摘　　要：介绍用渐近法计算楔形直杆纵振与扭振的自主频率，给出一级近似下的频率计算公式。该法计算简单，结果接近于其它方法。This aticle presents the application of asymptotic method to calculation of the natural frequency as wedge-shape straight bar vibrates longitudinally and torsionally. The first-order approximate formulae are given which are easy to use. The calculation results are close to that of the Bessel function method.
