黄清雅与雷歌

黄清雅是雷州一代名声显赫的歌翁。他机智,聪慧,喜爱雷歌,开口即唱,出口成歌,与雷歌结下不解之缘。他的雷歌十分巧妙地运用雷州话的谐音字或语言上的歧义,双关地对人对事,或讽刺、或捉弄、或挑逗、或讥笑、或戏谑,喜笑怒骂皆成歌。     

《雷州歌谣话初集》研究

《雷州歌谣话初集》系清末民初黄景星著述之研究雷州民歌的一部珍贵的历史文献,其所选雷歌数量众多,体裁各异,题材广泛,原汁原味,注重音义注解的翔实性与可靠性,编辑体例具有较强的科学性。作者对每首雷歌字词句篇的鉴赏曲尽其致,对雷歌"赋"、"比"、"兴"之叙述方式与"双关"、"顶针"、"回环"等修辞方式独抒己见,将雷歌分为"口头歌"、"班本歌"、"出榜歌"、"姑娘歌"四类,考辨出雷歌"源于清之雍康间,而盛于乾嘉,衰于咸同以后"之历史事实,值得研究雷歌的学人一读。     

雷歌源头及传播原点探析

在雷州半岛民系结构变迁史与我国悠久而顽强的民歌传统等众多因素作用下,闽南民歌获得落地三雷的历史机遇,并随着雷话的生成及扩张进而本土化生成富有本土气息的雷歌,获得当地民众的文化认可,成为雷州文化重要构成之一。     

塔里木盆地顺南地区火山口地震勘探方法及其与油气关系

塔里木盆地在二叠纪曾发生强烈火山活动,盆地内部广泛发育火山岩,前人对其进行了大量研究,但专门针对火山口的研究还较为缺乏。岩浆沿着火山通道运移至火山口溢出,运移过程中对储层有着明显改造作用。根据钻井和三维地震资料,结合前人研究成果,对顺南地区火山口地震勘探方法及其与油气的关系进行了研究。研究表明:火山口在地震剖面上具有圆顶状、眼状、坑状等形态;根据岩性岩相识别法、厚度分析法、地震识别法及断裂构造分析法在平面和剖面上确定了火山口具有发育火山碎屑岩、火山岩厚度较大、低相干圆点状异常及火山岩层同相轴下弯等特征。此外,对三维地震区内火山口分布规律的研究表明,火山口位置与奥陶系强振幅异常分布有一定相关性,即都受到多组断裂交汇及断裂密集程度的控制;研究区内火山口多位于东部S4井和S5井之间区域,平面上呈不规则圆形,直径多为200~500 m,各火山口间距多为2~4 km,在相干平面图上可见18个火山口,其中8个较为明显。

鄂尔多斯盆地上古生界非常规天然气综合勘探前景

在充分调研国内外页岩气研究方法及早期页岩气研究成果的基础上,综合利用钻(测)井资料及样品分析测试资料,分析了鄂尔多斯盆地上古生界页岩气成藏地质特征。研究结果表明:鄂尔多斯盆地上古生界富有机质泥页岩、砂岩及煤层交互发育,泥页岩单层厚度小,但层数多,累积厚度大,有机质干酪根类型以Ⅱ型和Ⅲ型为主,有机质成熟度高,保存条件好,形成页岩气资源潜力巨大;泥页岩全岩矿物中石英、长石含量较高,泥页岩层脆性大,压裂后容易形成裂缝,有利于页岩气开发;页岩气资源有利区域与致密砂岩、煤层厚度叠合图显示,盆地内非常规天然气资源丰富,垂向分布相对集中,有利于未来非常规天然气集中高效开发。该研究成果为非常规天然气深入勘探开发提供了有益借鉴。

GEOCHEMICAL STUDIES OF Fe,Mn,Co,As,Cr,Sb,Zn,Sc AND V IN SURFACE SEDIMENTS FROM JIAOZHOU BAY

The contents of nearly forty-elements in surface sediments in Jiaozhou Bay were determined using a Neutron Activation Analysis Technique(Grancini,et al.,1976;Li Peiquan et al.,1985,1986;Li Xiuxia etal.,1986).This paper's detailed discussion on only nine elements(Fe,Mn,Co,Cr,Sc,As,Sb,Zn andV)includes their distributions,concentrations,correlationships,material sources,background,etc.Based on Zavaristski's classification method,Fe,Mn,Co Cr and V belong to the second group;As and Sb to theeighth groups:Sc and Zn to the third and sixth groups.It was found that their notably good correla-tionship is mainly due to the similarity of their ionic structures and that their variation is controlled by theFe content(except Mn).The source of sediments is mainly terristrial material,and the composition ofsediment is similar to that of shale and shale+clay.The contents for a large number of ele-ments are within the scope of the background level,but there still is pollution of Zn and Cr,at least in a few stations.

