| 2 | Experimental study on scale inhibition performance of a green scale inhibitor polyaspartic acid显示文摘Static and dynamic experiments were carried out to validate scale inhibition performance of a green scale inhibitor-polyaspartic acid (PASP). From the static experiment, it was shown that below 60℃, polyaspartic acid is very effective in scale inhibition, with the scale inhibition ratio exceeding 90% with only 3 mg/L PASP for the 600 mg/L hardness solution. For a higher hardness solution of 800 mg/L, the scale inhibition ratio can also reach 90% with 6 and 12 mg/L PASP at 30 and 60℃respectively. The SEM photographs of CaCO3 crystals indicate that the crystal structure transforms from a compact stick-shape to a loose shape so that the scale can be washed away easily instead of being deposited on the heat transfer surface. The dynamic experimental results show that almost no scales formed on the heat trans- fer surface and the fouling thermal resistance decreases extraordinarily if PASP is added in the solution. | QUAN ZhenHua CHEN YongChang WANG XiuRong SHI Cheng LIU YunJie MA ChongFang | 2008 | Science China Chemistry2008，51，7： | 18 |
| 3 | Relationship between petroleum hydrocarbon and plankton in a mesocosm experiment显示文摘A mesocosm experiment was carried out from May 26 to June 1, 1998 at the location of 30’52’N, 122’36’E, the Changjiang Estuary, in order to measure the influence of petroleum hydrocar- bon to the ecosystem, furthermore, to estimate the environmental capacity. In the experiment, it is found that the petroleum hydrocarbon can, in some degree, enhance the growth of diatom, but inhibit the growth of dinoflagellate. In general, the petroleum hydrocarbon can inhibit the growth of both Phytoplankton and zooplankton, and can the inhibit the growth of total plankton (including phytoplankton and zooplankton) as well. A kinetic model was presented to estimate the uptake/release rate constants of petroleum hydrocarbon by plankton, and thereafter, the uptake and release rate constants (k1, k2), bioconcentration factor (BCF) as well as the petroleum bydrocarbon influenced influenced uptake and release rate constants of nutrients by phytoplankton (kup, krel) were obtained. The results imply that the bioconcentration of petroleum hydrocarbon by plankton is fairly large and petroleum hydrocarbon caused no significant influence on the uptake of N- NO3, but significant influence on that of P -PO4. In addition, the application of kinetic model for the bioconcentration of volatile organic toxic compound by organism suggests that the uptake of petroleum hydrocarbon by plankton was an important process for the environmental capacity of petroleum hydrocarbon. | Shi Xiaoyong, Wang Xiulin, Han Xiurong, Jiang Yu Zhu Mingyuan, Chen Shang, Koshikawa Hiroshi (1.

| 5 | An estimation of nutrient fluxes to the East China Sea continental shelf from the Taiwan Strait and Kuroshio subsurface waters in summer显示文摘According to historical mean ocean current data through the field observations of the Taiwan Ocean Research Institute during 1991–2005 and survey data of nutrients on the continental shelf of the East China Sea(ECS) in the summer of 2006, nutrient fluxes from the Taiwan Strait and Kuroshio subsurface waters are estimated using a grid interpolation method, which both are the sources of the Taiwan Warm Current. The nutrient fluxes of the two water masses are also compared. The results show that phosphate(PO4-P), silicate(SiO3-Si) and nitrate(NO3-N) fluxes to the ECS continental shelf from the Kuroshio upwelling water are slightly higher than those from the Taiwan Strait water in the summer of 2006. In contrast, owing to its lower velocity, the nutrient flux density(i.e., nutrient fluxes divided by the area of the specific section) of the Kuroshio subsurface water is lower than that of the Taiwan Strait water. In addition, the Taiwan Warm Current deep water, which is mainly constituted by the Kuroshio subsurface water, might directly reach the areas of high-frequency harmful alga blooms in the ECS. | LI Hongmei SHI Xiaoyong WANG Hao HAN Xiurong | 2014 | Acta Oceanologica Sinica2014，33，11： | 10 |

