fissile的音標是["f?s?l??]，意思是可裂變的。

速記技巧：fissile取自單詞“fissionable”，可以簡化為fissile。同時，也可以用“fi-si-li”進行快速記憶。

fissile這個詞源自拉丁語，意思是“分裂的，裂開的”。它的變化形式主要有復(fù)數(shù)形式fissiles，過去式fissioned，現(xiàn)在分詞fissioning。

1. fission - 裂變，核裂變，是fissile的動詞形式，表示分裂或分解的過程。

2. fission bomb - 裂變炸彈，是一種利用核裂變原理制造的武器。

3. fissionable - 可裂變的，指能夠進行核裂變的物質(zhì)。

4. fission reactor - 裂變反應(yīng)堆，是一種利用核裂變過程產(chǎn)生能量的裝置。

5. fission track - 裂變軌跡，指核裂變過程中產(chǎn)生的放射性痕跡。

6. fission product - 裂變產(chǎn)物，指由核裂變產(chǎn)生的放射性物質(zhì)。

7. neutron - 中子，是核裂變過程中的重要粒子。

8. neutron bomb - 中子炸彈，是一種利用中子殺傷力的武器。

9. neutronium - 中子物質(zhì)，指由大量中子組成的物質(zhì)。

10. fission-fusion process - 裂聚過程，是一種理論上的過程，涉及到裂變和聚變的相互作用。

以上這些單詞都與fissile這個詞有密切的聯(lián)系，反映了核科學(xué)和物理學(xué)中的一些基本概念和過程。

英文小作文：

Fissile materials are essential for the production of nuclear energy, which has the potential to provide clean, safe, and sustainable energy sources for future generations. However, fissile materials are also a potential threat to national security and international peace and security, as they can be used in the development of nuclear weapons and other nuclear applications. Therefore, it is crucial to ensure that these materials are safely and securely managed and used in a responsible manner. At the same time, we must also explore alternative energy sources and technologies that are less harmful to the environment and human health, and that can help us to move towards a more sustainable future.
