My mother seemed to be able to make dolls (洋娃娃) out of anything. She made some dolls for me and my two elder sisters. I 36 playing with them, but still, secretly, I hoped for a store-bought 37 like the one our rich cousin had. Her doll 38 open and close its blue glass eyes and even say "Mamma". I 39 stopped admiring it and hoping to have one.

However, my dream 40 came true when I was six. One day my father came back from his business trip with three 41 dolls! They were much smaller than our cousin’s doll and their eyes were just painted ones, but I did not 42 such differences. They were 43 "store-bought" dolls. We each chose one and I named 44 Misako.

Soon my sisters and I became 45. Our "children" kept us 46 all day. We gave them a bath, 47 them, brushed their hair, took them out for a walk and put them to bed. Several months later, they got more like real children — their 48 and bodies became dirtier; their dresses got stained; their hair less smooth.

But, by then, 49 interests seemed to have moved into 50 toys. Their dolls were abandoned (被抛弃) and in bad condition. One had 51 one of her arms, and 52 was one-legged. "You can 53 them if you want," my sisters said to me. Thus, I had 54_ dolls. They were more or less handicapped (残疾) and they often looked at me as if they needed me to 55 them. I enjoyed this feeling of being needed — being the only one in the world who could protect them with a lot of love. Indeed, they made the rest of my childhood days very happy.

在暗室的真空装置中做如下实脸：在竖直放置的平行金属板间的匀强电场中，有一个能产生、、三种射线源、从射线   源射出的一束射线垂直于电场方向射入电场，如图所示，在于射线源距离为H高处，水平放置两张叠放着的、涂药面朝下的印像纸（比一般纸厚且坚韧的涂有感光药的纸），经射线照射一段时间后把两张印像纸显形。

(1)上面的印像纸有几个暗斑？各是什么射线的痕迹？

(2)下面的印像纸显出一串三个暗斑，试估算中间暗斑与两边暗斑的距离之比？

(3)若在此空间再加上与电场方向垂直的匀强磁场，一次使射线不偏转，一次使射线不偏转，则两次所加匀强磁场的磁感应强度之比是多少？(已知：)
