The iris radius of 60 (93 eye) patients with early pupillary block primary angle closure glaucoma was measured with this method, it showed:(1) there was a statistically significant difference in iris radius between the patients with early stage primary pupillary block angle closure glaucoma and the normal subjucts (53 cases 106 eye) with the age matched group (P.01),(2) it is proved with the stepwise discriminatory analysis that the iris radius-the most significant bio-anatomic parameter of the anterior segment is usefull to diagnose early primary pupillary block angle closure glaucoma by stepwise discriminatory analysis.

本研究用此测量法测量了60例93只眼早期原发性瞳孔阻滞性闭角型青光眼的虹膜曲率半径，发现：（1）早期原发性瞳孔阻滞性闭角型青光眼患者的虹膜曲率半径小于同年龄正常人（53例106眼）的虹膜曲率半径，其差异具有显著性统计学意义（P.01）；（2）经多因素逐步判别分析证明本研究所提出的活体眼前节解剖学测量参数——虹膜曲率半径有助于原发性瞳孔阻滞性闭角型青光眼早期诊断。

Results of stepwise discriminant analysis indicated that at Datang the key factors affecting habitat use by hoolock gibbons in spring were two factors, and that there were three factors (distance to open field, average height of bamboo and liane density) impacting habitat use by hoolock gibbons between Nankang and Datang in spring.

判别分析结果显示，在大塘影响白眉长臂猿春季生境利用的关键因子是藤本密度和坡度2个因子；影响赧亢与大塘白眉长臂猿的则是距空旷地距离、竹子平均高度和藤本密度等3个因子。

Base vectors are selected for formulating the nonlinear mapping. An approximate explicit expression is formed by using the Nystrm method for nonlinear mapping which is not available originally. The data in the nonlinear input space is mapped into some linear feature subspace and fisher linear discriminant analysis is computed for the mapped data.

首先提取基向量；然后采用Nystrm方法，以基向量为训练样本，将形式未知的非线性映射近似表达为已知形式的非线性映射，这种近似的非线性映射将变量由非线性的输入空间转换到线性的特征子空间；最后对映射数据进行线性Fisher判别分析。

A DPLS discriminant analysis model was developed based on spectra region from 400 nm to 2 498 nm with mathematic pretreatment 2-8-6-1 and scatter correction treatment the standard normal variate. The accurate discriminant rate of calibration and external validation was 95.7% and 95.6% respectively. For the adulterated samples (MBM mass percentage≥5%), the accurate discriminant rate was 100%.

建立的判别分析模型：数学预处理方法为2-8-6-1，散射校正方法为变量标准化处理，光谱范围为全谱（408～ 2 492 nm），定标模型的正确判断率为95.7%，外部验证正确判断率为95.6%，对于掺入量≥5%MBM时，正确判断率为100%。

ICA, because its components are independent and it use high order statistic information, has much superior in making discrimination analysis.

利用独立分量作为特征进行判别分析，不仅是特征之间相互独立，而且还能充分利用变量的高阶统计量信息，具有很强的优势。
