举一反三
- 图示手摇提升装置,z1=20,z2=50,z′2=15,z3=15,z′3=1,z4=40,z′4=18,z5=54,则传动比i15= 。[img=455x476]1803be1b2a961fb.png[/img]
- 17e0a6f355f2853.png如果z1=15,z2=25,z3=z5=14,z4=z60=20,z7,30,z8,40,z9=2(且为右旋蜗杆),z10=60传动比i1 10应为100
- z=0为f(z)=z^2 (e^(z^2 )-1)的 级零点,
- 调用下面函数,错误的是( )。def f(x, y = 0, z = 0): pass #空语句,定义空函数体 A: f(z = 3, x = 1, y = 2) B: f(1, x = 1, z = 3) C: f(1, y = 2, z = 3) D: f(1, z = 3)
- 执行下面代码,错误的是def f(x, y = 0, z = 0): pass # 空语句,定义空函数体 A: f(1, x = 1, z = 3) B: f(z = 3, x = 1, y = 2) C: f(1, z = 3) D: f(1, y = 2, z = 3)

下面函数定义并调用后,能产生正确结果的是?def f(x,y=5,z=3): pass A: f(5,x=1,z=3) B: f(x=1,y=5,z=6) C: f(1,,z=3) D: f(x=1,2)

intx=5,y=8,z=7;表达式z=!(x>y)||(x=1,y=3)计算后的结果 A: x=1,y=3,z=1 B: x=1,y=3,z=0 C: x=5,y=8,z=0 D: x=5,y=8,z=1

若f(z)在圆|z|<R内解析,f(0)=0,|f(z)|≤M<+∞,则(1)|f(z)|≤;(2)若在圆内有一点z(0<|z|<R)使

设z的初值是3,求下列表达式运算后的z值。(1)z+=z (2)z-=2(3)z*=2*6 (4)z/=z+z (5)z+=z-=z*=z

假设x=5,y=8,则分别执行下列语句后z的值为多少? (1)z=x/y (2)z=x%y (3)z=x+(++y) (4)z=x+(y++) (5)z=x&y (6)z=x|y (7)z=x<<316 (8)z=x>y?x:y
