摘要
海上仪器设备长期暴露于复杂的海洋环境下,其所处的海上大气环境直接影响仪器设备的腐蚀程度,从而对仪器性能的发挥带来巨大影响。利用NCEP再分析资料提供的1 000 hpa大气温湿度和风速,结合其在对流层的变化规律,推求任意高度大气环境参数,利用模糊C-均值聚类算法,将中国沿海海域划分为几个对腐蚀影响程度不同的区域,为海上仪器设备制造、养护提供环境信息支持。
The instruments on ships are always staying in a complicated ocean environment,the atmosphere condition above the ocean is the key factor to instrument corrosion,which can affect the performance of the instruments severely.In this paper,the NCEP reanalysis data of the atmosphere temperature at 1000hpa and the wind speed is used to calculate the atmosphere parameter,than the fuzzy C-Means clustering technique is used to reveal the underlying relationship of the elements and segment the interrelated ocean in regions with similar spectral properties in the influence of instrument corrosion,which can provide important information for the ship instruments produce and maintenances.
