曲线

Intuition tells us that by following an optimal pattern which recognizes the difference in factor intensities of the two goods, we can end up on a production possibility curve that is bloated out beyond a constant-cost straight line: in short, on a production possibility curve that is convex, obeying the law of increasing marginal costs of one good as it is expanded at the expense of the other good.

直觉告诉我们，遵循一个最佳的牵式识别不同强度的因素，我们可以结束两种商品生产可能曲线上的突破了constant-cost臃肿直线：简而言之，在生产可能曲线，为凸、守法的边际成本的增加的一个好，因为它是扩大牺牲另一个好。

By the cooling curve and the temperature field, it can he known that, the solidification time of ribbon is 1.0×10^(-4)s, the even solidification rate of ribbon with 60 μm thickness is about 10^6K/s, and the temperature of cooling process does not obviously go back by the release of solidification latent heat. The solidification rate of ribbon is at 0.010-0.394 m/s, and it changes from high to low with the prolonged solidification time.

由冷却曲线和温度场曲线类比结果可知，带子的凝固时间为1.0×10^(-4)s；单辊快淬的平均冷却速度在10^6 K/s数量级，且凝固潜热的释放不会明显地引起冷却过程的温度回升；带子的凝固速度在0.010~0.394 m/s范围之内随凝固时间的延长逐渐由大变小。
