With the development of human society, because of the lack of sustainable utilization consciousness, and the eager for quick success and instant benefit, the black earth suffered excessive cultivation and management, causing the reduction of its recycled ability, decrease in organic content, porosity ratio, fertility dropped and the properties of water retaining and water retention, which make the black soil harden and degenerate seriously
但是隨著人類社會的發展，在缺乏保護和可持續利用意識、急功近利思想影響下，黑土遭到過度墾殖和掠奪式經營，人類對其活動范圍遠遠超過了其再生能力，導致有機質含量減少，肥力下降，孔隙比減小，保水持水能力降低，土壤板結，黑土嚴重退化。 -
It is quite evident that the rm - 80 is not suited to working on the harden ling. in order to make rm - 80 be suited to the conditions in china, we conduct an analyse and a calculation theoretically on excavating obstruction, excavating productivity and traction ability sa well. so that we can choose a better matching of produvtivity to solve problem of insufficient ability of excavation
為使rm80型全斷面道碴清篩機的性能適合我國國情，我們從理論上對該機在板結地段作業時的挖掘阻力、挖掘功率及作業工況下的牽引能力進行計算分析，從而選擇出一種更好的功率匹配關系，解決挖掘能力不足的問題。
