| 1 | Application of Linear Mean-Square Estimation in Ocean Engineering显示文摘The attempt to obtain long-term observed data around some sea areas we concern is usually very hard or even impossible in practical offshore and ocean engineering situations. In this paper, by means of linear mean-square estimation method, a new way to extend short-term data to long-term ones is developed. The long-term data about concerning sea areas can be constructed via a series of long-term data obtained from neighbor oceanographic stations, through relevance analysis of different data series. It is effective to cover the insufficiency of time series prediction method's overdependence upon the length of data series, as well as the limitation of variable numbers adopted in multiple linear regression model. The storm surge data collected from three oceanographic stations located in Shandong Peninsula are taken as examples to analyze the number-selection effect of reference oceanographic stations(adjacent to the concerning sea area) and the correlation coefficients between sea sites which are selected for reference and for engineering projects construction respectively. By comparing the N-year return-period values which are calculated from observed raw data and processed data which are extended from finite data series by means of the linear mean-square estimation method, one can draw a conclusion that this method can give considerably good estimation in practical ocean engineering, in spite of different extreme value distributions about raw and processed data. | 王莉萍 陈柏宇 陈超 陈正寿 刘桂林 | 2016 | China Ocean Engineering2016，30，1： | 3 |
| 2 | 新型海洋纵深温度监测浮筒系统的设计建模与仿真显示文摘为实现海洋纵深垂直温度场分布的定点实时监测,研究了光纤测温传感技术和太阳能技术,设计了一种新型海洋测温浮筒。根据海洋工作环境对浮筒提出的浮力、抗倾覆性、强度以及密封性要求,建立了浮筒的几何模型。通过等效转换,建立浮筒在波浪力作用下的数学模型。并通过仿真实验,验证了浮筒的极限倾覆波幅及浮筒结构的可行性。提出的三浮腔测温浮筒能够测量海洋垂直纵深温度分布,浮力满足安全系数要求,具有较好的抗倾覆性和结构强度,可在海洋中稳定长时间工作。 | 郑荣豪 陆利新 吴海生 | 2012 | 机械设计与制造2012，，9： | 2 |
