采用溶液培养法，在不同浓度Cd单一及Cd+Se复合污染下，对玉米体内叶绿素、脯氨酸、丙二醛，以及对超氧化物歧化酶、过氧化物酶、过氧化氢酶活性的动态变化进行测定。

Study on the activity of PAL、POD and SOD in the corn after inoculated pathogen showed that there were big differences between resistance and susceptible materials. The changs were more stabilization in resistance materials than in susceptible materials. There is a wave crest of activities in resistance materials, but no activity wave crest in the susceptible.

The result of factor analysis can provide the changes of relative precipitation and temperature variations. In trace elements, Cu, As, Zn, Pb and Ni were apparently enrichmented in soil layers and are sensitive to climatic changes. Carbon isotope is more sensitive to climatic changes than that of oxygen isotope in loess stratigraphy. The heavy mineral are varified in the loess stratigraphy, but their content differences between loess and palaeosol is little. Though the palynologic analyses results reveal that pollens and spores are fewer in the loess stratigraphy, they differ greatly in loess layer and palaeosol layer not only in species but also in types, i. e., the pollens and spores indicating warm and moist climate, such as Lles, Podocarpus, Polopydium, Pteris grerilliana Wall, Pterocarya and Juglans appear in palaeosol layers, while those indicating cold and dry climate such as Ephedra, Artemisia, Chinopodiaceae, Picea and Abies exist mainly in loess layers. The pollen content of broad-leaved tree mainly consisting of Pterocarya is up to 60% in palaeosol 〓, while the content of Ephedra is more than 50% in 〓 loess layer, showing that the environment differed greatly when 〓 and 〓 were formed.

当然，常量元素氧化物的组合因子分析结果可提供相对降水与相对温度在剖面的变化，因而来反映气候状况更为理想；微量元素中Cu、As、Zn、Pb与Ni在成土过程中富集明显，亦较好地反映了气候变化；稳定同位素中的碳同位素比氧同位素更能敏感记录气候的变化；研究区黄土地层中重矿物种类较多，但黄土层与古土壤层中含量差异不大；孢粉分析结果揭示，尽管研究区黄土层中孢粉总量相对较为贫乏，但黄土层与古土壤层中孢粉种属相差较大：在古土壤层内出现了指示相对暖湿环境的冬青属、罗汉松属、水龙骨属、林下凤尾蕨、枫杨、胡桃等植物孢粉，而黄土层中麻黄、藜科、蒿属及冷杉、云杉含量较高。

This is due to the highly polarizable oxide ions in the heavy metal glasses and the high polarizability of their cations, and this leads to a high polarizability of the whole molecule and easy distortions of the electron density in a strong electromagnetic field.

The experimental results indicated that these metal oxide catalysts had better catalytic activities to the methylene chloride gas at low concentration, and the catalytic activities increased with the increase of temperature,but decreased with the increase of inlet gas concentration. The CrO3/potsherd catalytic activity was better than V2O5/potsherd, and the CrO3/potsherd catalyst displayed higher activity at the relative low temperature.
