根据1990～1995年布氏菌病全国监测点羊、牛、猪、人的血清学阳性率资料,利用灰色模型和加权平均法,建立了两种数学预报模型,将两种预报值取算术平均进行综合后,给出了1996～1997的布病阳性率预报值。
According to the serological positive rate data of sheep, cattle, pigs and human at the national monitoring sites of brucellosis from 1990 to 1995, two mathematical forecast models were established by using the gray model and the weighted average method. The two forecasting values were averaged After the synthesis, the prediction value of the cloth disease positive rate from 1996 to 1997 is given.
