标 题: 说说 丰田自动加速暴冲、如何处理以及买车
发信站: BBS 未名空间站 (Wed Feb 12 23:59:02 2014, 美东)
重提这个事情,目的是让更多普通丰田车主知道自己的车,万一碰到暴冲如何处理;另
一方面让新手和正在考虑买车的人也稍微增加一些了解,Make An Educated Choice。(
主要是闲的蛋疼)
写这个主要是给不太懂车的人看的,所以我的片面之词可能会误导别人,非常欢迎日黑
来喷;另一个出发点是,对于已经开着丰田的华人来说,知道的人越多越好。
第一危险性:
暴冲unintended acceleration很可怕,而且是随机的,可能在你趴车时出现,也可能
在你高速tailgate别人时出现。虽然丰田和别的专家已经(部分)复制暴冲,推断是软
件bug,但问题还没有充分解决。暴冲已经有多个致死的例子,具体真实数字日黑可能
会告诉您,您可以选择相信或者不相信。
第二如何处理:
暴冲是可以应付的,最重要的是要有思想准备,保持镇定。正确的处理... 阅读全帖

这两根hotwire哪根上,哪根下没分别。原理是这样的:
- 从电公司过来的是那两根hotwire(s)和电公司的电传输“地”(neutral wire)。
- 每根hotwire相对neutral wire是120V,但这两根hotwire的电又相位相反。你可以想
像成一根+120V,另一根-120V。
- 需要120V的时候,你需要一根hotwire(任何一根都行)加一根neutral。
- 需要240V的时候,你需要两根hotwire,不需要neutral。
- 需要240V+120V的时候(比如家里的烘干机),你需要所有两根hotwire,外加一根
neutral。
当然,那根bare/green wire是住家这边的接地线(每家都有一根很粗的铁棍似的线钉
入地里,比如俺家的在电表附近的墙边),总是需要的。这根“地”在主panel上是和
“neutral"接在一起的(sub-panel 上不是接在一起的)。

them may claim to be, or want to be). But in general, they are expected to
have a low beta, or low market exposure.
Even some so-called "market-neutral hedge fund index" has significant market

你这也是半瓶子醋。Neutral跟地线不是一回事,两条线要分开走,但并不是“neutral
线是不接地”,neutral线在供电端和入户的panel那里都是和地线接在一起的。
Neutral线和地线的作用不同,简单地讲平时正常通电使用中neutral线上是有电流的,
地线上没有电流的。

发信站: BBS 未名空间站 (Sat Dec 7 23:35:21 2013, 美东)
先定义一下clear吧,就是用两根手指去推shifter从neutral到1st,推到大概三分之一
的地方,shifter就会被1st吸过去的感觉,非常的清晰(clear)流畅(smooth)。
那么不clear不smooth的情况可以定义为(根据我亲身体验),用两根手指推,推到三
分之一的地方,就推不动了,好像有个什么东西挡住了一样,这时候必须要上手掌用力
往前推一下,才能进入1st。
再换一种表达,clear就好比穿鞋的时候,一蹬就进去了;unclear的时候就好比鞋里面
有个小气球(或者乒乓球,鸡蛋),轻轻蹬的话,是穿不进去的,要使劲蹬一下,把气

刚才电脑突然断电关机,然后发现是这间房间的所有的wall power outlet都断电了,
边上的房间也受到影响, 其它房间没有问题。到车库检测了那里的配电盒,breaker
都没有off. 下面是我的trouble-shooting:
1. 定位了出问题的线路的breaker并关掉(off), disconnect了hot线,换了另外一路hot线接过去,把breaker重置于on, 发现这个线路的插座没有问题; 同时把受影响的那个hot线换到别的breaker, 插座仍然没用电。我想可以以此排除这个breaker的问题。
不知从breaker出来的电线到wall outlet之间, 应该怎样trouble shooting. TIA!
这个房间的所有outlet都不是gfci的。 bathroom有一个gfci的插座, 可是当时也没用人在用啊。

I'd like to stress the following points:
1. "Risk neutral" and "Risk free" are two different concepts
2. Risk neutral probabilities exist if and only if there is no
arbitrage.
3. The risk neutral probabilities are unique if and only if
the market is complete.
4. Under risk neutral measure, or say in the risk neutral world,
investors are indifferent to risk, requesting no additional
compensation for risk(risk premium), therefore, CFs are discounted at
risk free rate.

