摘　　要：介绍了气动BGK格式的最新发展 ,在此基础上对原格式进行了适当简化 .数值验证表明简化后的格式不但保留了原格式的强健性和自动满足熵条件等优点 ,而且算法更加简明 ,计算量更小 .A newly developed gas kinetic BGK scheme is further simplified. Numerical tests show that the new simplification not only keeps the advantages of the old scheme, such as its robustness and automatic satisfaction of the entropy condition but also makes the scheme simpler and more efficient.
