Apart from safety problem, the problem of speedloss should also be taken into consideration when the vessel is sailing in big stormy waves.
船舶在大风浪中航行除了要考虑船舶安全以外，还要考虑船舶的失速问题。

The prediction of speed-lossin wind and waves cannot satisfy navigators' needs and is currently a subject demanding prompt solution in navigation technology field.
舰船在风浪中的失速预报难以满足海上实践需求，是当前航海科学技术领域亟待解决的课题。
