干法加氨脱除SO2中的温度效应

研究了在ＮＨ３参与下，干法脱除ＳＯ２中的温度效应，实验结果表明，在ＳＯ２与ＮＨ３的热化学反应中，反应程度随温度上升呈线性下降，然而，在脉冲电晕条件下，ＳＯ２脱率却随温度上升呈现非线性变化，通过测定不同温度下的产物组成，揭示了在脉８冲电晕放电条件，干法脱除ＳＯ２存在两条平反应途径；（１）先成盐后氧化；（２）先氧化后成盐，在较高温度下反应主要按第（２）条途径进行。     

Analysis and improving ways for water condition in winter wheat field of dryland in subhumid areas of the loess plateau

Based on the soil moisture data from the locating experiments from 1986-1990, and using the water balance method, the water supply and demand state in the field of winter wheat, and the ways for improving water condition in dryland of subhumid by dry area of the Loess Plateau were studied. The results suggested that a low precipitation satisfying ratio of 42.9%-58.8% appears in the growing period of winter wheat, and the yield, to a great extent depends on the water that was stored in deep soil layer in the previous rainy season. The filed trial results showed that tillage in the summer fallow period,straw cover, soil moisture regulation with adequate fertilization, crop rotation and proper croppingsystem could be the efficient ways for improving the water condition,and for the exploitation and utilization of natural water resources(both precipitation and soil water) in the winter wheat field of dryland.     

黄河上游西线调水工程对调出区气候影响的初步分析

在分析南水北调西线工程水量调出区气候特征的基础上,采用定性与定量相结合的方法,重点分析了调水工程对库区与坝址下游临近河段局地气候的影响,以及调水对引水坝址下游“干旱河谷”区的可能影响,并对干旱河谷的分布及其成因进行了较深入的分析。结果表明:调水对库区气候影响不大;对坝址下游临近地区的气温、降水等将不会造成明显的影响;对干旱河谷区的局地气候虽有影响,但很微弱。

详细介绍了唐钢３＃高炉干法煤气净化系统。该系统与湿式高炉煤气净化系统相比，提高了煤气质量，节能效果显著，具有广泛的推广使用价值。     

渗水地膜与旱地农业

经过对地膜物料结构的深入研究，提出了单向渗水原理，设计并发明了渗水地膜。渗水地膜具有保温、调温、渗水、保水、微通气等多种功能，可使半干旱地区发生频率为７０％左右、年累计量为１００～１５０ｍｍ的小雨量资源得到开发利用。旱地试验表明：渗水地膜覆盖的粮食作物比常规地膜覆盖的增产１５７％～３８３％，比无覆盖的增产１倍以上。     

废干电池浸出的试验研究

以锌碳电池和碱性锌锰电池为实验对象，通过固体废物浸出毒性试验，探讨废电池在不同破坏程度、不同pH值和不同浸取级数条件下的浸出规律。试验发现，锌碳电池中Pb、Cd、zn、Mn浸出浓度相对较高，碱性锌锰电池中Cu、As、Hg浸出浓度较高。对于锌碳电池，中性浸取剂和酸性浸聚剂影响不大，而对于碱性锌锰电池，酸性浸取剂条件下浸浓度反而较低。锌碳电池和碱性锌锰电池都是在完全破坏条件下浸出浓度高。在实际中，电池外壳腐蚀是一个缓慢的过程。     

Destruction of Forests and Wildlife in the Kashmir Wilderness

Much of the forest wealth on the plains and in the hilly areas of India has been foolishly destroyed, and the rich heritage of wildlife has been slaughtered mostly for only temporary gain. The wanton axing of the larger indigenous trees and the uprooting of other floristic elements in the hills and on the lower slopes of the mountains, gradually impoverishes them, and may be followed by erosion that ultimately leaves the slopes barren. These alarming threats to the chir (Pinus roxburghii) and fir (Abies pindrow) forests of Kashmir will have disastrous consequences. Once densely-forested, the mountain slopes in Kashmir have become largely naked through too-heavy tapping and cutting of the trees; with concomitant landslides, frequent floods, and loss of fertile topsoil. Unfortunately, the people living in the areas of the chir and fir trees, do not play a proper part in their protection, and the last two decades have witnessed, year by year, the rapid march of urbanization and manifold destructive activities which have taken a heavy toll on these precious species. Urgent conservation measures are essential to preserve these endangered trees in Kashmir.     

The community vs. the market and the state: Forest use inUttarakhand in the Indian Himalayas

Most writers on resource management presume that local populations, if they act in their self-interest, seldom conserve or protect natural resources without external intervention or privatization. Using the example of forest management by villagers in the Indian Himalayas, this paper argues that rural populations can often use resources sustainably and successfully, even under assumptions of self-interested rationality. Under a set of specified social and environmental conditions, conditions that prevail in large areas of the Himalayas and may also exist in other mountain regions, community institutions are more efficient in managing resources than either private individuals or the central government. In advancing this argument, the paper undermines the often dogmatic belief in the universal superiority of private forms of ownership and management.
