This paper analyses and calculates the plow parameters about two kinds of high speed plows LEMKEN and KUHN, and studys the relation between the geometric parameters of shape of moldboard plow surface and soil properties, plowing quality, forces properties, plowing speed, resistance and energy dissipation during the plowing. Then according to the direction of developing high efficiency and saving-energy agriculture, under the premise of good farming quality this article puts forward a kind of method setting the mathematics model about plow resistance through the new cultivation principle and the new design principle.

本文通过对比分析的手段对LEMKEN和KUHN两种高速犁参数两种犁体曲面参数进行量化分析计算，分析犁体曲面形状的几何参数与耕后质量、土壤的力学特性、耕速、阻力和功率消耗等相关关系，结合目前高效节能型农业的发展方向，提出在保证作业质量的前提下，应用新型耕作理论和新型设计理论建立牵引阻力数学模型。

Tectonic subsidence play dominant role in their geometric shapes, basin fillings, sequence evolution and sediment distribution in the Wushi Sag. Outline of the sequences are in shape of box-wedge or sheet-wedge and boundaries of sequences are varied from bilateral fault to monoclinal fault overlap, so that the sequences show distinct semigrabens which overlay in different ways. Seven sequences were formed in different stage of tectonic evolution. The sequence of SQ1 formed in initial rift stage and deposited alluvial sequence. Sequences SQ2-SQ4 developed in intense rift stage and sediment lacustrine sequence. Sequences SQ5-SQ7 formed in late period of rift before thermal subsidence and deposit mere and delta sediment. The place adjacent to the synsedimentary fault is the subsidence center and depocenter; meanwhile, controlling fracture migrates in horizontal made subsidence and sedimentary center of the sag changed.

构造沉降是控制层序几何形态，充填叠置方式、演化及沉积体系分布的最重要因素：凹陷由多个半地堑在不同层序发育时期以不同方式叠置联结而成；受断层控制，层序外部形态有箱状-楔形、楔形-席状披覆型，边界终止方式有双断终止型、单断终止超覆型；不同构造演化阶段层序内部充填的沉积体系各具特征，初始断陷阶段的SQ1沉积冲积层序，强烈断陷阶段的SQ2-SQ4充填湖相层序，晚期断陷阶段SQ5-SQ7内部充填浅湖和河流三角洲沉积；同沉积断层陡坡带沉降迅速、可容纳空间快速增长，是凹陷的沉积和沉降中心，断陷期主控断裂活动时间和空间的变化导致了凹陷沉积和沉降中心的迁移。
