| 摘要: |
| 南黄海浅水陆架区是我国重要经济海域之一,对该海域海流结构的研究是研究陆架环流的一个重要环节。虽然关于这项研究的论著颇多。但根据描述统计学方法研究中国海海流结构的论述至今却极少。本文根据我国海洋地质调查局较长时间的海流观测资料，以描述统计学的分析方法,对南黄海实测流速的统计特征进行了初步分析。
文中引用的实测流速数据的观测站分布于偏近我国的南黄海陆架上。共选取三个观测站,分别以A,B,C标示,三者近似地呈等腰三角形分布,A,B站的连线近似地与经线平行。观测日期颇长,分别是1975年4-5月。1976年4-8月和1977年4-7月。本文着重研究南黄海近表层(5米层)4-6月实测流速谱的特性,所以,统计分析结果反映的是南黄海近表层海流在春夏交替季节的特性。实测流速数据的采样时间间隔均取每15分钟一次。观测仪器系国产HLP1-1印刷海流计。各观测站上截取的观测数据组数见表1。 |

| Abstract: |
| The energy spectrum of the measured current velocity near the surface of the South Yellow sea was studied with the modern descriptive statistics. Ihe data cited here were taken from the National Marine Geological Suevey during the years 1975-1977. This paper consists of three main parts: 1) discussion of the stationary stochastic or quasi-stationary random of the measured current velocity; 2 )a method on determinating the time series data length ensured statistically; and 3 )an analysis on the character of the energy spectrum of the measured current velocity near the surface of the South Yellow Sea. |
