Abstract: | In this article, the rare earth solution with low concentration isadopted to treat the tapping face and the orthogonal experiment reveals that theaverage resin-producing yield of the tapping face treated by the optimizing com-bination A_1B_2C_2 increases by 31.6 percent than that of the check tapping faceeach tapping time. The optimizing combination A_1B_2C_2 is that the rare earth so-lution is 0.5 percent, the drug is applied in August and the interval time of drugapplication is 3 days. |
