| 2 | Identification of the lower limit of high-quality source rocks and its relation to hydrocarbon accumulation——Taking the Beier Sag in the Hailaer Basin as an example显示文摘The theory of 'source rock control' has evolved from source-rock-control hydrocarbon accumulation, to effective source-rock-control hydrocarbon accumulation, and to high-quality source-rock-control hydrocarbon accumulation. However, there are problems, such as whether high-quality source rocks exist or not? What high-quality source rocks are, and how to identify them, are yet to be agreed upon. Aimed at this issue of concern to explorationists, and taking the Beier Sag in the Hailaer Basin as an example, this paper defines the high-quality source rocks and the lower limit for evaluation of high-quality source rocks, by using the inflection point on the relationship curve of hydrocarbon (oil) expulsion, which is calculated by the material balance principle, versus total organic carbon (TOC). The results show that when TOC is low, all source rocks have limited hydrocarbon expulsion and slow growth rate, thus they cannot be high-quality source rocks. However, when TOC rises to some threshold, hydrocarbon expulsion increases significantly with TOC. This inflection point should be the lower limit of high-quality source rocks: those with TOC greater than the inflection-point value are high-quality source rocks. In addition, the lower limit of high-quality source rocks is also related to the type and maturity of organic matters in the source rocks, as well as the mineral components of the source rocks affecting the residual hydrocarbons. Theoretically, the lower limit of high-quality source rocks depends on geological conditions rather than being a constant value. However, for the sake of simplicity and practicability, in this paper TOC=2.0% is regarded as the lower limit of high-quality source rocks. The examination of such standard in the work area indicates that the high-quality source rocks in members K 1 n 2 and K 1 n 1 of the Nantun formation contribute 76% and 82% to oil generation, and 96% and 91% to oil expulsion , respectively. The distribution of high-quality source rocks is also closely related to the distribution of hydrocarbon reservoirs in the region, demonstrating that high-quality source rocks control hydrocarbon accumulation. | Lu Shuangfang Chen Fangwen Li Jijun Wang Weiming Li Huiguang Cao Ruicheng Ma Yanling | 2012 | Petroleum Science2012，9，1： | 7 |
| 3 | Effects of key design parameters of tine furrow opener on soil seedbed properties显示文摘The structural parameters of tine furrow openers have significant effects on soil property of seed furrow in no-till planting,thereby affecting crop growth and yields.In order to analyze the effects of key parameters of tine furrow openers on soil properties(soil bulk density,soil water-stable aggregates(WSA),and soil disturbance)of the surface soil layer of 0-10 cm and surface straw disturbance,the tine furrow openers with different structural parameters,including cutting edge thickness,cutting edge curve,penetration clearance angle and rake angle,were designed and tested under no-till conditions.Orthogonal test and single factor test were performed to analyze the effects of different parameters.Results showed that the rake angle,cutting edge thickness and cutting edge curve had significant effects on cross-sectional area of furrow(Af)and disturbance of surface straw;the rake angle had a significant effect on soil bulk density.Soil types and operating depth had significant effects on soil disturbance caused by tine furrow openers.The concave type tine furrow opener produced the lowest soil disturbance and soil bulk density of seed furrow,the highest surface straw disturbance and the greatest content of WSA(>0.5 mm).With increasing rake angles of tine furrow opener,the width of seedbed(Wsb)and the Af decreased first and then increased,respectively,while the width of soil throw(Wst)and the height of ridge(Hr)increased.The Wsb and Af created by tine furrow opener with 60°rake angle were significantly lower than that with others,respectively.The tine furrow opener with rake angle ranged from 45°to 60°created the lowest soil bulk density.As the penetration clearance angle increased,the content of WSA(>0.5 mm)decreased,but the effect of penetration clearance angle on the content of WSA(<0.5 mm)was not significant.The cutting edge thickness(<2 mm)had no significant effects on soil properties of seedbed.This study could provide a reference for optimal design of the tine furrow opener to create more suitable seedbed environment,and promote the application of the light no-till planters. | Zhang Xiangcai Li Hongwen Du Ruicheng Ma Shaochun He Jin Wang Qingjie Chen Wanzhi Zheng Zhiqi Zhang Zhiqiang | 2016 | International Journal of Agricultural and Biological Engineering2016，9，3： | 7 |
