Ma Ying also pointed out that although oil prices have fallen over the highest point, but Air China will be difficult to enjoy the benefits of lower oil prices, mainly due to the original Air China by the international price of oil procurement Make up for the decline in hedging losses (of the decline in procurement costs higher than the loss of security units) in order to benefit from a decline in the price of crude oil, but because of the signing of contracts, including the other party has the right to determine in advance in accordance with the agreed price of the company to sell a certain number of cycles of Fuel, so the amount of losses may be higher than the drop in oil prices brought about by the decline in costs.

马英九还指出，虽然油价已经下跌了最高点，但航空公司中国将难以享受油价下跌带来的好处，主要是由于国际石油价格在原中国航空采购弥补在对冲损失（在采购成本比更高的安全部队损失下降）下降，以受益于原油价格下跌，但由于所签订的合同，其中包括对方已按照事先确定的权利，与公司商定的价格出售了一定数量的燃料循环，所以损失的金额可能低于石油价格下降所增加的成本下降带来的。

Both viscous damping and air drag force must be introduced into the dynamic models. The experiment is carried out in the single-axis air-bearing test bed according to the experiment scheme in chapter 3. The results demonstrate the validity of the developed model, while the conventional zero-order approximate approach could lead to bad results for some high speed cases.

结果表明了传统零次近似方法在某些条件下已不能正确描述柔性体的刚柔耦合动力学性质，而一次近似的刚柔耦合动力学模型得到的结果与实验相符，从而证实了一次近似耦合模型的正确性和可靠性。

Based on mechanism and vehicle theories theoretical analysis is pursued and normal driving conditions are put forward. The relations are analyzed between load distribution and power consumption. Mechanical formula is proposed. Furthermore in this paper the theoretical model of the total power consumption is established, and the relations of the total minimized power consumption with the air-cushion pressure and the fan revolution are discussed. The optimum operation point is put forward. The dynamic digital simulation studies are carried out on the operating procedure of the half-track air-cushion vehicle on soft terrain. Mechanical parameters and soil mechanics characteristics affecting vehicle power consumption and riding performance are analyzed. At the same time according to the model formula, the automation control problem is discussed. It is a theoretical instruction for further automation control.
