D. allowed to sit anywhere
题目解答
答案
C. loaded equally on both sides with more aft
解析
本题考查救生筏在未满载情况下人员装载的相关知识。解题思路是根据救生筏的稳定性原理来分析各个选项。
救生筏在水上需要保持良好的稳定性,以确保人员的安全。当救生筏未满载时,合理的人员分布对于维持其稳定性至关重要。
- 选项A:将更多人员装载在左舷前部(loaded more on the port side forward)。这样的分布会使救生筏的重心偏向左舷前部,导致救生筏左右不平衡,并且前部重量过大,容易使救生筏前部下沉,后部翘起,不利于救生筏的稳定漂浮,所以该选项错误。
- 选项B:在两侧均匀装载且人员更多地在前方(loaded equally on both sides with more forward)。虽然两侧均匀装载保证了左右平衡,但人员过多集中在前方会使救生筏的重心前移,同样会造成前部下沉,后部翘起的情况,影响救生筏的稳定性,所以该选项错误。
- 选项C:在两侧均匀装载且人员更多地在后方(loaded equally on both sides with more aft)。两侧均匀装载保证了救生筏左右方向的平衡,而人员更多地在后方可以使救生筏的重心靠后,这样能让救生筏的前部有足够的浮力,后部也能保持相对稳定的状态,有利于救生筏在水上平稳漂浮,所以该选项正确。
- 选项D:允许人员随意就坐(allowed to sit anywhere)。人员随意就坐会导致救生筏的重量分布毫无规律,无法保证救生筏的稳定性,可能会使救生筏在水上出现倾斜、晃动甚至翻覆的危险,所以该选项错误。
