The main achievements of the project are as follows: 1 the hypothesis that a decrease in seed mass causes an increase in mean dispersal distance has been tested based on the experiments of weed dispersal by wind. The experimental results partly support the hypothesis. The results will help farmers to make an optimal strategy of weed control; 2 a statistic method for inferring probabilistic distribution function of a random variable has been developed, by which probabilistic distribution functions of weed species dispersal have been determined; 3 the reproduction structure of Bromus sterilis has been studied; 4 a more complex CA model with 25 neighborhood cells were built, which can simulate spread of a weed population. This work promotes developments in both theory and application of CA models; 5 the "mean law" in weed control has been proposed. Accordingly, the algorism of patch spring may be calibrated; 6 the "patch" and "true patch" have been mathematically defined so that herbicide can be efficiently applied; 7 simulation validates that initial configurations of weed will affect dispersal of its population and strategies of controlling it, or its distribution patterns affect its dispersal progresses.

It was found that increasing pressure for blank can improve the compactedness of blanks so as to make foam aluminium materials with homogeneous pores. Foaming temperature, as one of the main influencing factors on foaming process, should be controlled higher than the melting point of Al or Alalloy to a certain extant in order to keep a reasonable viscosity. Thus, the foam aluminum with homogeneous pores and high porosity is available. As shown by experiments, such materials should be made on conditions that they shall be protected with molten salt under 300?MPa pressure at 675~680?℃.

Solubility and stability of calcium arsenates under different CO2 pressures are studied based on the data of precipitation and solution experiments simulated by PHREEQC program. The result shows that calcium arsenates can dissolve incongruently by the effect of CO2 in high pH(pH〉8. 3)and make their solubility higher. The higher the CO2 pressure is, the lower the acidity of the incongruent dissolution is.

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.
