Wind power in America, for example, inflates and deflates on a two-year cycle, as a particular tax credit is renewed and then lapses again.

比如美国的风力发电行业，产值的升降以两年为一个周期，这是因为一项特殊的税率信任案在此间被反复提出与搁置而造成的。

Wind power in America, for example, inflates and deflates on a two-year cycle, as a particular tax credit is renewed and then lapses again.

例如，美国的风能就以两年为一个周期起起落落，一旦某项优惠政策期限已满，随之而来的就是新一轮的萧条。

Wind power in America, for example, inflates and deflates on a two-year cycle, as a particular tax credit is renewed and then lapses again.

比如在美国，随着某项税收减免政策的出台和继而失效，风能产值以两年为周期随之起起落落。
