1非农收入对于水稻生产技术效率的影响及启示显示文摘本文采用随机前沿生产函数,利用斯里兰卡农户大样本调研数据,分析非农收入对水稻生产技术效率的影响。结果表明,非农收入对于水稻生产技术效率的影响是非线性的,呈现倒U型,这说明非农收入对于农业技术效率的影响是个动态过程,而前期相关研究仅仅捕捉了该变化过程某个阶段。研究结果对于正确认识城镇化和非农就业对中国水稻生产系统的影响及其政策都提供了重要参考。王怀豫 董婉璐 VELARDE Orlee REJESUS Roderick 杨军 2019山东农业大学学报(社会科学版)2019,21,1:2
2Formulation development and characterization of cellulose acetate nitrate based propellants for improved insensitive munitions properties显示文摘Cellulose acetate nitrate(CAN) was used as an insensitive energetic binder to improve the insensitive munitions(IM) properties of gun propellants to replace the M1 propellant used in 105 mm artillery charges.CAN contains the energetic nitro groups found in nitrocellulose(NC),but also acetyl functionalities,which lowered the polymer's sensitivity to heat and shock,and therefore improved its IM properties relative to NC.The formulation,development and small-scale characterization testing of several CAN-based propellants were done.The formulations,using insensitive energetic solid fillers and high-nitrogen modifiers in place of nitramine were completed.The small scale characterization testing,such as closed bomb testing,small scale sensitivity,thermal stability,and chemical compatibility were done.The mechanical response of the propellants under high-rate uni-axial compression at,hot,cold,and ambient temperatures were also completed.Critical diameter testing,hot fragment conductive ignition(HFCI) tests were done to evaluate the propellants' responses to thermal and shock stimuli.Utilizing the propellant chemical composition,theoretical predictions of erosivity were completed.All the small scale test results were utilized to down-select the promising CAN based formulations for large scale demonstration testing such as the ballistic performance and fragment impact testing in the105 mm M67 artillery charge configurations.The test results completed in the small and large scale testing are discussed.Thelma MANNING Jeffrey WYCKOFF Carlton ADAM Eugene ROZUMOV Kenneth KLINGAMAN Viral PANCHAL Joseph LAQUIDARA Mike FAIR John BOLOGNINI Keith LUHMANN Steve VELARDE Christine KNOTT Stephanie M.PIRAINO Kevin BOYD 2014Defence Technology(防务技术)2014,10,2:2
