Prick-bloodletting combined with cupping on the back for 52 cases of acne

Objective To introduce the experience of professor YIN Ke-jing in selecting reaction points on taiyang meridian on the back for acne. Methods Positive reaction points on taiyang meridian of the medial border of scapulae on the both sides of the back were selected for prick-bloodletting combined with cupping, and the treatment was conducted once every three days,3 treatments as one course of treatment and 2–3 courses of treatment were needed. Results After treatment for two courses of treatment, the total effective rate of the 52 patients was 96.2%. Conclusion The application of the theory of corresponding meridian of meridians and collaterals in treatment of acne made the treatment simple and convenient; with less acupoints selected, rapid effect and definite clinical efficacy, this method is worthy of being generalized.

热效率测量结果的不确定度分析——基于中餐燃气炒菜灶能效等级检验标准

在实验室条件下对中餐燃气炒菜灶热效率测量结果的不确定度进行分析,以期提高中餐燃气炒菜灶能效等级检验的准确性和可靠性。通过建立试验环境,阐述试验方法,分析不确定度来源,建立了不确定度分析模型,从而对其进行A类和B类评定,并得到其合成不确定度。当包含因子k=2时,热效率测量结果的扩展不确定度为1.0%,热效率测量不确定度结果的报告为η=(31.8±1.0)%,满足实验室不确定度评定要求。
