为了满足耐海水腐蚀、高导热率和承压能力要求,冷却器盖均采用硅黄铜制造。某厂在冷却器盖的生产过程中,铸件废品率高达60%,主要问题是铸件在水压测试中出现渗漏。分析了冷却器盖铸件的渗漏缺陷。结果表明:硅的加入量和浇注温度偏高,硅熔化不完全是导致此类铸件产生渗漏的主要原因。针对性地采取措施后,冷却器盖铸件的成品率大幅提高,达到了90%以上。

养精种玉汤临床多用于治疗各种不孕症、多囊卵巢综合征、月经过少、闭经溢乳综合征、体外受精-胚胎移植等疾病,疗效确切。但是记载养精种玉汤的古代文献资料较少,现代研究大部分是临床试验和基础实验研究,且存在一些不足:①有些临床试验缺乏中医辨证,治疗疾病未辨证而直接辨病论治;②缺少治疗后随访及远期疗效评价,对妊娠结局的随访亦未予以特定的描述,不便于对研究结果做进一步分析;③相关研究中应完善血清激素水平指标的监测,以增加研究结果的说服力;④大部分研究样本量偏少,影响统计学结果,降低了结果的可靠性;⑤该方的安全性研究仅仅停留在动物实验阶段。因此,今后的研究应以辨证论治为基础,增加样本量,完善相关激素水平的检测,关注随访结果,为临床用药安全性提供更可靠的依据。

Journal of Zhejiang University-Science A(Applied Physics & Engineering) 2008年第8期9卷 1061-1069页

作者： zhi-qiang GE zhi-huan SONG State Key Lab of Industrial Control Technology Institute of Industrial Process Control Zhejiang University Hangzhou 310027 China

In this paper, we describe a new batch process monitoring method based on multilevel independent component analysis and principal component analysis (MLICA-PCA). Unlike the conventional multi-way principal component analysis (MPCA) method, MLICA-PCA provides a separated interpretation for multilevel batch process data. Batch process data are partitioned into two levels: the within-batch level and the between-batch level. In each level, the Gaussian and non-Gaussian components of process information can be separately extracted. I2, T2 and SPE statistics are individually built and monitored. The new method facilitates fault diagnosis. Since the two variation levels are decomposed, the variables responsible for faults in each level can be identified and interpreted more easily. A case study of the Dupont benchmark process showed that the proposed method was more efficient and interpretable in fault detection and diagnosis, compared to the alternative batch process monitoring method.
