C angustipes sp nov.is similar to C baojingensis Guo,He et Bai,1992,but with longer rostrum,15-27 dorsal teeth,3-6 ventral teeth,and straighter inner margin of endopods in male 1st pleopods. C clavipes sp nov.is similar to C angustipes ,but with narrower distal and fewer spines on inner margin of endopds in male 1st pleopods,and shorter and thinner appendix masculina in male 2nd pleopods with only 1 spine on inner lateral margin and 4 spines in apex.The holotypes are deposited in Shanghai Fisheries University.Some representative paratypes are deposited in Foshan Science and Technology College.展开更多

The results show that Xuzhuang oilfield is infiltrated discontinuously by meteoric water under gravity, which consequently leads to the desalination of formation water. Formation water in the Zhenwu and Caozhuang oilfields is less influenced by meteoric water infiltration, and the origin is interpreted to be connate water. Hydrocarbon migration, accumulation and preservation are closely related to the hydrodynamic field of formation water. Formation water concentrates gradually during the process of centrifugal flow released by mudstone compaction and the centripetal flow of meteoric water infiltration, leading to the high salinity of the central part. The geological conditions of the southern fault-terrace belt are poor for hydrocarbon accumulation and preservation as meteoric water infiltration, leaching and oxidation, while the central part, i.e., northern Zhenwu and Caozhuang oilfields is beneficial for an abundance of hydrocarbon accumulation. Most of the large scale oil-~as fields locate herein.展开更多

In the paper, a quantitative model for the landslide hazard assessment and zoning was presented, in which the potential energy could be obtained on basis of thorough analysis of the potential sliding volume, distance and direction of the landslide body. Taking landslide potential energy as the index of the hazard severity zonation, the study area was divided into severe, heavy, medium and light hazard zones.展开更多
