eutectics的音標為[i??tek?ts?ks] ，基本翻譯為“合金學(xué)”，速記技巧為：合金學(xué)（eutectics）——優(yōu)（e）特（t）吃（k）西（s）。

Eutectics這個詞源自希臘語，意為“完全融化”。它的變化形式包括名詞形式eutectic（共晶）和形容詞形式eutectic（共晶的）。

相關(guān)單詞：

1. Eutectic合金（共晶合金）：一種由兩種或更多種金屬或合金，在一定條件下形成的合金，其熔點低于任何組成成分的單一金屬。

2. Eutectoid（亞共晶的）：指具有亞共晶組織的合金。

3. Eutectic point（共晶點）：指合金中不同組分達到共晶成分時的溫度點。

例如，在冶金學(xué)中，我們經(jīng)常討論合金的成分和溫度，以了解其可能形成的組織和結(jié)構(gòu)。這些概念都與eutectics密切相關(guān)，并幫助我們理解金屬和合金的特性。
