我們仔細研讀了由Z. Guo 、K. Nakanishi 和S. Wang 三位學者所寫的論文，其標題為“small energy scattering for the Klein-Gordon-Zakharov system with radial symmetry”，該論文探討了Klein-Gordon-Zakharov 方程的散射問題。作者將系統進行轉換和處理，接著給出球對稱版本的Strichartz 估計，最後使用估計證明了解的存在唯一性與漸近行為。而我們詳細的給出了在他們論文中所省略的細節和計算，並針對一些打字或論述的錯誤做了修正。

We study the paper “Small Energy Scattering with Radial Klein-Gordon-Zakharov System Symmetry(2012) ”, which was written by Zihua Guo, Kenji Nakanishi and Shuxia Wang. In that paper, they discuss the scattering problem of the Klein-Gordon-Zakharov system. First, they transform the system, then give the radial Strichartz estimate. Finally, they use the Strichartz estimate to prove the existence, uniqueness and asymptotic behavior of the solution. We give the detail of the calculation and proofs which are omitted in their papers and made some corrections for some typos.
