ABSTRACT The aim of the project is to prepare the high temperature superconducting thin films which can satisfy the need of future applications in the field of power transmission. By using biaxially textured Ni (001) and Ag (110) as substrates, the YBCO films with high critical current were obtained under the optimized deposition conditions. Some results were obtained as follows: We developed a simple approach to prepare YBCO films doped with Ag nanograins.

The main steps include as follows: CO2 is led into the mother liquor of sodium meta-aluminate to carry out carbon content decomposing; the primary separation between the aluminum and the gallium is realized by primary carbonatation to filter out sodium hydroxide; secondary carbonatation is carried out on the filtrate to obtain the deposit of the complex salt of gallium and aluminum; a sodium carbonate crystal is obtained after the filtered filtrate is condensed and vaporized; the deposit of the complex salt of gallium and aluminum is dissolved in the mother liquor of sodium meta-aluminate; the processes are repeated until the proportion of gallium and aluminum in the complex salt of gallium and aluminum is larger than 1/340; then the complex salt of gallium and aluminum is added into the NaOH liquor and electrolyzed, thus obtaining the metal gallium with a purity larger than 99.9 percent which reaches the level of 3; simultaneously, the byproducts of the aluminum hydroxide and the sodium carbonate during the process of carbonatation by steps are obtained.

By this iterative method ,the solvability of the matrix equation can be judged automatically.When the matrix equation is consistent ,then,for any initial centrosymmetric matrix pair ,a centrosymmetric solution pair can be obtained within finite iteration steps in the absence of roundoff errors, and the least norm centrosymmetric solution pair can be obtained by choosing a special kind of initial centrosymmetric matrix pair.

With increasing monomer concentration inside the disperse phase, the monodispersity of emulsions became slightly worse and the mean diameter of emulsions gradually became smaller. Monodisperse monomer-containing emulsions were obtained when the SPG membrane pore size was larger than 1.0 μm; however, when the SPG membrane pore size was smaller than 1.0 μm, no monodisperse emulsions were obtained because of the formation and chokage of p-phthalic acid crystals in the pores of the SPG membrane.

当SPG膜孔径大于1.0 μm左右时，可得到单分散的含TDC单体乳液；而当孔径小于1.0 μm左右时，水分子更容易扩散并溶解到油水界面甚至油相内部与TDC生成对苯二甲酸，TPA积累到一定程度在油水界面上析出将膜孔堵塞，从而无法制得单分散乳液。
