 Recently, Tzeng and Yu showed if a = l the Goppa codes with L=GF (qm) can be extended to cyclic codes, then g(z) is quadratic. 最近Tzeng和Yu又指出,当a=1时,L=GF(q~m)的Goppa码可扩展成循环码,其必要条件是g(z)为二次的。 短句来源 Because all elements of the multiplicative group F~*_p are square ,Gauss by that has proved the quadratic reciprocity law(l/p)=(p/l)(-1)~ε(l)ε(p) of Legendre's symbol in the finite field. 高斯利用有限体中的元都是二次的这一性质,推证了Legendre符号的二次反比定律(l/p)=(p/l)(-1)ε(l)ε(p). 短句来源 Piecewise quadratic trial functions and piecewise constant test functions are used to finally obtain the error estimates in L~2 norms and H~1 norms of the numerical schemes. 文中选取分片二次的试探函数空间和分片常数的检验空间，最终得到数值格式的L~2模和H~1模估计。 短句来源 On this basis, the quadratic and the linear cases of state inequality constraints are studied and the results in practical sense are obtained. 在这个基础上,对二次的和线性的状态不等式约束情形进行研究,得到较为实用的结果。 短句来源 The traditional Hopfield neural network plays an important role in association memoryed, computation optimization and so on. However, there exists a problem in this network, that is to say, it can only solve linear or quadratic optimal problems. 传统的Hopfield网络在联想记忆、优化计算方面发挥了重要作用,但该网络存在一个弊端,即它只能处理线性或二次的最优化问题。 短句来源 更多

 There are two features used in first method: area distribution of 3D model surface and latitude orientation average radius distribution. Quadratic form distance function has been applied to calculate the similarity of two feature vectors and two passes are needed to search database in first method. 第一种检索技术使用了两个特征：面积分布和纬度方向平均半径分布，在相似度计算使用了二次方程式距离计算公式，数据库检索采用了分步检索方法。 短句来源 The ZIP load model is introduced and the equivalent line current is divided into real and imaginary parts based on Thevenin equivalent circuit. After eliminating the active power and substituting the reactive power of ZIP load for the imaginary part,a quadratic is obtained,which is processed by the root discriminant to deduce a voltage stability index VSIQ. 首先介绍了ZIP负荷模型,然后用戴维南等值电路简化系统,将线路电流表达式整理成实部和虚部,消去负荷有功后代入ZIP负荷模型中的无功表达式得二次方程式,用根判别式得到以无功表示的电压稳定指标VSIQ; 短句来源 The respiration rate of pea was measured by the close system method and the permeable system method. The parameters of the respiration model were determined by applying the Michaelis-Menten equation and the quadratic equation. 采用封闭系统、渗透系统法测算青豌豆呼吸速率,应用Michaelis-Menten式方程、二次方程式进行呼吸速率模型参数表征。 短句来源
