- 摘要：The characteristics of the typical processes of the extratropical storm surges and the 18 processes of the typhoon surges during the years from 1949 to 1974 are analysed in this paper, Some characteristics of typhoon surges along the different tracks of typhoon in the Bohai Sea are described. The seiche, the waves and tide-surge interaction are also discussed. The storm surges in Bohai Sea are studied using the fundamental hydrodynamic linearized equation of motion, together with the equation of continuity and the viscous boundary conditions along the closed boundary (coast).An approximate solution was obtained by Laplace and finite cosine transforms and calculu of variations. A process of Typhoon is computed. Theoretical results correspond generally with observations.关键词：STORM SURGES;BOHAI SEA

发布时间：2023-04-28 - 摘要：This paper deals with the acoustic behaviour and all the possible underwater sound signals of Finless Black Porpoise, which is common in China, under semi-natural condition.After analysing and processing the underwater sound signals in laboratory, three kinds of echo location pulse are found in a specific environment: (1 )low frequency modulated pulse (1-2kHz); (2)high frequency modulated pulse (6-8 kHz); (3)plosive modulated pulse.The paper also presents more than ten different types of continous sound signals and their frequency spectrums. Comprehensive analyses of the relationship between the sound signals and the field behaviour data of Finless Black Porpoise prove that its echo location ability depends mainly on the three kinds of sound pulse mentioned above, while continuous sound is secondery And communication (or language ) between the Finless Black Porpoises is performed by means of several kinds of continous sound signal with harmonic feature.关键词：ACOUSTIC BEHAVIOUR;FINLESS BLACK PORPOISE;UNDERWATER SOUND SIGNALS

发布时间：2023-04-28 - 摘要：In the first part of this paper, the design method and main technique data about the mooring buoy system are described in detail. This buoy system is generally available for shallow sea where the water depth is no more than 100 meters. It can still function well in weather conditions of force-7 wind, and is not damaged in force-9 wind conditions. In the second part,information about sea experiment for using the system is related.The mooring buoy system experiment was conducted in Aptil 20th-25th, 1979 and good data on current velocity was obtained by a self-printing current meter, model HLJ1-1, hanging from the buoy by a wire. Experiments made by throwing and recovering the buoy are also summarized. Finally, a comment about this buoy system is made after another experiment and suggestions for improving this buoy system are given.关键词：A MOORING BUOY SYSTEM

After analyzing the experimental data, regression equation can be shown. as follow : Chlorophyll-a (mg/m3)=6.33-8.47 R500. The Haihe River water with its high chlorophyll-a content appears deep blue and the Ji-yun River water with its high suspended sediments is blue green on the color infrared photographs. So that it is easy to discriminate the two waterbodies with different water quality on the images.关键词：THE DISTRIBUTION OF CHLOROPHYLL-A;REMOTE SENSING

发布时间：2023-04-28 - 摘要：One of the most remarkable paleo-geomorphological units in the Liaodong Bay is Liaodong Shoal, which was shore sedimentation during the low sea level in late Pleistocene or early Holocene and have since been violently reformed. Liaozhong Depression, which might have been a paleo-lake or paleo-lagoon, is located to the north of Liaodong Shoal. In the Liaodong Bay, there are many buried paleo-channels,among which Dalinghe-liaohe paleo-channel is the longest. Those paleo-channels once injected into Liaozhong paleo-lake(or paleo-lagoon ) from different directions In addition, therevare paleo-barriers, paleo-dunes, which were formed during low sea level, and some relicts can still be found on them. They might have been paleo shore sediments. The development of above mentioned paleo-geomorphological units and relicts depends upon many factors, such as hydrodynamical regime, ununiformity of the distribution of the deposits velocity in different regions, and the change of the sea level etc. Although the solid discharges to the Bohai Sea by the Huanghe River are estimated at 1, 200 million tons annually, approximately 70% of the deposits are in shallow area near the river mouth. In addition, submarine erosion is advantageous to the development of those paleo-geomorphological units and relicts. Based on the paleo-geomorphological data two paleo-shorelines might have existed in the Liaodong Bay, one at the water depth of about 30 m and might have been formed 9000-10000 years ago, and one at the depth of about 20-25 m and formed about 7000-8000 years ago. According to the characteristics of its paleo-shoreline and three shell banks of the west coast of the Bohai Bay, the region might have gone 5 times through relatively halting or pulsative changes since late pleistocene or early Hlolocene.关键词：PALEO-GEOMORPHOLOGICAL UNITS;RELICTS LEFT OVER;LIAODONG BAY

