1945年7月,在美国新墨西哥州的阿拉莫哥多城外,科学家们异常紧张,因为他们几年来秘密工作的赌注将押在一系列可能失控的反应上。重达2.3吨的TNT炸药,将作为引药去点燃仅重6千克的钚合金。7月16 日凌晨5点30分,第一颗原子弹在美国西部沙漠试爆成功,释放出相当于1.9万吨TNT炸药的能量。没有时间进行第二次核试验了。第二颗原子弹去用于改变历史的进程。
In July 1945, outside of Alamogordo, New Mexico, the United States, scientists were extremely nervous because their bets for secret work over the years would be held in a series of potentially out-of-control reactions. TNT explosives weighing 2.3 tons will be used as primers to ignite neodymium alloys weighing only 6 kg. At 5:30 in the morning of July 16, the first atomic bomb exploded successfully in the western desert of the United States, releasing the equivalent of 19,000 tons of TNT explosive energy. There is no time for a second nuclear test. The second atomic bomb was used to change the course of history.
