(一)护卫舰是一种多用途的舰种,在世界各国海军装备中占相当重要的地位。根据护卫舰所担负的不同任务,可分为反潜、对海、对空和综合型,对动力装置的要求也是各不相同的。 (二)现代护卫舰没有严格的划分标准,有些国家把排水量4000吨的舰称为护卫舰,有些国家的海军把排水量3000吨的舰却称为驱逐舰。现在多数国家海军把500～1800吨的舰称为轻型护卫舰,而把排水量为1800～4000吨的舰称为护卫舰。我国海军对这二类舰通称为护卫舰。本文对动力装置的论述中沿用轻型护卫舰和护卫舰的划分概念。
(A) The frigate is a multi-purpose ship that occupies a very important position in the naval equipment of all countries in the world. According to the frigate’s different tasks, can be divided into anti-submarine, the sea, air and integrated, the requirements of the power plant are also different. (2) There is no strict classification standard for modern frigates. In some countries, the 4,000-ton displacement ships are called frigates. In some countries, the Navy calls the destroyer the 3,000-ton displacement ship. Most navies in the United States now call ships of 500-1800 tons light frigates and ships of 1800-4000 tons displacement as frigates. China’s navy on these two types of ship called frigates. This paper discusses the concept of power plant used in the classification of light frigate and frigate.
