根据１９９３～１９９８年布鲁氏菌病全国监测点羊、牛、猪、人的血清学阳性率资料，利用灰色模型，加权平均法和其他方法，建立了数学预测模型。将预测值取算术平均进行综合后，给出了１９９９～２０００年的布鲁氏菌病阳性率预测值。
According to the seroprevalence data of sheep, cattle, pigs and human at the national monitoring point of brucellosis from 1993 to 1998, a mathematical prediction model was established by using gray model, weighted average method and other methods. After the arithmetic mean of the predictive values is integrated, the predictive value of the positive rate of brucellosis from 1999 to 2000 is given.
