Electrical storage devices known as capacitors charge and discharge very quickly, but because they hold their charge on the surface of metal plates, their storage capacity is limited.

电荷存储元件——电容器，可以快速地充放电，但是因为电荷被存储在电容器金属片的表面，所以电荷容量有限。

With the engine performing at full capacity, the batteries would be drained in the space of 10 minutes -- if they were even chemically capable of withstanding such a rapid discharge.

当发动机的功率耗尽时，电池在10分钟内就会耗竭——如果连续不充电，它们还能靠化学反应支撑的话。

Most NiMH batteries can accept discharge rate up to 3 times its capacity. A higher discharge rate will yield lower capacity.

大多数镍氢电池可以接受3倍于自身容量的放电速率。高放电速率会导致释放更少的电量。

Shell told MPs that in Alaska available mechanical recovery assets had "a combined capacity that exceeds the worst-case discharge potential of the well we are drilling".

According to the testing performed to date at the Ohio State University's Center for Automotive Research (CAR) and the very low observed rate of aging, cells built with A123's Nanophosphate EXT are expected to be capable of retaining more than 90 percent of initial capacity after 2, 000 full charge-discharge cycles at 45 degrees Celsius.

"BP must identify in the next 48 hours additional leak containment capacity that could be operationalised and expedited to avoid the continued discharge of oil, " wrote Rear Adm James Watson.
