Based on varying process of generator terminal parameters after excitation fault, shortages of excitation protective principle of static stability boundary and asynchronous impedance boundary are analyzed. It proposed that excitation fault research relates to large-disturbance stability. Because dynamic power-angle character of generator after excitation fault is non-sinusoidal, there are differences between dynamic power-angle character and static state power-angle character. So it isn't ideal to protective operation result based on small-disturbance stability and static stability boundary criterion. At the same time, it proposed that asynchronous boundary impedance criterion is a constant reactive power circle moving adown j Xd′. It can ensure complete loss-of-excitation generator measuring impedance enter into the circle, but can't ensure the other condition measuring impedance including impossible losing synchronism enter. So loss-of-excitation protection would be maloperation when system voltage drops short and recovers or generator rejects load.③Based on stability principle, it puts forward setting conditions and calculation method of generator loss-of-excitation protection by direct measuring power-angle.

以励磁故障后发电机端的相关参数的变化为基础，通过对以静稳定边界和异步阻抗边界作判据的两类三种现行励磁保护在原理上存在的缺陷分析，发现：励磁故障是一个大干扰稳定性问题，励磁故障后的发电机的动态功角特性与静态功角特性有很大的差异，已远非正弦曲线，因此基于小干扰稳定性原理、以静稳定边界作判据的保护必然动作不理想；异步边界阻抗判据是一个下移j Xd′的等无功阻抗圆，它可以保证完全失磁后的发电机测量阻抗能进入该阻抗圆，但不能保证完全失磁之外的其它状态不会进入该阻抗圆，因此在系统电压短时下降或发电机突然甩负荷等情况下可能启动该保护使之误动。

Pumpkins are also a symbol of Halloween46; The pumpkin is an orange-colored squash, and orange has become the other traditional Halloween color46; Carving pumpkins into jack- o'-lanterns is a Halloween custom also dating back to Ireland46; A legend grew up about a man named Jack who was so stingy that he was not allowed into heaven when he died, because he was a miser46; He couldn't enter hell either because he had played jokes on the devil46; As a result, Jack had to walk on the earth with his lantern until Judgement Day46; So Jack and his lantern became the symbol of a lost or damned soul46; To scare these souls away on Halloween, the Irish people carved scary faces out of turnips, beets or potatoes representing "Jack of the Lantern," or Jack-o-lantern46; When the Irish brought their customs to the United States, they carved faces on pumpkins because in the autumn they were more plentiful than turnips46; Today jack-o-lanterns in the windows of a house on Halloween night let costumed children know that there are goodies waiting if they knock and say "Trick or Treat!"

南瓜也是万圣节的标志性象征。南瓜是橘黄色的，所以橘黄色也成了传统的万圣节颜色。用南瓜雕制南瓜灯也是一个万圣节传统，其历史也可追溯到爱尔兰。传说有一个名叫杰克的人非常吝啬，因而死后不能进入天堂，而且因为他取笑魔鬼也不能进入地狱，所以，他只能提着灯笼四处游荡，直到审判日那天。于是，杰克和南瓜灯便成了被诅咒的游魂的象征。人们为了在万圣节前夜吓走这些游魂，便用芜菁、甜菜或马铃薯雕刻成可怕的面孔来代表提着灯笼的杰克，这就是南瓜灯（Jack-o'-lantern）的由来。爱尔兰人迁到美国后，便开始用南瓜来进行雕刻，因为在美国秋天的时候南瓜比芜菁更充足。现在，如果在万圣节的晚上人们在窗户上挂上南瓜灯就表明那些穿着万圣节服装的人可以来敲门捣鬼要糖果。

The paleochannel-Ⅱ might form during the Holocene Optimal period.

古河道-Ⅴ形成于风沙-Ⅱ和Ⅲ期形成之前，可能是末次冰期之前，即中更新世或更早，这时河流能够进入古松辽大湖；古河道-Ⅳ形成于风沙-Ⅱ和Ⅲ期形成之时，可能是末次冰期时期，这时河流与松辽大湖萎缩，规模减小，河流已不能进入松辽大湖，而是消失在沙地之中；古河道-Ⅲ形成于风沙-Ⅱ和Ⅲ期形成之后，可能是末次冰期末期的冰消期，这时气温升高，大量的冰雪融水进入河流，促使河水漫流，流入沙垅垅间洼地，开始造成古西拉木伦河、古老哈河与教来河水文网之间的相互联系；古河道-Ⅱ形成于全新世适宜期时期，统一的西辽河形成，伴随气候变化，出现多次风沙进退，对应于风沙-Ⅰ期；河道-Ⅰ是现在，同属于风沙-Ⅰ期，活动沙地集中在翁牛特等地。

When the metal rods of cadmium were pushed all the way in, and stray neutrons that entered the pile were absorbed, and could not enter uranium—235 nuclei, and so there was no reaction at all.

当镉金属棒全部推入，进入反应堆的流动中子就被吸收，不能进入铀－－235原子核，因而完全没有反应。
