Results Singlefactor logistic regression analyses showed that there were very significant differences in 11 factors between the 2 groups（all P＜0.01）;multiplefactor conditional logistic regression analyses in the 11 factors showed that the main risk factors of psychoactive drug abuse in middle school students were parents' drug abuse,poor performance record,absent from class,violence,selfconscious loneliness and unharmony family relation,the main protective factor was more exchanges between parents and children.

结果 两组自拟问卷单因素Logistic回归分析发现，11个因素有极显著性差异（P均＜0.01）；将11个有显著意义的因素进行多因素条件Logistic回归分析，结果发现影响中学生精神活性药物滥用行为的主要危险因素为父母有药物滥用、学习成绩差、缺课、暴力行为、自觉孤独、家庭关系不和睦，而多与父母交流则为主要保护因素。

Smoothing functions can transform the unsmooth support vector regression into smooth ones,and thus better regression results are generated.

By using the quadratic regression orthogonal experimental method with three factors and five levels, the relationships between the microwave power applied, the sample thickness, the pressure in drying chamber and the rehydration ratios, chlorophyll and vitamin C retention ratios of dried Chinese gooseberry slices, as well as the energy consumption of drying process, were analyzed, and the regression mathematical models for experimental indices and factors were established. At last, the optimal combination of the parameters for the microwave-vacuum drying technology of Chinese gooseberry slices was obtained through nonlinear optimization method with many targets.

通过3因素5水平的二次回归正交试验，分析了微波功率、物料厚度、干燥室压力与猕猴桃切片干制品复水率、叶绿素含量、维生素C含量及单位耗电量的关系，建立了各指标与试验因素间的回归数学模型，并利用多目标非线性优化方法，确定了猕猴桃切片微波真空干燥最优工艺参数。

The patient's rating was then dichotomized and fitted in a multiple logistic regression. After controlling for the hospital accreditation levels, patient's diagnosis, and patient's education level in the regression model, we found that the percentage of nurses with bachelor degree, years of clinical experience, and total nursing hours were significantly and positively associated with patient's ratings.

在双变项分析中，护理师比例与大学学历以上比例具高度相关，为了避免「共线性」的问题，最后选择大学学历以上比例纳入多变项分析；最后以病人评分高低为依变项进行逻辑斯回归，在控制医院评鉴等级、病人疾病诊断别、以及病人教育程度后，结果显示护理人员大学学历以上比例、平均临床工作年资及急性病房护理时数，对病人观点照护品质评分均呈现显著正向影响。
