According to the kernel estimating theory of nonlinear semiparametric models under the least - square principle , the structural formulae of the estimation of parametric and nonparametric components and the direct formulas of kernel estimation considering the second order items were given 摘要基于非線性半參數模型最小二乘核估計,給出了其參數分量和非參數分量估計的構造式,導出了參數分量和非參數分量顧及二次項直接解法的計算公式。

Element analysis apparatus and xps were taken to analyse the chemical components of the acquired products , the chemical elements of the systems were almost in according to which theoretical structural formula 利用元素分析儀和xps對合成產物的化學成分進行了分析,各體系的化學元素基本與理論化學式相符。
