"I heard the brushing-off ritual gets rid of all the harmful energy from my body,"

So z equals 7 -- this is the cut-off where, in fact, the sigma orbital is going to be higher in energy than the pi 2 p orbitals.

所以z等于7-这是分界点，实际上，sigma轨道能量,要比π2p轨道高。

z And what you need to remember is if the z 8 is equal to eight or greater, such as oxygen being the cut-off point, this sigma 2 p orbital is actually lower in energy than the pi 2 p orbitals, the molecular orbitals.

你们要记住如果,等于或者大于，就像O是分界点，这时sigma2p轨道,比π2p轨道能量更低。

But the slow decay in radiation intensity from a tabletop pulsar would make possible extremely long-range transmitters, giving far-off space probes an energy-efficient way to beam information back to earth.

ECONOMIST: Physics

Pylons are a necessary evil if we are to wean ourselves off carbon-based energy.

BBC: Landscape impact of electric pylon softened by design?

We believe people everywhere would see their economies crippled by a cut-off in energy supplies.
