一、实验目的 1. 学习和掌握三相异步电动机的启动特性 二、实验内容及步骤 ： 本实验利用交流电流表或万用表测量三相异步电动机的输入电流（如图 1-1 I1 和 I2 两点之间的电流）。从而得出三相异步动机的启动特性。 实验步骤 ：

These notes essentially tie up a few loose ends in Lecture 8; in particular, I exhibit examples of inefficiencies in first- and second-price auctions. I would also like to briefly comment on Questions 1 and 2 in Problem Set 2

By and large, I will follow OR, Chapters 1l and 12, so I will keep these notes to a minimum. J Games with observed actions and payoff uncertainty Not all dynamic models of strategic interaction fit within the category of games with observed actions we have developed in the previous lectures. In particular, no allowance was made

1、某水泵以转速n为3600r／min旋转时，相对应的扬程H为128m，流量qV为1.23m3／min， 为满足该流量，拟采用比转数ns为85～133范围的单吸多级泵，试确定所用泵叶轮的级数i? 答案:解：试用2级时，i1＝2，比转速

元素周期表中第 I 族碱金属元素（Li、Na、K、Rb、Cs）与第 VII 族的卤素元素（F、Cl、Br、I）化 合物（如 NaCl， CsCl，晶体结构如图 XCH001_009_01 和 XCH001_010 所示）所组成的晶体是典 型的离子晶体，半导体材料如 CdS、ZnS 等亦可以看成是离子晶体

“If I had to reduce all educational psychology just one principle, I would say this: The most important single factor influencing learning is what the learner already knows. Ascertain this and teach him accordingly
