The results show that the maximum growth quantity of Nocardia can be achieved after culturing 120 h and obvious selective adsorption of Nocardia on the surface of pyrite and sphalerite can be detected. The maximum adsorption rate on the surface of pyrite is 96.99%, whereas it is less than 20% in the case of sphalerite. Adsorption equilibrium can be attained within 20 min on the surfaces of the two minerals. pH value is the key factor influencing upon selective adsorption, and the difference of adsorption quantity on the surfaces of two minerals is apparent when pH is between 4 and 10. Slurry concentration over 6 g/L is favorable to selective adsorption. Nocardia cell concentration, stirring speed and temperature have no obviously effect on selective adsorption.

In the dry sliding experiments of composites, friction coefficients decreased with the increase of load. Plastic deformation happened in the worn surface where Fe element was found, so PAM micro-fiber supported part of the load and prevented the further deformation. On the condition of high speed and high load, the worn surface of PAM1/nylon 6 composites was nearly melted and formed comparative uniform transfer on the surface of steel, which accounted for the rather low wear mass loss. The infrared analysis showed that the a small quantity of transition of crystal form from α into γ of nylon and its composites happened during the friction because of the high temperature and strong sheering strength.

Guanine can quench the phthalhydrazidylazoacetylacetone's ECL in acid medium, and the linear concentration range of guanine relative to the ECL intensity is from 2.0×10~(-6) to 1.0×10~(-5) mol/L.The mechanism of phthalhydrazidylazoacetylacetone's ECL on the surface of ITO glass has been discussed according the experimental phenomenon.The phenomenon of ITO self-luminescence has also been studied.It has been found that the machanism of phthalhydrazidylazoacetylacetone on the surface of ITO in different medium is dissimilarity. The phenomenon of ITO self-luminescence may be caused by the interaction of the active oxygen element and ITO's surface.
