一、接触器的定义和基本特点 接触器是指用于频繁地、远距离地、接 通和分断带有负载的主电路或大容量控 制电路的自动切换电器。其主要控制对 象是电动机,也可用于控制其它电力负 载,如电热器、照明灯、电焊机、电容 器组等

电力机车作为电气化铁道的牵引动力,为充分发挥其功率,提高运输能 力,要求机车的牵引力和速度均能在宽广的范围内均匀而经济地调节。一般情 况下机车牵引列车的整个过程是由停车状态开始经过起动加速再逐渐提高速 度,直到机车工作在其自然特性上,此后司机根据列车运行图的要求及线路纵 断面的变化随时进行速度调节

1.已知前提:(1)如果x与y是同班同学,则x的老师也是y的老师;(2)小李和小 张是同班同学;(3)王先生是小李的老师,运用自然演绎推理证明:王先生也是小张 的老师 证明:首先定义谓词: Teacher(x, y) x是y的老师 Classmates(x, y) x和y是同班同学 则已知的前提可以符号化为 (1)VxVyV=Teacher(x, y)A Classmates (, =)>Teacher(x, =))

联立方程组的结构性方法是用经济理论来建立变量之间关系的模型。但 是,经济理论通常并不足以对变量之间的动态联系提供一个严密的说明。并 且,内生变量既可以出现在等式的左端又可以出现在等式的右端使得估计和 推断更加复杂
