“596”是我国第一颗原子弹的代号,它是1959年6月苏联来信拒绝向中国提供原子弹教学模型和图纸资料的日期。从1959年下半年开始,我党中央决定完全按照独立自主、自力更生的方针发展核武器,到今年已整整30年了。在建国40周年之际,回顾我们走过的路程,从中得到一些有益的启示,对激励我们继续奋斗,争取更大的成就是很有必要的。 “596” is the codename of China’s first atomic bomb. It is the date that the Soviet Union’s letter in June 1959 refused to provide China with atomic bomb teaching models and drawings. From the second half of 1959, our Party Central Committee has decided to develop nuclear weapons completely in accordance with the principle of independence and self-reliance. It has been 30 years since this year. On the occasion of the 40th anniversary of the founding of the People’s Republic of China, it is necessary to review the journey we have traveled and get some helpful enlightenments from them to encourage us to continue our struggle and strive for greater achievements.
