actinide

actinide的音标为["æktɪnaɪd]，基本翻译为“锕系元素”，速记技巧为“锕系难记”。

Actinide是一个合成词，由“actinium”（锕）和“indefinite suffix”组成，因此其词源可以追溯到19世纪，当时科学家们发现了锕系元素。

Actinide的英文词源可以追溯到希腊语中的“actinos”，意为“光”，这个词后来被用来描述放射性元素发出的光。

变化形式：复数形式为actinides。

英文小作文：

The actinide elements are a group of highly radioactive elements that play a crucial role in the nuclear industry. From nuclear power plants to nuclear weapons, actinide elements are essential for the production of energy and weapons grade materials. However, the long half-lives and high radioactivity of these elements pose significant challenges in their disposal and management.

Actinide decay series is a chain of nuclear reactions that releases large amounts of energy, which is used in various applications such as medical isotopes and radiation therapy. However, the long-term effects of actinide exposure can be harmful to human health, which emphasizes the importance of proper waste disposal and environmental protection measures.

Actinide elements are also found in all types of waste, including nuclear waste, which poses a significant threat to the environment and human health if not properly managed and disposed of. Therefore, it is crucial to develop more sustainable and environmentally friendly methods of actinide disposal and management to ensure the safety and sustainability of our planet.
