“频率”这个词在不同的学科中有不同的解释,比如在数学里概率论是这样解释的:在相同的条件下,进行了n次试验,在这n次试验中,事件A发生的次数nA称为事件A发生的频数.比值nA/n称为事件A发生的频率,并记为fn(A).
⒈当重复试验的次数n逐渐增大时,频率fn(A)呈现出稳定性,逐渐稳定于某个常数,这个常数就是事件A的概率.这种“频率稳定性”也就是通常所说的统计规律性.
⒉频率不等同于概率.由伯努利大数定理,当n趋向于无穷大的时候,频率fn(A)在一定意义下接近于概率P(A).
数学的解释往往能包含所有的意思,当然我们平时生活中最通俗的解释是:频率是单位时间内重复一个过程的次数,等于单位时间除以周期.
本文主要是介绍一下有关的在频率方面有关的知识,创新,专利成果以及本人对频率创新的思索.
"Frequency" appears in the different disciplines,there are different explanations,for example,in mathematics,probability theory to explain this:under the same conditions,the n-th test,n,in this experiment,the number of incidents A A nA called the incident frequency.Ratio nA / A n called the incident frequency,and recorded as fn (A).
Repeat the test ⒈ when n is gradually increasing the number,frequency fn (A) emerged stability,gradually stabilized to a certain constants,the constant A is the probability of events this "frequency stability" is usually said statistical regularity.
⒉ frequency does not equal probability.Majority from Bernoulli's theorem,when n tends to infinity when the frequency fn (A) in a certain sense under closer probability P (A).
Mathematical explanation can often contain all means,of course,we live in peacetime the most common explanation is:frequency units is a process repeated time the number of equivalent units divided by the cycle time.
This article is to introduce the relevant frequency in the knowledge,innovations,patents,as well as the results of the frequency of innovation,I think.
