Both viruses are good approximations of dielectric objects .
这两种病毒都与电介质物体很相似。
First , they say , it must approximate a dielectric object so that it is very transparent but still refracts light .
他们说，首先它必须近乎电介质物体，这样，它很透明但仍能使光折射。
There are two main types of electroactive polymer ( eap ) , which are usually referred to as ionic and dielectric ( see diagram ) .
电活性聚合物（eap）主要有两种类型，那就是我们通常所说的离子型和电介质型（见下图）。
Although sri researchers have shown that it is possible to use artificial muscles to convert kinetic energy into electricity , getting the process started has always been a bit of a problem , because dielectric eaps need a small initial charge in each cycle .
To control the speed at which it flows through the pore , researchers developed a device that has a multilayer metal and dielectric structure , says steve rossnagel , a researcher at ibm 's watson lab in new york .