| 7 | Nutrient composition and distributions in coastal waters impacted by the Changjiang plume显示文摘Four cruises were conducted during 2002-2003 in the Changjiang Estuary and adjacent coastal areas. The data presented show a clear coast to open sea gradient in nutrients related to the river inputs. Maximum values of chlorophyll a were typically observed at intermediate salinities at surface water and coincided with non-conservative decreases in nutrients along the salinity gradient,indicating that removal of nutrients was related to phytoplankton uptake. The seasonal variations of nutrient concentrations were just opposite to those of chlorophyll a,indicating that the seasonal variations of nutrients were mainly controlled by phytoplankton uptake,whereas riverine inputs merely weakened or balanced its extent. During the estuarine mixing,phosphate demonstrated some remobilization during all the four cruises; whereas both conservative and non-conservative behaviors for dissolved inorganic nitrogen and silicate were observed in the study area,indicating that both biotic and abiotic events may affect their behaviors during the estuarine mixing. Under the influence of freshwater inputs with high value of ratio of nitrogen to phosphorus,the estuarine and coastal waters impacted by the Changjiang plume were high (>30) in ratio of nitrogen to phosphorus,but rates of primary production were apparently not constrained by any kind of nutrient elements. However,the low (<1) ratio of silicate to nitrogen in most of the study area might be linked with the rapidly increasing frequency of harmful algal bloom(HAB) incidents in recent years in the coastal waters impacted by the Changjiang plume. | WANG Xiulin WANG Baodong ZHANG Chuansong SHI Xiaoyong ZHU Chenjian XIE Linping HAN Xiurong XIN Yu WANG Jiangtao | 2008 | Acta Oceanologica Sinica2008，27，5： | 7 |
| 8 | Near-infrared reflectance spectroscopy reveals wide variation in major components of sesame seeds from Africa and Asia显示文摘Sesame is an important oilseed crop in Africa and Asia, owing to its high nutritional quality seed and market value. Variation in sesame seed components including oil, oleic acid,linoleic acid, and protein was investigated by near-infrared reflectance spectrometry in 139 samples collected from different countries. Oil and protein contents were between 40.8%and 60.3%(mean 53.0%) and 15.5% to 25.5%(mean 20.4%), respectively. Linoleic acid,ranging from 31.8% to 52.4%(mean 46%) was more abundant than oleic acid(31.8%–50.6%,mean 38.1%). Light-seeded samples displayed higher nutritional quality, as they were richer in oil, protein, and linoleic acid than dark seeds. Samples from Africa had higher oil and linoleic acid contents, while Asian samples had higher oleic content. The analysis revealed West African sesame cultivars containing especially high levels of seed components, which may command high market values. Two clusters of sesame samples grouped by seed composition were obtained, including one cluster with high oil and oleic acid content and the other with high protein and linoleic acid content. This study revealed that sesame samples from Africa and Asia harbor high variation for major seed components and also provided background information for breeding high-nutrition varieties according to the demands of sesame seed markets. | Komivi Dossa Xin Wei Marème Niang Pan Liu Yanxin Zhang Linhai Wang Boshou Liao Ndiaga Cissé Xiurong Zhang Diaga Diouf | 2018 | The Crop Journal2018，6，2： | 7 |
| 9 | Seasonal Changes in Phytoplankton Biomass and Dominant Species in the Changjiang River Estuary and Adjacent Seas:General Trends Based on Field Survey Data 1959-2009显示文摘The characteristics of seasonal variation in phytoplankton biomass and dominant species in the Changjiang River Estuary and adjacent seas were discussed based on field investigation data from 1959 to 2009. The field data from 1981 to 2004 showed that the Chlorophyll-a concentration in surface seawater was between 0.4 and 8.5 μg dm-3. The seasonal changes generally presented a bimodal trend, with the biomass peaks occurring in May and August, and Chlorophyll-a concentration was the lowest in winter. Seasonal biomass changes were mainly controlled by temperature and nutrient levels. From the end of autumn to the next early spring, phytoplankton biomass was mainly influenced by temperature, and in other seasons, nutrient level(including the nutrient supply from the terrestrial runoffs) was the major influence factor. Field investigation data from 1959 to 2009 demonstrated that diatoms were the main phytoplankton in this area, and Skeletonema costatum, Pseudo-nitzschia pungens, Coscinodiscus oculus-iridis, Thalassinoema nitzschioides, Paralia sulcata, Chaetoceros lorenzianus, Chaetoceros