Since there exists some disadvantages such as poor mechanic properties and much higher burning rate pressure exponents (?1) in the fundamental formulations, this work is devoted to the improvements of combustion characteristics and mechanic properties of LOVA propellants. The effects of the crystal shape, size and contents of nitroamine particles, the types of binder, plasticizer and surface-active agents and the contents of NC on combustion performance are studied by closed bomb tests. In the mechanic properties tests, the effects of the types of binders, plasticizers and solid fillers, the interaction between binders and solid fillers and technological procedures on propellant mechanic properties are researched.

The activty of SOD in vesicle solution is then determined. But still no apparent superactivty is found due to the following reasons: 1. The lowered dielectric constant reduces not only the self-oxidation rate of pyrogallic, but also the activity of SOD; 2. There are no efficient enough interaction between vesicles and SOD.

在上述体系中进行的SOD的活性研究中，没有发现表观超活性，估计是两方面的原因：一是囊泡周围低的介电常数同样也降低了SOD酶的活性，二是由于表面活性剂浓度较小，仅为0.5％左右，使得囊泡体积分数较小，不能与SOD酶发生充分有效的结合。

The effects of many parameters, such as the amount of surfactant, airflow rates, pH, NaCl, ethanol and temperature on the solvent sublation were studied. Experimental results showed that a ratio of surfactant to Pb-dithizone complex (2∶1) was the most effective for the removal, with over 97.4% Pb removed from the aqueous solution in 40 min by solvent sublation, at the value of pH 12.6.The solvent sublation process followed first order kinetics. A characteristic parameter, apparent activation energy of attachment of the sublate to bubbles, was estimated at a value of 2.08 kJ/mol.

Contrasted with the activity of the same reaction in oil-water double phased system, the hydrolyzing behavior of Camlicla Lipolytica Lipase in reversed micellar systems is much like that in oil-water double phased system. The stability and catalyzing activity are both enhanced and give rise to "superactivity". except in reverse micelles composed of cationic surfactant.
