Standard curve folded edit this section to avoid other factors affecting hydraulic motor wholesale, often measuring a series of standard solutions of different concentrations of the substance in a certain wavelength absorbance. In the vertical axis represents the absorbance or transmittance, the horizontal axis is the concentration to a standard curve for quantitative determination routine. In the quantitative measurement, select the appropriate wavelength for the quantitative determination of horizontal important, commonly used absorption peak of the absorbance band. Relatively flat absorption band peak in a certain wavelength range smaller hydraulic motors installed, the absorption intensity change by other factors such as the small hydraulic motor disturbances such slits sale, so the error is also small. Nominal value scale and scale of the order of addition, subtraction can not be, but the value scale spacing can be addition and subtraction. However, since the origin is arbitrarily set, it can not perform multiplication and division. For example, the difference between 5 ℃ and 10 ℃, can be said between 15 ℃ and 20 ℃ difference is the same, are 5 ° C. But I can not say 20 ℃ is more than 5 ℃ 4 times higher temperatures. Meaning the ratio scale is absolute, meaning that it has a "no" amount of the origin 0. Length, weight and time are measured by the ratio of the scale range. The difference between the measured value and scale-ratio are comparable. For example: the difference and the difference between 10 minutes and 15 minutes of between 5 minutes and 10 minutes are 5 minutes, 10 minutes 5 times 2 minutes. The ratio of scale can be arithmetic operations. Hydraulic motor hydraulic motor detection _ _ by the Jinan Jing Jing Chong Chong hydraulic hydraulic machinery Limited.
