| 1 | 加氧灌溉对菠萝根区土壤呼吸和生理特性的影响显示文摘通过大田试验,研究了加氧灌溉对菠萝根区土壤呼吸作用、生理特性、生物量积累、果实产量、品质和水分利用效率的影响.采用Mazeei(空气注射器)给地下灌溉系统加入空气,设计了加氧和不加氧灌溉2种处理方式,7次重复.设计滴头埋深10 cm.研究表明,与对照相比,菠萝根区30 cm以内土壤水分质量分数和CO2质量分数没有明显差异,但是加氧灌溉使得土壤呼吸增加了100%;菠萝的果实鲜重、生物量鲜重、干物质重和收获指数明显增大,差异有统计学意义(p≤0.05);加氧灌溉提高了菠萝的水分生产率,与对照相比增加了17.2%;同时,加氧灌溉明显改善了菠萝单果尺寸和重量,使得单果重量增加了17.3%,田间产量增加了4.3%,增加了果实的糖质量分数,减少了果实的透明物.研究结果为加氧灌溉技术的推广应用提供了理论依据. | 陈新明 Jay Dhungel Surya Bhattarai Manouchehr Tobrabi Dayid J Midmore | 2010 | 排灌机械工程学报2010,28,6: | 43 |
| 2 | Impact of oxygation on soil respiration, yield and water use efficiency of three crop species显示文摘Oxygation refers to irrigation of crops with aerated water,through air injection using the venturi principle or the supply of hydrogen peroxide in the root zone,both using subsurface drip irrigation(SDI)system.Oxygation improves water use efficiency(WUE),producing more yield and,and therefore,optimizes the use of drip and SDI.But the efficiency of oxygation is quite possibly dependent on a number of factors.The primary objective of this study was,therefore,to quantify the effects of oxygation,emitter depths and soil type on crop root zone oxygen content,soil respiration,plant physiological response,biomass yield,quality and WUE of three crop species.Methods This study investigated the potential of oxygation to enhance soil respiration,plant growth,yield and water use efficiencies(WUE)of cotton and wheat in experiments in enclosed heavy-duty concrete troughs(tubs)and pineapple and cotton in field experiments.Experimental treatments in tubs for wheat included comparisons between two soil types(vertisol and ferrosol)and superimposed were two oxygation methods(Mazzei air injector and Seair Diffusion System)compared to a control,and for cotton,emitters at two depths using Mazzei air injectors were compared to a control.The field experiments compared Mazzei air injectors and a control for cotton in Emerald and pineapple in Yeppoon,both in central Queensland,Australia.Important findings In all experiments,soil oxygen content and soil respiration markedly increased in response to the oxygation treatments.The O2 concentration in the crop root zone increased by 2.4–32.6%,for oxygation compared to control at the same depth.The soil respiration increased by 42–100%.The number of wheat ears,leaf dry weight and total dry matter were significantly greater in Mazzei and Seair oxygation compared to the control.Fresh biomass of wheat increased by 11 and 8%,and dry weight of wheat increased by 8 and 3%in Mazzei and Seair oxygation treatments compared to the control,respectively.Likewise,the irrigation water use efficiency increased with oxygation compared to the control in wheat.The yield,WUE and number of other physiological parameters in wheat were enhanced in vertisol compared to ferrosol.The seed cotton yield in the tub experiment increased with oxygation by 14%,and significant differences for fresh biomass,dry matter and yield were also noted between oxygation and the control in the field.Lint yield and WUE both increased by 7%using Mazzei in the cotton field trial during 2008–09.There were significant effects of oxygation on pineapple fresh biomass,and dry matter weight,industry yield and a number of quality parameters were significantly improved.The total fruit yield and marketable increased by 17 and 4%and marketable WUE increased by 3%using Mazzei.Our data suggest that the benefits of oxygation are notable not only for dicotyledonous cotton but also for monocotyledonous wheat and pineapple representing different rooting morphologies and CO_(2) fixation pathways. | Xinming Chen Jay Dhungel Surya P.Bhattarai Manouchehr Torabi Lance Pendergast David J.Midmore | 2011 | Journal of Plant Ecology2011,4,4: | 46 |
| 3 | 页岩气产量数据分析方法及产能预测显示文摘基于页岩气井线性非稳态流动特点,运用双重孔隙线性瞬态流典型曲线分析Eagle Ford页岩气藏一口多级压裂水平井产量数据,并进行储量评价。根据产量与时间双对数曲线关系,将该气井生产分为表皮效应、线性流动、边界效应3个流动阶段;运用基质线性流动模型计算该气藏基质渗透率,利用数值模型对计算结果进行验证;根据边界效应时间点求取该井体积压裂范围游离气储量,在此基础上进行产能预测,并研究吸附气解吸对气井产量的影响。结果表明:该井体积压裂范围游离气储量与裂缝模拟结果符合度超过85%;解吸气对页岩气井产量贡献取决于平均地层压力与吸附曲线形态;解吸气对该页岩气藏开发早中期的影响可忽略,对开发后期产量的影响很大,气体解吸能增加总采出量30%以上。 | 徐兵祥 李相方 HAGHIGHI Manouchehr 张磊 张保瑞 王威 | 2013 | 中国石油大学学报(自然科学版)2013,37,3: | 37 |
| 4 | 裂缝性页岩气藏水平井产能预测模型显示文摘基于页岩气藏线性、非稳态流动特点,考虑未压裂区双重介质特点及其对产气的贡献,建立页岩气多级压裂水平井渗流模型并求得定压条件下Laplace空间解。数值模型验证表明解析解与数值解吻合度高,在此基础上推导新的页岩气双孔瞬态产量典型曲线,补充和发展原有页岩气SRV模型典型曲线,并进行参数敏感分析,将新建典型曲线与SRV模型、Brohi模型典型曲线进行对比。结果表明:新典型曲线流动阶段表现为线性流与过渡流交替,较Brohi单孔外区模型典型曲线更复杂;气藏尺寸、窜流系数、内外区裂缝渗透率比对典型曲线影响很大,而储容比的影响不明显;未压裂区天然裂缝对气井产量有积极作用,对页岩气藏进行产能预测时不可忽略。 | 徐兵祥 李相方 HAGHIGHI Manouchehr 张磊 龚崛 葛涛涛 | 2013 | 中国石油大学学报(自然科学版)2013,37,6: | 14 |
