If an additive of B less than 1.37 at.-%, some of B atoms solid-dissolved interstitially into matrix and distorted the lattice, thus the lifetime of positron in matrix dilated; the others of them segregated on vacancy-like defects and formed" filling effect", thus the mean lifetime and S parameters decreased. If B added up to 2.22 at.

On the bases of a solid solution hardening model, and considering the solubility of isoelectronic impurities in InP crystals and the elastic misfit arised from the differences of the tetrahedral radii between added impurities and host atoms, the pinning forces as large as 〓 have been obtained for isoelectronic impurities in InP.

From the structural analysis of three praseodymium complexes, we could draw a conclusion that as the dentate arms of carboxyl group on ligands elongating, the coordination numbers of Pr and the coordination modes of ligands increase, and the mean distances between metallic atoms of metallic helices existing in these complexes augment.2. By altering 5-substituting group of isophthalic acid three series of lanthanide complexes 8～19 with 5-methylisophthalic acid and 5-nitroisophthalic acid have been prepared.

Furthermore, the one-dimensional complexes 26 and 28 with strongπ-πpacking interactions are prepared from DMF solvent, which indicates that the traditional solvent volatilizing method could bring low-dimensional complex.4. By measuring the enthalpy changes of the liquid phase formation reaction for complexes a~e, and calculating the electronic densities of five 5-substituted derivation of isophthalic acid, we can make a conclusion that 5-substituted group changing of the ligand has a little influence on oxygen atoms of carboxyl groups.5. Fluorescence experiments of these complexes indicated that they could be used for luminescence materials in future.6. Using packing saturation rule we calculated and analyzed these series of complexes, and the results showed that the changes of complexes with changes of ligands could be explained from the rule.