发布时间：2023-04-28 - 摘要：A preliminary attempt was made to reconstruct climatic conditions in the Ningbo Coastal Plain, Zhejiang Province, based on microfossil analysis of a core drilled on the southern coast of Hangzhou Bay, Bast China Sea. Reaults of analysis show that spores and pollens are rich in the middle and upper parts but scarce in the lower part, and nine sporo-pollen zones are distinguishable from the Upper Pleistocene upwards. Changes in the feature of sporo-pollen assemblages indicate Pleistocene climatic fluctuations and suggest three cool periods, the late Middle Pleistocene, the early and late Late Pleistocene (Q23, Q31 and Q33).During the late Late Pleistocene, which was synchronous with the Dali Glacial Age, the temperature was about 10°C lower than that of today and the weather was not very cold in comparison with that of the innerland, suggesting that this area might have had been in the frontal zone of the glacial borderland. In contrast, the early and the middle Late Pleistocene (Q31 and Q32), and the Holocene were three warmer periods. However, the Holocene can be subdivided into four subperiods. The middle Holocene climate was relatively damper and hotter, with the temperature 1-2°C higher than today. The climatic fluctuations brought about changes in the nature of the vegetation. In the cold weather of the Late Pleistocene,cold-tolerant types such as Abies, Picea and Larix flourished in the conifer-broadleaf forest and forest-grassland. In the ajacent mountain region existed a small tract of Abies beshanzuensis, just like that thriving today in Qingyun County, southern Zhejiang. The middle Holocene found many kinds of evergreens and broadleaf species, such as Quercus glauca and Castanopsis, etc, but less in quantity, indicating that the climate then had been comparatively sultry. The three layers of marine sediments recorded the three transgressions on the Ningbo Plain. The whole area was under the influence of the Holocene transgression,which might have been a little earlier (about 7000-8000 yrs BP)than that happening on the northern part of China coast. The sediments deposited during the two upper Pleistocene transgressions, however, were not so typically marine as the Holocene. The latter two transgressions influenced only the northern and middle parts of the plain. The crustal oscillations of the area investigated are different from those of the Shanghai area and of the coastal plain on the west of the Bohai Sea but are comparable to those happening on the southern coast of the Haizhou Bay. The difference might be attributed to changes in the sea level, in the original topography and in the geomorphological movements,etc.关键词：QUATERNARY;ENVIRONMENTAL CHANGES;NINGBO

发布时间：2023-04-28 - 摘要：According to the morphological and physiological characteristics, the developmental period from the fertilization to the larval fish just produced is divided into eight stages. Unfertilizated eggs are long ellipsoid in shape with one being bigger and the other smallar. The cytoplasm is gradually accumulated at the animal pole after fertilization. These eggs change into spherical shape two hours and forty minutes after fertilization at the temperature of about 28-29℃. The process of the cleavage and the gastrulation is the same as that of the ordinary fish. The oil globules are gradually accumulated towards the animal pole before gastrulation and then slowly move to the vegetable pole. In six days after fertilization, the length of the tail gets slightly longer than the body.The embryo is hatched out by another half day or one day. During the same period, the caudal-fin membrane is also formed, which is gradually degenerated on the second day after the larva is released. The incubation period is 19days at 22.5士0.5℃,16 days at 24 士0.5℃ and 11 days at 28.5 +0.5℃. The most optimum temperature range for its brooding is roughly from26°Cto30°C.关键词：HIPPOCAMPUS TRIMACULATUS;DEVELOPMENT OF EMBRYO

发布时间：2023-04-28 - 摘要：The aspidochirote holothurians are mostly large benthic animals common in tropical and subtropical waters, especially in the Indo- West Pacific area. Nearly all the edible species belong to this order. It is therefore important to study the Taxonomy of aspidochirote holothurians. A total of fifty species was reported by the following investigators as Ludwig(1875),Theel(1886), Heding(1934), Chang (1934, 1954), Chang and Liao(1963), Chang et al(1964)and Liao(1975, 1980 ). R list of the species is given on page 221. In the present paper some description are given for the species which had not yet been described in China. The material upon which this report was based was collected by the Institute of Oceanology. Academia Sinica, in the past 28 years. Most of the specimens came from the littoral region, but some were dredged out by the benthic biological survey.关键词：ASPIDOCHIROTE HOLOTHURIANS

发布时间：2023-04-28 - 摘要：The genus Acaudina Clark, 1907 is one of the commonest groups of holothurians along the coast of the China Seas, from intertidal zone to the depth of 122 meters. During the past thirty years, a lot of specimens of Acaudina were collected from various localities. Recently I have made a detailed study on these materials. More than 800 specimens coming from the entire Chinese coast were examined. They comprise two species: the one is A.molpadioides (Semper) the other, A. leucoprocia (H. L Clark). A. delicata (H. L. Clark) is considered a synonym of A.molpadioides (Semper) and A irania (Heding) a synonym of A. leucoprocta (H. L. Clark ). I suspect that A. gephyra (Sluiter, 1914) may prove to be an abnormal specimen or a regenerate individual of A.molpadioides (Semper). The variation of spicules found in both A. molpadioides (Semper) and A. leucoprocta (H. L. Clark) during growth was described.
