capture ratio

A sail several kilometers on a side would have fairly good "capture ratios".

Capture ratio refers to the tuner's ability to separate stations broadcasting on the same frequency.

The capture ratio listed in the specs tells how much stronger one of the two conflicting signals must be to bring about this complete separation.

The measurement of how well a receiver can reject a second signal on the same frequency is called the capture ratio for a specific receiver.

An exception is the uranium-233 of the thorium cycle, which has a good fission/capture ratio at all neutron energies.

Intermediate-energy neutrons have poorer fission/capture ratios than either fast or thermal neutrons for most fuels.

The better to cope with such exigencies, listeners in this situation would do well to check the selectivity and capture ratio of any tuner they plan to buy.

The general manager, Dwane Martin, puts it in terms of the "capture ratio," or the percentage of people making inquiries who end up booking events or rooms.

For example, a capture ratio of two decibels (an excellent rating, by the way) means that a station need be only two decibels stronger to override interference from another station on the same channel.

However, fast neutrons have a better fission/capture ratio for many nuclides, and each fast fission releases a larger number of neutrons, so a fast breeder reactor can potentially "breed" more fissile fuel than it consumes.

Because the fission to capture ratio of neutron cross-section with high energy or fast neutrons changes to favour nuclear fission for almost all of the actinides, including U-238, fast reactors can use all of them for fuel.

In a nuclear reactor, k will actually oscillate from slightly less than 1 to slightly more than 1, due primarily to thermal effects (as more power is produced, the fuel rods warm and thus expand, lowering their capture ratio, and thus driving k lower).
