对三维空间中的射影变换加以分析，说明其行、相关系数的几何意义及将三维非满秩射影变换改为二维满秩射影变换的处理方法进行探索，这对计算机辅助设计中的图形处理和建立图形数据库是有利的。

This algorithm is applied in a typical sun-synchronous satellite, by using Spearman rank order correlation coefficient to compare the result with state-of-theart researches.

通过一颗典型的太阳同步轨道卫星为例，引入Spearman等级相关系数与最新研究成果相比较的方法，验证了该方法的合理性和正确性。

Spearman rank correlation coefficient was employed to assess the relationship between serum CXCL16 level and Gensini score. Results In patients with ACS the level of serum CXCL16 was significantly increased compared with control and SAP patients. The serum CXCL16 concentration was positively associated with ACS.

结果 血清CXC趋化因子配体16水平在急性冠状动脉综合征组显著增高，其与急性冠状动脉综合征呈正相关，而与用药情况、血脂及C反应蛋白水平无相关。

Methods Sera derived from 226 SLE cases and 183 healthy controls were tested for ANA and all parameters were compared such as sensi- tivity,specificity,accuracy,positive predictive value,negative predictive value,positive likelihood ratio,nega- tive likelihood ratio,result consistency,rank correlation coefficient and kappa of ANA detected by IFA...

方法同时采用IFA法和ELISA法检测血清ANA共409例，其中SLE 226例和健康对照183名，将两种方法检测结果的敏感度、特异度、准确度、阳性预测值、阴性预测值、阳性似然比、阴性似然比、结果符合率、判断一致性κ值及秩相关系数进行比较分析；通过ROC曲线比较两种方法的准确度；结果不一致标本进行可提取性核抗原抗体谱检测分析；同时将IFA法检测不同荧光模型样本分别与ELISA结果进行相关分析。
