A 2D harmonic model based on the quaternion was constructed, and a special four-order cumulant was defined.The 2D cubic nonlinear phase coupling of additive color Gaussian noises was analyzed. 构造了合适的基于四元数的二维谐波模型，根据此模型定义了特殊的四阶累积量切片，分析了加性高斯在有色噪声中的二维三次非线性相位耦合。
It is shown that the U centers are formed along with the F centersin the crystals of KCl:Li containing OH-ions during additive coloration. 指出含 OH~-的 KCl:Li 晶体在附加着色的过程中,U 心和 F 心一起形成。
Paprika Oleoresin is a kind of dark red oily liquid pigment extracted from dried red chili, and belongs to natural food additive colorant. 辣椒红色素是从红辣椒干中提取精制而得的一种深红色油状液体色素，属天然食品添加剂中的着色剂。
This paper proposes an adaptive identification algorithm for nonminimum phase ARMA models in additive colored Gaussian noise. 本文提出了一种加性有色高斯噪声中因果非最小相位ARMA模型的自适应辨识算法。
