The firing activities of Hindmarsh-Rose (HR) neurons are studied by means of numerical simulation and bifurcation analysis. A single HR neuron exhibits various firing pattes, such as quiescent state, periodic spiking, periodic bursting and chaos, when the exteal current input is changed. The fast/slow dynamical analysis is applied to explore the dynamical behaviour of the HR model. The complete synchronization of two coupled identical HR neurons with electrical coupling mimicking gap junctions can be realized in certain ranges of the coupling strength, whenever each individual neuron shows quiescency, periodic firing and chaos. The criteria for complete synchronization are analysed theoretically, and the corresponding numericaI simulation is presented as well. The persistence of the interspike intervals bifurcation structure of the coupled HR neuronal system under electrical coupling is also discussed.

RNA干涉(RNA interference,RNAi)是由双链RNA(dsRNA)引起的特异性序列的转录后基因沉默。大豆种子的储藏蛋白基因的表达调控主要发生在转录水平和转录后水平上。提高11S球蛋白的含量或降低7S球蛋白的含量可改善大豆蛋白的功能特征和营养品质,却不会改变总蛋白质和脂肪的含量。因此,本实验以p-伴大豆球蛋白α亚基基因为靶基因设计RNA干扰载体,并将其转化大豆,探究此基因对提高种子
