Results For single treatment groups,serum drug concentration of chlorpromazine and clozapine were related to age of patients (P＜0 05),concentration of clozapine was related to dosage (P=0 01).For combination group,concentration of chlorpromazine was related to dosage (P＜0 01),also related to scores of PANSS and general psychopathological symptoms (P=0 01),concentration of clozapine was related to scores of PANSS,negative and general psychopathological symptoms (P＜0 05).Multiple linear regression analysis showed that forms and methods of treatment affected concentration of chlorpromazine,age of patients and methods of treatment affected concentration of clozapine.

结果 单用氯丙嗪和采用氯氮平组的血药浓度均与年龄相关（P＜0 05），氯氮平血药浓度与剂量线性正相关（P=0 01）；在双氯组中的氯丙嗪血药浓度与剂量线性正相关（P＜0 01），与PANSS总分及一般精神病理分相关（P=0 01），而氯氮平血药浓度与PANSS总分、阴性量表分及一般精神病理分明显相关（P＜0 05）；多元回归分析显示，治疗形式和治疗方法影响氯丙嗪血药浓度，年龄和治疗方法影响氯氮平血药浓度。

Multivariate logistic regression analysis was used to correlate the tumor response to Tmax,Tmin, Tav, T90, T50, T10,%T, and the cumulative minutes when the temperature reached 42.5℃ in the tumor center (Cum min Tcenter＞42.5℃).

最终进行肿瘤反应与肿瘤内最高温度，最低温度，平均温度， T90， T50，T10，%T以及肿瘤中央区测温点温度大于42℃， 42.5℃的持续时间（Cum min Tcenter＞42℃， 42.5℃等热参数的多元回归分析。

Methods the family environment scale manual and conners child behavioral scale were used to investigate both behavioral problems and family environment in 100 children aged from 3 to 12 years (including 50 children with asthma and 50 healthy children). the results were analyzed using multiple regression analysis.

方法采用家庭环境量表中文版和conners儿童行为问卷分别对哮喘儿童50名、正常儿童50名(3～12岁)行为问题及家庭环境进行调查，并对调查结果进行多元回归分析。

Based on literature review of customer service, this paper explore the relationship between various third-party influential service factors and logistics cost management performance of consigners by using multivariable regression analysis, We propose that the value-added service content and greater contribution of service level have positive effect on consigners' cost management performance, and these results has valuable instruction to third-party logistics on how to provide customer service effectively as well as effectiveness.

本文在对以往物流客户服务管理进行理论回顾和归纳的基础上，针对中国企业的背景，利用多元回归分析探索了各种第三方物流服务影响因子对委托客户企业供应链物流成本管理绩效的影响，提出物流服务内容上的增值程度和物流服务水准上的贡献程度对于委托客户企业实现良好的供应链物流成本具有较高的影响，从而揭示了当今中国第三方物流如何从效率和效能两个方面入手提供良好的客户物流服务。
