摘要
This paper studies the life span of classical solutions to where a is a positive real number, f∈C<sub>0</sub><sup>2</sup>（R）, g∈C<sub>0</sub><sup>1</sup>（R）, 8 is a small parameter. The upper and lower bounds of the same order of magnitude for the life span are obtained respectively.
This paper studies the life span of classical solutions to where a is a positive real number, f∈C_0~2(R), g∈C_0~1(R), 8 is a small parameter. The upper and lower bounds of the same order of magnitude for the life span are obtained respectively.
