uranium fission 鈾核裂變。

uranium product

The simulation can be divided into three processes sequentially : calculating the induced fission neutron rate of uranium and space distribution by mam - li neutron source , computing the total uranium fission neutron count rate and time distributions of 42 3he tubes , and calculating the neutron coincidence counting rate 第一步,以ain ? li源為中子源,計算鈾的誘發裂變中子產生二率及空間分布;第二步,以鈾的誘發裂變中子為中子源,計算化根’ ne管的總中子計數率及時間分布;第三步,計算中子符合計數率。

The author and two colleagues recently used measurements of xenon gas ( a product of uranium fission ) to deduce that one of these ancient reactors must have operated with a duty cycle of about half an hour on and at least two and a half hours off 作者與兩位同事最近透過氙氣(鈾的核分裂產物)的測量推測,這些遠古反應器其中之一必定曾經以運作半小時、關閉兩小時半的周期進行核反應。

None of the xenon isotopes we measured were the direct result of uranium fission 我們所測量到的氙同位素,根本都不是直接由鈾的核分裂而來。
