To study the effect of phosphorus (P) deficiency on leaf photosynthesis and carbohydrates partitioning and to determine whether the characteristics of leaf photosynthesis and carbohydrates partitioning are related to low P tolerance in rice plants, a hydroponic culture experiment supplied with either sufficient P (10 mg /L) or deficient P (0.5 mg /L) was(More)
Cylinder pressure is an important parameter for engine combustion analysis and fault diagnosis. In order to improve the estimation precision and the tracking speed of cylinder pressure, the method of engine cylinder pressure estimation based on the robust sliding mode observer is proposed. On the basis of the establishment of the engine dynamic model, it(More)
