| 1 | 中温和高温环境下乙酸和丙酸厌氧发酵产甲烷动力学特征显示文摘采用不同浓度的乙酸和丙酸在中高温下进行厌氧发酵批次试验,采用修正的Gompertz模型和产甲烷的一级动力学模型分析,研究酸浓度和温度对发酵产气动力学的影响。研究表明,当乙酸和丙酸浓度较低时降解较快,高浓度酸抑制产气。乙酸在中温条件下降解较快,质量浓度为5 000 mg/L时中温反应有最大产甲烷速率101 mL/d;质量浓度为10 000mg/L时高温条件下有最大产甲烷速率77mL/d,随酸浓度增加,最大产甲烷速率减小,高温反应器对酸的耐受度较高。丙酸在高温条件下更易降解,浓度为4 000 mg/L时,中高温反应均有最大产气速率:78 mL/d(中温)和96 mL/d(高温)。另外,高浓度乙酸和丙酸厌氧降解产气具有滞后性,且随酸浓度的增加滞后期延长,降解过程受到抑制,一级动力学常数减小。温度对厌氧降解的影响大于酸浓度对厌氧降解的影响。 | 乔玮 姜萌萌 赵婧 Wandera S.M 董仁杰 | 2018 | 农业工程学报2018，34，21： | 9 |
| 2 | Estimation of Hourly and Daily Global Solar Radiation at Clear Days Using an Approach Based on Modified Version of Gaussian Distribution显示文摘The performance of two models,Jam and Baig,based on the modified version of Gaussian distribution function in estimating the daily total of global solar radiation and its distribution through the hours of the day from sunrise to sunset al any clear day is evaluated with our own measured data in the period from June 1992 to May 1993 in Qena Egypt The results show a high relative deviation of calculated values from measured ones,especially for Jain model,in the most hours of the day,except for those near to local noon.This misfit behavior is quite obvious in the early morning and late afternoon A new approach has been proposed in this paper to estimate the daily and hourly global solar radiation This model performs with very high accuracy on the recorded data in our region.The validity of this approach was verified with new measurements in some clear days in June and August 1994.The resultant very low relative deviation of the calculated values of global solar radiation from the measured ones confirms | S.M EI shazly | 1996 | Advances in Atmospheric Sciences1996，13，3： | 4 |

| 7 | Dynamic Analysis of Non-Symmetric Functionally Graded (FG) Cylindrical Structure under Shock Loading by Radial Shape Function Using Meshless Local Petrov-Galerkin (MLPG) Method with Nonlinear Grading Patterns显示文摘In this paper,dynamic behavior of non-symmetric Functionally Graded(FG)cylindrical structure under shock loading is carried out.Dynamic equations in the polar coordinates are drawn out using Meshless Local Petrov-Galerkin(MLPG)method.Nonlinear volume fractions are used for radial direction to simulate the mechanical properties of Functionally Graded Material(FGM).To solve dynamic equations of nonsymmetric FG cylindrical structure in the time domain,the MLPG method are combined with the Laplace transform method.For computing the inverse Laplace transform in the present paper,the Talbot algorithm for the numerical inversion is used.To verify the obtained results by the MLPG method,these results are compared with the analytical solution and the Finite Element Method(FEM).The obtained results through the MLPG method show a good agreement in comparison to other results and the MLPG method has high accuracy for dynamic analysis of non-symmetric FG cylindrical structure.The capability of the present method to dynamic analysis of non-symmetric FG cylindrical structure is demonstrated by dynamic analysis of the cylinder with different volume fraction exponents under harmonic and rectangular shock loading.The present method shows high accuracy,efficiency and capability to dynamic analysis of non-symmetric FG cylindrical structure with nonlinear grading patterns,which furnishes a ground for a more flexible design. | Y.Sadeghi Ferezghi M.R.Sohrabi S.M Mosavi Nezhad | 2017 | Computer Modeling in Engineering & Sciences2017，，4： | 2 |
