为了研究等离子爆破技术结合切缝管和预切槽技术的定向致裂效果，开展等离子体电脉冲定向致裂试验，探究不同切缝管切缝形状和不同预切槽间距下等离子体爆破定向致裂机理和定向断裂效果，对比分析不同定向形式作用下等离子体爆破岩石定向断裂贯通效果.结果表明，与正楔形切缝管和平切形切缝管相比，切缝管岩石试件中倒楔形结构中产生的应力峰值最大，聚能效果最显著，其定向贯通岩石效果更显著.预切槽岩石的电爆聚能致裂效果随着钻孔切槽间距的增加而减小.切槽间距为40 mm时，预切槽岩石试件等离子体电脉冲的聚能效果优异，产生定向裂纹的效果明显优于切槽间距为50 mm和60 mm的预切槽岩石试件.同时，预切槽定向形式的等离子体爆破定向致裂效果相对于切缝管定向致裂效果更为显著.

Chemical analysis of groundwater in petroliferous basins can be an effective way to determine the regional hydrogeological regime and to evaluate the preservation conditions of hydrocarbons. This paper presents the hydrochemical distribution of both individual aquifers and different structural units within the Palaeogene strata of the Gaoyou subbasin in the North Jiangsu Basin, east China. The results show that the salinity of the Palaeogene aquifers in the Gaoyou subbasin displays a systematic increase from the central deep depression to the periphery areas, and shows a reverse trend as the burial depth increases. Salinity maps of individual aquifers suggest that formation water in the deep layers at the centre of the study area probably retains original features of fresh lake water. Geofluids near the central deep depression of the Gaoyou subbasin migrate vertically through the Zhenwu and Hanliu faults, while those of the northern slope belt mainly flow laterally through aquifers. Both low and high salinity formation water can be found in the hydrocarbon producing areas. The low salinity zones commonly affected by infiltrated meteoric water are unfavourable conditions for the preservation of trapped hydrocarbons.

由大豆疫霉菌引起的大豆疫霉根腐病是严重影响大豆生产的毁灭性病害之一。防治该病经济有效的方法是抗病育种,而抗性资源筛选又是抗病育种的基础。采用下胚轴伤口接种法,用黑龙江省大豆疫霉菌的1号优势生理小种对来自黑龙江、吉林、河南、内蒙古、辽宁、湖北、四川、河北、陕西、中国农业科学院的536份栽培大豆材料(其中农家品种280份、其它大豆品种256份)进行抗性鉴定,抗病的152份,占28.3%,中间类型的135份,占25.2%,感病的249份,占46.5%。280份农家品种中,抗病的有89份,占农家品种的32%,这说明农家大豆品种资源抗性比例较高。种皮色或种脐色为黄色或褐色的材料中抗性种质较多。

Catassembly is a new concept in molecular assembly that is analogous to catalysis in chemical synthesis. However, for most molecular-assembled processes, the catassembler contributions are rather inconspicuous due to the low activation barriers. As a result, few systems dealing with the catassembly are available until now. In this paper, we report that naphthalene diimide coordination networks are formed under the catassembly of lone-pair-bearing catassemblers(e.g., N,N-dimethylacetamide, N-methylpyrrolidin-2-one). During such molecular assembly, a stable transition state between the electron-deficient naphthalene diimide tectons and catassemblers via the less common lone pair-π interactions was observed, which is supposed to play the key role in the enhancement of coordination abilities of organic tectons and thus formation of the final coordination networks.
