Semilogarithmic

释义 Definition

半对数的;半对数坐标的:指在图表或尺度中,一个轴使用对数刻度(log scale),而另一个轴使用线性刻度(linear scale)。常用于展示指数增长/衰减数据(如人口、放射性衰变、复利等)。
(也可指“半对数图/半对数坐标系”:semilogarithmic plot/graph/scale

发音 Pronunciation (IPA)

/smilrmk/

词源 Etymology

semi-(“半、部分”)+ logarithmic(“对数的”,源自 logarithm “对数”)构成,字面意思是“部分采用对数的”。在数学、工程与数据可视化里,通常特指“一轴对数、另一轴线性”的坐标表示方式。

例句 Examples

The data looks like a straight line on a semilogarithmic plot.
在半对数图上,这组数据看起来像一条直线。

Because the concentration decays exponentially, we graphed it on a semilogarithmic scale to estimate the rate constant more accurately.
由于浓度呈指数衰减,我们把它画在半对数坐标上,以更准确地估计速率常数。/p>
