对数刻度

Limits of technical index frequency: 100kHz~50GHz, depend on probe power limits:- 70~+44dBm(100pW~25W), depend on probe power probe: As compatible as probe of HP8480 series power dynamic limits: 50dB, 10dB pace takes indication unit: Absolute power: W, DBm; Relative to power: Per cent, DB resolution: In resolution of logarithm mode optional 0.1, 0.01 with 0.001dB; 1% what perhaps be complete scale in linear mode resolution, 0.1% with 0.01%.

技术指标频率规模：100kHz~50GHz，取决于探头功率规模：-70~+44dBm(100pW~25W)，取决于探头功率探头：与HP8480系列功率探头兼容动静规模：50dB，10dB步进显示单元：相对功率：W，dBm；相对功率：百分比，dB 分辨率：在对数模式可选择的分辨率0.1，0.01和0.001dB；或者在线性模式分辨率为全刻度的1%，0.1%和0.01%。

That tenth of a point on the logarithmic pH scale actually means a roughly 30 percent increase in acidity.

因著海洋pH值从上个世纪8.2变为8.1，被称为有孔虫的微小生物壳的厚度变薄了。pH值是对数刻度，这0.1实际上就是酸度大致增加30%。

The reflection instrument measure the proportion of light that is absorbed by the printed ink film, but this is converted and display in the logarithmic optical density scale.

反映器具测量被印刷墨水电影吸收的光的比例，但是这被转换而且在对数的光学密度刻度显示。

The logarithmic scale hides the scale of the increase. Because this represents trillions-fold increase since the 1890 census. In 1950s they were shrinking vacuum tubes, making them smaller and smaller. They finally hit a wall.

这个对数表隐藏了增长的刻度，因为这表示自1890年统计开始，几兆倍的增长。1950年代他们缩小真空管，将它们越做越小，最后他们碰了壁。

In 1614, John Napier discovered the logarithm which made it possible to perform multiplications and divisions by addition and subtraction.

1620年，牛津的埃德蒙·甘特发明了一种使用单个对数刻度的计算工具，当和另外的测量工具配合使用时，可以用来做乘除法。

To show it, in fact, we have to move away from a linear scale on the Y axis (where each tick mark represents an additional 20 units) and adopt a logarithmic one (where each tick mark represents a factor of 10 increase).

事实上，为了方便显示，我们必须改变Y轴的线性刻度（其中每个刻度表示20单位）而采用对数刻度（其中每个刻度表示增加10倍）。
