    Assume $t1=0x12345678,$t0=87654321, after executing instruction "add $t2, $t1, $t0" and "addu $t3,$t1,$t0",the values of $t2 and $t3 are same.

      设f(1)=0,t<3,试确定信号f(1-1)+f(2-t)为0的t值 A: t>-2或t>-1 B: t=1或t=2 C: t>-1 D: t>-2

      已知T(1)=9,T(2)=8,T(0)=5,Total=T(1)+T(2)+T(0),则Total=()。

      设α1=(1,4,3,-1)T,α2=(2,t,-1,-1)T,α3=(-2,3,1,t+1)T,则 A: 对任意的t,α1,α2,α3必线性无关. B: 仅当t=-3时,α1,α2,α3线性无关. C: 若t=0,则α1,α2,α3线性相关. D: 仅t≠0且t≠-3,α1,α2,α3线性无关.

      已知“syms x y a t r; x=r*cos(t); y=r*sin(t); f=sqrt(a^2-x^2-y^2); r1=0; r2=a; t1=0; t2=2*pi; f1=int(f*r,r,r1,r2); I=int(f1,t,t1,t2)”,则下列说法正确的是【】

      假设有模板定义如下:template T Min(T m1, T m2 ){return (m1 A: template float Min(T m1, T m2 ){return (m1 B: template T1 Min(T1 a[ ], T2 n ){T1 minnum=a[0] ;for (int i=0 ;ia[i]) minnum=a[i];return minnum;} C: template T1 Min(T1 m1, T2 m2 ){return (m1 D: template T Min(T m1, T m2, T m3 ){T temp=Min(m1,m2) ;return Min(temp , m3) ;}
