We discuss the existence results of the parabolic evolution equation d(x(t)+g(t,x(t)))/dt+A(t)x(t)=f(t,x(t)) in Banach spaces, where A(t) generates an evolution system and functions f,g are continuous.
讨论了Banach空间中抛物发展方程d(x(t) +g(t,(x) ) ) /dt +A(t)x(t) =f(t ,x(t) )的存在结果 ,这里A(t)生成一个发展系统 ,函数f,g是连续的 。
We prove that the system generate an evolution system when η(t) is a continuous function and η(t)∈∨, 0<η_0η(t)M.
讨论变系数Euler-Bernoulli梁振动系统utt(x,t)+η(t)uxxxx(x,t)=0, 0
A vibrating system consisting of a flexible beam controlled by a variabling velocity feedback force was studied,and the existence of evolution system for the vibrating system was proved.
文章主要讨论了一端固定另一端自由的柔性臂振动系统的端点变速度反馈控制问题,证明了变速度反馈梁振动系统生成一个发展系统。
