It is proved that under the condition that normalized coordinates exist the system must be weakly linearly degenerate if the Cauchy problem for general quasilinear hyperbolic systems with characteristics with constant multiplicity with arbitrary small C 1 initial data always admits a unique global C 1 solution u=u(t,x) on t≥0.

Under the assumption of non-weak linear degeneracy, we obtain the relations between the life-span of classical solution to quasilinear strictly and non-strictly hyperbolic system and the index α of non-weak linear degeneracy under weaker decaying rates of the initial data.
本论文系统地论述了具有小而衰减初值的拟线性双曲组经典解的奇性形成，分别得到了严格双曲组与非严格双曲组在非弱线性退化假设下经典解的生命跨度与非弱线性退化的指标α和初值的衰减程度的关系。
