【摘要】 把含有小参数的二阶线性齐次方程转化为含有大参数的二阶线性齐次方程，然后求出含有大参数二阶线性齐次方程的渐近解，利用此渐近解即可求出楔形杆件结构的纵振自主频率反弹性失稳时的临界荷载。更多还原

【Abstract】 An asymptotic solution for second order linear homogeneous equations with big parameter is given by conversion of second order linear homogeneous equations with small parameter into these with big parameter The frequency and critical load of free longitudinal vibration of structures with tapered members are derivated by using the asymptotic solution when they are under a condition of elastic instability.更多还原
