A complete quartic polynomial consists of 15 terms . 一个完整四次的多项式由15项组成。
Moreover equations of degree higher than quartic often arise in equilibrium calculations . 况且,在平衡计算中常常发生比四次方程还高的高次方程。

Quartic convolution interpolation and its application in digital maps 四次卷积插值及其在数字地图中的应用
The result shows that the quartic phase coupling component and quadratic - to - cubic phase coupling one are only extracted using the fifth order cumulants of complex signals 研究表明:复数信号的五阶累积量是提取四次相位耦合分量、二三对相位耦合分量的必要工具。
