本文以情报资料调查与分析研究为基础,对国外救捞及海洋水下工程科学技术发展水平,作出了力求如实而准确的评定。同时根据其已显露的发展趋势和一些值得跟踪的动向,对各分支未来可能出现的模式及其相互关系,进行了较为审慎地探讨与推测。为我国海洋工程界提供有益的参考。 Based on the investigation and analysis of intelligence materials, this paper makes a rigorous and accurate assessment of the level of scientific and technological development of salvage and marine underwater engineering abroad. At the same time, we have conducted a more cautious discussion and speculation on the possible modes and their interrelationships in the future based on their revealed development trends and some trends worthy of follow-up. For our marine engineering community to provide a useful reference.