curvisetus, and Prorocentrum donghaiense Lu were common dominant species. The seasonal variations in major dominant phytoplankton species presented the following trends: 1) Skeletonema(mainly S. costatum) was dominant throughout the year; and 2) seasonal succession trends were Coscinodiscus(spring) →Chaetoceros(summer and autumn) → Coscinodiscus(winter). The annual dominance of S. costatum was attributed to its environmental eurytopicity and long standing time in surface waters. The seasonal succession of Coscinodiscus and Chaetoceros was associated with the seasonal variation in water stability and nutrient level in this area. On the other hand, long-term field data also indicated obvious interannual variation of phytoplankton biomass and community structure in the Changjiang River Estuary and adjacent seas: average annual phytoplankton biomass and dinoflagellate proportion both presented increased trends during the 1950 s-2000 s. | YANG Shu HAN Xiurong ZHANG Chuansong SUN Baiye WANG Xiulin SHI Xiaoyong | 2014 | Journal of Ocean University of China2014，13，6： | 7 |
| 10 | Application of Landscape Plants in the Huaxi National Urban Wetland Park显示文摘The current situation of plants in Shilihe Beach of the Huaxi National Urban Wetland Park was investigated and analyzed. The results show that there are about 181 species of landscape plants in this park, of which arbors and shrubs are dominant. Various species of plants grow differently because of different types of artificial maintenance. The overall partition of the wetland park dose not follow the features of a river-type wetland and is not clear. In this park, the planting area of hygrophyte is far less than that of terrestrial plants. As a result, the wetland park is evolving into a public garden. It is suggested that the overall design of the park should be conducted in accordance with site characteristics and resources, and the park should be developed and built reasonably based on the principle that the ecology is a priority. | WANG Jian WANG Xiurong SUN Su TAN Li LIU Hongyu | 2017 | Journal of Landscape Research2017，9，2： | 4 |
| 11 | Similar Ability of FbaA with M Protein to Elicit Protective Immunity Against Group A Streptococcus Challenge in Mice显示文摘Group A streptococcus(GAS),an important human pathogen,can cause various kinds of infections including superficial infections and potentially lethal infections,and the search for an effective vaccine to prevent GAS infections has been ongoing for many years. This paper compares the immunogenicity and immunoprotection of FbaA(an Fn-binding protein expressed on the surface of GAS) with that of M protein,the best immunogen of GAS. Assay for immune response showed that FbaA,similar to M protein,could induce protein-specific high IgG titer in BALB/c mice. Furthermore,following GAS challenge,the mice immunized with FbaA showed the same protective rate as those with M protein. These results indicate that FbaA is similar in ability to M protein in inducing protective immunity against GAS challenge in mice. | Cuiqing Ma Caihong Li Xiurong Wang Ruihong Zeng Xiaolin Yin Huidong Feng Lin Wei | 2009 | Cellular & Molecular Immunology2009，6，1： | 4 |
| 12 | Analysis of the Transformation-induced Plasticity Effect during the Dynamic Deformation of High-manganese Steel显示文摘The transformation-induced plasticity(TRIP) effect and resistance characteristics to adiabatic shear failure at high strain rates of high-manganese steel were investigated by using scanning electron microscopy and electron backscattering diffraction. Results showed that the high-manganese steel exhibited excellent strain hardening effect and resistance to adiabatic shear failure because of the TRIP effect. The TRIP effect occurred during dynamic deformation and showed two distinct stages,namely,the smooth TRIP process before the formation of adiabatic shear band(ASB) and the inhibited TRIP process during further deformation. In the first stage,the martensitic transformation showed slight orientation dependence and weak variant selection,which promoted the TRIP effect. In the second stage,reverse martensitic transformation occurred. Adiabatic shear bands(ASBs) developed typical shear microtextures {111}<110>. In microtextures,two groups of fine grains are in a twin relationship and uniform distribution,which restrained the formation of holes and cracks within the ASBs and enhanced damage resistance after ASB formation. | Huizhen Wang Xiurong Sun Ping Yang Weimin Mao Li Meng | 2015 | Journal of Materials Science & Technology2015，31，2： | 4 |

