Electrons and protons are forms of ordinary matter, but positrons are antimatter particles.

电子和质子构成了普通物质，但正电子是反物质粒子。

They think they have seen an abundance of high-energy positrons, the antimatter versions of electrons, coming from space, and they speculate that this, too, is a sign of dark matter.

他们认为他们在宇宙中发现了大量高能量的正电子。正电子是电子的反物质形式。他们推测这也是暗物质存在的一个证据。

Indeed, the team found that, at the highest energies they could measure, the ratio of positrons to electrons was far higher than at lower energies.

实际上，该研究团发现，在他们所能测量的高能范围内，正电子与电子的比例要比低能范围内的高得多。

Furthermore, the properties of polarons in polar crystals are investigated by taking account of the influence of pressure effect and the electrons emitting or absorbing many virtual phonons.

In organic light-emitting devices, the electrons and holes are injected into the polymer from the electric diodes and then they form negative and positive polarons.

在有机发光器件中，从电极注入的电荷在聚合物链中形成极化子，在电场作用下正负极化子将碰撞、复合形成激子。

In the"strong"electron-phonon coupling limit,the ampli-tude of the frozen-in lattice distortions caused by strong Jahn-Tellercouplingis found to be large enough to localize the itinerant electrons as polarons leading tothe thermally activated conduction behavior above Tc.

这些解是Millis等人的结果在有限的Hunds互作用情形下的推广。
