It studies the effect of physical disturbance on the structure of needle coke. The structure of needle coke is characterized by scanning electron microscope and x-ray diffractometer, and the influence mechanism is analysed. Results showed that the structure and property of needle coke could be effectively improved by magnetic field and ultrasonic cavitations, such as degree of order, degree of graphitization and crystallization. Comparatively speaking, the effect of magnetic field was greater. The graphitization degree of needle coke prepared under the effect of magnetic field is up to 45.35%.展开更多

Methods Twenty patients with spasmodic torticollis were treated by acupoint magnetic therapy at Fengchi （风池 GB 20）, Dazhui （大椎 GV 24） and Shenzhu （身柱 GV 12）. Once a day, ten days as a course of treatment, 24 treatments were given. Results Six cases were cured and 9 cases were markedly effective, 3 cases were effective and 2 cases were ineffective with the cured rate of 30% and the effective rate of 90%. Conclusion Acupoint magnetic therapy has sound effect in the treatment of spasmodic torticollis.展开更多
