An implicit method using contravariant velocity components and its application to calculations in a harbour-channel area
Shi Fengyan, Kong Yazhen, Ding Pingxing
1998, (4): 423-432.
Abstract:
The key problem in the computation of fluid dynamics using fine boundary-fitted grids is how to improve the numerical stability and decrease the calculating quantity.To solve this problem,implicit schemes should be adopted since explicit schemes may ...
Calculation of current in the Taiwan Strait during summer Ⅱ.Three-dimensional semidiagnostic and prognostic calculations
Wang Huiqun, Yuan Yaochu
1998, (4): 433-446.
Abstract:
The semidiagnostic and prognostic models are used to compute the current in the Taiwan Strait with wind and hydragraphic data collected during August,1984 and September 1-6,1988.This calculation can be divided into two stages,i.e.(1) the adjustable s...
Analyses of factors forming offshore SST anomaly(O-SSTA) in China seas
Wang Sizhen, Li Xuhua, Qi Jianhua, Su Yusong
1998, (4): 447-457.
Abstract:
Based on the observations,the location and the strength of warm(cold) anomaly of SST in summer are controlled mainly by the subtropical highs of atmosphere(typhoon track) on the offshore of the China seas.It may be considered from the physical causes...
Derivation of sea surface current field from sequential satellite images of the East China Sea
Liu Qingge, Pan Delu, Pan Yuqiu, Lutz Bannehr, Guenter Warnecke
1998, (4): 459-468.
Abstract:
A series of NOAH AVHRR data over the East China Sea were collected from the ground station of the Institute of Oceanography,Hangzhou,China.Three methods,including a functional analytic method FAM),a maximum cross correlation(MCC)' method and a correl...
Classification of highly turbid Jiaojiang Estuary
Dong Lixian
1998, (4): 469-482.
Abstract:
The Jiaojiang Estuary is shallow,macro-tidal dominated and extremely turbid,with a larger variation of the freshwater discharge.The estuarine stratification and classification are analysed by using a set of field data observed in wet season.
In spring...
Dynamics of DOC of euphotic layer in the Taiwan Strait——Diurnal variation of large range
Peng Xingyue, Hong Huasheng, Shang Shaoling
1998, (4): 483-493.
Abstract:
Three oceanographic investigations from 1994 to 1995 in the Taiwan Strait show that the dissolved organic carbon in the euphoric layer has.large-scale diurnal variation[2-4 mg/dm3],and its amplitude range has spatial and seasonal changes.Generally,th...
Study on purification and ultrastructure of a baculovirus in Penaeus chinensis
Shi Tuo, Kong Jie, Bao Zhenmin, Liang Xingming, Liu Ping, Wang Chongming
1998, (4): 495-502.
Abstract:
A kind of baculovirus was isolated from the cephalothorax homogenate of sick or morbid Penaeus chinensis by differential centrifugation and density gradient centrifugation.Electron microscopic examination of ultrathin section of the gills,stomach and...
Fate of particle-reactive pollutants in the Xiamen Bay
Chen Min, Huang Yipu
1998, (4): 503-508.
Abstract:
A simple model is established to describe the fate of particle-reactive pollutants in the Xiamen Bay.Based on the conditional distribution coefficients(Ka)of chemicals and residence times of particle and waters,the model can be used to predict the fr...
Late Quaternary diatom and sea level changes in estuarine plain of the Jiulong River
Chen Wenrui, Lan Dongzhao, Chen Chenghui
1998, (4): 509-518.
Abstract:
Four units and twenty-four zones of diatom have been discerned in the Borehole ZKS in the estuarine plain of the)iulong River,Fujian Province.Comprehensive analysis of these,together with microbiological assemblages and age determinations in some oth...
Paleoceanographic events of the southern Okinawa Trough during last 20 000 years
Li Baohua, Zhao Quanhong, Wang Yongji, Jian Zhimin, Chen Ronghua
1998, (4): 519-530.
Abstract:
Two high resolution down-mres(92-255,92-170) are used to study the paleoceanographic events of the southern Okinawa Trough during the last 20 000 years.Planktonic foraminifera are quantitatively analyzed and three paleoceanographic events are recogni...
Studies on pathogen of explosive epidemic disease of shrimp Ⅱ.Purification of pathogen
Wang Jinxing, Liu Changbin, Zhang Hongwei, Zhao Shuangyi, Zhang Yanjun, Zhao Jing
1998, (4): 531-536.
Abstract:
The pathogen of explosive epidemio disease of farmed Chinese shrimp(Penaeus chinensis)was isolated and purified from the cephalothorax and hepatopancreas of diseased shrimps by means of different speeds of centrifugation and sucrose gradient ultracen...
Multivariate analysis for ordination and comparison of size of Artemia cysts
Tang Senming
1998, (4): 537-544.
Abstract:
It is known that the biometrics of brine shrimp cysts is of strain inherent.The analysis and comparison of the cyst characters for the identification of unknown cysts from different geographical origin become possible.In this paper,multivariate metho...
Occurrence and distribution of vibrios in fishes and shellfishes in coastal waters of Hong Kong
Xu Huaishu, Li Jun, Phyllis Brayton, Norman Y. S. Woo, David Swartz, Zhang Shuting, Rita R. Colwell
1998, (4): 545-553.
Abstract:
The summer occurrence and distribution of vibrios in the fishes and shellfishes in the coastal waters of Hong Kong were investigated.A total of 69 strains of vibrios were isolated from all samples examined.The strains,along with 10 reference strains ...
