新版协议移除了此项条款，改为双方根据市场预期与实际接种情况协商确定采购计划，通过书面订单实施滚动采购。这一转变使得智飞生物无需再为未达标的采购量承担违约风险，也不必为完成指标而过度备货，实现了从"先采购后销售"的重资产运营向"以销定采"的轻资产模式的转型。

In either case, while I am not an expert on oil extraction or shipping, what I have seen folks who are experts on those things say is that the return of normal operations after this war will be very slow, often on the order of ‘every extra week of conflict adds a month to recovery’ (which was Sal Mercogliano’s rule of thumb in a recent video). If the war ends instantly, right now, ship owners will first have to determine that the strait is safe, then ships will have to arrive and begin loading to create space in storage to start up refineries to create space in storage to start up oil wells that have been ‘shut in,’ some of which may require quite a bit of doing to restart. Those ships in turn have to spend weeks sailing to the places that need these products, where some of the oil and LNG is likely to be used to refill stockpiles rather than immediately going out to consumers. For many products, refineries and production at the point of sale – fertilizer plants, for instance – will also need to be restarted. Factory restarts can be pretty involved tasks.
