Recent results indicate that （1） Oryzeae is monophyletic and falls into two main clades corresponding to the traditionally recognized subtribes;（2） Close affinities of the monoecious genera are not supported, suggesting the multiple origins of unisexual florets;（3） Previous recognition of three monotypic genera （Hydrochloa, Porteresia and Prosphytochloa） is not justified;（4） Based on dating using molecular clock approach, it is estimated that Oryza and Leersia branched off from the remaining genera of Oryzeae -20 million years ago, and separated from each other -14 MYA.

In this paper, the characteristics of reservoir of reservoir of delta frontal sub-faces of PI Formation in the south of Xingshugang are studied with the data of dense well pattern and rock-mineral identification. The delta frontal sub-faces can be divided into lobate delta frontal sub-faces, branched delta frontal sub- faces and sheeted delta frontal sub-faces. The genetic types of sand bodies in different sedimentary envivonments are analyzed in detail, and the distribution and space-matching relationship of different sand bodies are studied. The micro-pore structure type is studied on the base of the thin section analysis, so the reservoir heterogeneity is studied including plane heterogeneity, interlayer heterogeneity, in-layer heterogeneity and microcosmic characteristic.

By means of molecular designing, a series of sodium branched-alkyl benzene sulfonates weresynthesized through seven process, involving Frieded-Crafts reaction, Grignard reaction, sulfonationand neutralization. Those isomers have similar structure, carbons of same quantity, but the position ofalkylaryl dissimilarity. Liner fat acid, metaxylene and halogenated hydrocarbon of different carbonnumber were used as the starting materials. Optimum processing condition was confirmed consideringinfluence of a series of reaction factors such as feed proportioning, quantity of catalysts, quantitysolvent, reaction time, temperature and pressure. Eight kinds of isomers of sodium hexadecylxylolsulfonates were finally synthesized, and characterized by FT-IR.
