I n the morphological approach of image processing, we propose edge feature extrac tion, morphological gradient, the representation of morphological skeleton, and the application of the open and close morphological transforms in image processi ng such as image peak, valley detectio.

Experimental results show that it is suitable to choose the morphological skeletal function as the structural feature of the kernel structure.

Based on the fractal mathematical theory and the image processing technology,the authors have deeply investigated bone scaffolds microstructure and have established the bone scaffolds porous medium fractal dimension,porosity,permeability mathematical models.

In order to understand further the role of calixarene skeleton with cone conformation in recognition of spectroscopic acceptors, a comparative study was made on calixarenes and their monomers, including the design and properties of calixarene-based chromoionophore for Ni 2+ and especially fluorescent acceptor for Cu 2+.
