The number of autoterophic bacteria were significantly lower than the heterotrophic bacteria. Majority of 21 strains of heterotrophic bacteria that isolated from water body were Pseudomonas. Majority of 25 strains of heterotrophic bacteria isolated from sediment were bacillus, microccus and Pseudomonas.Three genus of autotrophic bacteria were sulphuret bacteria, nitrify bacteria and nitrosobacteria that were capable of oxidizing H2S, S, FeS, oxidizing NH3 to NO2 and NO2 to NO3 respectively.

试验稚鳖池水中共分离出21株异养细菌，其中优势菌为假单胞杆菌属细菌；底泥中共分离出25株异养细菌，其中优势菌为芽胞杆菌属细菌，微球菌属细菌假单胞菌属细菌，三种自养细菌分别为具有氧化硫化氢、元素硫或硫化亚铁的硫细菌；具有氧化氨为亚硝酸的亚硝化细菌和能将亚硝酸进一步转化成硝酸的硝化细菌。

The aromatic position isomers, such as xylene and nitrotoluene, were separated well. Moreover, some chiral compounds including alcohol, amine, ester etc., were also resolved.

In this dissertation, considering the influence of transverse shearing deflection and noncoincidence of torsion center and gravity center, the equilibrium formulas of variable-curvature box-girder with rectangular cross section were established. Based on deformation expression of arbitrary point on the girder and relationship between inner forces and displacement equations, considering noncoincidence of torsional center and gravity center, the governing differential equations for variable-curvature box-girders were generalized.
