The decay rate of the corresponding strong solution at infinity is also given for some kinds of initial data with exponential decay.
若其初值以指数方式衰退，且空间可微，则此强解在之后的时间内也将以指数方式衰退。
In the case of nonuniform decay in the energy space, we derive explicit polynomial decay estimates valid for regular initial data.
在能量空间中，当梁的能量非一致衰减时，由初始条件得到了梁的能量多项式衰减估计。
The coefficient of s then immediately indicates the speed of decay, and it takes 4T seconds for the transient to decay to 1.8% of its initial value.
的系数立即给出了衰减的速度。而且，当时间为4T时，瞬态解衰减至初始值的1.8%。
This paper discusses initial boundary value problem (1) - (3). Under somewhat more general condition, the uniform boundness of the solutions is demonstrated and the decay estimate is obtained.
