The solutions were found to be good agrees with experimental results. The transfer characteristic of air dry/wet bulb temperature and spraying water temperature were discussed. The LMTD method based on this mathematical model is applicable to design and verify for the plate wet air cooler. The ratio of the wet bulb heat transfer coefficient to the heat transfer coefficient under air-cooled conditions was investigated theoretically and experimentally. The relative errors of the ratio between theoretical and experimental valves are small than 7 percent.

AlTiN coating has inconspicuous anti-wear effect on carbide.(3) With the introduce of graphite chips bwteen the frictional surface, the effect of graphite chip on the sliding friction and wear behavior of frictional pair was studied. The results show that graphite chips can reduce the coefficient of friction and frictional temperature, and make the coefficient of friction decrease with the decrease of normal load and rise of sliding speed.
