Methods： Thirty-eight cases with cervical spondylosis causing vertebral artery insufficiency were treated by needling the cervical tendon for one-course treatment. After treatment, the vertebrobasilar blood flow was observed. Results： The vertebrobasilar blood flow of the patients was substantially improved. The total effective rate and marked effect rate were 100.0% and 68.4% respectively. Conclusion： Needling the cervical tendon can obtain an exact effect for cervical spondylosis causing vertebral artery insufficiency.展开更多

The OH emission spectra were investigated so as to know the naphthalene decomposing process. The by-products were analyzed and a decomposing theory in discharge was proposed. The results showed that higher voltage and relative humidity were effective on decomposition. The initial concentration affected the decomposing efficiency of naphthalene. When the initial naphthalene density was 17 mg/m3, the decomposition rate was found to be 70% under 14 kV. The main by-products were carbon dioxide and water. However, a small amount of carbonic oxide, 1,2-ethanediol and acetaldehyde were found due to the incomplete oxidization.展开更多
