Under the synchronous propulsion of new four modernizations and the coordinated development of urban and rural areas,the important issues we face are to protect the Chinese traditional villages,inherit the agricultural heritage,and develop the farming culture resources. There are 60 Chinese traditional villages in the Wuling Mountain area. This article introduces the Chinese traditional villages in the area,analyzes its Chinese traditional village protection and beautiful village construction,and puts forward corresponding recommendations.展开更多

Besides the statistics of its vigor of germination, the M1 root-tip cells of these broad beans were systematically analyzed on their changes in mitotic percentage, morphology and behavior of chromosomes, along with the structure o f cytoskeletons, including microtubule and intermediate filament. Based on all results of these studies, our opinions have been expressed in the report on the mechanism of low-energy N+ beams effecting on higher dicotyledons such as broad beau.展开更多

For checkingthe consistency of the Java Beaus semantic constraints with its implementation,this paper proposes a formal Java Beaus Description Language (JBDL) to specifycomponent semantic constraints. The JBDL logic is based on many sorted firstorder logic and Computation Tree Logic (CTL), with extension of some facilities inspecifying object oriented features. A framework for dynamic checking Java Beaussemantic constraines in JBDL form is described in this paper and some experimentalresults are showed by examples.展开更多

Saxa). The coarse studies of mRNA accumulation of the PvSR1 has been studied in this plant against virus infection and various abiotic sacsses. Northern blot analysis revealed that the gene expression of PvSR1 was greatly enhanced in the leaf tissue by AIMV (alfalfa mosaic vims) infection, wounding, heat shock, UV, drought and salt stress. The PvSR1 transcripts could also be increased by the exogenous inducing fartors such as salicylic acid and H2O2. The Precise biological roles of PvSR1 is unknown, but the expression of PvSR1 genes in various form of stress suggest that PvSR1 may play an important role during the strees, in maintaining cellular integrity by forming strong linkages with the cell wall.展开更多
