求翻译：根据标准品的浓度及对应的OD值计算出标准曲线的直线回归方程，再根据样品的OD值在回归方程上计算出对应的样品浓度。是什么意思？

According to standard concentration and the OD value corresponding to the standard curve linear regression equation, according to OD values ​​of samples on the regression equation to calculate the corresponding sample concentration.

Concentrations of the Products in accordance with standards and corresponding to the calculated value OD standard curve regression equations of straight lines, based on samples of the regression equations OD value calculated on the sample concentration.

Calculates the standard curve according to the standard density and the corresponding OD value the straight line regression equation, again acts according to the sample the OD value to calculate the correspondence in the regression equation the sample density.

According to the standard sample concentration and OD values to calculate the standard curve that corresponds to the linear regression equation, again based on the OD of the sample value in the regression equation calculates the corresponding concentration of the sample.
