Emulation research and simple analysis are taken in this method, and through comparing whit non linear interpolation algorithm ( 3 order polynomial interpolation ), some mechanisms when implementing neural network in data fusion are pointed out. 对所提方法进行了仿真研究和简单分析,并与非线性插值(三次多项式插值)作了比较,粗浅地指出:神经网络在数据融合过程中的实现机理。

By means of the parametric variational method, the differential equations of amplitude and phase of a two order non linear vibration system are established. The equations are then expanded with a special sphere polynomial as to obtain the approximate solutions, which are compared with others. 应用参数变分法建立了二阶非线性振动系统的振幅、相位的微分方程,然后利用特种球多项式将其展开,求得近似解,并与其它方法进行了比较。
From these properties, these four non - linear prob-lems could be transformed into combinatorial problems and could be solved by algorithms with polynomial - time iterations. 基于这种性质,这四个非线性优化问题便转化为组合问题,从而得到迭代次数为多项式的算法。
