When extracting total DNA of the algae, if the cells were pre-treated by alcohol+ether (1∶1), their gelatinous sheathes were broken and the production of total DNA increased by 3-4 times.

用乙醇乙醚混合液对该藻作预处理后，破坏了其胶质被，再经常规方法提取总DNA ，其得率提高 3- 4倍。

Study is made of a new process for directly extraction of the cobalt oxalate from ammonium oxalate in the acid solution directly dissolved from lithium cobaltate.

研究了从钴酸锂直接溶解后的酸溶液中用草酸铵直接提取草酸钴的新工艺，采用氟盐将酸溶液中的铝完全全络合，然后用草酸铵在pH为2，温度60℃下沉钴，再在马弗炉中煅烧成氧化钴，所得产品可达到Co2O3？

The ray from the plasma lamp will go through into the light pipe with little incident angle after reflection by the reflector, and then the total reflection of the ray will occur among the prismatic reflecting films. Some ray may come to the end mirror and will be reflected back, and only a little of rays pass through the prismatic reflecting films, most of the rays will go forward by the action of the bottom light extracting surface and go out to be lighting.

等离子灯球发出的光线经过反射器反射后，以很小的入射角进入到导光管，光线在棱镜反光膜管子内进行全反射，到达丙烯酸树脂管端底镜面的光线，再反射回到管子内部，只有少量的光线透过棱镜反光膜出来，最终大部分光线通过管子底部的光线提取面引出管外，传送到所需要照明的宽广区域（见图7）。

Press the axle end to the bottom, draw the brake wheel 2, and make it close to the tape of behind cover, revolve the nut 5 clockwise, make it touch with the brake wheel, continually revolve the nut for one to one and a half ring, lock the screw and wind window.

4顺轴下压转轴端部至底，提取制动轮2使其制动环与后端罩3锥面贴合，顺时针方向旋转锁紧螺母5，使其与制动轮端面接触，再将锁紧螺母继续按顺时方向转一圈至一圈半，上好锁紧螺钉和通风窗，调整完毕。

Automatic color transfer effectively solves this issue. Carve up Roseau and subtractive clustering is applied in this paper. Completely automatic algorithm implementation is realized. In clustering, pixels are selected according to their brightness, and those with larger data density are cluster to sample block. First of colors in the same block are transferred first, others are transferred later.

本文将网格划分减法聚类应用到颜色迁移中，完全实现算法的自动化，聚类方法按照亮度值的大小依次聚类，从各个聚类域中提取出数据点密度较大的像素点集组成样本块，首先对每个样本块间进行颜色迁移，再完成样本块以外的其他像素的颜色迁移。
