Formation of the tricyclic μ4-CC11H12 ligand is consistent with a carbene-type addition of one of the C2 carbons in 1 to a C C double bond of the cyclopentadiene, followed by ring enlargement.DOI: 10.1016/0022-328X(93)83095-D
给出随机的三个数,先取这三个数的绝对值,最后求取绝对值后的三个数的平均值。 C语言 库函数 fabs() 函数的描述:C 库函数 double fabs(double x) 返回 x 的绝对值 函数的声明:double fabs(double x); 参数的说明:x -- 浮点值 核心思路 利用C语言中 math.h 头文件中的 fabs 函数求出三个随机数的...
