- Abstract:
- Based on the definition of the continuity of calculus, a new processing perspective to infinitesimal method in the medical
physics was put forward with the use of equivalent treatment. A simple and systematic derivation of the measuring principle of
Ostwald viscometer was achieved with the infinitesimal method. In addition, the physical analysis in the derivation also declared
that the designer of this instrument skillfully used the gravity differential pressure to realize the application of Poiseuille formula
in the vertical tube, which clarifies some misjudgements in the relevant literatures.
