When the negatively and positively charged streams meet, a complete channel connecting the cloud and the ground is formed.

当带负电和带正电的粒子流相遇时，就会形成一条连接云层和地面的完整通道。

Concentrations of positively charged particles develop at the top and bottom of the cloud, but the middle region becomes negatively charged.

带正电荷的粒子集中在云团的顶部和底部，但中间区域形成的是带负电荷的粒子。

Then updraft wind currents carry the light, positively charged ice crystals up to the top of the cloud.

然后上升气流将轻盈的、带正电荷的冰晶带到云的顶部。

They immersed films made of cellulose acetate butyrate in solutions of phenyl azido and silica (which is positively charged) and phenyl azido and poly-allylamine hydrochloride (which is negatively charged).

In 1966 Kenneth Greisen, Vadim Kuzmin and Georgiy Zatsepin showed that high-energy charged particles (cosmic rays are mostly atomic nuclei, and thus positively charged) should be slowed by collisions with the photons of the cosmic microwave background (radiation left over from the Big Bang that permeates all space).

Those primeval life-forms use a simple type of cellular pump that pushes sodium out of the cell while pulling positively charged protons in.
