The effect of shot peening (SP) on microstructure and hardness of ultrafine-grained (UFG) low-alloy steel was investigated. With increasing shot-peening time from 0.5 to 1.5 h, grain size of UFG low-alloy steel decreases from 400 to 280 nm at surface whilst that of the layer with a depth of 160μm decreases from (230 ± 15) to (75 ± 5) nm. Interestingly, nanoindentation shows that hardness increases linearly with increasing the SP duration, reaching a value as high as (7.10 ± 0.1) GPa at the depth of 160 μm after the SP duration of 1.5 h. The thickness of the SP treated layer is measured as^300 μm. The Hall-Petch (H-P) relationship was established for the hardening layer. Correspondingly, abrasion resistance should be ~51% higher than that of as-prepared UFG low-alloy steel. As shown in SP processing, grain refinement is the key factor responsible for the strengthening of the studied steel.

Metal speciation can provide sufficient infor- mation for environmental and geochemical researches. In this study, based on the speciation determination of Cu and Zn in the Yangtze Estuary sediments, roles of eight geochemical controls （i.e., total organic carbon （TOC）, clay, Fe/Mn in five chemical fractions and salinity） are fully investigated and sequenced with correlation analysis （CA） and principal components analysis （PCA）. Results show that TOC, clay and Fe/Mn oxides are key geochemical factors affecting the chemical speciation distributions of Cu and Zn in sediments, while the role of salinity appears to be more indirect effect. The influencing sequence generally follows the order： TOC 〉 clay 〉 Mn oxides 〉 Fe oxides 〉 salinity. Among the different fractions of Fe/Mn oxides, residual and total Fe content, and exchangeable and carbonate Mn exert the greatest influences, while exchangeable Fe and residual Mn show the poorest influences.

By examination of Calligonum pumilum A. Los. and Calligonum ruoqiangense Liou f.,collected from natural habitats,and the analysis of their variance,this paper revealed that the morphological characters of these specimens are quite different from each other,especially in the twist direction of ribs on fruits,rows of bristles along each rib,rigidity,interweaving degree of bristles,and their geographical distribution. Therefore,it is suggested that C. pumilum and C. ruoqiangense should be considered as two independent species.