| 15 | Hot deformation behavior and microstructure evolution of the laser solid formed TC4 titanium alloy显示文摘Hot compressive experiments of the laser solid formed(LSFed)TC4 titanium alloy were conducted at a wide temperature range of 650-950℃and strain rate of 0.01-10 s^(-1).The Arrheniustype constitutive models of the LSFed TC4 alloy were established at the temperature range of 800-950℃and of 650-800℃,respectively.The average relative error between the predicted stresses and experimental values in those two temperature ranges are 10.4%and 8.3%,respectively,indicating that the prediction models constructed in this paper are in a good agreement with experimental data.Processing maps were established by the principle of dynamic materials modeling on the basis of the data achieved from the hot compression experiments.The processing parameters corresponding to the stable and unstable regions of material deformation can be determined from the processing maps.The microstructure evolution of the stable and unstable regions of the samples after tests were observed.Finally,the effect of hot compressive parameters on the microstructure were investigated to research the dynamic recrystallization and the texture of the deformed LSFed TC4 alloy. | Xiawei YANG Yanying WANG Xiurong DONG Chong PENG Baijin JI Yaxin XU Wenya LI | 2021 | Chinese Journal of Aeronautics2021，34，5： | 3 |

| 17 | Effect of impregnation methods on sorbents made from lignite for desulfurization at middle temperature显示文摘With lignite after vacuum drying as the raw material,a series of Zn-based sorbents were prepared by static impregnation,ultrasonic-assisted impregnation,bubbling-assisted impregnation and high-pressure impregnation.The physical properties and the desulfurization performances of Zn-based sorbents were studied systematically by XRD,BET,AAS characterization techniques and the fixed-bed desulfurization evaluation apparatus.The sorbents obtained by high-pressure impregnation method have a larger specific surface area,pore volume and pore diameter comparing with other methods,which is conducive to the sulfidation reaction of hydrogen sulfide gas in the sorbent.The effects of pressure during the high-pressure impregnation and concentration of Zn(NO3)2 precursor solution on the sorbents properties and desulfurization behavior were investigated.The higher the impregnation pressure and the concentration of impregnation solution are,the greater the amount of the active components are uploaded.However,overhigh impregnation pressure can cause collapse and blocking of the carrier pore.The optimal operating condition of high-pressure impregnation method for preparing the sorbents was the impregnation pressure of 20 atm and the solution concentration of 41%.Under that condition,the sorbent had the best desulfurization ability with a sulfur capacity of 13.94 gS/100 gsorbent and a breakthrough time of 54 h.Its desulfurization precision and efficiency of removing H2S before sorbent breakthrough from the middle temperature gases of 400℃ can reach<5 ppm and>99%,respectively.Sorbents could be regenerated under the condition of 1 vol%O2,20 vol% H2O,0.5 vol% NH3,and N2balance gas.The regenerated sorbent could be used for repeated absorption of H2S with a slight decrease in desulfurization effect. | Yurong Dong Xiurong Ren Meijun Wang Qiang He Liping Chang Weiren Bao | 2013 | Journal of Energy Chemistry2013，22，5： | 3 |
| 18 | Modelling Nitrogen and Phosphorus Dynamics in a Mesocosm Pelagic Ecosystem in Laizhou Bay in China显示文摘A model of nitrogen and phosphorus dynamics in mesocosm experiments was established on the basis of a summary and synthesis of the existing models. The established model comprised seven state variables(DIN,PO4-P,DON,DOP,phytoplankton,zooplankton and detritus) and five modules - phytoplankton,zooplankton,dissolved inorganic nutrients,dissolved organic nutrients and detritus. Comparison with the in situ experimental data in Laizhou Bay at the end of August 2002 showed that this model could properly simulate the variations of DIN,PO4-P,and phytoplankton biomass in a mesocosm pelagic ecosystem. It was found that not only the model structure but also the parameters adopted were fit for simulation. The sensitivity of the main state variables to the parameter change was assessed by sensitivity analysis. All these results are useful for studying the control mechanism of biogeochemical cycling of nutrients in Laizhou Bay and other Chinese coastal waters. | LI Keqiang WANG Xiulin HAN Xiurong SHI Xiaoyong CHEN Hu | 2009 | Journal of Ocean University of China2009，8，2： | 3 |
