After John wrote the abstract "结合数值模拟和理论分析,研究凝聚介质中斜激波反射.采用龙格-库塔控制体积间断有限元方法,数值求解“刚性气体”状态方程形式下的欧拉方程组；理论分析凝聚介质中斜激波反射模式；运用激波极曲线理论,给出典型激波强度下正规反射向非正规反射过渡的临界角及波后状态.比较数值模拟结果和激波极曲线理论分析结果,得到典型弱、强斜激波的反射图像.", he wrote these keywords "反射, 典型, 曲线". Do you think his choice of keywords was correct? Answer yes or no.
