The pressure ridge partly moved to southeast, it led to the cold air stream more moved to southeast, and the strong cold wave broke out. The water vapor from Caspian sea to Bslkhash lake accumulated at the upper of north Xinjiang, and it provided the water vapor condition for the cold wave. The ECMWF numerical forecast product accurately predicted the evolution trend of circulation (the position, intensity, path and speed of ground surface cold high pressure) of height field in this cold wave process. The predicted temperature at 850 hPa had good corresponding relation with the actual lowest temperature.

The excited-state intramolecular proton transfer tautomerism reaction of 6-methyl-4-hydroxy pyri-midine monomers and dimmers was investigated by the ab initio method with the self-consistent reaction field with Tomas's polarized continuum mode and CIS theories at HF level on the basis of 6-311+G* and 6-31G basis set. By studying the potential energy surface, it was found that the monomer's ground-state proton transfer process together with the excited-state proton transfer process is a molecular system of four energy level, but dimmers were not, which can be used to explain the fact that UV-visible absorption and fluorescence spectra of monomer and dimers all corresponded to quinoid.
采用 ab initio HF理论的组态相关CIS方法和连续溶剂模型PCM,分别在6-311+G*和6-31G水平上研究了6-甲基-4-羟基嘧啶单体及二聚体激发态质子转移的异构化反应;对其反应势能面的研究发现,单体基态和激发态的异构化反应一起可以形成四能级的分子电子体系,而二聚体的却不能,由此解释了单体和二聚体的紫外吸收光谱和荧光发射光谱均对应于酮式构型的原因。

In this paper, as a case of Karamay, we have studied on space-time changement of soil quality in oasis of arid area. We measured quality for different land use types and years in same type by combinativing field sampling for Karamay in Xinjiang and analysis in laboratory, which is directed by former theory of soil quality. Then we did integrated evaluation of soil quality for different land use types, and had drew some conclusions as followed: In four land use types, the soil bulk density of layers(0~15cm) for farmland and tree land is bigger than the other land use types.The organic matter of every layer in manpower Tamarix Bulrush land is bigger; organic matter of Tamarix Bulrush land release efficiency nitrogen which result ration of C/N is higher; total nitrogen of all layers in farmland variety great as being effected by mass use of nitrogen in agriculture; deadwood and defoliation of tree、shrub and bulrush pooled in 5cm layer to result that quick nitrogen is the biggest among all layers. The total salt of nature shrub tree land for every layer being bigger than farmland explain that nature shrub thee land strongly stand salt and farmland for basification in this area; that the nutrient of face layer is bigger than the ground layer may be explained by that vegetation gather nutrient to be stored in deadwood and defoliation.
本文对以克拉玛依为例,对干旱区绿洲土壤质量的时间空间变化进行研究,在有关土壤质量的研究理论指导下,通过田间调查取样和室内分析相结合的方法,对新疆克拉玛依市农业开发区的不同土地利用方式及同一土地利用方式下不同利用年限土样土壤理化性质进行测定,从而对新垦绿洲不同土地利用类型土壤质量进行综合评价,结果如下:四种土地利用方式中,农地、乔木林地表层(0-15cm)土壤容重较大;各土层人工柽柳芦苇地的土壤有机质含量均较大;柽柳芦苇地的有机质在矿化过程中所释放出有效氮,导致柽柳芦苇地的C/N比例较高;受到农业耕作使用大量氮肥的影响,农地各土层全氮含量变异较明显;乔木、灌木及芦苇的枯枝落叶主要集中在5cm范围之内,导致几种土地利用方式类型下该层土壤速效氮最大;天然灌木林地的土壤总盐在各层均较大,其次是农地,说明天然灌木林地的高耐盐能力,以及该区农业生产用地的土壤盐碱化程度较重。
