摘要
We study upper and lower bounds for the pull-in voltage and the pull-in distance for the one-dimensional prescribed mean curvature problem arising in MEMS - u √ (x) 1+(u(x))2 ! = λ (1-u)p , u < 1, - L < x < L, u(-L) = u(L) = 0, where λ > 0 is a bifurcation parameter, and p, L > 0 are two evolution parameters. We further study monotonicity properties and asymptotic behaviors for the pull-in voltage and pull-in distance with respect to positive parameters p and L.
