某幼儿园按如下方法依次给A,B,C,D,E五个小孩发糖果。将全部糖果的一半再加二分之一块糖果发给第一个小孩;将剩下糖果的三分之一再加三分之一块糖果发给第二个小孩;将剩下糖果的四分之一再加四分之一块糖果发给第三个小孩;将剩下糖果的五分之一再加五分之一块糖果发给第四个小孩;将最后剩下的11块糖果发给第五个小孩。每个小孩得到的糖果数均为整数。试确定原来共有多少块糖果?每个小孩各得到多少块糖果? 要求结果的输出格式为 sum=糖果总数 xa=A得到的糖果数 xb=B得到的糖果数 xc=C得到的糖果数 xd=D得到的糖果数 xe=E得到的糖果数

Expert Choice represents a significant contribution to the decision making process 工t assists a decision maker in solving complex problems involving many criteria and several courses of action . An Expert Choice solution to a problem reflects the expertise of the decision maker , not the computer . Behavioral scientists have spent many years studying the human mind and how it makes decisions . They have found that humans are influenced by their previous experiences and this causes them to have biases . Basic instincts , preferences and environmental factors also play key roles in how we analyze data and make decisions . There 15 way to remove these factors from human decision making , nor would we necessarily want to , but as the problems of our world become more and more complex , it 15 necessary for us to employ a framework to help make more logical and less biased decisions while still taking our feelings and intuition into consideration .

开关磁阻电机调速系统的主要研究 “开关磁阻电机(Switched reluctance motor简称SR电动机)”一词源见于美国学者S.A.Nasar1969年所撰论文,它描述了这种电机的两个基本特征:1开关性——电机必须工作在一种连续的开关模式,这是为什么在各种新型半导体器件获得后才得以发展得主要原因;2磁阻性——它是真正的磁阻电机,定、转子具有可变磁阻回路。

动态扫描显示接口 动态扫描显示接口是单片机中应用最为广泛的一种显示方式之一。其接口电路是把所有显示器的8个笔划段a-h同名端连在一起,而每一个显示器的公共极COM是各自独立地受I/O线控制。CPU向字段输出口送出字形码时,所有显示器接收到相同的字形码,但究竟是那个显示器亮,则取决于COM端,而这一端是由I/O控制的,所以我们就可以自行决定何时显示哪一位了。而所谓动态扫描就是指我们采用分时的方法,轮流控制各个显示器的COM端,使各个显示器轮流点亮。