来自主题: Quant版 - 关于Delta Hedging的疑问
你delta neutral只相对于当时一小段时间neutral。underlyer价格一变就不neutral了
,更不用说一路到expiry。另外option都有theta,underlyer价不变你都会有pnl。所以delta
neutral的portfolio需要隔一段时间adjust。你要想安心一点就搞gamma hedge,这样delta的
delta也是neutral的。但仍然要定时adjust。

来自主题: _Auto_Fans版 - V6 mustang 换挡有时很不clear
先定义一下clear吧,就是用两根手指去推shifter从neutral到1st,推到大概三分之一
的地方,shifter就会被1st吸过去的感觉,非常的清晰(clear)流畅(smooth)。
那么不clear不smooth的情况可以定义为(根据我亲身体验),用两根手指推,推到三
分之一的地方,就推不动了,好像有个什么东西挡住了一样,这时候必须要上手掌用力
往前推一下,才能进入1st。
再换一种表达,clear就好比穿鞋的时候,一蹬就进去了;unclear的时候就好比鞋里面
有个小气球(或者乒乓球,鸡蛋),轻轻蹬的话,是穿不进去的,要使劲蹬一下,把气
球踩爆了,才能穿进去的感觉。
好了,定义完了来说我的经历,7个档位里面,有时候会发生这种unclear的情况,目前
看来1档,2档和倒车档发生的概率非常高,10次里面可能有4-5次会unclear,剩下几次
是完全clear的。其他档位偶尔会有,但是不如1,2和R频繁。
还有一点要说明的是,如果我在熄火状态下,踩着离合反复从neutral到1st,再到
neutral再到1st,第一次是unclear,后面就全部都是clear了,然后1... 阅读全帖

Neutral和grounding不是一个概念,我很清楚。我可以明确肯定地告诉你,单相变压器
不是只有你说的那一种接法,我亲自做过120/240输出的配电AC,得到240,不必一定
120/-120叠加,完全可以独立火线对地线。
Neutral不接地是你扯淡了,neutral只接地一次,基本在输出端就接了,就是说你不能
一用到Neutral就接地一次,所以体现在用户端不必再接地。

裤裆里放屁,正确(“震雀”)!
看一看英文的NEC CODE,上面写得很清楚:one phase....
所以美、加民用的是单相电240V,120v/240v是抽头分出来的。
另外,Neutral和grounding千万不要胡来,原理是这样的:
正常情况下,Neutral是回流电流,地线是不带电的。当漏电发生时,如机壳带电,如
果人正好去摸机壳,则此时,电流有三个回流路径,
1 Neutral 2 地线 3 从机壳-〉人-〉地
由于地线路径电阻最小,所以大部分回流电流(A很大)可以通过地线瞬间回流至
breaker,从而使其在最短的时间短开,以达到保护人的目的。
接地和Neutral不要混用,请珍惜生命!

国内论坛上的千老有发帖子,看上去像回事儿,版上的内行可以鉴定一下(以下转载):
昨晚收到的消息,中科院石正丽教授组发现武汉冠状病毒最高同源度蝙蝠亲本株,算是
重大突破,特此刊文。
中科院石正丽教授是从事国内蝙蝠冠状病毒长期研究工作的科学家,其在蝙蝠冠状病毒
领域发文权威性目前业内最高,早前SARS病毒亲本蝙蝠株溯源也是由该组最早完成的。
这次获得的蝙蝠亲本株同源性极高,DNA相似度达到96%以上,可以基本确认这次武汉冠
状病毒来源于中华果蝠,样本分离于云南,具体传播路径,宿主来源有待进一步研究,
需要对传播链条上周边所有蝙蝠及相关动物进行采样,建构完成传播链。
蛇作为中间宿主的研究因为北大组研究方法有问题,导师下了任务,我这边在重复北大
组的实验结果,扩大研究样本,近日会发布,北大组结果可能会被推翻。
