威远震旦系天然气与油气生运聚

根据威远震旦系气藏天然气组成、同位素特征、储层包裹体的对比研究 ,我们认为该气藏的天然气主要来源于下寒武统筇竹寺组泥岩 ,其天然气主要是干酪根裂解气 ,次为油的裂解气。威远震旦系气藏是喜山期形成的 ,威远的天然气无论是干酪根裂解气还是油裂解气都由北面古构造聚集的干酪根裂解气和油裂解气转移而来 ,威远构造之所以能形成工业聚集的重要原因就是威远构造的形成与北面古构造的消失的良好匹配关系     

Kinetics of hydrogen peroxide-sulfur (IV) reaction in atmospheric precipitation

The kinetics of the reaction of dissolved S(IV) with H2O2 was studied on 59 precipitation samples collected in Southwestern China, during the period of June 1988 to October 1989, from which the oxidation rates of the reaction were measured. The extent of reaction was followed by continuous amperometric measurement of the concentrations of the reagents. The two systems (i. e. rainwater and purified water) have been studied with the same methodology under identical reaction conditions (e. g. reagent concentrations, ionic strength and temperature). The kinetics was studied in no buffer solutions. The effect of formaldehyde on the reaction has also been studied, including kinetic studies in laboratory and model calculations, and it is indicated that formaldehyde with typical atmospheric concentration exerts no influence on the reaction of dissolved S(IV) with H2O2. In addition, the activation energy of the reaction was also measured in purified water as reaction medium for temperature range 0-50℃ at pH 4.0

二氧化硫对大鼠肺泡巨噬细胞DNA的损伤作用

运用单细胞凝胶电泳技术(又称彗星实验)研究了SO2动式吸入对雄性Wistar大鼠肺泡巨噬细胞DNA的损伤作用。结果表明，在SO2浓度为28．6，57．3，114．4ms／m^3的动式吸入染毒条件下，雄性大鼠肺泡巨噬细胞DNA拖尾长度分别为7．59，12．39，21．22μm，表明SO2可引起大鼠肺泡巨噬细胞DNA损伤，且随SO2吸入浓度的增加而加剧，呈明确的剂量效应关系，这意味着SO2具有引起哺乳动物肺泡巨噬细胞DNA突变的潜在危险，会造成机体的非特异性吞噬功能和抗肿瘤免疫监视作用的损伤。

Numerous experiments for the impact of warming climate on the phenology and grain yield of winter wheat

Based on the environmental and crop data at Zhenjiang City, in Jiangsu Province, middle east of China, the growing process of winter wheat was simulated by CERES-Wheat model assuming the daily average temperature is 1℃ to 2℃ higher than at the present, which are mostly possible for the change of climate because of enrichment of greenhouse gases in the atmosphere. The simulation results show that warming climate can promote development rate and shorten phenological stages of wheat, and the grain yield will be higher than present. Its impact on the kernel weight and grains per square meter were different for the plantings of various sowing dates. The results of this study suggest that substantial changes in agricultural production and management practices are needed to respond to the climatic changes expected to take place in China.

利用三维欧拉型污染物输送模式，气相过程分别采用查表法处理和直接耦合区域性光化学模式（ROS），对1992年硫氧化物输送、沉降量与实测值进行了模拟比较。结果表明，查表法可以节省大量的计算时间，所用时间约为直接耦合化学模式的1／7，查表法处理气相过程能够较好地反映SO2和SO4^2-浓度分布与沉降状况，与直接耦合化学模式具有同样的精度和较好的可信度。
