The main work of the paper is shown as follows.1 The optimal model of the single and combinatorial hedging based on the constraints of total loss is established.The paper takes the positive profit skenewss as constraint of serious loss\' probability, which the tail of curved shape on density function of the hedging yield elongates right,and the left tail become short.

On the basis of kinematic analysis of beam pumping unit,the general dynamics equation in the form of virtual power was applied to analyze the contribution of every part including balancing weight of a beam pumping unit to crank axle torque in consideration of inertia effects. The exact analytical expression for computing crank axle torque was obtained.
