Theoretical wind wave frequency spectra in shallow water
Wen Shengchang(S. C. Wen), Guo Peifang, Zhang Dacuo, Chen Bohai
1988, (3): 325-343.
Abstract:
The method developed by Wen et al. (1988a) for deriving theoretical wind wave frequency spectrum in deep water is extended to the case of water of finite depth, in which a parameter η=H/d is introduced, where H and d represent the average wave height...
Numerical computation of tidal currents in the eastern and southern parts of the East China Sea
Fang Guohong, Yang Jingfei
1988, (3): 344-355.
Abstract:
Numerical simulation on diurnal and semidiurnal tidal currents is made for the eastern and southern parts of the East China Sea bounded by the Tsushima, islands of Kyushu and Ryukyu in the east and extending to the central Taiwan Strait in the south....
The amplifying effect of southern continental shelf of the East China Sea on semidiurnal tides
Zhou Tianhua, Chen Zongyong
1988, (3): 356-359.
Abstract:
The coast of Zhejiang Province is a zone of maximum tidal ranges in China. One of the causes is the influence of the adjacent continental shelf. A model is presented in this paper, whose theory suggests that the amplitudes of semidiurnal tides should...
A preliminary study on mean-field decomposition
Ma Helai, Su Yusong
1988, (3): 360-368.
Abstract:
Two kinds of the empirical orthogonal function analysis method for decomposing the mean-field are developed and a comparison is made between them. It is proved that the mean-field can be decomposed using eigenvectors obtained from anomaly-field decom...

Preliminary experiments from a nonsteady atmosphere-earth surface coupled anomaly model
Lin Benda, Xu Xiaodong, Wang Shaowu
1988, (3): 369-380.
Abstract:
In this paper, a nonsteady atmosphere-earth surface coupled anomaly model is used to conduct both comparative experiments on the physical processes of model and monthly forecasting experiments for anomaly fields. It is shown that after further improv...
The reliability of the wind speed, air temperature and humidity observed on ship
Liu Lianji, Zhao Yongping
1988, (3): 381-387.
Abstract:
Using data of wind speed, air temperature and humidity recorded simultaneously on board and the on the small buoy, the latter is considered as criterion, the paper has discussed the influence of the body of ship on the meteorological data. Owing to t...

A study on the exchange additivity of zinc in solid mixtures in seawater——Ⅲ. Stepwise isotherms of the mixture
Meng Xiaoguang, Zhang Zhengbin, Liu Liansheng
1988, (3): 388-394.
Abstract:
Zinc exchange isotherms in mixtures of hydrous metal oxides and clay minerals have been reported. The relationship between the isotherms of the mixtures and the isotherms of their components is studied. The isotherms of the mixtures are stepwise. And...
Research on hydrous titanium oxide absorbent extracting uranium from seawater by means of XRD, SEM and EDAX
Chen Huizhen
1988, (3): 395-401.
Abstract:
Hydrous titanium oxide (HTO) adsorbents containing the same water content, which were prepared under different temperature cond'tions, were studied by means of valuing uranium-extracting activity, X-ray diffraction (XRD), scanning electron microscope...
The features of temporal variation and the distribution of dissolved oxygen in the western Taiwan Strait
Yi Ruizao, Lin Jianyun, Lu Meiluan, Wang Weiqiang, Huang Shanggao
1988, (3): 402-411.
Abstract:
The distribution of dissolved oxygen in the western Taiwan Strait was discussed by using the method of harmonic analysis. The periodic variation of dissolved oxygen in seawatcr can be expressed by the Fourier series:
Y=A0M=1nAmcos(mωt-Φm),
where A0 ...

Investigation and study on deep-sea cosmic spherules from the North Pacific
Peng Hanchang, Liu Zhengkun, Chai Zhifang, Zhuang Shijie, Yu Zhong
1988, (3): 412-420.
Abstract:
This paper presents the collecting methods of the deep-sea cosmic spherules and three major results analysed with various instruments, and especially indicates that iron spherule with golden Ni-Fe core and silicate spherule with golden Ni-Fe-S inclus...
A new inverse filtering method of gravity field
Jin Xianglong, Gao Zhiqing
1988, (3): 421-434.
Abstract:
A new method for inversion of gravity field using the technique of inverse filtering is presented in this paper to calculate the structure of crust.
After inversing gravity data of West Pacific and Okinawa Trough, it has been proven that the method of...
A force source of tectonic movement-A secondary mass center restoring force
Zhang Dachang
1988, (3): 435-441.
Abstract:
The earth system discussed in this paper is composed of two secondary particle systems:a water body and a base body. The base body shows different behaviours under the actions of long term and short term effects of its rheologic character and viscoel...

Morphology, reproduction, ecology and isoenzyme electrophoresis of Capitella complex in Qingdao
Wu Baoling, Qian Peiyuan, Zhang Songling
1988, (3): 442-458.
Abstract:
Morphology, reproduction, ecology and isoenzyme electrophoresis of a Capitella complex in Qingdao were examined from 1983 to 1984. We determined that the Capitella complex in Qingdao was composed of at least three sibling species:Capitella cf capitat...
Studies on ultrastructure of oocyte in process of maturing in pen shell
Fang Yongqiang, Qi Xiang
1988, (3): 459-472.
Abstract:
The present paper deals with the ultrastructural changes of oocyte in the process of maturing in pen shell Atrinapectinata Linne. When it develops from the antecedent growth period to the accelerating growth period the annulate lamellae emerge, the R...
