In this paper, petrography, mineralogy and geochemistry were jointly used to determine the origin of the mafic enclaves and their relationship with the host granitoids of the Kan granite-gneiss complex. This study also provides new information on crust-mantle interactions. The mafic enclaves of the Kan vary in shape and size and have intermediate chemical compositions. The diagrams used show a number of similarities in the major elements (and often in the trace elements) between the mafic enclaves and the host granitoids. Geochemical show that the Kan rock are metaluminous, enriched in silica, medium to high-K calc-alkaline I-type granite. The similarities reflect a mixing of basic and acid magma. Mafic enclaves have a typical magmatic structure, which is characterized by magma mixing. The genesis of these rocks is associated with the context of subduction. They result from the mixing of a mafic magma originating from the mantle and linked to subduction, and a granitic magma (type I granite) that arises from the partial melting of the crust.展开更多

[Method] The leaves and axillary buds of Atropa belladonna L. were as the explants,the influences of different ratios of 6-BA and NAA in the medium on the adventitious bud differentiation and the sensibility of leaf on Kan were studied. [Result] MS＋4.5 mg/L 6-BA＋0.2 mg/L NAA was the optimum medium of leaf adventitious bud differentiation,and the differentiation ratio of adventitious bud reached 100%. The number of adventitious bud differentiation on 1. 0 cm ×1. 0 cm leaf block averagely reached 5.85. MS＋3.0 mg/L 6-BA＋0.1 mg/L NAA was the optimum medium of axillary bud adventitious bud differentiation,and the differentiation ratio of adventitious bud reached 100%. The average number of adventitious bud differentiation in every axillary bud was during 4-8. The optimum screening concentration for genetic transformation of Atropa belladonna L. leaf was 400.0 mg/L of Kan. [Conclusion] The research laid the foundation for the rapid propagation of Atropa belladonna L. aseptic seedling and the genetic transformation based on the leaf disc cocultivation.展开更多

This type of sub-complex appears naturally in several topological and algebraic contexts. In this note we prove that regularity of a partial group implies that the Kan extension condition is satisfied on its nerve in dimensions greater than one, and in dimension one a weaker version of the extension condition holds.展开更多
