A j, υ model for the analysis and prediction of tides
Chen Zongyong, Huang Zuke, Zhou Tianhua, Tang Enxiang, Wang Yuzhou
1990, (4): 475-486.
Abstract:
In this paper, the j,υ corrected formulae of the amplitudes and the phases of 58 astronomical constituents are given, and the models for the analysis and prediction of 169 constituents are presented. The new Cartwright's calculated results of the tid...
A three-dimentional model of the northeast East China Sea, with application to the M2 current field
Tang Yuxiang
1990, (4): 487-498.
Abstract:
A simple three-dimensional tidal model is used to examine the M2 tidal current distribution in a northeastern part of the East China Sea, especially the vertical variation of the current in the region. Computed M2 current is compared with observation...
A numerical study for the coastal upwelling and the coastal front off Zhejiang coast
Liu Xianbing, Su Jilan
1990, (4): 499-512.
Abstract:
A two-dimensional numerical model is constructed to study the interaction between the coastal upwelling and the coastal front off Zhejiang coast in summer. In the f-plane model, the shelf topography, continuous stratification, and Richardson number-d...
Marine Meteorology
Analysis of the air-sea heat exchange during the El Nino event in 1983
Zhu Yafen, Yang Dasheng
1990, (4): 513-526.
Abstract:
In this paper,by using the ECMWF objective analysed data as well as CAC and NOAA grid point data of 1981 and 1983,the sensible and latent heat fluxes at the air and sea boundary surface within the range of 45°E-75°W, 35°N-35°S over the Pacific and th...
The PNA wavetrain and the sea surface temperature in the Northern Pacific
Lin Xuechun
1990, (4): 527-538.
Abstract:
In this paper, the response of the atmospheric 3-5 year cycle to Northern Pacific SST is discussed, The results are as follows:
1. From the simultaneous temporal correlations between the Equatorial Eastern Pacific SST, the westerly dirft area's SST an...
The effect of unstable inertia-gravity wave on the occurrence and the development of typhoon and tropical cyclone
Niu Xuexin
1990, (4): 539-546.
Abstract:
In this paper,the analysis of the occurrence and the development of typhoon and tropical cyclone is made with the unstable theory of wave. The result indicates that the primary wave is the unstable inertia-gravity wave in the process of the occurrenc...
Marine Chemistry
Study of aquatic chemical characteristic in some bays along the coastal region of Zhejiang Province
Wang Yuheng, Dong Henglin, Jiang Guochang
1990, (4): 547-554.
Abstract:
In this paper,the aquatic chemical characteristics in the Hangzhou Bay,Xiangshan Bay and Leqing Bay along the coastal region of Zhejiang Province are discussed. Results show that the seasonal variations of chemical elements are obvious. The distribut...
Oscillopolarographic determination of microsillicon in seawater
Chen Liyi
1990, (4): 555-560.
Abstract:
A new oscillopolarographic method for the determination of Si (Ⅳ) is described in this paper. In the system HCl-Sb(Ⅲ)-Mo(Ⅵ)-NaCl-ethyl alcohol, Si (Ⅳ) with Sb (Ⅲ) and Mo (Ⅵ) form ternary heteropoly acid. The anion of ternary heteropoly is adsorbed on...
Marine Geology and Geomorphology
Fossil fauna and transgressive.sequence from core QC2 in the South Huanghai Sea
Zhu Xionghua, Lin Hemao
1990, (4): 561-578.
Abstract:
According to palaeoenvironmental analysis on the fossil fauna dominated by Foraminifera and Ostracoda, core QC2 contains 8 marine transgressive beds, called (from up to bottom) Transgressive Beds Ⅰ,Ⅱ, Ⅲ, …,Ⅷ respectively. Together with dating data, t...

Preliminary study of gonadotropin-releasing analogue (GnRH-A) initiated gonadal development of amphioxus
Fang Yongqiang, Qi Xiang, Liang Ping, Hong Guiying
1990, (4): 579-585.
Abstract:
Amphioxus in the seasonally regressed phase of gonadat development were used in this study. Each sample animal was injected with 40 nanogram of synthetic gonadotropin-releasing hormone analogue (GnRH-A) in distilled water every other day for up to 16...
Marine Engineering
Application of Monte-Carlo statistical experiments in design of ocean engineering——Estimating the parameters, models and probabilities
Liu Defu, Shi Jiangang, Zhou Zhigang
1990, (4): 587-597.
Abstract:
Recently, some results have been acquired with the Monte-Carlo statistical experiments in the design of ocean en gineering. The results show that Monte-Carlo statistical experiments can be widely used in estimating the parameters of wave statistical ...
A stability analysis for the sheared oil film contained by the boom
Zhao Wenqian, Jiang Wei, Wu Zhiwei
1990, (4): 599-610.
Abstract:
According to the observation in experiment of stability of the oil film, the assumption of velocity distribution for both the water flow and the oil film is introduced. On the basis of the assumption, Orr-Sommerfeld stability equation is applied to d...
