Second, we use Binomial Distribution Function to accomplish the control of difficulty proportion in Adaptive Item Bank System.
第三，采用二项分布函数完成自适应题库系统中难度比例的控制。
By using this method, we deduced the probability generating function of the binomial distribution in the Markov dependent sequence.
利用这一方法推导了在马氏相关序列下的二项分布的概率函数。
