原子弹背后的故事 历史上的今天 10月16日

  On October 26, 1964 are all descendants of exciting day, for our country the first atomic bomb explosion success. Is our senior scientists from their hands, and wisdom, and to defend the motherland's powers. Defend the nation's security, and from this day we started by nuclear threat is. But in power. Also, we have today can sit in the classroom quietly reading.
  一九六四年十月十六日,这是一个让所有炎黄子孙为之振奋的日子,我国第一颗原子弹爆炸成功。是我们的前辈科学家用他们的智慧和双手摆脱列强,捍卫着祖国的尊严。保卫着国家的安全,从这一天开始我们不在受到核武器的威胁。而立于强国之林。也才有我们今天能够坐在教室里安静的读书。

  今天为大家讲述的是原子弹背后的故事。大家都知道原子弹是由邓稼先,钱三强等科学家研究出来的,那大家知道原子弹的原料是怎么来的吗?在现在看来是有些可笑,可是我却被深深的震撼了。它们是由现在大家都看不起的农民一点一滴,用人类最原始和简陋的材料,在山寨工厂里,流血流汗,不顾放射性危险,硬凑出来的。
  二机部的袁成隆副部长说,土法炼铀,老百姓搞,我听说云南云沧那个地方有农民在那儿炼铀,就亲自去看看到底怎么样。去了一看,到处是小高炉,正在那儿炼呢,一个副专员在那儿主持这个事儿。开采呢,就是用镐刨,那个矿比较富,把那含铀矿刨出来。要碾碎怎么办呢,没有别的办法,用碾子,就是老百姓碾粮食的那种碾子(日后还要用那个碾子压粮食),把那铀矿石碾碎。碾碎以后得过滤啊,那就用做豆腐的麻布包过滤,一道一道过滤。最后得出细一点儿的,那个铀的沫,这也叫初铀。将来拿这个就可以搞氧化铀、四氟化铀、六氟化铀,一道一道弄下去了。
  土法炼铀获得土法冶炼的重铀酸铵163吨,为原子弹试验的核燃料的生产提供了原料,进而为中国第一颗原子弹的研制赢得了时间。对此,美国学者刘易斯和薛理泰说,从一定意义上讲,中国的第一颗原子弹是一枚人民炸弹。
  先辈们为了捍卫祖国的尊严,连命都不要了,在建造原子弹的这座丰碑上不仅有邓稼先、钱三强等伟人的身影,碑下还浸润着农民的血汗。
