fission的音標為[?f??n]，基本翻譯為“分裂；裂變”，速記技巧為：fission（裂變）→分（fi）散（sin）→分裂。

fission的詞源：

詞根“fiss”和“fission”來自拉丁語，意為“to split”。

fission的變化形式：

過去式：fissioned。

7. fissionable material 裂變物質

雙語例句：

1. Nuclear fission is the process by which atoms split and release energy. 核裂變是原子分裂并釋放能量的過程。

2. The power of a fission bomb is directly proportional to the amount of fissile material used. 裂變炸彈的威力與所用易裂變材料的量成正比。

3. Fission reactors are used to generate electricity and are considered to be a clean source of energy. 裂變反應堆用于發電，并被認為是一種清潔的能源。

4. Fission products are radioactive substances that are created when an atom undergoes fission. 當原子發生裂變時，會產生放射性物質。

5. The process of fission releases a large amount of energy, which can be used for various purposes. 裂變過程釋放大量能量，可用于各種目的。

6. Fission reactors are considered to be safer than other types of nuclear reactors because they do not produce radioactive waste. 裂變反應堆被認為比其他類型的核反應堆更安全，因為它們不產生放射性廢物。

7. Fission bombs are considered to be more powerful than fusion bombs because they release more energy per atom split. 裂變炸彈被認為比聚變炸彈更強大，因為它們每分裂一個原子就能釋放更多能量。

英文小作文：

Fission is a process that occurs in atoms and releases energy. It involves the splitting of an atom, which releases a large amount of energy that can be used for various purposes, such as generating electricity or creating explosives. Fission reactors are used to generate electricity and are considered to be a clean source of energy because they do not produce radioactive waste. However, there are also concerns about the safety of fission, especially when it comes to the handling of radioactive materials and the potential for accidents or terrorist attacks. Nevertheless, fission has played an important role in the development of nuclear power and continues to be an important part of the nuclear energy industry today.
