An electric charge regarded as concentrated in a mathematical point, without spatial extent.
〔主物理〕点电荷
Example sentencesExamples
The electric field anywhere outside a charged conducting sphere is shown to be exactly equal to that produced by a point charge of equal total charge located at the center of the sphere.
Specifically, a positive point charge at 170 has no effect, but a negative point charge significantly reduces substrate turnover.
This point charge is a dipolar amino acid with its negative electron density directed toward the ionone ring or a negatively charged amino acid with its positive end distal from the [beta] ionone ring.
This further supports the possibility of decreased interaction between the second point charge of the protein and the chromophore.
All the atoms having the same point charge in the above database have been kept equivalent in the RESP calculations.
