Beta cloth is an AO resistant spacecraft composite material,on which experiments are conducted in this paper to investigate the atomic oxygen effects,the impact of the temperature change on the atomic oxygen effects and the ultraviolet radiation effects with atomic oxygen effects ground based simulation facility.

This network structure protected the underlying materials from the AO erosion and the AO resistance of the polymer was improved remarkably;the mass loss and erosion yield decrea.

Experimental investigations of improving AO-resistant characteristics of glass fiber/epoxy resin composite filled with superfine cenospheres;

It was found that the samples filled with nano-SiO2 had an excellent AO-resistant characteristic.

Contraceptive effect of immunostimulating complexes with multi-ep itopes peptide of sperm antigens;

Immunocontraceptive effects of the recombinant attenuated Salmonella typhimurium expressing mouse sperm antigen cyritestin;

Morphology of cells was observed by atomic force microscopy(AFM) and distribution of CD8 antigen molecules of CD8+T cells were studied by a functionalized AFM tip.

That were summarized respectively which were the current status of design of veterinary reproduction control vaccines,vaccines against reproductive hormones,vaccines against gamete antigens,and vaccines to increase fertility.
