Study limitations include some unblinded assessments, lack of relevant and valid measures of social cognition among stable outpatients at the start of the study, problems with using neuropsychological tests as longitudinal outcome measures, possible practice effects, and lack of generalizability to all patients with schizophrenia.

该项试验限制包括某些非双盲性评估、缺乏在试验初对於稳定病患确切且确效的社会认知评估方法、使用神经精神测试作为纵向结果评估方法所产生的问题、以及可能的实务上的影响、与缺乏对所有精神分裂症病患的一般化。

Currently, the anti-influenza antibody is measured by the hemagglutinin- inhibition test. Although it is simple, but the result is easily influenced by the quality and species source of the red blood cells used. Antibody titer determined by HI test cannot reflect the protection titer either.

血球凝集抑制试验(hemagglutinin- inhibition test，HI test)是一至今仍普遍使用来测定抗流行性感冒病毒抗体的方法，此方法虽然快速、简便，但测定结果容易因为红血球的品质及来源而受影响，且血球凝集抑制试验所测定出的抗体效价亦不能反应真正的保护能力。

A finite element analysis on the new method is presented in this paper. Based on the finite element analysis, tension tests of 18 steel bars in different diameters and holes are carried out. The results of tests, which are according with that of finite element analysis, validate the new method to determine real stresses of steel bars by drilling/enlarging small holes. Furthermore, some suggestions in using of the new method are given.

本文针对该新方法进行了有限元分析，并在此基础上进行了18种不同钢筋直径和不同孔径的带孔短钢筋拉伸试验，试验结果与相应有限元计算结果一致，验证了钻／扩孔确定钢筋实际应力的新方法，并提出了若干工程适用建议。
