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 |

- 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)。 |

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! |

我一直感觉Reuters 有日本的间谍,他们会通过报道来传递针对华人屠杀的计划,和发
布不利于华人的报道,制造舆论。最重要他们后边的势力和犯罪集团有关。有必要好好
调查这个组织。
How top U.S. colleges hooked up with controversial Chinese companies
By Steve Stecklow and Alexandra Harney
Filed Dec. 2, 2016, noon GMT
New Oriental, China’s biggest private educator, has been accused of
academic fraud. Thanks to two enterprising Americans, it has also gained
access to leading U.S. college admissions officers.

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。
接下来看文章,文章标题:

Al-Qaida spokesman Adam Gadahn a fan of 60 Minutes but said Fox News 'lacks
neutrality' and CBS is 'close to being unbiased'
Osama bin Laden pondered the merits of US television news channels as he
considered how to extract the best propaganda benefit from the tenth
anniversary of 9/11 last year, and concluded that CBS was "close to being
unbiased".
But an American-born media adviser for al-Qaeda warned Bin Laden to beware... 阅读全帖 |

Diametrically Opposite Claims Made by 2 AsAm Orgs.
On 6/26/2012, AALDEF, whose Exec. Director is Margaret Feng
(i**[email protected] ), issued a press release*. Its title is "The Majority of
Asian
Americans Support Race-Conscious Admissions Policies." Wow, what a claim!
AALDEF also claimed that 80-20's survey was flawed.
A few Months ago, 80-20 EF, whose President is S. B. Woo, did an open and
neutral survey. It found that for every 1 AsAm who chose to OPPOSE, 52 A... 阅读全帖 |
