Because the model solution is one kind of NP difficult problem, we propose a new multinomial solution algorithm, and finally take online handwriting signature verification as example to confirm the mathematical model. For 150 test signatures that we choose randomly, the successful matching rate is 91.33%, the wrong reacceptance is 6% and the wrong reject rate is 2.67%.

由于模型的求解是NP困难问题，针对这种情况，提出了一种新的多项式的求解算法，以在线手写签名验证为例验证数学模型，然后对随机的150个测试签名进行检验，结果成功匹配率为91.33%，误纳率为6%，误拒率为2.67%。

These uncontaminated explants showed that morphogenetic potential were 70%-75% and each responding explant had 1.2-1.4 shoots formation on MS medium supplemented with 2 mg/L NAA and 16 mg/L BA. Moreover, adding antibiotics (100 mg/L Rifampicin and 100 mg/L Gentamycin) to solidify MS contained 3% galactose were tested, results showed the lowest contamination rates were 20% and 1.0-1.2 shoots were regenerated per responding explant. The antibiotic treatments with 100 mg/L Rifampicin and 100 mg/L Gentamycin could reduce internal contaminants, while the addition of antibiotics into medium in vitro culture led to phototoxic phenomena of axillary explants, morphogenetic potential lost and the growth of regenerant was also inhibited.

The result showed that the dosage of 5000 IJs/plant was the best one among the 8 dosages, the average of injured legume (3.l%) with BPS was significant lower than that of 40% isofenphos-methyl solution (9.0%) and than that of tap water (53.2%). The rate of grub decrease (95.7%) and the dry weight of peanut (5941.5 kg/ha) with BPS were significant different (P.05) to that of with 40% isofenphos-methyl solution (82.7%, 303.8 kg). The application of BPS was better with irrigation than with spray. At the dosage of 5000 IJs/plant, the combination of BPS and Rhabditis sp.(4500:500) did not show conflictive, coordinate or synergistic effect to grub control.
