现代金属加工酸洗环节基本采用工业盐酸生产,但酸洗后基板表面通常存在酸斑、局部过蚀等轻微缺陷。由于金莱冷轧带钢有限公司在产品特点上对表面质量有严格的要求,所以至今酸洗工序仍采用医药盐酸进行高成本生产。研究证明,向工业盐酸... 现代金属加工酸洗环节基本采用工业盐酸生产,但酸洗后基板表面通常存在酸斑、局部过蚀等轻微缺陷。由于金莱冷轧带钢有限公司在产品特点上对表面质量有严格的要求,所以至今酸洗工序仍采用医药盐酸进行高成本生产。研究证明,向工业盐酸中添加合适的金属表面处理剂(又称缓蚀剂)可以防止酸洗后基板表面出现酸斑和局部过蚀,改善表面质量,替代医药盐酸生产。 展开更多

OBJECTIVE: To compare the efficacy of an acu- puncture regimen for persistent allergic rhinitis (PER), aimed at improving a patient's mind or Shen in Traditional Chinese Medicine, to that of a sec- ond-generation H-receptor antagonist, cetirizine hydrochloride. METHODS: This multicenter, randomized, con- trolled clinical trial on PER will be conducted at three institutions in China. The total study period will be 9 weeks. After a 1-week preparatory screen- ing period, 240 eligible participants with PER willbe randomized to receive acupuncture or pharma- cotherapy (1: 1) for 4 weeks with a 4-week fol- low-up. The primary outcome will be changes in 7-day average total nasal symptom score. Second- ary outcome measures include rhinoconjunctivitis quality of life questionnaire score and total non-na- sal symptom score. RESULTS: The presence and seriousness of psycho- logical and emotional impairments should be con- sidered in therapeutic programs for allergic rhinitis. No clinical trial for treating allergic rhinitis via acu- puncture regulation of psychological and emotion- al activities has been reported. CONCLUSION: The findings of the trial will allow us to determine the effects of the mind (Shen)-regula- tion treatment approach. We will also be able to confirm if the effects of acupuncture are equivalent to those of the conventional drug cetirizine hydro- chloride. 展开更多
