Considering Cauchy problem of 1-D compressible fluide with adiabatic exponent 1,under some reasonable assumptions,a sufficient and necessary term is obtained for guaranteeing the global existence of classical solutions,this result is a supplement and a perfecting for the existed related documents.
考虑具绝热指数1的一维非等熵可压流体力学方程组的Cauchy问题,在一些合理假设下,得到了其整体经典解存在的一个充分必要条件,这一结果是对已有相关文献的补充和完善。
