Holding time 1 min at 615～595 ℃ and isothermal holding at 600 ℃ about 1～10 min for A356 Al alloy, the evolution characteristics of semi-solid primary phase about A356 Al alloy at different isothermal holding temperatures and time were investigated.

Non-chemical bond association structures in Fanzhi brown coal and their evolution were studied by the integration of hydrous pyrolysis and CS_2/NMP extraction.

On the basis of studying the existing literatures on the reservoirs home and abroad,the particularity of the volcanic rock reservoirs,the types and the genesis of reservoir space,the evolution feature of the space and the types of reservoirs are summered.

On the basis of investigation of the research results of volcanic reservoirs at home and abroad, this paper summarizes the types and geneses of reservoir space, the evolution of reservoir space and the controlling factors of reservoir formation.

Using the deformation data of the last 50 years in Shanxi area,the deformation field and its space time evolution characteristics are studied.
