The paper gives an exact formula for determining the intensity of an optical field at the center of a spherical particle of arbitrary radius obtained by evaluating an indeterminate form of the 0/0 type of Mie theory for the electric‐field components at the center of the sphere. This formula...
Suppose a point charge is located at the center of a spherical surface. The electric field at the surface of the sphere and the total flux through the sphere are determined. Now the radius of the sphere is halved. What happens to the flux through the sphere and the magnitude of the ...
摘要: An explicit formula for the time required for the center of an initially uniformly heated sphere to attain a given temperature due to thermal diffusion is given in terms of the radius and a temperature parameter.关键词: Theoretical or Mathematical/ heat conduction/ radial heat flow ...

Geometry. the middle point, as the point within a circle or sphere equally distant from all points of the circumference or surface, or the point within a regular polygon equally distant from the vertices. Antonyms: edge a point, pivot, axis, etc., around which anything rotates or revolves:...
The meaning of CENTER is the point around which a circle or sphere is described; broadly : a point that is related to a geometrical figure in such a way that for any point on the figure there is another point on the figure such that a straight line joini
the sphere must be thought of as seen from its centre. The field of vision or of thought is like a sphere whose radii proceed from one’s self in every direction, and extend out into space, opening up boundless vistas all around. It is the symbolical circle of Pascal and the Kabalists...
center of mass, the point at which all the mass of a body may be considered to be concentrated in analyzing its motion. The center of mass of a sphere of uniform density coincides with the center of the sphere. The center of mass of a body need not be
