coefficient

coefficient音标为英 [ˌkəʊɪsɪfɪənt]、美 [ˌkoʊɪsɪfɪrnt]。

基本翻译为“系数；乘积；乘数；系数（或乘数）的数值”。

速记技巧可以记成：coi（谐音：同胞）s（英文单词“乘”的首字母）f（英文单词“因子”的首字母）ent（英文单词“表示”的缩写）。意思是同胞在乘法中表示乘数，因此可以快速记住这个单词。

Coefficient这个词的英文词源可以追溯到拉丁语“co-”和“factor”，表示“共同”和“因素”的意思。它的变化形式主要有复数形式“coefficients”和过去式“coefficientized”。

相关单词：

“coefficient”这个词本身是“co-”和“factor”的合成词，意为“系数”。在数学中，它常常用来表示两个量之间的比例关系。

“coefficiently”是一个副词，意为“以系数的方式”，常用于描述数学运算的结果。

“coefficientize”是一个动词，意为“赋予系数”，常用于数学公式的推导过程中。

“coefficiently”也是一个形容词，意为“系数的”，常用于描述与系数相关的性质或特征。

“coefficiently”还可以作为副词，意为“相对地”，常用于比较两个量之间的比例关系。

以上这些单词都与Coefficient这个词有着密切的联系，并且在不同的语境中有着广泛的应用。这些单词的出现也反映了数学在语言中的重要地位和影响力。

英文小作文：

Coefficients play a crucial role in many aspects of our lives, from physics to engineering to economics. For instance, the coefficient of friction helps us understand how two surfaces interact when they come into contact, while the coefficient of thermal expansion is crucial in predicting how materials behave under changes in temperature. These coefficients help us understand and predict the behavior of various systems and variables, allowing us to make informed decisions and take appropriate actions.

On a personal level, coefficients also have a significant impact on our daily lives. For example, the coefficient of friction between our shoes and the ground determines how easy it is for us to walk or run, while the coefficient of viscosity in our bloodstream helps maintain our bodily functions and keep us healthy. Understanding these coefficients and how they work can help us make better decisions and live healthier lives.

In conclusion, coefficients are an essential part of our world and play a crucial role in many aspects of our lives. Understanding and using these coefficients can help us make informed decisions and live healthier, more productive lives.
