When experimental populations are set up under simple laboratory conditions, the predator often exterminates its prey and then becomes extinct itself, having nothing left to eat.

当实验种群在简单的实验室条件下建立起来时，捕食者往往会消灭它的猎物，然后自己也走向灭绝，因为没有东西可以吃。

For example, one of the experiments we do is measure the magnetic field of current coil, and after we do the experiment, we all have a passive visualization that shows the same experimental set-up, except we add to that.

比如，我们做的一个实验就是,测量电线圈的磁场，在我们做完实验之后，我们都感受到了一个直观化的过程,它展现了同样的实验过程，只是那是我们加的。

Meanwhile, Dr Forrest's group has constructed an experimental set-up, described in a paper recently submitted to the Evolutionary Computation Journal, that mimics the way real immune systems identify invading pathogens.

First, if universities are to create centres of excellence they will need greater freedom: for example, to recruit their staff, to set up experimental links with research bodies or to increase enrolment fees.

Moreover, in the few areas of America where one cable company has built over a rival's existing system, where a telephone company has set up an experimental system to deliver television signals, or where there is an old, municipally owned cable system as well as a private one, competition has led to lower prices (see chart).
