impurity的音標為[?m?pju?r?t?]，基本翻譯為“不純；雜質(zhì)；玷污；混雜”。

速記技巧：可以將單詞拆分記憶，如“im”是“不”的意思，“pure”是純潔的意思，中間加個“u”（你的名字或者任意一個物品），“tity”是名詞后綴，表示“……性”。這樣記憶不僅有助于理解單詞的含義，還可以在長時間記憶中保持清晰。

Title: Purity and Impurity

Purity is a crucial factor in many fields, from science to industry to daily life. It refers to the absence of impurities or foreign substances that may affect the performance or quality of a product or process. Purity is often measured in terms of a specific level or degree, and it is crucial to maintain high purity standards in various applications.

On the other hand, impurities are substances that are present in a product or process and may have an adverse impact on its performance or quality. They can come from various sources, such as contamination during manufacturing processes, natural elements, or even human-made additives. Therefore, it is essential to identify and remove impurities to ensure the purity of a product or process.

In the field of semiconductors, for example, purity and impurity levels are critical factors in the manufacturing process. High purity materials and processes are necessary to ensure the quality and performance of semiconductor devices. On the other hand, impurities can cause defects and reduce the reliability of semiconductor devices, which can have a significant impact on their commercial value. Therefore, it is crucial to control the impurity level in semiconductors to ensure their high-quality performance and reliability.
