        摘要：In this paper, the characteristics of the tides and tidal currents in the Jiaozhou Bay have been analysed on the basis of the data observed. The tide of Jiaozhou Bay is of semidiurnal type. The low water inequality is more remarkable than the high water inequality. From the mouth of the Bay to it's closed end, the tidal range and high water level increase gradually,whereas the low water level decreases.Correspondingly, the duration of the raising tide decreases and that of the falling tide inereases, whereas the intervals of the high and low waters increase gradually.

        摘要：The general characteristics of typhoon surges at the mouth of the Zhujiang River (Pearl River ) are analyzed in this paper.The fundamental mechanisms of storn surge such as 1) the change of storm surge in relation to the typhoon track and wind; 2) the relations between surges and velocity of the river flows; 3) the seiche and wave are also discussed according to theoretical model.

        摘要：The evolution and sand source of the bar off the Fangcheng Port was under investigation from 1974-1978, the result of which indicated that this bar is a residue of the delta of the ancient Fangcheng River. Analysing the minerals and grain size, we found that the sand of the bar mainly came from the ancient Fangcheng River, and the sand carried by the present Fangcheng River has little effect on it. By using the methods of the comparative photographic map and calculation of wave and tide energy,silt accumulated on this part of waerway is found to be about 2.1-2.8×104m3 annually.The outer waterway is eroded in winter, and the sand again accumulated in summer. It is supposed that the amount of accumulation will be about 5-10×104m3 annually when the outer waterway is dragged to the depth of 7 m. The above mentioned result has been comfirmed by measurement from 1979-1981.

        摘要：Comparative studies were made on the yield, properties and composition of agar from 10 species (28 samples) of Gracilara collected on the China coast. The results obtained are listed in Tables 1 and the infrared spectra of which are shown in Figs.1,2,and 3. There exists. a close correlation between the physical properties ( gel strength, gelation and melting temperature) and the chemical composition. The gel strength, gelation and melting temperature of agar extraeted have the positive correlation with 3, 6-anhydro galactose content and the negative correlation with sulfate content. The yield, properties and composition of, agars obtained are different and dependent on the species of Gracilaria, the season and site. Of eollection. Comparatively speaking, G.verrucosa, G. tenuistipitata and G. sjoestedtii at raw materials for agar production are better than other species studied.

        摘要：Experiments about the influence of raw material pretreatment on the quality of algin at different durations of time, concentrations and temperatures of formalin solution were carried out. The influence of formalhyde on the extraction rate of align and the principle of chemical, reaction between formalhyde and some reducing substances were also discussed in this study.

        摘要：The present paper is a supplementary report on the Opisthobranchia of the Hainan and Xisha Islands. Twenty nine species and 2 subspecies, belonging to 24 genera and 17 families are added. Among them, 18 species are recorded for the first time from the China coasts. Specimens were collected by the Institute of Oceanology, Academia Sinica and South China Sea Institute of Oceanology, Academia Sinica, during the past years. The characteristics of the Opisthobranchia fanna of the Hainan and Xisha Islands may be summerized as follows.

        摘要：The present paper is the seventh part of systematic studies on the Cirripedian fauna of Chinese waters based on materials colected by the Institute of Oceanology, Academia Sinica, during the years 1950-1980. Seventeen species belonging to 6 genera were identified. Of these, 4 species are described as new, 9 are recorded for the first time from Chinese waters. The type materials of the new species are deposited in the Institute of Oceanology, Academia Sinica at Tsingtao.

        摘要：Subfamily Mysinae is one of the most important groups of planktonic Crustacea in the shallow coastal waters of the continental shelf in the China seas and is rich in species and abundance. They are fished by local fishermen with fixied net in eertain coastal areas with strong tidal flow (current) and are distinguished by their flavour. Produced by fermentation; they are also used freshly for food. In recent years they have also been utilized as feeds for fish and sea horse (Hippocampus) aquaculture. Consequently, ecological and biological studies of this group of Crustacea inereased fastly in recent years. The present paper is a systematic study of the subfamily Mysinae collected from the northern part of the South China Sea. A total of 32 species belonging to 3 tribes and 17 genera are identified and described. Of these one is new to science and 10 are recorded for the first time from Ghinese coast of the South China Sea. The type materials of the new species are deposited in the Institute of Oceanology, Academia Sinica at Qingdao. Species in the Tribe Mysini inhabited mostly the bottom layer of coastal waters, some of them are cultivated in ponds in very high density.
