The mutual interferences of the elements were corrected by Alpha coefficient method.
采用经验系数法解决了元素间的相互干扰。
It is fairly easy to measure a friction coefficient by putting an object on an incline and by changing the angle of the incline, increasing it This is the angle alpha.
测量摩擦系数有一种简单方法,把物体放置在斜面上,然后不断增加斜面的倾斜度,这是角α
So you should be able to calculate what the friction coefficient is using the equation tangent alpha equals mu s.
你们则需要学会,计算摩擦系数,使用μ静=tanα这个公式。
Cronbach Alpha was 0.876, split-half reliability coefficient was 0.841.
问卷的同质性信度系数为0.876，分半信度系数为0.841。
Cronbach Alpha was 0.876, split-half reliability coefficient was 0.841.
