南疆博斯腾湖近12.OkaB.P.以来古气候与古水文状况的变化 总被引：6，自引：0，他引：6
对南疆博斯腾湖湖相沉积物多手段的综合研究，揭示了近12.0kaB.P.以来古气候与古水文状况的变化过程与特征。结果表明，其气候的演化特征具有明显的西风型环境演变特征。研究还发现气候于12.0ka、10.0ka、4.0ka和1.5kaB.P.存在显著的阶梯式增暖变干特征，其中暖峰主要出现于11.5—11.0ka、9.4ka、7.5—7.0ka、6.5—6.0ka、3.0ka和2.0kaB.P.，气候特征以干暖为主，湖泊水文特征总体表现为盐度增加、水位下降、湖面缩小；而冷峰主要出现于11.0—10.0ka、8.8ka、5.0—4.5ka、3.3ka和1.5kaB.P.，此时湖泊膨胀淡化，湖面上升。在7.0—5.0kaB.P.期间出现的相对暖湿环境特征可能是全新世大暖期最盛期暖湿气候特征的反映，可能与此时西南夏季风势力增强有关，湖泊水文状况明显变好。 相似文献

Haliphthoros philippinensis, a marine mastigomycete isolated from larvae of the jumbo tiger prawn Penaeus monodon, is described and illustrated as new. The fungus grew at a temperature range of 13.5 to 36.3℃, with the optimum of 29.3-34.5℃. Its growth occurred in peptone-yeast extract-glucose ( PYG ) broth containing 0.3-7% NaCl, with the optimum concentrations of 1 to 4%. At 8% or more NaCl concentrations, the growth was not observed. Its pH range for growth was 5 to 11. 相似文献

This pilot study attempts to demonstrate some underlying scanning electron microscopy themes of quartz grain surface textures. A variety of textural patterns and individual features are described for grains selected from various littoral environments. An attempt was made to differentiate samples on surface textures alone, but limitations of using this technique in sedimentological isolation were apparent. Statistical analysis of checklist data and photographic evidence revealed some of the more important feature combinations used in environmental diagnosis. The use of discriminant analysis provided quantitative sample separation. 相似文献

孢粉分析方法可以比较客观地反映古植被类型,而各植被类型只能在一定的气候指标范围内生长。本文根据这一基本原理,利用现代植被生长的基本气候指标和有关气象资料,对长江中下游地区7500—5000aB.P.的孢粉资料进行处理、转化,从而得出这一阶段每500年一个时间段的气候变化序列。研究结果表明,研究区在7500—5000aB.P.时间内,年平均温度偏暖于今日-0.1—1.5℃,最高温出现在6500—6000aB.P.,气温高于现在1.5℃。 相似文献

In this paper, the responses of the interaction system of R.C. gravity single-leg platform to seismic excitation are mainly analysed. A set of nonlinear equations for the interaction system are established by using the wave, one is the soil-structure interaction and the other is the fluid-structure interaction. The seismic response of the interaction system is analysed for the influence of the asymmetric structure, fluid action, etc. with the input of seismic SH waves in any direction. The numerical results are given for a simple example. 相似文献

By utilizing the denser upper-air observations from the Okinawa region and the Japanese islands during August 17-23, 1975, the structure of Typhoon 7507 formed in this area has been analysed. It has been indicated that the cyclonic tangential wind maximum occurred in the eastern sector of the typhoon and the strongest inflow occurred in the southern portion of the typhoon about 150 km away from the typhoon centre. There was a deep inflow layer below the 300 hPa level. The anticyclonic outflow was the strongest at 150 hPa and was located in the NE quadrant of the typhoon. The convergence mainly took place in the southern part of the typhoon, while the divergence occurred at the lower and middle levels in the northern sector of the typhoon. The pattern of vorticity and vertical motion field were characterized by the similar asymmetry. 相似文献

Among the specimens of Leptomysim (Crustacea, Mysidacea) collected from the northern part of the South China Sea by the Institute of Oceanology, Academia Siniea, Leptomysis xenops Tattersall and a closely related form were found by the authors. While studying on the morphological characteristics of these two species and their allies in the Tribe Leptomysini, we found that there are two natural groups of species previously ascribed to the genus Leptomysis G. O. Sars. The first group includes the type species of the genus and other 8 known species, viz. Leptomysis gracilis (G. O. Sars. 1864), L. lingvura (G. O. Sars, 1866), L. sardica G. O. Sars, 1877, L. mediterranea G O. Sars, 1877, L. capensis Illig, 1906. L. megalops Zimmer, 1915, L. australiensis Tattersall, 1927. L. peresi Bacescu, 1966, and L. burgii Bacescu, 1966, of which the cornea of the compound eye is normal——with numerous small facelets of equal size, the telson is usually armed with 2 or 3 pairs of larger apical spines; while in species of the second group, in which L. apiops apgops G. O. Sars, 1877, L. apiops banyulensis Bacescu, 1966, L. xenops Tattersall. 1922 and the new species described in this paper are included, the cornea consists of two parts, the anterior part with small and normal faeelets, but of the posterior part, the facelets are very unique, being larger and much elong ted to form a "bauquet"-shaped process. These differences showed that the two groups are heterogenous and belongs actually to two distinct genera. In order to receive the last 4 forms, a new genus, Paraleptomysis gen. nov. is established, and an account of the new genus and Chinese species is given in this paper. The type materials of the new species, P. sinensis sp. nov. are kept in the Institute of Oceanology, Academia Sinica (Qingdao). 相似文献

This paper, the second part of further analyses of the structure of the typhoon, mainly discusses the distributions of temperature and moisture fields of typhoon No. 7507. The result has shown that the typhoon developed from the warm-core disturbance. The height of maximum warming is highest (300 to 250 hPa) during the mature stage. There is a dry layer capping the typhoon during the initial stage. Once the typhoon rapidly developed, the dry layer was destroyed. A deep saturation layer eventually occurred in the central region of the typhoon. Meanwhile, the dry air from the China main continuously intruded into the outer region in the western and northwestern parts of the typhoon.The initial eyewall of the typhoon sloped outward with increasing height, and then became nearly vertical below 12 km level. This was closely associated with convective activity. The convective instability had been mostly released during the growing stage of the typhoon and stratification rapidly tended to moist neutralization. 相似文献

真丝藻属Eudesme是J.Agandh于1880年(J.Agardh 1880，p.29)建立的。其主要特征为：次生基部由直立初生中央轴及假根状丝体组成；初生中央轴由几个丝体束构成；假根状丝体则由中央丝体的基部产生；中央轴多管状，合轴分枝，由纵向排列的丝体组成，排列比较疏松；内皮层细胞从中央轴横向长出，稍网状排列；同化丝由内皮层末端细胞产生，不分枝，有密集的载色体；毛透明，从生长点或皮层丝体的基部产生；单室孢子囊无柄或在皮层丝体上有柄。
中国真丝藻，仅Lu Baoren和C.K. Tseng(1983)在“Common Seaweeds of China”中对Eudesme virescens(Cam.)J.Ag.作过描述外，未见其他更详细的报道。经过最近几年本文作者的研究发现中国真丝藻共有4种，除了Eudesme virescens(Cam.)J.Ag.外，另外还有黄海真丝藻Eudesme huanghaiensis Ding et Lu、青岛真丝藻 Eudesme qingdaoensis Ding et Lu和山东真丝藻Eudesme shandongensis Ding et Lu3种。 相似文献
