1. Page 1442, the first formula in (73) should read as follows:

$$\begin{gathered} {{{\mathbf{\lambda }}}_{{20}}} = [({\mathbf{I}} + {\mathbf{L}}_{0}^{{'(1)}}({{{\mathbf{\varepsilon }}}_{1}}{\mathbf{I}} - {{{\mathbf{\varepsilon }}}_{m}}))({\mathbf{I}} + {{3}^{{ - 1}}}\varepsilon _{1}^{{ - 1}}(1 - {v}{\text{'}}) \\ \, \times ({{{\mathbf{\varepsilon }}}_{2}} - {{{\mathbf{\varepsilon }}}_{1}}{\mathbf{I}})) + {v}{\text{'}}{\mathbf{L}}_{0}^{{'(1)}}({{{\mathbf{\varepsilon }}}_{2}} - {{{\mathbf{\varepsilon }}}_{1}}{\mathbf{I}}){{]}^{{ - 1}}}, \\ \end{gathered} $$

2. Page 1442, the formula (75) should read as follows:

$$\begin{gathered} {{{\mathbf{E}}}_{1}} = ( - {{{\mathbf{\beta }}}^{{(1)}}} + \varepsilon _{1}^{{ - 1}}[ - {{3}^{{ - 1}}}{{({{a}^{{(2)}}}{\text{/}}r)}^{3}}{\mathbf{I}} + {{({{a}^{{(2)}}})}^{3}} \\ \, \times {{r}^{{ - 5}}}({\mathbf{r}} \otimes {\mathbf{r}})]{{{\mathbf{\alpha }}}^{{(1)}}}){{{\mathbf{E}}}_{0}}, \\ \end{gathered} $$
