河外H2O超脉泽源及与其相关的分子谱线的观测和研究

自从在活动星系核NGC4945的视线方向上发现第一个河外H2O超脉泽源以来，迄今为止已发现了19个河外H2O超脉泽源，对与活动星系核成协和河外H2O超脉泽源及分子谱线的观测和研究是探测和研究活动星系核核区中央源，拱核气体和尘埃环性质的非常有效的工具，主要评述对河外H2O超脉泽源及与其相关分子谱线的搜索，观测和理论研究现状。     

蔚蓝色：中华文明的再度辉煌

在数千年的历史长河中，中华民族既有因亲近海洋，在航运及船舶制造、海上贸易、海洋渔业等方面谱写下了壮丽的篇章，创造出了灿烂的海洋文明的辉煌时期，也有过因疏远海洋、丧失了世界文明领先地位，沦为“东亚病夫”而遭受任人崭割的悲惨岁月。回顾过去，展望未来，开发海洋、经略海洋，必将带来中华文明的再度辉煌。     

ECOLOGICAL SERIES OF SOIL ANIMALS IN DARLIDAI MOUNTAIN

The ecological series of soil animals under the broad-leaved and pine mixed forest in Darlidai Mountainwas studied. Seven sample plots were selected according to different altitude gradients, which belong to different vegeta-tion types. By investigating and analyzing soil animals in every sample plot it is found that there are 45 groups and 1956individuals, which axe involved in 3 phylums, 7 classes, 16 orders, respectively. The altitude is a key factor which af-fects ecological series of soil animals. Both the groups and individuals of soil animals increase with altitude increasingunder certain conditions, which contrastes with ordinary cases, resulting from special micro-climate in studied area. Thegroups and individuls of soil animals are the most under the broad-leaved and pine forest on the top of the mountain, andthe least under Picea-Abies forest in the foot of the mountain.     

探索大洋锰结核矿的成因

海底锰结核是由英国人首先发现的。1873年2月18日,英国“挑战者”号考察船来到加那利群岛西南约300千米的海面进行海底取样调查。结果从海底捞上来几块像黑煤球的硬块。船上的几位科学家谁都没有见过这种“黑色的卵石块”。后来,这些“黑卵石块”送回英国。经过化验分析,才知道它不是化石,而是含有大量     

Heat-shock protein 70 expression in shrimp Fenneropenaeus chinensis during thermal and immune-challenged stress

Using western immunoblotting, we obtained heat-shock protein 70 (HSP70) induction data and distribution in different tissues from shrimp Fenneropenaeus chinensis during thermal and immune-challenged stresses. This is probably the first report of the effects of various stressors on the expression of HSP70 in shrimp.HSP70 was prominently induced in hepatopancreas and gills, but not in muscle, eyestalk and hemolymph, when the shrimp were exposed to heat shock and Vibrio anguillavium-challenged stresses. Cold shock and WSSV treatment had no significant effects on the levels of HSP70 expression in all tissues examined. HSP70 induction was greatest after 2 h exposure to heat shock stress, which was elevated after acute heat shock exposure of 10℃ above ambient temperature.     

戍海固边 任重道远

一场新的“蓝色圈地运动”正在世界各大洋、海域间展开，世界开始进入一个全面争夺瓜分海洋、开发利用海洋的新时期。     

印度洋与南亚、西亚沿海的海洋战略角逐（下）

美国对印度洋地区的掌控能力明显增强 在冷战时期，美国就在印度洋地区布有海外军事基地。美国印度洋基地群以迪戈加西亚基地为核心，辐射至印度洋沿岸各港口，特别是阿拉伯湾、波斯湾和红海地区。迪戈加西亚地处印度洋中心位置，是印度洋空中和海上交通枢纽，战略地位十分重要。自1971年美国海军从英军手中接管以来，     

Final report of IGCP Project 410 （1997-2002）——The Great Ordovician Biodiversification Event Department of Earth and Planetary Sciences, Macquarie University, North Ryde, NSW 2109, Australia. E-mail： bwebby@laurel.ocs.mq.edu.au

In 1997, IGCP Project No. 410 was established to appraise known records of Ordovician biotas, in order to evaluate one of the greatest-ever diversifications of life on Earth, between 489 and 443 million years ago. Data collection and analysis of biodiversity were coordinated through seven regional teams, and a global“clade” team.
