【题目】T he motion of a particle p, whose co-ordinates are (r,y) referred to a pair of fired ares through a point o, satisfies the equations(v^2x)/(dt^2)=-ut^2x (x^2y)/(d^2)=-u2yThe initial condtions are x=a, y=0, (-x)/(1-t)=0 and (|xy)/(|d|)=bw when t...
From a consistent expression for the quadriforce describing the interaction between a colored particle and gauge fields, we investigate the relativistic motion of a particle with isospin interacting with a BPS monopole and with a Julia–Zee dyon. The analysis of such systems reveals the existence ...
A small particle floating on a liquid meniscus surface near a vessel wall tends to approach the wall spontaneously. This particle behavior was theoretically investigated. Because of the solid-liquid wettability, an unbalanced force is caused in the tangential direction to the liquid surface and the ...

Quantum mechanics does not provide direct tools for calculating time quantities related to the motion of a particle. In this paper we introduce a meaningful ``time,'' the ``stay time'' in a space region, and we propose a method for calculating its statistical distribution. The stay time is...
Torr. The statistical behavior of the oscillation amplitude is consistent with the theoretical prediction for Brownian motion in a low pressure gas. These measurements constitute the first direct observation of Brownian motion of a levitated particle in an environment below 1 Torr. In addition to the...

The noninstantaneous behavior of the velocity correlation function for a turbulent fluid leads to memory effects in the equation of motion of a particle suspended in such a fluid. This effect is a direct consequence of the fluctuation‐dissipation theorem, which connects the correlation properties of...

The motion of a charged particle in mutually perpendicular electric and magnetic fields is analyzed under the assumption that the magnetic field is plane parallel, single-coordinate dependent, and characterized by strong variation at distances of the order of the Larmor radius. The electric field is...
