Backup power could also be provided by linking wind farms with a solar cell, with conventional or pumped-storage hydropower, or with efficient natural-gas-burning turbines.
将风力发电厂与太阳能电池、常规或抽水蓄能的水电或高效的天然气涡轮机连接起来，也可以提供备用电力。

The maximum modulation depth of the gascell is calculated as 42%, which is in good agreement with the experimental result.
计算了气体盒的最大调制度，其值为42%，与实验所得到的最大调制度很好地符合。
