Methods: Sixty patients with CSA were randomly allocated into an observation group or a control group, with 30 cases in each group. The observation group was treated with warm needling moxibustion plus Kai Qing Long Suo tuina therapy, while the control group was treated with warm needling moxibustion alone. Warm needling moxibustion was conducted once every other day and tuina was con ducted once a day, 7-day treatme nts for one course. The clin ical efficacy and vertebral artery blood flow was observed after one course of treatment. Results: After treatment, the total effective rate was 93.3% in the observation group versus 80.0% in the control group, and there was a significant differenee between the two groups (P<0.05). After treatment, the systolic blood flow velocity of vertebral artery increased in both groups, with statistical significanee compared with that before treatment (both P<0.05), and the blood flow velocity in the observation group was faster than that in the control group, with statistical significanee between the two groups (P<0.05). Conclusion: Both warm needling moxibustion plus Kai Qing Long Suo tuina therapy and warm needling moxibustion alone are both effective for CSA, can improve the systolic blood flow velocity of vertebral artery. The curative effect of warm needling moxibusiton plus Kai Qing Long Suo tuina therapy is better than that of warm needling moxibustion alone.展开更多
UN燃料具有铀密度高、熔点高、热导率高、热膨胀系数低、辐照稳定性好等优点，是未来空间核电源、核火箭、快堆和ADS的重要候选燃料。本文采用金属铀粉与氮气在300～400℃直接发生化合反应，制得单相U2 N3粉末。粒度为38.3μm的 U2 N3...UN燃料具有铀密度高、熔点高、热导率高、热膨胀系数低、辐照稳定性好等优点，是未来空间核电源、核火箭、快堆和ADS的重要候选燃料。本文采用金属铀粉与氮气在300～400℃直接发生化合反应，制得单相U2 N3粉末。粒度为38.3μm的 U2 N3粉末在1600℃真空热压烧结，制得相对密度为93.5％、存在少量金属铀相的U N陶瓷；而18.1μm的U2 N3粉末在1550℃真空热压烧结，制得相对密度为96.1％、不残留金属铀相的 U N陶瓷，U与N的总质量分数为99.57％，每个金属杂质含量均低于50μg/g ，氧含量为1048μg/g ，碳含量为502μg/g。U2 N3在1027℃以上将会完全分解成UN ，UN在1627℃以上也会发生分解。展开更多
