The basic theories of mathematical morphology for binary image are stated, and the most simple structure elements of morphologic transformation for binary images are proposed and proved. The geodetic morphologic transformation models are also developed. For the purpose of improving the speed of transformation in computer, the"set symmetric difference"is introduced to adapt each model. Some new morphologic filtering models and quantitative evaluating model of filtering effects in image processing are proposed, under the applied condition. The morphologic thinning methods are studied, and two new morphologic thinning models are developed. On the basis of analyzing the characteristics of mining maps, the image vectorizing tactics and a series of algorithms are proposed, including dynamic adaptive image thresholding using two thresholds, graphic and text separation, noise removal, and multi elements extracting models with mathematical morphology. Accuracy preserving compressed vectorizing model for image vectorization is put forward to generate vector data in multi layer.

The antimicrobial test and researched was done on wide distillation of different solvents on Terpenoid, polarity separation of ethanol distillable substance, thin layer chromatography of different polarities and distillation of amylase. The results showed that the active substance distilled by 95% ethanol and V methanol: toluene=3:1 had stronger antimicrobial activity on Agaricus blazei Murrill. The antimicrobial activity of ethyl acetate was stronger than wide distilling substance with ethanol, but the water part has not antimicrobial effect. Two straps of ethyl acetate phase（Rf0.57、Rf0.63）(0.1g/ml)had stronger antimicrobial activity on Agaricus blazei Murrill, the antimicrobial zone on Pseudomonas was 19.3mm. The bacteriostatic activity of chromatography strap of water phase was rather weaker, the water solution (0.5g/g) of amylase had better effect on pathogenic fungus of Agaricus blazei Murrill, its antimicrobial zone on Aspergillus niger, Citrinin, Trichoderma viride were 10.8 mm, 7.9 mm, 5.3 mm.
