@崔伟2152：unwilling to do什么意思 -
戚晴19287482830…… unwilling to do 不愿意做的 双语对照 例句: 1. One thing cook has been unwilling to do, however, is explain himself. 然而,库克一直不愿意亲自向公众解释. 2. If banks are unwilling to do this, central banks will have to replace them, as the federalreserve is now doing. 如果银行不愿意这样做,中央银行就得替它们这么做,就像美联储所做的那样
@崔伟2152：VB编程从键盘输入k,求1^2+2^2+3^2+…+k^2.求编程 -
戚晴19287482830…… k = val(inputbox(＂请输入k＂)) s = 0 for i = 1 to k s = s + i ^ 2 next msgbox ＂结果为＂ & s
@崔伟2152：已知单位负反馈系统的开环传递函数为G(s)=K(s+1)/s∧3+as∧2+2s+1,利用劳斯稳定求K和a? -
戚晴19287482830…… 令1+G(s)=0,得到特征方程D(s)=S(τS+1)(2S+1)+k(s+1)=2τS^3+(2+τ)s^2+(k+1)s+k. routh判据: s^3 2τ k+1 s^2 2+τ 1 s (2k+kτ+2)/(2+τ) s^0 k 要求第一列全部大于0,联立不等式解得:k>0,τ>-2or<-2-2/k
@崔伟2152：VB编程:输入正整数N,求最大的K,使得1*1+2*2+3*3+....+K*K<N成立 -
戚晴19287482830…… 算法如下,添加一个CommandButton测试: 注:因为K永远不可能大於N,所以就可以用For K = 1 To N作为循环条件... Private Sub Command1_Click() Dim N, K, Num N = InputBox(＂Please input a values of N:＂, ＂User Input＂) For K = 1 To N Num = Num + K * K If N - Num < 0 Then MsgBox ＂The max values of K is: ＂ & (K - 1) Exit Sub End If Next End Sub
