from the analysis of current market price, the initial investment of direct air-cooling system is lower than surface type indirect air-cooled system. two system basically have the same overall economic efficiency.

in other words, it is the volatility that, given a particular pricing model, yields a theoretical value for the option equal to the current market price.

换句话说，给定一个定价模型，该波动性所得到的理论价和当前的市场价一致。
