In the present study, efficient identification methods for the main varieties of cowpea (Vigna unguiculata W.) and cauliflower (Brassica oleracea L.) in south of China, especially in zhejiang province, were investigated by using seven cowpea varieties (variety 1, Zhijiangtechang80;variety2, Zhijiangtechang90;variety3, Qiujiang512;variety4, Zhijiang228-2;variety5, Huajiang24;variety6, Yangjiang40;and variety7, Xingaochan8) and five cauliflower varieties (variety A, Longfenteda50tian;variety B, Yidaijinguang80tian;variety C, RuixuetedalOOtian;variety D, Qiuwang80tian;and variety E, Tezao50tian). The application of seed shape, seedling shape, rapid chemical identification and electrophoresis was performed, the main results were as follows.
为开展南方特别是浙江省主要蔬菜作物种子高效快速鉴定技术研究，本试验以七个豇豆品种品种1(之豇特长80，品种2(之豇特长90)，品种3(秋豇512)，品种4(之豇228—2)，品种5(华豇24号)，品种6(扬豇40号)，品种7和五个花椰菜品种品种A(龙峰特大50天，品种B(一代金光80天)，品种C(瑞雪特大100天)，品种D(秋王80天)，品种E(特早50天)为材料，从种子形态、幼苗形态、快速化学和电泳鉴定等方面对豇豆和花椰菜品种鉴定进行了研究，特别是对乳酸—聚丙烯酰胺凝胶电泳在这两种蔬菜品种鉴定上的可行性进行了研究。

A it is predominantly derived from the initial variety or from a variety which itself was predominantly derived from the initial variety, while retaining the expression of essential characteristics that result from the genotype or combination of genotypes of the initial variety; an essentially derived variety may have been obtained by the selection of a natural or induced mutant or of a somaclonal variant, by the selection of a variant individual from plants of the initial variety, by backcrossing, by a transformation by genetic engineering, or by any other similar method
一个品种主要由原始品种演化而来，或主要由原始品种的实质性派生品种演化而来，同时保留了来自原始品种基因型或基因型组合的基本特征的表达；一个实质性派生品种可能通过选择自然变异或诱变或体细胞无性变异、原始品种植株的个体变异的选择、回交、基因工程的改造或任何其它类似方法而获得。

The definition and stability criterion of resonant operating points in a CPT system have been described. A Poincarémapping model has been built up and its Jacobian matrix has been derived with the implicit function derivative rule and chain rule. Then the stability of the fixed points can be determined according to the eigenvalues of the the Jacobian matrix. It has been used to study an example push-pull CPT system with three resonant operating points.
文中给出了CPT系统中谐振点的定义及判断条件，建立了系统的庞加莱映射模型，并根据隐函数及复合函数求导法则，推导出了系统庞加莱映射周期不动点的雅可比矩阵，根据雅可比矩阵的特征值分布情况，即可判断各不动点的自治振荡稳定性。
