Results The diagenetic grade of Permian rift basin was quite high, and the mechanical compaction resulted in the great loss of the original pore. The eodiagenesis and telodiagenesis were important to the reservoir, and fractures were the dominant hydrocarbon migrating pathway and accumulating space; In Triassic-Paleogene Formation, mechanical compaction was as important as pressolution, and the most original pore was preserved. The exodiagenesis stage of late hercynian movement, indosinian movement and Yanshan movement played the vital role in the diagenetic evolution and hydrocarbon migration and accumulation of the basin. The argillaceous dolomite and algal dolomite discaved in Permian, which were formed probably by hybrid process in high salinity lake which had the fresh water interfused in.

Through the morphological observation on silicon particles of Al-Si-Cu-Mg cast alloy, it is found, that during solution heat treatment the evolution of eutectic silicon morphology and their effect on mechanical property can be classified into three stages. In the initial stage, necking, stubbing and fragmentation of silicon particles results in an improvement in plasticity of the alloy. In the intermediate stage, the mechanical properties of the alloy attain peak values due to the spheroidization of silicon particles.