Controlling mechanisms for the trace metals, (Cu,Zn, Cd,Fe, Co and Ni) in anoxic sea water in Saanich Inlet,British Columbia,Canada

A study was conducted on Cu, Zn, Cd, Fe, Co and Ni levels in Saanich Inlet anoxic seawater. Data on the concentration of these trace metals and H₂S, and other oceanographic parameters were obtained in four cruises. Equilibrium models are presented together with in situ data. The results strongly support the assumption that the solubilities of Cu, Zn, Cd, Fe, Co and Ni are controlled by bisulfide and/or polysulfide complexes. The species of Cu, Zn, Cd and Ni are shown to be Cu(S₄) ₂ ³⁻ and Cu(Sn₄S₅)³⁻, Zn(HS) ₂ ⁰ and ZnHS ₂ ⁻ , Cd(HS) ₂ ⁰ and Ni(HS) ₂ ⁰ , respectively. The solid species controlling Fe²⁺ and Co²⁺ are respectively the pyrohotites FeS and CoS. The data illustrates that thermodynamic equilibrium has been established in the H₂S-controlled seawater of Saanich Inlet, and that equilibrium has not been established in the H₂S−O₂-coexisted seawater of Saanich Inlet. The lack of equilibrium in the H₂S−O₂-coexisted seawater is a result of the flushing or mixing of oxygenated seawater with anoxic water. The new species of trace metals are still in the processes of reduction and precipitation. Contribution No. 1428 from Institute of Oceanology, Academia Sinica     

Effects of small peptides,probiotics, prebiotics,and synbiotics on growth performance,digestive enzymes,and oxidative stress in orange-spotted grouper,Epinephelus coioides,juveniles reared in artificial seawater

Aquaculture production efficiency may increase by using feed additives. This study investigated the effects of different dietary additives [w/w: 2% small peptides, 0.01% probiotics( Bacillus licheniformis) and 0.2% prebiotics(inulin)] on growth performance, digestive enzyme activities, and oxidative stress in juvenile Epinephelus coioides reared in artificial seawater of two salt concentrations(13.5 vs. 28.5). Weight gain rate was significantly higher in fish fed the diet supplemented with small peptides, B. licheniformis, inulin, or synbiotics than that in fish fed the basal diet; the greatest weight gain rate was found in fish fed the small peptide treatment [56.0% higher than basal diet]. Higher feed efficiency was detected in fish fed the diet supplemented with small peptides than that of fish in the other dietary treatments. Total protease activity in the stomach and intestines was highest in fish fed the small peptide-treated diet, whereas lipase activity was highest in those fed synbiotics(combination of Bacillus licheniformis and inulin) than that in fish fed the other treatments. Antioxidant enzyme(total superoxide dismutase and catalase) activities and hepatic malondialdehyde content were higher in fish receiving the dietary supplements and maintained in artificial seawater containing 13.5 salinity compared with those in the control(28.5). Hepatic catalase activity in grouper fed the diets with small peptides or synbiotics decreased significantly compared with that in control fish. Overall, the three types of additives improved growth rate of juvenile grouper and digestive enzymes activities to varying degrees but did not effectively improve antioxidant capacity under low-salinity stress conditions.     

Growth,reproduction & population structure of the freshwater crabSinopotamon yangtsekiense bott, 1967, from Zhejiang,China

Monthly investigations were mae on the population of Chinese freshwater crab,Sinopotamon yangtsekiense Bott, 1967 from April, 1984 to March, 1985. The data on 4413 specimens show that the growth was affected mainly by temperature. During the April to November growth period, the crabs' major development occurred from June through October. One year was required for a fine white oocyte to develop into a mature egg. The reproduction period was June–October. Females bearing eggs were taken from June–August, and crabs with young were found from July–October. The females reproduced once a year but could for more than one year. The number of eggs carried by a female varied greatly according to the size of the crab, ranging from 30 to 100 eggs. New-born crabs become mature after 1–2 years. The sex ratio was approximately 1∶1 in the overall population. However, the larger crabs are predominantly male. The age distribution ofS. yangtsekinese was estimated from size frequency histograms. There were more adult crabs (over 70%) from June to October and more immature crabs (over 50%) from November to May.

Requirements of shrimp,Penaeus chinensis O'sbeck for potassium,sodium, magnesium and iodine

Potassium, sodium, magnesium and iodine requirements of shrimp,Penaeus chinensis were studied. Orthogonal design was employed in this experiment. The composition of the basal diet consisted of fish meal, peanut cake, corn meal, soybean cake, wheat bran, vitamin mix and mineral mix, and supplementations of potassium, sodium, magnesium and iodine in the basal diet were made according to the L₉(3⁴) orthogonal table. The results indicated that iodine supplementation improved growth of the shrimp significantly and raised survival very significantly, iodine requirement of the shrimp was 0.003%; sodium requirement was 0.87% or less; and that 1.1–1.3% potassium and 0.18–0.38% magnesium in the diet were proper nutrition supplements for the shrimp.
