摘要: 1. In t roduct ion I is intuitively clear tha an infinite amount of work necessary in order to accelerate a body ~ , initially at rest and surrounded by incompressible viscous fluid which occupies the (three-dimensional) region exterior into state uniform motion with constant velocity, -,~0. For if W(t) done accelerating from initial ime = 0 till t, E (t) kinetic energy particles Q rate converted heat motion, one has always relation (see, e.g., [1, p. 2687), w(t) (0 + f O (*) 3.
