| 1 | Statistical approach to determination of overhaul and maintenance cost of loading equipment in surface mining显示文摘The purpose of this research was to develop a new approach in determination of overhaul and maintenance cost of loading equipment in surface mining. Two statistical models including univariate exponential regression (UER) and multivariate linear regression (MLR) were used in this study. Loading equipment parameters such as bucket capacity, machine weight, engine power, boom length, digging depth, and dumping height were considered as variables. The results obtained by models and mean absolute error rate indicate that these models can be applied as the useful tool in determination of overhaul and maintenance cost of loading equipment. The results of this study can be used by the decision-makers for the specific surface mining operations. | Lashgari Ali Sayadi Ahmad Reza | 2013 | International Journal of Mining Science and Technology2013，23，3： | 8 |
| 2 | 中孔氧化硅负载铬催化剂上苯高选择性生成苯酚:响应曲面分析法用于反应条件优化(英文)显示文摘以硝酸铬为前驱体,中孔氧化硅SBA-16为载体,采用简单浸渍法制备了Cr/SBA-16催化剂,并采用广角和小角X射线衍射、N2吸附-脱附、透射电镜和紫外-可见光谱等技术对其进行了表征.同时将该催化剂用于以H2O2为氧化剂的苯直接羟基化制苯酚反应以考察其催化性能.将中心组合设计与响应曲面分析法(RSM)相结合,对影响反应性能的操作变量如反应温度、反应时间及HO2和催化剂用量进行了优化.结果表明,独立变量和苯酚产率之间的关系可用二阶多项式模型来表达,其相关系数(R22)高达0.985,表明用RSM预测的数值与实验值吻合较好.得到的苯酚选择性较高时的操作条件为:反应温度324 K,反应时间8 h,H2O2和催化剂用量分别为3.28 mL和0.09 g.由此可见,将RSM法用于苯羟基化制苯酚反应条件优化是可靠的. | Milad Jourshabani Alireza Badiei Negar Lashgari Ghodsi Mohammadi Ziarani | 2015 | Chinese Journal of Catalysis2015，36，11： | 3 |
| 3 | 氨基功能化的介孔SBA-15分子筛在一锅法合成螺羟吲哚中的应用(英文)显示文摘Amino-functionalized SBA-15(SBA-Pr-NH2) has been used as a new basic nanocatalyst in the one-pot synthesis of spirooxindole derivatives via the three-component condensation reaction of isatins,activated methylene reagents,and dimedone in an aqueous medium.SBA-Pr-NH2 has been established as an efficient heterogeneous nanoporous solid basic catalyst(pore size of 6 nm) that can be easily handled and removed from the reaction mixture by simple filtration,and also recovered and reused without noticeable loss of reactivity. | Ghodsi MOHAMMADI ZIARANI Alireza BADIEI Somayeh MOUSAVI Negar LASHGARI Afsaneh SHAHBAZI | 2012 | 催化学报2012，33，11： | 2 |
