The problem of quadrature formula, normalization, symmetrization and peak spreading correction for experimental GPC chromatograms after partial smoothing or fittingacurve is discussed.
最后讨论了求积公式、归一化、对称化和GPC实验谱图的峰加宽改正问题。

Fittingacurve for an experimental energy spectrum of plasma particles with the least square method, a square error sum between the fitted curve and experimental spectrum data is usually minimized.
用最小二乘法拟合等离子体粒子能谱实验数据时，通常使拟合函数与实验能谱数据之间的误差平方和极小化。

On the basis of Chebyshev curvefitting method, a new method to design worn profile tread is proposed by this paper.
