improves traction. For th... 阅读全帖 |

发信站: BBS 未名空间站 (Thu Dec 26 12:31:48 2013, 美东)
快新年之际给本版来点正能量吧。
刚收到朋友forward的邮件，他家（拜耳）regulatory affairs部门暑期在新泽西跟北
京貌似同时要招实习生，新泽西大概招4名，北京大概招3名。Application deadline是
一月底。北京的office要求是中国公民。貌似接受无经验(但最好略懂）的申请者。博
士优先。据朋友说往年最后录取者貌似中国人不少。实习的薪水方面，美国的薪水大概
在33-36刀每小时。有机会（但据说很不容易）在实习后拿到全职offer（朋友没拿到但
同批有人拿到）,base在80000-95000刀之间，年底双薪。所以第一年大概package在
95000到110000之间。起... 阅读全帖 |
