the central number in a geometric progression (e.g. 9 in 3, 9, 27), also calculable as the nth root of a product of n numbers
几何平均(如3,9,27中的9),等比中项,等比中数。
n. 几何平均;等比中项;等比中数
The geometric mean antibody titer detected with ABC-ELISA was 6.70 times of that detected with standard ELISA.
两法同为阳性的包虫病人中abc法检出的抗体滴度为ELISA法的6.70倍。
The Geometric Mean works better than the median for reporting the best middle task time for sample sizes less than 25.
对于测试样本低于25以下时,几何平均值比中位数能更好的报告最佳任务完成时间中间值。
X is the electronegativity of the semiconductor, which is the geometric mean of the electronegativity of the constituent atoms.
看了半天不知道这个X到底是什么意思?什么叫半导体的电负性…
The mathematical mean of the physical quantity has multiple expressions forms, including arithmetical mean and geometric mean, etc.
物理量的数学平均值有算术平均值和几何平均值等多种表达形式,这些数学平均值所表达的物理含义是不同的。
Construct a right triangle with given hypotenuse c such that the median drawn to the hypotenuse is the geometric mean of the two legs of the triangle.
构造一个直角三角形(斜边c已给定),使斜边上的中线长度是两直角边长度的比例中项。
根号ab,称为几何平均数,这个体现了一个几何关系, 即过一个圆的直径上任意一点做垂线,直径被分开的两部分为a,b, 那么那个垂线在圆内的一半长度就是根号ab,并且 (a+b)/2≥根号ab! 这就是它的几何意思,也是称之为几何平均数的原因。
