  • 第7题:

    设a,b,c均为向量,下列等式正确的是:
    (A) (a + b)(a-b) = a 2 - b 2 (B) a.(a.b) = a 2 b
    (C) (a.b)2 = a 2 b 2 (D) (a + b) × (a - b) = a × a - b × b


    答案:A
    解析:
    (a + b)(a -b) = a.a -a.b + b.a -b.b = a 2 - b 2,选项(A)正确; a.b = a b cosθ, (a.b)2 = a 2 b 2 cos2 θ,选项(C)错误;(a + b) x (a - b) = a x a - a x b + b x a - b x b = a x a - 2a x b - b x b,选项(D)错误。 点评:a.b = b.a a x b = -b x a

  • 第8题:

    对于概率P(A∪B)的意思是( )。

    A:P(A∪B)=P(A)+P(B)-P(A∩B)
    B:P(A∪B)=P(A)+P(B)-P(AB)
    C:P(A∪B)=P(A)+P(B)+P(A∩B)
    D:P(A∪B)=P(A)+P(B)+P(AB)

    答案:B
    解析:
    指的是A发生的概率或者B发生的概率之和,并不包括AB同到发生的概率,所以P(A∪B)=P(A)+P(B)-P(AB)。

    以下可以将变量A、B值互换的是(  )。
    A

    A=B:B=A

    B

    C

    A=(A+B)/2:B=(A-B)/2

    D

    A=A+B:B=A-B:A=A-B


    正确答案: A
    解析:
    A项,只有两个变量无法相互换值;B项,执行后A,B变量的值都是C的值;C项,执行后A,B中的值不是任一个原来的值了;D项,变量A,B的和减B的值得到A的值,赋给了B,此时B中是原来A的值了,然后A,B的和减去现在B的值,即减去原来A的值等于原来B的值,赋给A,这样A,B的值就交换了。

    D.σb:a>b>c,E:b>a>c,δ:b>c>a

    答案:B
    解析:
    本题是关于材料力学性能的概念题,关键是要对材料的强度极限σb、弹性模量E和延伸率δ能正确地理解,σb是应力-应变曲线最高点的纵坐标,E是应力-应变曲线中直线段的斜率,因此σb、E的大小很容易判断,而延伸率δ是拉断后材料的残留的塑性应变,要判断 不同材料延伸率的大小应在σ-ε曲线上各材料拉断点作直线段的平行线,该平行线在ε轴上所截取的线段即为延伸率。所以正确答案应选B
