It is very difficult to eliminate these influence factors completely by conventional treatment. Surface properties and surface treatment of ultrafine red phosphorus and MMT and their interface properties with polymer matrices were studied in this thesis. The results were characterized by GC, FTIR, XRD, DTA, TG, XPS, UV, SEM, TEM and other physical and chemical methods. The main contents are as following: 1. The study of factors influencing ultrafine red phosphorus's invariability and phosphine liberation indicated red phosphorus undergone oxidation and dismutation reaction in air, and trace ion of iron, copper and nickel fastened water absorption and oxidation, in which the effect of copper ion was the most, while aluminium and zinc ion could slow down red phosphorus'oxidation, and silver ion had the best effect on red phosphorus moisture absorption. Inhibitors such as aluminium hydroxide, magnesium hydroxide, organic phenol and ferrous potassuim cyanide had a good effect on reducing red phosphorus moisture absorption and restraining phosphine liberation.

Based on both the strong-weak model and the strong-strong model, the instability caused by ions in equilibrium is simulated, some useful results are obtained. The results include the relation between instability growth rate and neutralization factor, the relation between instability threshold and neutralization factor, and the incoherent tune shift, the tune spread, the ion cloud distribution, the ion loss mechanism, as well as the ion accumulation limitation in the storage ring. With this understanding, we have carried out theoretical and experimental study for some ion clearing methods and their effects for the HLS ring.
