Nitrous oxide emission (N2O) from applied fertilizer across the different agricultural landscapes especially those of rainfed area is extremely variable (both spatially and temporally), thus posing the greatest challenge to researchers, modelers, and policy makers to accurately predict N2O emissions. Nitrous oxide emissions from a rainfed, maize-planted,(More)
Generally, mechanical wear is divided into 3 stages: wear-in, normal wear and rapid wear. It is important to judge which wear stage the machine is at to reduce failures. Abundant information on machine wear can be taken from lubricant, especially wear particles in it. Wear particles shows the amount of wear and information of wear stage directly, so(More)
