All cases were HIV carriers. The 6 point behavioral rating scale (BRS 6) was used to observe the effect before and after treatment. The results indicate arranged electro acupuncture can cure or reduce the severe pain of postherpetic neuralgia of HIV carriers and the effect was better than medicine.展开更多

This paper focuses on a power quality improvement project to solve these problems. A hybrid compensating scheme, including an active compensator and a passive compensator, is carried out. Because of the specificity of oilfield drilling electrical system, compensators are redesigned against features of this application background. And then the current detection point arrangement of this hybrid system is also taken into consideration to build the whole system much more effective and reliable. Now the improvement project is already implemented in application field, and the power quality of the system is greatly improved.展开更多
