台湾暖流起源的研究

根据台湾东北海域的水文资料分析,作者对台湾暖流起源提出以下看法:台湾暖流起源于黑潮分支和台湾暖水,黑潮分支为主要源泉。台湾暖流的深层水完全来自黑潮分支的深层水,不具有暖流性质,而其上层水是由黑潮分支的上层水和台湾暖水组成。由于台湾暖水有明显的季节变化,与此相应,台湾暖流也发生相应的变化。

溴素的有机化学──Ⅴ.溴代脂肪酸—2,3,5,6—四溴—1,4—苯二酯的合成

以1，4—苯二酚和不同的短链脂肪酸为基本原料，经溴代、加成、形成酰卤和酰化等反应，合成了六种新的溴化脂肪酸—2，3，5，6—四溴—1，4—苯二酯。通过对产物的碳、氢、溴等元素的定量分析，以及红外吸收光谱和氢核磁共振谱的研究，验证了化合物的结构。     

柴达木盆地昆特依盐湖的地球化学演化与古气候变化

１９９０年用铀系年代学及古地磁对昆特依盐湖沉积物进行年代测定，探讨该湖区地球化学演化与古气候变化关系。结果表明，该区最老的盐层形成于早更新世晚期（大于７３０ｋａ），大量的盐类沉积则始于３００ｋａ左右；盐湖沉积物中元素含量变化主要受古盐度、矿物、类质同象和吸附控制；沉积物水溶Ｆ／Ｃｌ比值与古盐度成反比关系；该湖２０００ｋａ以来的古环境演变：盐层形成于干冷、偏酸性的氧化环境，泥岩层形成于湿暖、偏碱性的     

Characteristic analysis on oxygen isotopic tracer in the East China Sea and waters to east of the Ryūkyū-guntō

Samples of O isotopic tracer were mlleMed at Sections P₃,P₂₅,P_cM-t/2-E and P_CM-1/2.w in both the Fast China Sea and the area to the east of the Ryūkyū-gunto during October-November,1991.Analytical results of the δ¹⁸O are as follows: (1) In the Kuroshio area,the δ¹⁸O isolines are almost parallel to the 200 m isobath.The value of δ¹⁸O is negative and reaches minimum mt the main axis of the Kuroshio,and increases on both sides.(2) In the Taiwan Warm Current (TWC) area there is a high δ¹⁸O tongue extending to the northeast.(3) In the area near the coast,the distribution of δ¹⁸O isoline shows that the Changjiang River runoff diffuses seaward and the land-ocean isotopic effect from the nearshore to the offshore.(4) The values of δ¹⁸O are from -1.0×10^-3 to -0.5×10^-3 in the shelf.(5) There is a low mre of δ¹⁸O value(<-1.6×10^-3) at the 600 m layer in the Kuroshio area,which is quite in accord with the existence of a low salinity mre (S G 34.30) between the 600 and 800 m layers in the same area.Finally,the mrrelations of the δ¹⁸O with the salinity and temperature,the upwelling and so on are discussed.     

The study of the Kuroshio in the East China Sea and the currents east of the Ryukyu Islands

In this study, the inverse method is used to compute the Kuroshio in the East China Sea and southeast of Kyushu and the currents east of the Ryukyu Islands, on the basis of hydrographic data obtained during September-October, 1987 by R/V Chofu Maru. The results show that: (1)A part of the Taiwan Warm Current has a tendency to converge to the shelf break; (2) the Kuroshio flows across the section C3 (PN) with a reduced current width, and the velocity of the Kuroshio at the section C3 increases and its maximum current speed is about 158 cm/s, and its volume transport here is about 26×106m3/s; (3) the Kuroshio has two current cores at the sections C3 (PN) and B2 (at the Tokara Strait); (4) the currents east of the Ryukyu Islands are found to flow northward over the Ryukyu Trench during September-October, 1987. The velocities of the currents are not strong throughout the depths. At the section C2 east of the Ryukyu Islands, the maximum current speed is at the 699 m levei and its magnitude is 25 cm/s, and i     

广东三水盆地晚自垩世—始新世古地磁研究及构造意义

对广东三水盆地上白垩统三水组、大　山组、古新统莘庄组及始新统　心组、宝月组的系统的古地磁研究结果表明：（１）旋转运动是该区构造运动的主要形式，顺时针旋转盆地拉张发育，这时针旋转盆地挤压衰亡，发育的程度与旋转角度有关；（２）始新世该区旋转方向由顺时针旋转变为道时针旋转，对应于太平洋－库拉板块对欧亚板块作用方向的改变，说明三水盆地的形成发育与太平洋－库拉板块对欧亚板块的作用密切相关；（３）三水盆地所在的华南地块从晚白垩世至始新世在纬向上不存在明显的运动，一直停留在略低于现今纬度的位置上。     

环太湖河道污染物负荷量的初步研究

根据１９８７－１９８８年环太湖河道水质，水量实测资料以及环湖主要河道的流量和水质的历史资料，结合平原水网地区的水情特征，提出了环太湖河道污染物负荷量的计算方法，并分析探讨了不同设计水情下环太湖河道污染物负荷量及其时空变化。结果表明，污染物负荷量与水情关系密切，枯水年的河道入湖污染物负荷量大于丰水年。环湖２２条主要河道的入湖污染物负荷量占全部河道入湖总量的７２％－９１％，且不同污染物入湖负荷量的分布     

台湾海峡上升流区底栖生物数量动态的初步研究

不同季节底梄生物数量的动态由其组成种的种群特点所决定。在一些生命周期短(一年左右)、生长速度快(新生个体当年可以长成)的种处于优势的情况下,生物数量的季节变化就比较显著;而生命周期长、其种群由多个年龄组的个体构成的种占优势的情况下，一年之中种群数量就相对稳定。另一方面,底栖生物数量的急剧改变又决定于经济种的捕食活动和优势种的生物学过程。台湾海峡系经济鱼、虾类的集中分布区,尤以上升流区范围内的集群最密集。为了便于深入研究上升流与经济鱼、虾类资源的关系,本文着重探讨上升流范围内底栖生物数量的动态特点。
