The transmission factor describes the gradual opening of a fission channel as the energy approaches the fission barrier. 透射因子描述了當能量趨近於裂變勢壘時裂變逐漸地開放。
On the average, in weapons of this type, roughly equal amounts of explosive energy result from fission and from fusion. 平均說來，在這類武器中，由裂變和由驟變所產生的爆炸能量大致相等。
Nuclear fission releases tremendous amounts of energy. 核裂變釋放出巨大的能量。
One of the methods to set free the energy locked in such substances as uranium is known as nuclear fission. 一種把儲存在象鈾這樣的物質裡面的能量釋放出來的方法被稱為核裂變。