| 4 | Critical review of perovskites-based advanced oxidation processes for wastewater treatment: Operational parameters, reaction mechanisms,and prospects显示文摘In the field of advanced oxidation processes(AOPs) of wastewater, many materials can be used as heterogeneous catalysts. The role of these catalysts is to activate oxidants and generate reactive oxygen species(ROS) to decompose refractory pollutants. Perovskite oxide, an emerging catalyst in the field of AOPs, has been extensively studied in wastewater treatment. Nevertheless, the application of perovskite in AOP systems still faces some problems, such as leaching of metal ions, a small surface area, a low number of active sites, etc. Herein, this critical review comparatively examines the activation mechanisms of peroxymonosulfate, hydrogen peroxide, and peroxydisulfate. Furthermore, the formation pathways of oxidizing species based on recent advances in experimental and theoretical studies were evaluated. In addition, the impacts of water parameters and constituents such as initial p H, oxidant concentration, catalyst dosage,natural organic matter, halide, phosphate, and carbonate were discussed. Finally, a critical discussion and prospects of mechanism exploration and possible materials development are proposed to confront the existing challenges in the application of perovskite oxides in AOPs. | Ruicheng Ji Jiabin Chen Tongcai Liu Xuefei Zhou Yalei Zhang | 2022 | Chinese Chemical Letters2022，33，2： | 4 |
| 5 | Crack propagation mechanism of γ-TiAl alloy with pre-existing twin boundary显示文摘The deformation and failure mechanisms of γ-TiAl alloy with pre-existing crack and twin boundary are investigated by using molecular dynamics simulation. The effects of the crack position on the deformation and failure mechanisms of γ-TiAl specimen are analysed through the snapshots of crack propagation, microstructure of crack tip and stress-strain curves. The simulation results show that the dislocation motion is impeded, the good ductility can be maintained and the strength would be improved simultaneously by the twin boundary. The microstructure evolution of crack tip would change with crack positions. Essentially,the deformation behaviour mainly results from the reaction of dislocation-dislocation, dislocation-twin and twin-twin. Besides,the hierarchical twin is a main plastic deformation mechanism leading to strength of γ-TiAl specimen enhancement with noncompromising ductility and strain hardening. Based on stress-strain curves, it can be concluded that the yield strength varies with crack positions. They are the determinant factors for variation of the yield strength with different crack positions such as dislocation behaviour, stacking fault and hierarchical twin. The ductile-brittle transition associated with the dislocation motion and the decohesion failure of crack tip atom can be observed from the lower boundary crack and the center crack models. The crack propagation caused by the coalescent of the void and the crack tip is the main failure mechanism of γ-TiAl specimen. In addition, the results reveal that the mechanism of crack propagation would be influenced by pre-existing twin boundary which can prevent the crack propagation and improve the fracture toughness. | CAO Hui RUI ZhiYuan CHEN WenKe FENG RuiCheng YAN ChangFeng | 2019 | Science China(Technological Sciences)2019，62，9： | 2 |

| 15 | Mechanism of ball milled activated carbon in improving the desalination performance of flow-and fixed-electrode in capacitive deionization desalination显示文摘Capacitive deionization(CDI)is a novel electrochemical water-treatment technology.The electrode material is an important factor in determining the ion separation efficiency.Activated carbon(AC)is extensively used as an electrode material;however,there are still many deficiencies in commercial AC.We adopted a simple processing method,ball milling,to produce ball milled AC(BAC)to improve the physical and electrochemical properties of the original AC and desalination efficiency.The BAC was characterized in detail and used for membrane capacitive deionization(MCDI)and flow-electrode capacitive deionization(FCDI)electrode materials.After ball milling,the BAC obtained excellent pore structures and favorable surfaces for ion adsorption,which reduced electron transfer resistance and ion migration resistance in the electrodes.The optimal ball-milling time was 10 h.However,the improved effects of BAC as fixed electrodes and flow electrodes are different and the related mechanisms are discussed in detail.The average salt adsorption rates(ASAR)of FCDI and MCDI were improved by 134%and 17%,respectively,and the energy-normalized removal salt(ENRS)were enhanced by 21%and 53%,respectively.We believe that simple,low-cost,and environmentally friendly BAC has great potential for practical engineering applications of FCDI and MCDI. | Ge Shen Junjun Ma Jianrui Niu Ruina Zhang Jing Zhang Xiaoju Wang Jie Liu Jiarong Gu Ruicheng Chen Xiqing Li Chun Liu | 2023 | Frontiers of Environmental Science & Engineering2023，17，5： | 0 |
