Webb23 mars 2015 · 希腊字母中确实有几个字母除了大小写以外还存在第三种字符，下面举几个例子。. 图中的 Θ（theta）、Σ（sigma）、Φ（phi） 三个字母，左边是大写，中间是小写。. 至于右边，一般用作符号或其他特殊用途。. 例如“ς”专用于词尾，“ϕ”（U+03D5）在理工 … Webbφ (n) = n Π (1 - 1/p j ), where the p j 's are the prime factors of n. For example, the prime factors of 12 are 2 and 3. If we use the product formula above to compute φ (12), we get φ (12) = 12 Π (1 - 1/p j) = 12 (1 - 1/2) (1 - 1/3) = 12 (1/2) (2/3) = 4. Properties of φ (n) If p is prime then φ (p) = p-1.

The most common interpretation of the magnitude of the Cramér’s V is as follows: Small Effect Size: V ≤ 0.2; Medium Effect Size: 0.2 < V ≤ 0.6; WebbThe motor power factor is the phase angle between voltage and current (cosφ). cos phi (φ) is used, among other purposes, to calculate the power consumption of a motor. Power consumption is of high importance for pumps. For pumps with standard AC motors, the power input is found by measuring the input voltage and input current and by reading ... simplicity crib with attached changing table
