胶州湾的浮游藻类

浮游藻是水域有机物的生产者，作为食物链的基础环节，通常以它的种类及细胞数量来估价海洋水产资源的贫富，又因浮游藻随波逐流的生活方式，不同种类对海洋环境适应能力不同，具有不同的生物学特性，往往以此作为某些海洋环境因子的指标。

INFLUENCE OF THE KUROSHIO ON HYDROGRAPHY AND HYDROMETEOROLOGY IN THE EAST CHINA SEA NEAR-SHORE REGION

The aim of the study was l)to determine the relation between the Kuroshio meander and the intensity of the subtropic high pressure over the Pacific Ocean, and then to obtain statistical validity for the observational conclusion that the occurrence time of the Kuroshio meander leads the time of strengthened C-circulation of Europe by one or more years; 2) to develop a method to predict the occurrence time of flood or drought periods in the Changjiang River Valley from the occurrence time of the Kuroshio meander, since there is a close relation between the occurrence time of the drought or flood periods in the Changjiang River Valley and the occurrence time of the strong or weak periods of C- circulation of Europe; and 3) to develop a logical explanation verifiable by remote sensing technique and other means that the warm species phytoplanktons collected recently in the Jiaozhou Bay of Shandong Peninsula in China were carried there by a new warm current branch of the Kuroshio in the East China Sea.

济南水生植物的初步调查

一、引言济南位于山东地块的西部,约为北纬36°6′、东经117°之处,南面为一片丘陵地区,高度自数十米至三百余米不等,由石灰岩构成;东、北、西三面都是冲积平原,为近代的河流冲积物。本区的奥陶纪石灰岩,地下溶洞很多,第三纪和第四纪岩层疏松透水,地下水储藏量非常丰富,局部的自流水涌出地面而形成泉水,分布于全市各处。

确定胎儿肺成熟度的“JWL 法(景、王、伦法)”研究及青岛地区胎儿肺成熟度的确定

胎儿肺成熟度的确定,在围产医学高危妊娠中非常重要.胎儿出生时如肺尚未成熟,会发生呼吸困难综合症,是由于肺缺乏表面活性物质.此物质主要成分是卵磷脂(L)和鞘磷脂(S),通过胎儿呼吸进入孕妇羊水,可由此测定其含量.L/S 比值随妊娠进程会发生一定变化,肺成熟时的比值,即胎儿肺成熟临界 L/S 值.国外仅求得临床经验胎儿肺成熟临界 L/S 值≥2.0,但缺乏理论依据,更无肺成熟临界孕周值求得.为此,本文研究出一种既可确定胎儿肺成熟临界 L/S 值,又可进一步确定胎儿肺成熟临界孕周值的理论和方法,称为确定胎儿肺成熟度的“JWL 法”.并运用此“JWL 法”确定出青岛地区胎儿肺成熟临界 L/S 值≥2.06,临界孕周值≥35.6周.经过临床实例验证,证实此“JWL 法”的正确和有效.
