不同地域的阳光光谱分布特性

目的研究阳光的光谱能量分布特性。方法对高原、西北沙漠、热带海洋等3个地域200~800 nm波段的阳光进行光谱测量,分析不同地区、不同天气状况、不同扫描速度下的阳光光谱能量分布特性。结果高原地区阳光光谱中的紫外-可见波段的辐照强度明显比西北沙漠和热带海洋地区高,多云时200~800 nm波段的辐射总量与晴天相比降低1/4,200~400 nm的紫外波段的辐射总量仅为晴天时的54%。光谱测量仪的扫描速度对光谱测定结果基本无影响。结论研究获得的阳光紫外截止点、340 nm处的辐照强度、不同波段的辐照量,可为实验室光源暴露试验中的光源选择、光谱能量控制提供参考。     

The Upper and Lower Ecological Limits of Specific Metabolic Power of Different Organisms

It has been demonstrated that bioenergetic properties of plants (independence of productivity from size, proportionality between radial growth of woody plants and plant mass, etc.) and animals are not related to the presumed universal linear relationship between metabolic power and body mass to the power of 3/4. This relationship is not true for plants and endothermic animals. The observed bioenergetic characteristics of these organisms are explained by simple biological and physical laws, including the existence of the lower and upper limits of the specific metabolic power of living matter.     

我国31个省(市、自治区)的综合实力评价

选取具有代表性的9类共30个具体评价指标作为我国31个省（市、自治区）的综合实力评价的原始指标，运用因子多变量统计分析法对30个指标数据进行因子分析处理，采取主成分分析法提取公因子，并采取promox斜交旋转，得出6个公因子作为评价我国31个省（市、区）的综合实力的综合变量。计算得出我国各省（市、区）的综合得分。将计算的各省区市的综合得分从大到小排列，确定等级及分值区间。根据分类结果划分为6类地区，得出第Ⅰ、Ⅱ、Ⅲ类地区全部为东部地区，其综合实力得分位居全国前6位，它们依次是广东、江苏、上海、浙江、山东和北京；而第Ⅵ类地区中除海南属于东部地区之外，其余省市区都属于西部地区，其综合实力得分位居全国后7位且均为负值。它们依次是青海、宁夏．贵州、西藏、海南、甘肃和重庆。可见东西部地区社会经济发展的极度不平衡。     

秦山三期核电工程气象相关实验研究及其在选址评价中的应用

１９９５年９、１０月间在秦山三期核电厂址进行了气象相关实验，即在秦山一、二、三期进行低空风、温与地面风的同步观测，在三期厂址进行平衡球测扩散参数，风洞模拟实验测量建筑群对流场与扩散参数的影响．并探讨如何应用气象相关实验结果由已建厂址的气象数据来估算新建厂址年均扩散因子的方法与公式．     

蓄水、调水、发电，扼制生态环境恶化

蓄水是根本，调水是手段，发电是关键。植树造林和拦河筑坝建设水库电站以及沟渠塘蓄水，可以防止水土流失和水能浪费；调水可以解决横向和纵向水资源分布不平衡带来的问题；发电可以解决调水所需动力和全国缺电的问题。其经济效益约合２０００亿元，而且还能扼制生态环境的恶化，减少每年４６．６×１０４ｈｍ２土地的损失，缓解荆江大堤和黄河下游大堤越筑越高之危。     

Medieval Agroecosystems (9th–13th Centuries) in the Region of the Present-Day City of Glazov (Udmurt Republic)

Paleoethnobotanical materials and buried soils from the site of the ancient settlement of Idnakar and neighboring archaeological monuments were analyzed to reconstruct the agroecosystems of the 9th through the 13th centuries AD near the present-day city of Glazov. The results provided data on the main features of the agroecosystem structure and composition, climate, and agriculture in the Middle Ages.

Seasonal variations of Rn concentrations in the air of a tunnel located in Nagano city

The seasonal variation of 222Rn concentrations in the air of tunnels constructed during World War II at Nagano City has been investigated. The determination of 222Rn concentrations in tunnel air was performed using a solid-state nuclear track detector technique. The monthly radon concentrations changed smoothly, decreasing towards winter and increasing towards summer, and it was found that the concentrations strongly correlate with the temperature difference between the inside and the outside of the tunnel. In the innermost areas of the tunnel, the maximum concentration was observed in July, its value being about 6500 Bq m (-3). The concentrations of radon in the tunnel air decrease exponentially towards the openings of the tunnel, which indicates that the radon concentration in the tunnel is basically governed by diffusion and mixing of radon gas with air. These observations lead to the conclusion that the seasonal variation of the radon concentration in the tunnel air is mainly caused by a convection current due to a stack effect induced by the temperature difference between the tunnel air and the outside air.     

The economics of uranium demand

The major characteristics of the demand for uranium are identified, and a number of factors which determine the actual level of uranium requirements of the nuclear power industry are discussed. Since the role of inventories is central to the process of short-term price formation, by comparing projections of uranium production and apparent consumption, the relative level of total inventories is calculated and an assessment is made of its likely impact on the uranium market during the 1980s.     

Ecology of Nuclear Polyhedrosis Virus in Western Siberian Populations of the Gypsy Moth (<Emphasis Type="Italic">Lymantria dispar</Emphasis> L.)

The impact of the nuclear polyhedrosis virus on the population dynamics of the gypsy moth Lymantria dispar L. has been studied. The results have shown that polyhedrosis morbidity in the western Siberian population of the insect is relatively low, compared to that reported for North American and European populations. A possible cause of this situation is found in the high migration activity of moths in the Asian L. dispar populations, which allows the virus load on the biotope to remain relatively stable and insufficient for the initiation of mass viral diseases during population outbreaks.__________Translated from Ekologiya, No. 3, 2005, pp. 222–226.Original Russian Text Copyright © 2005 by Ilinykh.
