生成列表{1,3,5,7,…,99}? Range[1,99,2]|Table[k,{k,99,2}]|Range[{1,99},2]|Table[k,{k,1,99,2}]
举一反三
- 基于VB语言,( )是日期型常量 A: "2/1/99" B: 2/1/99 C: D: 2/1/99 E: F: {2/1/99}
- 证明:1/2*3/4*5/6.*99/100<1/10
- 设函数$f(x) = x(x - 1)(x - 2) \cdots (x - 99)$,则$f'(0) = $( ) A: 99 B: -99 C: 99! D: -99!
- 【单选题】反应(1)SO 2 + 1/2O 2 = SO 3 K 1 ø (T); (2) 2SO 2 + O 2 = 2SO 3 K 2 ø (T) A. 1 ø (T)与K 2 ø (T)的关系是 B. K 1 ø = K 2 ø C. (K 1 ø ) 2 = K 2 ø D. K 1 ø = (K 2 ø ) 2 E. 2K 1 ø = K 2 ø
- 已知下列反应N2(g) + 3H2(g) = 2NH3(g) (1)1/2N2(g) + 3/2H2(g) = NH3(g) (2) 1/3N2(g) + H2(g) = 2/3NH3(g) (3)的平衡常数分别为 Kθ1 、Kθ2 、Kθ3 ,则它们的关系是 A: Kθ1=Kθ2=Kθ3 B: Kθ1 = (Kθ2)2 = (Kθ3)3 C: Kθ1 =3/2Kθ2 =2/3Kθ3 D: Kθ1 = (Kθ2)1/2 = (Kθ3)1/3