| 5 | Reduction of local scour around bridge pier groups using collars显示文摘In this paper reduction of scour around group of two and three piers using circular collar has been carried out for the case of clear-water flow over uniform sediment. The efficiency of collars, with different sizes and spaces between piers is studied through experiments in group of two and three piers. The result reveals that collar has more influence in reduction of scour depth in rear piers than the first pier. Also, when the spacing between the piers increases the area without protection between the piers is washed away resulting deeper scour holes at the rear piers. | Manouchehr HEIDARPOUR Hossein AFZALIMEHR Elham IZADINIA | 2010 | International Journal of Sediment Research2010,25,4: | 8 |
| 6 | Application of Rice Husk Biochar for Achieving Sustainable Agriculture and Environment显示文摘This paper critically reviewed the current knowledge and challenges of rice husk biochar(RHB)production and its effects on soil properties,plant growth,immobilization of heavy metals,reduction of nutrient leaching and mitigation of greenhouse gas emissions.The characteristics of RHBs produced at various pyrolysis temperatures were discussed and compared to biochars derived from other agro-industrial wastes.RHBs produced at higher pyrolysis temperatures show lower hydrogen/carbon ratio,which suggests the presence of higher aromatic carbon compounds.The increase of pyrolysis temperature also results in production of RHBs with higher ash content,lower yield and higher surface area.RHB usually has higher silicon and ash contents and lower carbon content compared to biochars derived from other feedstocks at the same pyrolysis conditions.Although it depends on soil type,RHB application can improve soil organic carbon content,cation exchange capacity,available K concentration,bulk density and microbial activity.The effect of RHB on soil aggregation mainly depends on soil texture.The growth of different crops is also enhanced by application of RHB.RHB addition to soil can immobilize heavy metals and herbicides and reduce their bioavailability.RHB application shows a significant capacity in reduction of nitrate leaching,although its magnitude depends on the biochar application rate and soil biogeochemical characteristics.Use of RHB,especially in paddy fields,shows a promising mitigation effect on greenhouse gas(CH4,CO2 and N2O)emissions.Although RHB characteristics are also related to other factors such as pyrolysis heating rate and residence time,its performance for specific applications(e.g.carbon sequestration,pH amendment)can be manipulated by adjusting the pyrolysis temperature.More research is needed on long-term field applications of RHB to fully understand the advantages and disadvantages of RHB as a soil amendment. | Hossein Asadi Mohammad Ghorbani Mehran Rezaei-Rashti Sepideh Abrishamkesh Elnaz Amirahmadi Chen Chengrong Manouchehr Gorji | 2021 | Rice science2021,28,4: | 4 |

| 8 | Fluidized bed coating efficiency and morphology of coatings for producing Al-based nanocomposite hollow spheres显示文摘We performed fluidized bed coating of Al-based nanocomposite powder–binder suspensions onto polymer substrates. The effects of the type and amount of the binder and nanoparticle additive on the coating process efficiency and coating characteristics were investigated. The efficiency decreased from 52% to 49% as the processing time increased from 15 to 20 min. However, the amount and thickness of the coating also increased as the processing time and amount of the binder were increased. The addition of nanoparticles to the system decreased the thickness of the coating from 222 to 207 μm when polyvinyl alcohol(PVA) was used as a binder. The suspension containing 3wt% R-4410 binder exhibited the greatest efficiency of 60%. | Mostafa Amirjan Hamid Khorsand Manouchehr Khorasani | 2014 | International Journal of Minerals,Metallurgy and Materials2014,21,11: | 3 |

| 11 | The Use of Fractal for Prediction of Burning Rate of Composite Solid Propellants显示文摘By using the fractal geometry it is possible to calculate the actual AP (Ammonium Perchlorate) surface area and oxidizer-binder interface fractal dimension in the prediction of burning rate of composite solid propellants. In this investigation, the fractal dimension was determined by a procedure known as the 'Box Counting Method'. Using this dimension, surface area relations were developed for the rough particles. This method was implemented in the PEM (Petite Ensemble Model) burning rate model. The comparison of burning rates for a typical propellant by the PEM and fractal model shows that the burning rates obtained by using the fractal geometry are slightly less than those obtained by the PEM model. | Manouchehr Nikazar,Mohammad B.
