This thesis consists of three main parts of the research work on the syntheses, structures and reactivities of the olefin-coordinated transition metal carbene and carbyne complexes. In chapter 1, on the basis of our previous research works on the reacitivites of the cationic carbyne complexes of transition metals with metalcarbonyl anions, we explored the reactions of the cationic carbyne complexes of manganese (1) and rhenium (2) with polymetalcarbonyl anions, and developed a new method for the preparations of heternuclear trimetal bridging carbyne complexes.

These phenomena are explained as follows thatduring the hydration of α-hemihydrate gypsum, cations have significance influence on theζpotential of α-hemihydrate gypsum, thereby the dispersed state and the dissolving ratesof α-hemihydrate gypsum are changed. But anions have slight influence because it isdifficult that anions enter the double-layer.

In borate or phosphate buffered NaCl solutions with a constant total concentration of borate or phosphate, E_ increases with an increase in pH. With the increase of the concentration of chloride ions, E_ decreases markedly in the test solutions. Moreover, the buffer capacity and concentration of nonaggressive anions in the test solutions also exerts some effects on the crevice corrosion of Type 304 stainless steel. Furthermore, the cooperative inhibition effect of the environmental factors on crevice corrosion was investigated. The potential of crevice corrosion E_(cc shows a strong dependence on a parameter J, which was called as general environmental factor and defined as the product of concentration of nonaggressive anions, pH, buffer capacity and concentration of chloride ions.
