【摘要】 依据土壤工作部件减粘降阻的基本原理，设计了表面仿生改形和表面喷涂搪瓷材料的两种圆盘开沟器，采用正交试验，研究了圆盘偏置参数、工作参数对工作阻力的影响。分析了两种单圆盘开沟器的减粘降阻效果。更多还原

【Abstract】 オwo types of disc opener was designed according to the principle of adhesiondecreasing and resistancereducing of the soil working parts. The relationship between the parameters of disc and it’s working and the resistance of disc opener was measured according with the orthogonal testing method. The results of adhesiondecreasing and resistancereducing of these opener were analysed.更多还原
