于是，100的常用对数(log100)是2，因为102=100。

Signals, equal to ten times the common logarithm of the ratio of the two levels.

强度'。''方面的相对差别的单位，相当于两个水平的比率的常用对数的十倍

For example, 10 3 = 1,000; therefore, log 10 1,000 = 3. The kinds most often used are the common logarithm and the natural logarithm.

如，10 3=1，000；于是log 101，000=3。通常使用的有常用对数和自然对数

Returns the common logarithm (base-10 logarithm) of x .

返回 x 的通用对数（以10为对数）。

A unit used to express relative difference in power or intensity, usually between two acoustic or electric signals, equal to ten times the common logarithm of the ratio of the two levels.

分贝通常表示两个声音信号或电力信号在功率或强度方面的相对差别的单位，相当于两个水平的比率的常用对数的十倍

It is customary to plot the amplitude ratio in decibels and the phase angle in degree against the common logarithm of the input frequency.

在绘图时通常幅值用分贝表示，相角用度表示，输入信号的频率按常用对数取值。

This algorithm mainly consists of two parts: auto shutter control based on cubic interpolating polynomial of common logarithm of the image average gray and image grey stretch technique based on experiment data analysis.

结合图像处理中的灰度拉伸技术，实现了一种方便、稳定及高精度的调光。其算法主要由基于场景灰度均值对数的三次多项式插值函数自动快门控制和图像灰度拉伸实现。

Another important result is that, which can be easily drown from the figure of probabilities of the states vs pump power with different x, or the common logarithm figure of the populate probabilities vs x , the increasing of the concentration of Er ions increase both energy transfer which populate the state and the cross relaxation process which depopulate the state, but the total result is that ion number of high lying states increase with concentration.

从不同掺杂浓度下各态布居几率或粒子数与光强的变化关系图可以看出，虽然掺杂离子浓度的增大同时增强了产生上转换荧光能态布居的能量迁移上转换过程和消耗该能态布居的交叉驰豫过程，但两者竞争的结果是较高的掺杂浓度对产生高能激发态的粒子数有利。

The experimental results have shown that the common logarithm values of transverse rupture strength lgσ〓 increase with the increase of fractal dimension D〓, and has a linear equation relationship. The microfracture fractal model of cermets has been founded and the estimated fractal dimension formula of fracture surfaces proposed.

建立了颗粒型复合材料金属陶瓷断裂的微观fractal模型，提出了计算断口表面分形维数的公式，指出断口分形维数依赖于测量码尺的选择，对金属陶瓷来说其临界测量码尺为0.07μm。

Freundlich adsorption exponent (0.6382, 0.6844) and common logarithm of adsorption index (1.6932, 1.7115) for peat and humin are almost equal. They indicate that humin may control the binding ability of Ni(superscript 2+) onto peat. The results show that humin can act as a potential material for permeable reactive barrier.

泥煤和胡敏素吸附镍Freundlich吸附指数(0.6382， 0.6844)和吸附系数常用对数值(1.6932， 1.7115)数值非常接近，表明胡敏素组分可能决定了泥煤的吸附能力，因此胡敏素将可作为有潜力的可渗透性屏障地质材料。
