Horizontal radiation ducts in research reactors are used to reduce the high energy neutron flux from near the core.

研究堆中水平辐照孔道用以从堆芯附近引出高能中子流。

The result shows: it's effective garments to shield thermal and middle—energy neutron, and available in many places.

表明这是一种能有效地屏蔽热中子和中能中子的防护器具，可用于许多场所。

And you can do it in one-group theory or multi-group theory. One-group theory assumes that the neutron energy and everything is going on at one energy and we have to make some adjustments.

你能够在单群理论或这多群理论里，单群理论假设，中子能量和所有的东西，要达到一个能量，我们必须要做出些调整。

These enormous emissions of energy occur when black holes, neutron stars or white dwarfs collide - the galactic mergers take just seconds, but they send out a vast wave of radiation.

But the scientists are confident the object is a pulsar, rather than a regular neutron star, because of its high-energy emission and the fact that it doesn't show up in optical wavelengths.

This involves injecting boron atoms into the cancerous organ, and using a neutron beam to split them into destructive high-energy particles.
