| Abstract: | The factors were studied that affect reacting time of hole pressure of a probe measuring water flow field. The reasonable parameters of combined probe measuring system was presented. The influence was analysized of probe hydraulic resonance and bending under circufluent drag on the measurement. The countermeasures were advanced to improve the measuring precicion. |
