| 6. | Exceptionally high waves small and medium - sized ships might be for a time lost to view behind the waves ; the sea is completely covered with long white patches of foam lying along the direction of the wind ; everywhere the edges of the wave crests are blown into froth ; visibility affected 内陆很少见,会引起广泛损坏波涛澎湃,浪高足以遮掩中型船只长片白沫随风摆布,遍罩海面,能见度受到影响 |
| 7. | In the modern power system , acute fluctuation of load lead to great difference of wave crest and trough , abundance non - linear load make severe aberrance of current and voltage wave . these factors make remarkable increase of error of energy metering and unrational billing 现代电力系统中,负荷波动剧烈使负荷峰谷差值很大,大量的非线性负荷使电流、电压波形畸变严重,这些因素使电能计量误差显著增大,并使计费不合理。 |
