The common system is used in numerical work almost exclusively . 在数值计算中，几乎只使用常用对数。

To find the common log of a number, we first write it in scientific notation with one figure to the left of the decimal point . 为了求一个数的常用对数，首先按照科学计数法把它写作小数点左面具有一位的数。

Thereafter , the rfq - pcr method for the detection and enumeration of s . costatum cells is established with primer6 ( f / r ) and taqman6 . the regression curve for enumeration is delineated according to the development of the fluorescent densities in the rfq - pcr with the increasing number of s . costatum cells . the regression equation is y = - 3 . 3427x + 43 . 443 , in which x indicates the log10 of cell number , and y indicates the ct values , with r2 of 0 . 9788 以rfq一pcr中实际细胞数的常用对数值为横座标，以测得的ct值为纵座标，绘制出了定量检测的标准曲线，该曲线的回归方程为: y =一3 . 3427x + 43 . 443 ，其相关系数是: rz二0 . 9788 ， ct值的标准估计误差为sy ’ x二0 . 6741 。
