| | Cole, Mullaly and Watdinson (1967), Little (1967) and Clavelier (1967) respectively made high resolution observations on the sun at long decimeter wave. It is found that the Type-1 sources are narrow,and sometimes multiple, generally double, and have higher brightness temperature. Their altitude is about 70,000 km above the photosphere.We made a series of observations on Type-1 sources too through 1979-1980. The main characters of the compound interferometer used by us were depicted in paper (6). Puring the... | | 本文利用密云460MHz复合干涉仪进一步进行Ⅰ型源的高分辨率研究.文中将Ⅰ型源按形态分类,共分为5类:多重中心;边缘尖锐的单源;边缘模糊的单源;双成份源;无连续谱的源.通过对不同类型源中心——边缘分布和对不同源距计数的分析,我们确定在分米波段Ⅰ型源实质上是多重的.文中还讨论了Ⅰ型源在米波段和分米波段的差别. | | 文摘来源 | | The distributional behavior of the mackerel inhabiting the Yellow Sea and the Bohai Sea bears a close relation to environmental factors such as sea condi- tions and weather.This paper,based on the collected data about fishing conditions, sea conditions and weathers during the years from 1972 to 1979,describes the relationship between the distribution of mackerel and the environmental factors such as water temperatures,water systems,thermal layers,food organisms,wind, atmospheric pressures and moon's age. 1.... | | 黄、渤海鲐鱼的行动分布与海况,气象等环境因素有密切关系,本文根据1972~1979年渔况、海况和气象等资料,分别对水温、水系、跃层,饵料生物以及风、气压、月龄等环境因素与鲐鱼行动分布的关系进行初步探讨,结果表明:1.鲐鱼产卵洄游进入黄海时间与黄、东海表层水温呈正相关系,即水温高鲐鱼进入黄海的时间提早。以黄、东海5月1日表层水温距平值x和黄海中部围网初渔期y(5月y日)为指标,其关系式为:y=9.8762-0.8808x,r=0.678,r>r_(α=0.05)=0.666,S=3.22天。因而4月末至5月初黄、东海表层水温可以作为预测鲐鱼产卵洄游进入黄海时间迟早的重要依据。 2.春汛黄海鲐鱼产卵场的位置与水系分布关系密切。鲐鱼产卵场通常在外海水与沿岸水等不同水系的交汇区。在鲐鱼资源比较稳定的情况下,外海水向北伸展的势力强,鲐鱼产卵场偏北,反之产卵场偏南。而32‰等盐线以及外海,沿岸水系的分布可以做为预测产卵场位置的重要指标之一。3.黄海鲐鱼主要摄食太平洋燐虾(Euphausia pacifica)、细脚蜮(Themisto gracili-pes)和鳀鱼(Engraulis japonicus)等。其索饵场的... | | 文摘来源 | | A total of 72 sporopollen types of terrestrial plants, 7 aquatic plants and several freshwater algae are recognized in 59 surface sediment samples collected from the bottom of the Dianchi Lake, the lagest freshwater lake in southwest China. The sporopollen distribution patterns of terrestrial plants in surface sediments were analysed based on pollen concentrations and pollen percentages. Multinomial fits were made to show relations of water depth with pollen numbers of some herbaceous plants and with number... | | 作者对滇池及草海水下表层沉积物中采集的59块样品进行孢粉分析,共鉴定72种陆生植物花粉和蕨类孢子,7种水生植物花粉和一些淡水藻类,用微型电子计算机进行了数据处理,计算花粉浓度及百分含量,并作多项式拟合,表示某些类型花粉和藻类与水深的关系.在此基础上对湖盆中心、边缘及河口等不同部位花粉总浓度、木本草本植物花粉及蕨类孢子分布的规律及数量特征等进行了讨论. | | 文摘来源 | |   | | << 更多相关文摘 |