| 19 | Isolation and application of effective nitrogen fixation rhizobial strains on low-phosphorus acid soils in South China显示文摘Soybean (Glycine max L.) is a very important food and oil crop in China. Legume-rhizobium symbiotic nitrogen (N) fixation is an important biological character and also the base of improving soil fertility of soybean. However, soybean production and development is severely limited in tropical and subtropical areas in China due to a lack of effective rhizobial inoculants adapting to low-phosphorus (P) acid soils. In the present study, 12 soybean rhizobial strains were isolated and purified from the nodules of two soybean genotypes contrasting in P efficiency, which were grown on different low-P acid soils with different soybean cultivation histories. Results from 16S rDNA sequence analysis showed that these 12 rhizobial strains belonged to the genus of Bradyrhizobium, which had higher nitrogenase activities compared to the control strain, Bradyrhizboium japonicum USDA110. A field experiment was carried out by applying rhizobial inoculants, a mixture of three rhizobial strains that showed the highest ni- trogenase activity, on a typical low-P acid soil in South China. The results showed that, without inocu- lation, no nodules were formed in the three soybean genotypes tested; with inoculation, the nodulation rates in all were 100%. Inoculation with rhizobial inoculants not only made many nodules formed, but also increased soybean shoot biomass and yield, and improved nitrogen (N) and P nutrient status. Among which, shoot dry weight, N and P content of a soybean genotype, Huachun 3, inoculated with rhizobium were increased 154.3%, 152.4% and 163.2% compared to that without inoculation, respec- tively. We concluded that: (i) The effective indigenous rhizobial strains isolated in this study from soybeans on low-P acid soils in South China have the characters of broad host range, high nodulation efficiency, efficient N fixation, great low pH and low P tolerance. (ii) Soil environment and host types are the key factors to screen the effective rhizobial strains. Considering soil pH values and P efficiency of the host genotypes might increase the screening efficiency. (iii) Improving N status and facilitating root growth might be the mechanisms of increasing the P uptake in soybean plants inoculated with the ef- fective rhizobial strains on low-P acid soils. (iv) Inoculation with the effective rhizobial inoculants could significantly improve growth, N and P content of soybean on low-P acid soils, which might be an effec- tive approach to enhance soybean cultivation and development in these areas. Therefore, application and extension of inoculation techniques with effective rhizobial inoculants in legumes would result in great economical, environmental and ecological benefits. | CHENG FengXiant CAO GuiQin WANG XiuRong ZHAO Jing YAN XiaoLong LIAO Hong | 2009 | Chinese Science Bulletin2009，54，3： | 3 |
| 20 | In vitro induction of mouse meningeal-derived iPS cells into neural-like cells显示文摘Previous research has shown that mouse embryonic stem (ES) cells can be induced to form neural cells in adherent monocultures.In this study,pluripotent stem (iPS) C5 cells derived from meningeal membranes were converted successfully into neural-like cells using the same protocol generally used for ES cells.Meningeal-iPS C5 cells were induced to express neural markers Sox1,Sox3,Pax6,Nestin and Tuj1 and to reduce the expression of ES markers Oct4 and Nanog during neural differentiation,and can be differentiated into Pax6 and Nestin positive neural progenitors,and further into neuronal,astrocytic,and oligodendrocytic cells.In vitro differentiation of iPS cells into patient-specific neural cells could serve as a model to study mechanisms of genetic diseases and develop promising candidates for therapeutic applications in dysfunctional or aging neural tissues.Meningeal cells express a high level of the embryonic master regulator Sox2,allowing them to be reprogrammed into iPS cells more easily than other somatic cells. | XU Jing WANG Hao LIANG Tao CAI XiangSheng RAO XiuRong HUANG ZhenBo SHENG GuoQing | 2011 | Chinese Science Bulletin2011，56，15： | 2 |
