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 .

尽管斯坦福国际研究院的研究人员已经证明用人造肌肉将动能转化成电能是有可能的，但启动这一转换过程时总有些麻烦，因为每个电介质电活性聚合物环都需要少量的原始电荷。

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 .

为了控制它通过孔的速度，研究人员发明了一种装置，该装置有一个多层金属和电介质结构，ibm在纽约的沃森实验室的研究员steverossnagel说。
