- 摘要：Close relationship between probability distribution of sea level and major moments is confirmed and the dependence of the moments on tidal harmonic constants and standard deviation of non-astronomical sea level variation is given. A method is proposed for calculating probability distribution of sea level from standard deviation and coefficients of skewness and kurtosis. The method is named BPF method according to the Chinese phonetic words of these moments. The results obtained from BPF method? are consistent quite well with the observed values.关键词：BPF METHOD;SEA LEVEL DISTRIBUTION

发布时间：2023-04-28 - 摘要：The present paper suggests taking the sea level corresponding to the accumulative frequency p=0.14% (one hour per month) as the chart datum. The BPF Method is simplified to obtain a method for calculate chart datum and sea level thus obtained is called the near-lowest sea level. A comparison of this method with several currently used methods shows that the nearlowest sea level has the advantages of convenience in calculation and better stability of the results.关键词：BPF METHOD;CHART DATUM

发布时间：2023-04-28 - 摘要：The deep and bottom water within the Huanghai Cold Water Mass (HCWM) in summer time was, for a long time, considered as a homogeneous body of water. Various investigations carried out in recent years have pointed out that this may not be true. After a detailed analysis of the most recently obtained refined CTD data and historical hydrographic data at our disposal, some significant results have been obtained.关键词：INTERNAL HYDROGRAPHIC STRUCTURE;HCWM

发布时间：2023-04-28 - 摘要：This paper discusses the distributions and the removal processes of NO3-N, NO2-N，NH4-N,∑N (total inorganic nitrogen) and PO4-P in the surface water of Changjiang (Yangtze) River downstream and its estuary in October, 1983. The distributions of NO3-N, NO2-N and . ∑N show the similar trend of distribution in Changjiang River downstream water. The concentrations of them are higher in Changjiang River mouth water than in other regions of Changjiang River. The NO3-N concentration in river mouth water is close to 900 μg/L, which is 4 times higher than in 1963, and much higher than the world-wide average concentration in the river water. This increased NO3-N is mainly due to the effect of the sewages drained from the cities and countryside along the river. The distribution of PO4-P in river water is uniform except in river mouth, where higher PO4-P concentration was found. The average concentration of PO4-P in river water is 24.8 μg/L

发布时间：2023-04-28 - 摘要：The middle and posterior regions of digestive tract of the Penaeus orientalis were studied histologically. The observation shows that the prawn’s midgut starts on the junction of the pyloric stomach’s end and its dosal gland, and extends to the rectum and hindgut gland at the distal part of the sixth abdominal segment. The midgut accounts for more than 60% in length of the total alimentary tract. The present authors pointed out that the mistaken idea of the short midgut and the longest hindgut in Penaeus orientalis ought to be corrected.关键词：MIDGUT;PENAEUS ORIENTALIS KISHINOUYE

The specific activities of caseinase, trypsin, carboxypeptidase A and B，α-amylase, maltase and lipase in the hepatopancreases of the prawn are far greater than those of chymotrypsin，β-glucosidase and β-galactosidase. 2. The specific activities of the carbohydrases in the juvenile prawn, including those of α-amylase, maltase，β-glucosidase，β-galactosidase are much greater than those in the spawned female prawn. 3. The activities of caseinase and trypsin can be inhibited by soybean inhibitor or tosyllysy1-chloromethylketone ( TLCK).关键词：DIGESTIVE ENZYMES;PRAWN PENAEUS ORIENTALIS

发布时间：2023-04-28 - 摘要：The activities of proteinase and amylase can be affected by and can respond to the diet the prawn fed in about 5-8 days. The ratio of specific activity of proteinase to that of amylase is directly proportional to the protein content and inversely proportional to the starch content in the diet. The activities of proteinase and amylase of the prawn fed with a diet containing more protein and less starch (fresh fishes 20%, fish meal 80%) are greater than those of the prawn fed with diets containing less protein and more starch (sweet potato flour over 20%) when six diets were used with different fish meal and sweet potato flour ratio in the culture of the prawn.关键词：DIGESTIVE ENZYMES;PRAWN PENAEUS ORIENTALIS

发布时间：2023-04-28 - 摘要：The clam, Arca (Anadara) subcrenata Lischke, which inhabits abundantly in Bohai Bay, is a valuable seafood as well as an indicator in studying seawater pollution by heavy metals and consequently a criteria in establishing water quality. The present paper deals with the research on the accumulation, distribution and depuration of Cd, Cu, Pb, Ni, Cr by this species and the salinity influence on their uptake rate. The clams were first exposed to the five kinds of metals in various concentrations. After being treated by wet digestion, the contents of heavy metals in the samples were determined by WFD-Y2 Atomic Absorption Spectrophotometer.关键词：LISCHKE;ACCUMULATION;DISTRIBUTION;DEPURATION

发布时间：2023-04-28 - 摘要：The effects of tributyltin fluoride in the sea water on the Hydroides ezoensis have been studied. The observation with light and electron microscopies showed that the toxicant diffused from the body surface through the blood sinus into the brain neuroganglion could lead to serious swelling of the central nervous system and set off a chain pathological reaction. There may be two possibilities about the toxic mechanism of tributyltin fluoride. One is the change of the membrane permeability, the other is the inhibition of oxidative phosphorylation, but the former is more strongly suggested.

发布时间：2023-04-28 - 摘要：In the present paper, 10 species and 2 forms of the crustose coralline algae from the Hainan and Naozhou Islands，Guangdong Province, are reported together with a study of their morphology. The specimens used for this study were collected by the members of the Institute of Oceanology, Academia Sinica during 1957-1965, 1973-1976, 1980-1982, and by Prof, C. K. Tseng in 1933-1934. Among them, Mastophora rosea (C. Ag.) Setch. (or as Mastophora macrocarpa Mont.) was already recorded from Hainan I. and Dongsha Is. of Guangdong Provincer[44] and Taiwan Province [8]; the other four species and 2 forms, i.e., Mesophyllum erubescens (Fosl.) Lemoine, Mesophyilum simulans (Fosl.) Lemoine f. typica (Fosl.) Lemoine, M. simulans (Fosl.) Lemoine f. crispescens (Fosl.) Lemoine, Lithophyllum kotschyanum (Unger) Fosl. and Lithophyllum moluccense Fosl. were briefly described for the first time in Common Seaweeds of China[49] recently by the present authors; Hydrolithon reinboldii (W. v. Bosse et Fosl.) Fosl., Lithoporella melobesioides Fosl., Lithoporella pacifica (Heydr.) Fosl. and Porolithon onkodes (Heydr.) Fosl. are compared with the related species from the Xisha Is.The last one, living form of Archaeolithothamnium erythraeum (Rothpl.) Fosl. [ = Sporolithon erythraeum (Rothpl.) Kylin] found in the Hainan I. is new to China, and most of its sporangia are cruciate and some zonate, they are arranged in rather loose sori and generally in several layers. The “ cover cells" characterized by all the members of both genera，Archaeolithothamnium and Lithothamnium, are clearly present in the Hainan specimens of Archaeolithothamnium erythraeum. The argument has long existed among some phycologists on the generic name, Archaeolithothamnium or Sporolithon. In China, 4 fossil species of the genus Archaeolithothamnium had already been found among the late Cretaceous and the early Tertiary calcareous algae distributed in the Qomolangma district of the Himalayas[1], and now, its living species, A. erythraeum, was also collected from the Hainan l. We think it is rather reassonable and logical to use a common generic name for all members of a common genus whether they are fossils or living forms, and not that Archaeolithothamnium only for the fossils while Sporolithon for the livings.关键词：CRUSTOSE CORALLINE ALGAE
