geometric mean的音標(biāo)為[d?i??metr?k mi?n]，基本翻譯為“幾何平均數(shù)”，速記技巧為“幾何均數(shù)，幾何圖形求平均”。

Geometric mean 的英文詞源可以追溯到古希臘數(shù)學(xué)家歐幾里得（Euclid），他提出了幾何學(xué)的定義和基礎(chǔ)理論。

Geometric mean 的變化形式主要有復(fù)數(shù)形式 geometric means，以及其比較級和最高級形式 geometric mean, geometric meanst, geometric meansthe most。

相關(guān)單詞有：

magnitude：意為大小或量度，與 geometric mean 有一定的關(guān)聯(lián)，表示幾何的數(shù)量或規(guī)模。

arithmetic：意為算術(shù)的，與幾何學(xué)無關(guān)，但可以表示計算或運算的過程。

geometrical：意為幾何的，與幾何學(xué)相關(guān)，常用于描述幾何形狀或性質(zhì)。

dimension：意為維度或尺寸，與幾何學(xué)中的維度概念有關(guān)。

curvature：意為曲率或彎曲程度，與幾何學(xué)中的曲線形狀有關(guān)。

perspective：意為透視圖或視角，與幾何學(xué)中的透視原理有關(guān)。

conic section：意為圓錐截面或圓錐曲線，與幾何學(xué)中的圓錐形狀有關(guān)。

plane geometry：意為平面幾何學(xué)，是幾何學(xué)的基礎(chǔ)課程之一。

solid geometry：意為立體幾何學(xué)，是幾何學(xué)的延伸課程之一。

以上單詞都與幾何學(xué)相關(guān)，并可以用來描述幾何學(xué)中的概念和性質(zhì)。

英文小作文：

The geometric mean is a mathematical concept that measures the average value of a set of numbers or ratios. It is a way of taking into account all values in a set and calculating a single number that represents their overall average. In practical terms, the geometric mean can be used to calculate averages of measurements that are not normally distributed, but have a certain degree of variability and growth potential.

For example, consider a company that is growing its revenues and profits at a geometric rate of 20% per year. If we calculate the geometric mean of these growth rates, we can see how all of the revenues and profits are contributing to a larger overall value, even though some may be larger than others at any given time. Similarly, in a financial context, the geometric mean can be used to calculate the overall value of a portfolio or investment strategy, taking into account the growth potential of each asset or investment.

In summary, the geometric mean is a useful tool for understanding and analyzing data sets that have variability and growth potential, and it can be applied to various contexts, from business growth to financial analysis.
