Circumferential field intensity can be calculated by solving Laplace's equation in field domain or by finite-element method.

计算带偏心母线的圆环铁芯磁场的不对称分布有助于分析母线型和套管型电流互感器的误差特性，从而提出科学的计量方法。

According to the result, the confidence region of unknown parameters in single-index models is constructed. Finally, we consider the test of correlation and heterogeneity for hierarchical nonlinear mixed-effects models. According to Laplace approximation expansion of integrated log-quasilikelihood, a class of score test statistics is proposed. Under some very mild conditions, we prove the asymptotic distribution of the test statistics is a standard X~2-distribution. Through a Monte Carlo simulation study, the finite sample performance is examined.

最后，我们研究的第四个问题是分层非线性随机混合效应模型的相关性与异方差性检验问题，依据对数拟积分似然的Laplace近似展开提出了检验统计量，在一些正则条件下，得到了检验统计量的渐近分布是一个标准的χ~2-(来源：d7d7A65BC论文网www.abclunwen.com)分布，通过Monte Carlo模拟研究了其小样本的表现，实例验证了其实际应用。

The predicting results were compared with PLS, which shows that the latent root regression model can practically be used for the quantitative analysis of the biological samples with near-infrared spectra.

特征根回归法是对PCR建模方法改进的又一种化学计量学定量分析校正方法，该方法在对样品光谱提取主成份时考虑了待分析组分的作用，因此所建立的定量分析模型有好的分析效果。

A considerable amount of effort has been made into forcing lead dioxide to conform to exact stoichiometry.

相当多的努力一直被花费在强制性地把二氧化铅转变为化学计量意义上准确的Pb2O上。
