1966年1月8日至9日,台湾海峡。剑拔弩张对峙的国共双方之间爆发了一场不寻常的战
斗,从3个解放军中的败类叛变、杀害战友劫船逃往国民党控制的马祖岛开始,以这3名
叛徒和一批国民党达官要员们一同葬身鱼腹告终,前后仅短短的16个小时。这段传奇,
相信许多读者已经耳熟能详了。不过,今天我们将从海峡对岸的另外一个角度来解读这
段往事。
1966年1月8日深夜,福建前线驻霞浦守备第7师下辖的闽北船运队第2中队的4艘美制50
吨LCM型登陆艇,奉命从福州马尾港装运一批物资前往宁德地区霞浦县古镇。登陆艇编
队以10节左右的速度向东北方向行驶,行驶到接近台湾方面占据的马祖岛附近海域时,
为了防止遭到马祖国民党守军炮火的射击,编队依预订的航行计划实行了灯火管制、摸
黑航行。
位于艇队最后的是F131号登陆艇,该艇共有人员10名,分别是艇长甘九郎,信号班长魏
献美,船员陈振新、张正庆、许忠义、施林岳、杨保,以及领航员吴文献、轮机员吴珍
加及高射机枪射手吴春富。最后这三位吴姓战士都来自福建省... 阅读全帖

第一篇JACS文章的老板亲口说的是看了我们的一篇文章得到的idea,从我们的idea到这
个idea是再简单直接不过的想法。其实这个材料我差不多在两年前就做了,因为我知道
老板不发文章, 即便是nature也不会发, 所以最后的高分子就没有做。但相似的东西
自己还是做了一些,性能也不错。毕业的时候,我和师弟说这一系列你应该接着做,
结果他就做了这个材料, 但老板不让送出去做太阳能测试。
想想PhD, 同样的材料, 别人发了JACS和nature, 我就整了一篇Org. Lett, 而且我们
知道这个材料有人做,还是拖着不发。 最后因为要评tenure要文章, 才发了一片

比较罗索,谢谢大家。
Sec. I. Introduction
(1)
最近发现2010有很多nanowire/pore solar cell的文章发在nano lett/JACS。
比如
http://pubs.acs.org/doi/abs/10.1021/nl100161z (PDY)
http://pubs.acs.org/doi/abs/10.1021/ja910082y (北京)
文章中说转换效率都在10% 以下。textbook中说:
commercially mass-product cells are typically only 13-14% efficient.
另外,我看到有文章,就平板单晶硅放在液体电极里,效率都有10%
所以想问一下,上面2片top journal,也是用单晶硅,纳米制备成本很高,效率却很低,为啥可以发表?
(2)
别的nano 文章,号称可以用便宜材料,a-Si:H,
http://pubs.acs.org/doi/abs/10.1021/nl9034237 (Stanford)
但是纳米制备的成本难道比单晶硅材料便宜?
(3)
也有很多纯

你怎么知道不是造假, 实验条件不一样, 电镜结果却一模一样?!

投资者担心美国万一坠落「财政悬崖」,下周股市可能崩跌。其实更可怕的是,华府数周后不及时达成协议,提高国债上限,因为这可能导致联邦赖债、信评再次降低、金融市场恐慌。
国家广播公司报导说,市场策士表示,如坠落财政悬崖,导致加税和政府大肆削减开支,势必严重损害消费者和企业信心,不过美国经济还会再过一阵子才会陷于衰退。国会在这段期间有很多机会采取补救措施,扭转一些坠崖效应。
这是美国股市仍未显现崩盘迹象,只是逐渐下降和震盪加剧的原因,也使华府能够不予理会。以往股价一旦崩跌,国会都会被迫采取行动。
财政部长盖纳表示,美国技术上今年底就会达到国债上限。
白宫声明不打算对国债谈判,采取2011年的同样做法,不过它可能被迫重蹈覆辙,而这是市场最可怕的恶梦。
2011年的国债谈判,原来的程序之争引发激烈对抗,市场接连暴跌,连通过提高国债上限的法案之后,股市仍然狂泻,对华府的运作能力表现一种不信任投票,史坦普信评机构也破天荒的把美国债信降低一级。在当年8月21日为止的四周内,史坦普500指数暴降16%。

来自主题: History版 - 宋代状元的寿命
一、宋代状元的寿命
宋代共出状元118名。其中,已知其生卒年或虽不知其生卒年却知其寿数的共70人,
占总数的59.32%(保留两位小数,下同)。依据这70人的年龄资料所得出的若干统计
平均数,也许能接近实际情形。这70人中,80岁及80岁以上的5人,占7.14%:
黄裳(1044-1130),87岁(《全宋词简编》第202页)
郑性之(1172-1255),84岁(《中国历史大辞典·宋史卷》第301页);
阮登炳, 82岁([洪武]《苏州府志》卷三十五,总页1424页);
刘章(1100-1179),80岁(宋人传记资料索引》总第3872页);

说辽国40万宫帐军,120万京州兵并无夸大之说,是有依据的。辽国除了中京大定府缺
乏记载外,上京,东京,南京,西京四府就有了1097300的记载,中京以10万京州兵估
算,辽国拥有120万京州兵左右的实力,这些京州兵平是为民,一旦战争需要,即为120
万后备兵力。
辽国强大的武力,远非汉朝汉武帝时期的匈奴,唐朝唐太宗时期的突厥可以相比。
历史上匈奴最强盛的时候是在西迁到欧洲的匈奴王阿提拉的时候,那时候和汉朝的匈奴
相隔几百年了。汉武帝时期匈奴没有8万精锐骑兵部队,也没有24万后备部队,
历史上突厥最强盛的时候是隋朝时期,但是被隋朝打成分裂了,唐朝唐太宗时期突厥实
力大不如前,唐军进攻的时候,更是无法组织5万骑兵抵抗了。也没有24万后备部队。
更不要说辽国杰出的军事领袖耶律阿保机强过匈奴突厥那些单于,辽国中兴的辽景宗,
辽太后,他们的政治才能远强于当初那些匈奴,突厥单于。
辽国的将领,耶律休哥,耶律斜诊,耶律隆庆,萧达凛这些人的军事素质和指挥才能,
远强过那些匈奴将领和突厥将领。这些算的上辽国的名将。
尤其是耶律休哥和耶律隆庆的指挥才能,其中耶律隆庆999年瀛州血战的指挥艺术,还
