The article explained the study on oil extraction with petroleum ether (60~90℃) from Xanthoceras sorbifolia Bunge. through single factor test and orthogonal test. It confirmed the optimum extraction condition were as follow: particle size 2 mm,extraction temperature 90℃,extraction time 10 h,ratio of solvent to seed 5:1.

摘要以石油醚（60~90℃）为溶剂，通过单因素和正交实验优化了提取文冠果种子油工艺，得到的最佳工艺参数为：种仁粒径为2 mm，提取温度为90℃，提取时间为10 h，料液比为1：5。

The results show that though the strain is growing slower in the nitrogen-free medium than in the nitrogen-containing medium, the content of capsular polysaccharides produced by the strain in the nitrogen-free medium is higher than those in the nitrogen-containing medium, the content of capsular polysaccharides produced by the strain in the nitrogen-free medium is higher than those in the nitrogen-containing medium. The capsular polysaccharides produced by the strain in the culture which contains different mineral powders will reach the highest content on the third or the fourth day in its growing period. The strain's capability of releasing potassium from k-feldspar and biotite in the nitrogen-containing medium is higher than that in the nitrogen-free medium because in the nitrogen-free medium, the strain and its production of glucoprotein are less than those in the nitrogen-containing medium.

结果表明，尽管该菌在无氮培养条件下的菌体数量远小于有氮培养条件，但无氮培养条件下所提取的细菌多糖多于在有氮条件下培养所提取的细菌多糖；胶质芽孢杆菌在以添加钾长石粉或黑云母粉制作的无氮培养基中生长可形成大量多糖，采用丙酮法进行细菌培养液多糖提取，发现细菌培养的第3天所提多糖含量最高；胶质芽孢杆菌在以添加钾长石粉或黑云母粉制作的有氮培养基中生长亦可形成较多的多糖，且在细菌培养的第4天所提多糖含量最高；胶质芽孢杆菌在有氮条件下对含钾矿物的释钾率高于在无氮条件下的释钾率，这可能与该菌在有氮条件下生长更快、可产生较多菌体细胞有关。

The extraction amount with soxhlet extraction method was less in each extraction, and this method could be only used in experimental study. The extraction solvent of chemical extraction had pois on which could cause some pollution and toxicity.

索氏提取法每次提取的量较少，只能用于试验研究；化学萃取法的提取溶剂有毒，会造成一定的污染和毒害。

Considering that oilcans, the major part of oil storeroom object, show circular figure with higher grayness, this research adopted Sobel operator to detect the edge of images; then located the circles which have definite size through hough transform; finally, the areas of oil storm were found out and their positions were accurately located based on the circles' space distribution and their quantitative relationships.

鉴于油库目标的主要组成部分——油罐在遥感图像中呈灰度较高的圆形的特点；本文首先对遥感图像采用sobel算子提取图像边缘信息，然后利用边缘信息和改进hough变换提取图像中限定大小的圆的位置，最后再根据图像中提取出的圆的空间分布和数量关系找出油库区域并对其进行精确定位。

The optimum conditions of extracting cystine were confirmed, as follows: the waste wool pretreatment conditions are pH10, alkali solution temperature 50 ℃ and dry temperature 80 ℃; the waste wool hydrolysis conditions are hydrochloric acid concentration 32%, acid to hairs ratio 1.8:1, hydrolysis temperature 120 ℃, and hydrolys...

As the contour of a wheel rim is easier to detect than the contour of a wheel, and the contour of a wheel rim and the contour of a wheel are approximately concentric circles on the same plane, we first detect the contour of the wheel rim, the center of the wheel rim and the contacting point between the wheel and the ground, then we detect the contour of the wheel via the invariance of cross ratio under projective transformation.

由于提取钢圈轮廓比提取车轮橡胶轮廓容易，而且钢圈轮廓和车轮轮廓可以近似看作同一平面上的两个同心圆，所以在本文中，我们首先提取钢圈轮廓、钢圈圆心和车轮与地面接触点在图像上的投影，然后利用射影变换保持交比不变的性质求出车轮轮廓。
