中文摘要：
研究了一类具耗散项波动方程的初边值问题.借助偏微分方程的一些标准技巧对非线性项进行估计,利用嵌入定理和算子半群的方法证明了在相对较弱的条件下上述问题整体解的存在唯一性.
英文摘要：
The initial boundary value problem for a class of wave equations with a dissipative term was studied. By some standard techniques of partial differential equation, the non-linear term was estimated. Adopting embedding theorem and the method of semigroup, the existence and uniqueness of the global solutions for the abovementioned problem were obtained under rather mild conditions.
