于敏是中國氫彈之父，中國工程院院士，國家最高科學技術獎獲得者。他隱姓埋名28年，為中國核武器發展做出不可磨滅的貢獻，被譽為"兩彈一星"元勛。他的一生詮釋了什么是真正的科學家精神——愛國、奉獻、求實、創新。

Yu Min is known as the father of China's hydrogen bomb, an academician of the Chinese Academy of Engineering, and a recipient of China's Top Science and Technology Award. He worked anonymously for 28 years, making indelible contributions to China's nuclear weapons development and is honored as a pioneer of China's "Two Bombs, One Satellite" program. His life exemplifies the true spirit of a scientist - patriotism, dedication, pragmatism, and innovation.

1926年，于敏出生于河北寧河一個普通家庭。幼年時正值戰亂年代，他親眼目睹了國家積貧積弱的狀況，這在他心中埋下了科學報國的種子。盡管家境貧寒，但父母堅持讓他接受教育，展現出非凡的學習天賦。

Born in 1926 into an ordinary family in Ninghe, Hebei, Yu Min witnessed China's poverty and weakness during the war-torn years of his childhood, planting the seed of serving the nation through science in his heart. Despite financial difficulties, his parents insisted on his education, where he demonstrated extraordinary academic talent.

1944年，于敏以優異成績考入北京大學物理系。當時中國物理學基礎薄弱，許多教材都是英文版，他克服語言障礙，常常通宵達旦地學習。1949年畢業后，他被錢三強選中進入中國科學院近代物理研究所，開始了他與核物理的不解之緣。

In 1944, Yu Min was admitted to the Physics Department of Peking University with outstanding grades. At that time, China's physics foundation was weak, and many textbooks were in English. Overcoming language barriers, he often studied through the night. After graduating in 1949, he was selected by Qian Sanqiang to join the Institute of Modern Physics at the Chinese Academy of Sciences, beginning his lifelong connection with nuclear physics.

1950年代初期，中國核物理研究幾乎從零開始。于敏和同事們面臨著設備簡陋、資料匱乏的困境。他回憶說："我們連最基本的實驗設備都沒有，只能靠理論計算和推導。"但正是這種艱苦環境磨礪出了他扎實的理論功底和創新能力。

In the early 1950s, China's nuclear physics research started almost from scratch. Yu Min and his colleagues faced difficulties with rudimentary equipment and scarce resources. He recalled: "We didn't even have the most basic experimental equipment and had to rely on theoretical calculations and derivations." Yet it was precisely these challenging circumstances that honed his solid theoretical foundation and innovative capabilities.

1961年，錢三強找到于敏，希望他轉向氫彈理論研究。這意味著放棄已有成就，進入一個全新領域。于敏毫不猶豫地接受了這個關乎國家命運的任務，從此隱姓埋名，開始了長達28年的秘密研究工作。他曾說："國家需要我，我一定全力以赴。"

In 1961, Qian Sanqiang approached Yu Min, hoping he would shift to hydrogen bomb theoretical research. This meant abandoning his existing achievements and entering a completely new field. Without hesitation, Yu Min accepted this mission crucial to the nation's destiny, beginning 28 years of anonymous secret research work. He once said: "If the country needs me, I will give my all."

1967年6月17日，中國第一顆氫彈爆炸成功，從原子彈到氫彈，中國僅用了2年8個月，創造了世界最快紀錄。這一成就背后是于敏提出的"于敏構型"，這一獨特設計使中國氫彈具有小型化優勢。晚年他仍堅持工作，培養了大批核物理人才，為中國科技發展繼續貢獻力量。

On June 17, 1967, China's first hydrogen bomb was successfully detonated. The transition from atomic to hydrogen bomb took China only 2 years and 8 months, setting a world record. Behind this achievement was Yu Min's proposed "Yu Min configuration," a unique design that gave China's hydrogen bomb a miniaturization advantage. In his later years, he continued working and trained numerous nuclear physics talents, continuing to contribute to China's scientific development.

于敏常說："一個人的名字，早晚是要沒有的。能把微薄的力量融進祖國的強盛之中，便足以自慰了。"他淡泊名利，將畢生精力奉獻給國家需要的事業。他的故事告訴我們：真正的偉大不在于個人榮耀，而在于為國家民族做出的貢獻；真正的成功不在于外在成就，而在于內心堅守的信念。

Yu Min often said: "A person's name will eventually fade. Being able to integrate one's modest strength into the prosperity of the motherland is comfort enough." He was indifferent to fame and fortune, devoting his life's energy to causes the nation needed. His story teaches us: true greatness lies not in personal glory but in contributions to the nation; real success is measured not by external achievements but by the convictions held in one's heart.
