鈾彈 的英文怎麼說
中文拼音 [yóudàn]
鈾彈
英文
uranium bomb-
Uranium holds not only the promise of a vast new energy source, but also the grim specter of an atomic bomb.
鈾不但能提供巨大的新能源，也能產生原子彈這種殘酷的惡魔。This combination of uranium and hydrogen is called a " hydrogen bomb "
這種鈾和氫的結合，叫做「氫彈」 。In analyzing the neutron active detection, the neutron multiplication in the nuclear warheads induced by outer neutron source with different neutron energys is studied with numeral simulation, and the feasibility of through counting neutrons to determine the presence of high enrichment uranium ( heu ) in nuclear warhead has been proved. the method of detecting the warhead which contains heu pit by counting the released neut rons whose energy is higher than that of source neutron is studied. the feasibility of this method has been studied
對幾種主動探測核彈頭方法進行的研究中，首先對不同能量各向同性外源中子照射核彈頭的中子增殖行為進行了數值模擬，檢驗了用外源中子照射核彈頭后，通過測量瞬發中子在核彈頭中的增殖量，來證明核彈頭中高濃鈾存在的可行性；研究了用能量低於1mev的外中子源照射核彈頭，用測量核彈頭中裂變產生的高於源中子能量中子數的方法探測核彈頭，通過數值模擬分析了可行性。This combination of uranium and hydrogen is called a "hydrogen bomb".
這種鈾和氫的結合，叫做「氫彈」。The results show that the method is better than the method of counting prompt neutrons in distinguishing real and fake nuclear warheads
數值模擬表明，這種方法比計數瞬發中子總數有較大的優點，可用來探測鈾為彈芯的核彈頭。The results show that coincidence detection method has obvious benefit in detecting nuclear warheads. for the same type warhead, the coincidence counts rates of the model of warhead of heu pit is 10 times as big as that of fake warhead of natural uranium pit. if we know the nuclear warheads configuration by other methods, the method of coincidence neutron detection could be used to distinguis h the fake nuclear warheads from the reals
計算表明用探測符合中子的方法探測核彈頭對區分真假核彈頭有明顯的優點，對于同一核彈頭模型，裂變彈芯是高濃鈾和用天然鈾替代高濃鈾時，符合中子計數相差1個量級，如通過其他途徑了解核彈頭的大致結構，符合測量的方法就可以有較高的置信度分辨真假核彈頭。Iran halted work toward a nuclear weapon under international scrutiny in 2003 and is unlikely to be able to produce enough enriched uranium for a bomb until 2010 to 2015, a u. s. intelligence report says
一份美國情治報告顯示，伊朗於2003年在國際細查后停止核武的研發，而且要到2010 ~ 2015年間才有能力生產足夠製造核彈的濃縮鈾。The "trigger" may be a conventional uranium-atom bomb.
這種「引爆器」可以是一枚常現鈾原子彈。If using the natural uranium to replace the heu pit in warhead, the delayed neutron counting rate would be about 3 times lower. the coincidence neutron detection is proposed to be used in nuclear warhead detection
計算表明用天然鈾替代高濃鈾作的假彈頭，它們的出殼緩發中子數相差約3倍，需在一定條件下，才可對真偽核彈頭做出判斷。Detecting nuclear warhead by counting delayed neutrons induced by neutron source is studied. the 2 - step calculation method is proposed to resolve the delayed neutron transportation issue. this method can save computer ' s calculation time, and is easy to operate
本文研究了用外中子源照射核彈頭，誘發其裂變材料裂變，探測緩發中子的方法，以此判斷高濃鈾與低濃鈾，從而為核查核彈頭的真偽提供依據。With the outer neutron source which can only induce 235u fission, it could possibly prove the presence of heu in a warhead by counting the coincidence neutrons. this method possibly provides one of necessary attributions in identifying the real nuclear warheads
本文研究了用中子符合探測方式測量能量低於1mev的外中子源在核彈頭中誘發的裂變數，以判別模型中是否含有高濃鈾，從而作為判斷核彈頭的真偽的可行性。Hazards of the depleted uranium shell and its protection

現在你裝備有高科技武器：元生質槍炮、鈾彈、中子炸彈等。Because of the upper limit of the nuclear density, which prevents the core to compress too far, the collapsing inner core will bounce back outwards. this out - going inner core will collide with the in - coming outer core, which is collapsing rapidly. this collision will send off shock waves and create heavy elements, like uranium
由於原子核的天然密度會成為巨大的阻力，防止核心進一步收縮，這時核心會猛烈反彈，以極高速塌縮的核心外殼會和反彈中的核心碰撞，產生強烈的沖擊波，同時產生出像鈾等比鐵更重的元素，並把恆星外殼炸毀，這便是分享友人
