Through a discussion on the suffix features of miniterm and maxiterm ,this paper offers a suffix calculating approach to miniterm and maxiterm in principal disjunctive normal form,principal conjunctive normal form determined by disjunctive normal form,and conjunctive normal form of propositional formula.

通过极小项和极大项的下标特征的讨论，给出了由命题公式的析取范式、合取范式而确定的主析取范式、主合取范式中的极小项、极大项的下标计算方法，从而简化了由繁杂的命题公式推演或真值计算求主范式的计算过程。

The results showed that the significance of the effects of these factors on the oil extraction efficiency decreaseed in the order:extraction pressure, time, temperature and entrainer dosage, and the maximum extraction efficiency of watermelon seed oil could reach 52.18% under the extraction pressure of 40 MPa, temperature of 45℃, time of 150 min and the ethanol dosage of 7%.

结果表明，影响西瓜籽油萃取率的因素主次顺序为：萃取压力＞萃取时间＞萃取温度＞夹带剂用量；最佳提取条件为萃取压力40 MPa，萃取温度45℃，萃取时间150 min，夹带剂乙醇用量7%。在最佳条件下西瓜籽油萃取率为52.18%。

METHODS: The location of 65 consecutive patients with Wharton's duct calculus was analyzed by bimanual examination of the floor of month and bite film of the mandible. Of 65 patients, 57 had the stone removed via intraoral duct incision or sialoendoscopy, 8 by submandibular gland excision. After operation, the shape and size of the calculus were observed and measured.

对连续就诊的65例下颌下腺导管结石患者通过口底双合诊和下颌横断片判断结石的位置，手术取石，其中57例经口内直接切开导管取石或内镜辅助下取石，8例行下颌下腺切除术后取石，观察、测量术后所取结石的形状和大小。

In this paper the technology of the CO2 supercritical fluid extraction of the oil from camphor tree seed were studiedin the lab.

对超临界CO2萃取樟树籽油的工艺进行了研究，探讨了萃取压力，萃取温度和CO2流量对樟树籽油萃取的影响，在萃取压力20MPa、萃取温度40℃、CO2流量35kg/h条件下，萃取2h，樟树籽油的萃取率可达94.3%。
