The increase in demand moves output out along the supply curve, increasing cost and therefore price.

需求的增长使得产量随着供给曲线不断提高，由此带来的成本上升最终引起了价格的上涨。

It isoften important to distinguish the demand curve itself – the entirerelationship between price and quantity demanded – from the quantitydemanded.

区分需求曲线与需求数量非常重要。

High prices reduce demand and thus move output down the supply curve, resulting in a new, lower-price equilibrium.

高昂的价格会减少需求从而将产量降低到供给曲线以下，恢复到一个新的、低价格的均势之中。
