Some people believe that there are houses which are haunted by ghosts.

Today we are going to describe a scientific experiment
今天我们要描述一个科学实验,
during which a "ghost"was seen.
实验过程中见到了"鬼".
The "ghost" is really an after-image.
此"鬼"实际上是个余像.
It is called "Swindle's Ghost"
它之所以被称为"斯威特尔鬼魂",
because the experiment was first performed by an American psychologist called Swindle.

A dark,moonless night was chosen and the curtains were drawn

so that no light could enter from outside.
使外边光照不进来.
Half a dozen people were asked to sit round a table in the middle of the room.

A table-lamp was placed in the centre of the table.
桌子的中央放一盏台灯.
When everyone was seated,the lamp was turned off for ten minutes.
待每人就座后,熄灯10分钟.
Everyone sat in complete darkness and looked towards the lamp
大家坐在一片漆黑中朝着灯看,
till they got quite used to the darkness.

They sat perfectly still and kept looking in exactly the same direction.

Then the lamp was turned on for exactly one second and then off again.
然后开灯1秒钟,再关灯.
