反引力手册摘录
By D. Hatcher Childress
Many researchers into the UFO enigma tend to overlook a very important fact.
While it assumed that most
flying saucers are of alien, or perhaps Governmental Military origin,
another possible origin of UFOs is ancient
India and Atlantis.
许多研究员进入不明飞行物谜之内容易看出一个很重要的事实。虽然多数被假定是外星
人的飞碟，或也许
是政府的军事来源，不明飞行物的另外一个可能的来源是古印度和亚特兰提斯岛。

summer and returned before the snow came back.

How often does a 100-year flood occur?
Large floods are often given designations as a "one-hundred-year flood" but
a 100-year flood does not mean that such a flood occurs once every 100 years
; instead it means that there is a one in one-hundred (or 1%) chance of such
a flood occurring in a given year.
Two 100-year floods could occur a year apart or even a month apart -- it all
depends on how much rain is falling or how quickly the snow melts. A "20-

发帖数: 30882 | 16 美国的独特性﹑文化政治与美国人的中国观
《凤凰周刊》副主编 玛雅
说起世界上其它国家﹐我们第一个想到的可能是美国。美国梦﹑美国精神﹑美国价值观
﹑美国模式……是我们很多人熟悉的字眼。而美国对内自由民主﹑公正平等﹐对外穷兵
黩武﹑实行霸权﹔对中国今天巧言令色﹐声称“战略伙伴”﹐明天又挥舞拳头﹐大叫“
中国威胁”﹐又让我们看到它的多面性。是什么造就了今天的美国﹐一个“美丽的”帝
国主义国家﹖我以为﹐认识美国﹐首先要了解美国的独特性（the uniqueness of the
United States）以及由此而生的文化政治。
美国人的基本价值观
美国不同于世界绝大多数国家的一个突出特点是﹐它是一个具有种族多样性（ethnic
diversity）的移民国家。除了本土的印第安人﹐所有的美国人都来自世界其它国家 —
欧洲国家﹑非洲国家﹑亚洲国家﹑拉美国家。这么多不同种族﹑不同肤色的人信仰什
么﹖有什么样的主流价值观﹖什么样的行为方式﹖什么原因造成了他们的价值观和行为
方式﹖答案就在美国的独特性。
美国的种族多样性是从17世纪开始逐渐形成的。从17世纪到1776年宣布独立﹐美国的移

The loss of Arctic sea ice helps accelerate the warming of the atmosphere in
the far north, thanks to what's known as the albedo effect. White ice
reflects sunlight into space, cooling the air, but when ice melts and is
replaced with dark ocean water, the effect is reversed and more of the sun's
heat is absorbed. As the Arctic air warms, it raises the altitude of
discrete areas of high pressure, which can then alter wind patterns. Th... 阅读全帖 |

另外，核电站用的不是武器级铀，只会melt down，不会像原子弹那么高效爆炸
影响范围一般不超过10km，就算日本全部核电站爆炸，也不会被炸平。
但是核电站爆炸以后的辐射云就很难办，这个对全球都有影响。

核材料棒.
核材料棒会发生裂变反应,一个大的原子核被中子激发后会分裂成
几个小的原子核,同时放出更多中子.更多的中子又会打到更多的大原子核上面,
导致其分裂,这样不断下去就是链式反应. 同时核分裂会放出大量的热.
正常工作时候,用水流到反应炉里面,把产生的热量用来发电.
地震的时候应该是紧急关机了,怎么关机呢?就是把控制棒插到反应棒里面去,
把裂变产生的中子吸走,链式反应就不会继续.

发帖数: 25423 | 24 到目前为止正式消息都是控制棒没有问题，现在的热量是残余放射性材料衰变
产生的，如果是控制棒的问题，根本撑不到今天，冷却失效的话几分钟之内
燃料棒大概就熔了。
这个冷却系统很奇怪，都出同样问题了。赶紧灌海水吧。 |

发帖数: 9629 | 25 所以一定要控制燃料棒不能因为高温而融化.
融化以后呢,会掉到下面的一个大海水池里,
这时候控制棒不起作用了,核燃料融化成了一大滩,核反应速率天知道,
大概会越来越热,越来越热,最后往地下一直掉.
所以呢,首要问题是把燃料棒的温度降下来,
之前史那海水进去灌.新的消息说已经不顶了,在灌硼酸.
把整个反应炉灌满硼酸.
硼酸是很好的中子吸收剂,相当于更大更强的控制棒.
把所有核裂变产生的中子都吸收掉,
链式反应就不会继续,温度也就不会升高.
我觉得灌了硼酸应该是没问题的. |

发帖数: 556 | 28 斗胆补充两点：
1）燃料棒烧了一段时间之后的确是中空的，中心都是fission gas，含有很多裂变产物
。不过新的燃料棒的确是实心的。不过这因该对中子的空间分布影响不大，反倒是有核
燃料的地方种子更密集，因为链式反应，就像您说的。其实只要控制棒能够把中子增值
速度降到临街条件以下，链式反应应该马上就会停止，因为种子在反应堆中的平均自由
程很短，种子分型速度又很快。余热因该大部分是因为还没有来得及衰变的裂变产物继
续衰变时产生的。
2）Meltdown之后，堆芯由燃料-水-燃料这种heterogeneous结构变成燃料和水混杂在一
起的homogeneous结构，根据我的记忆，一般反应堆里homogeneous的材料结构更不利于
链式反应，这也是为什么把堆芯设计成这种燃料和水交替存在的结构的原因之一（更容
易达到临界）。所以meltdown之后反应性是否会增强也有待考察。
我觉得meltdown对堆芯是毁灭性打击毫无一问，但是对外界环境的影响并没有这个词本
身那么可怕。 |
