A Preliminary Study of Quantitative Distribution of Benthic Animals in the East China Sea Continental Shelf and Its Adiacent Waters

In October and November of 1977 and September and October of 1978,a quantitative survey of benthic animals was conducted in the East China Sea Continental Shelf and its adjacent waters(26°00'-34°00'N,124°00'-129°00'E,water depth 39-1550m),where 307 stations were dredged and 1200 samples collected.     

海洋走航式单边连续观测地震折射波Δt解释方法--1种新的浅层折射单支时距曲线解释方法

在浅层工程折射地震测量中 ,通常采用相遇观测系统采集数据和相应的解释方法进行解释 ;对于单边观测采集方法由于与其相应的解释方法较少而少被采用。本文提出 1种方法简单、精度可靠、可直接利用同一点相邻 2排列 2次观测的初至折射时间并适合于海洋走航式单边连续观测系统的折射初至资料解释方法。其精度基本与同观测段的采用相遇观测的差异时距方法解释的精度十分接近。该方法即适合于人工解释又适合于计算机自动解释。     

银川盆地中更新世以来的孢粉记录及古气候研究

银川盆地中更新世以来的孢粉记录及据此所重建的古气候参数，揭示了该区中更新世以来的古气候演变特征，其演变经过了温湿→凉湿→温和→冷湿→温干→凉较湿→冷湿→温干→凉润→温较干→温干的变化，并与新疆地区，黄土高原以及深海δ^18O曲线进行了对比，结果表明，各地的古环境变化大致同步，该区由于位置靠西，邻近沙漠，最近地质历史时期的区域性干旱特色明显。

FURTHER ANALYSES OF THE STRUCTURE OF TYPHOON NO.7507 Ⅰ. KINEMATICAL FIELDS

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.

超声辐射对牟氏角毛藻的生物效应研究

设计了一个超声频率，超声功率和辐射时间3因素4水平的正交实验，研究超声辐射对牟氏角毛藻的生物效应。实验结果表明，超声频率对牟氏角毛藻的生物效应显著，而超声功率的辐射时间的影响相对较小，在正交实验所确定的最佳超声辐射条件下，牟氏角毛藻生长速率常数最高可达0．348d^-1，是对照组的1．78倍，并脂肪酸不饱和度最高可达68．4％，比对照组提高5．2％，主要不饱和脂肪酸的百分含量均可得到不同程度的提高。     

A COMPARATIVE STUDY OF 1982-1983 EL NIÑO EVENT

The 1982-1983 El Niño event is examined in comparison with the other El Niño events in 1949-1983. The relationships of subtropical high to the sea surface temperature (SST) show the important influence of the atter, which vaired with the characters of El Niño events.
