In the"willow leaf"TEM horn, the characteristic impedance varies from 50Ω to the 377Ω free space impedance, thus its metal plates have shapes similar to willow leaf. The constant impedance TEM horn consists of two tri-angular metal plates, with it's characteristic impedance at arbitrary cross-section being a constant.

The lesion, the changes of activity of cholinesterase and acid phosphatase of motor neurons in lateral nucleus of spinal cord anterior horn, the function of axoplasm transportation and nerve conduction, the regeneration of axons and myelin sheath, and the recovery of sciatic nerve function were examined at 7, 14, 30 and 90 days intervals after operation, using Nissl and enzyme histochemistry staining, electrophysiological technique, hydrogen-peroxide oxidoreductase retrograde trace method, axon image analysis, and measurement of sciatic function index. The spinal cord anterior horn of injury side was compared to the correspondence region of spinal cord.

Based on the above theories, some vibration characteristics of longitudinal acoustic horns are analyzed with finite element analysis software ANSYS. Some factors influence to large end amplitude distribution is studied such as big end diameter, length of horn, and diameter ratio of big end to small one. In addition, we carry on analysis and research to resonance frequency of large cross-section acoustic horn, amplitude magnification factor, wave node position of horn, transverse vibration situation and so on, and some related change rules are obtained.
