Here the wire is usually matched to the glass which is inside of the bore of a strong metal part with higher coefficient of thermal expansion.

Famous quotes containing the words compression and/or seal:
“Do they [the publishers of Murphy] not understand that if the book is slightly obscure it is because it is a compression and that to compress it further can only make it more obscure?”

Has not yet begun
To make a seizure on the light,
Or to seal up the sun.”
