生命力论证是舰艇设计中一个极为重要的环节,关系到舰艇在作战中能否有效地打击消灭敌人和可靠地保存自己的问题。但在舰艇的设计中往往忽略了这个环节。为提高我海军舰艇的战斗力,本文建议在舰艇设计中增加这个环节,并提出论证的时机、任务、方法步骤及有关的论证计算。所论问题对于潜艇、辅助船舶和商船民船都是适用的,只是系统的结构型式和对其具体的生命力要求不同。 The demonstration of vitality is an extremely important link in the design of a ship. It relates to whether the warship can effectively combat the problem of eliminating the enemy and reliably keeping oneself in combat. However, this aspect is often overlooked in the design of ships. In order to improve the combat effectiveness of our naval ships, this paper proposes to add this link to the design of the naval vessels and put forward the timing, tasks, method steps and relevant calculation of arguments. The issues discussed are applicable to submarines, auxiliary vessels and merchant marine vessels, except for the structural type of the system and its specific vitality requirements.
