Experimental investigation of power output and soot emission for micro-emulsification diesel oil using for vehicle

The micro-emulsification diesel oil with water dopant of 5%, 10% and 15% was prepared using the NAA micro-emulsification compound developed by the authors. The engine bench testing was carried out on the 485QB diesel engine. From the testing results of velocity, loading and exhaust gas, it can be seen that the power decreases and the fuel consumption increases using the micro-emulsification diesel oil. But based on the actual fuel consumption, the use of emulsification diesel with water dopant of 10% can get the effect of oil saving; while with water donant of more than 15% , it doesnt work evidently. The investigation shows that using the micro - emulsification diesel oil, we can reduce the exhaust gas pollution and receive better environment benefit.

污水灌溉对小麦生长影响试验研究

随着水环境条件的恶化,污水越来越广泛地应用到农田灌溉中。为此,通过小麦盆栽室内实验,着重探讨了在不同污灌条件对小麦生长和产量的影响。实验设置了4种灌溉水质(清水、稀释1倍污水、稀释0.5倍污水、污水)对小麦进行灌水处理。结果表明,污水灌溉降低了小麦分蘖率,从而导致最终实际产量下降,但污水对小麦株高、穗长、千粒质量的提高却是有利的。
