A data acquisition and data analysis software for the fast fluorscence kinetics fluorometer of our laboratory is redesigned and recompiled using assembly and BASIC language. The data acquisition rate in the fast rising part of the fluorescence kinetics curves is one order faster (100μs/point) than the old one. It can measure fluorescence parameters, such as Fo and Fi more accurately for calculation of the relative content of inactive PSⅡ, etc.

结果表明，随着采样次数的增加，拖曳力和惯性力的偏斜度和峰度驱于收敛。

A warning signal from the system which indicates high EC or EC ratio of a dairy cow is used to inform the milker to pay attention to the suspected cow. The detection thresholds of EC and ECR to determine whether a quarter or a dairy cow is infected with mastitis correspond with the criterion of SCC = 500×103 cells/ml for quarter foremilk of a dairy cow. The performance of online system for mastitis detection in dairy cows is evaluated with several methods, such as the detection thresholds, running analysis and discrimination analysis.
