The results of negativeresistanceeffect and transient characteristics of a SOI structure prove that the program can correctly simulate the main phenomena caused by self heating effect.
The result shows, under different vibration mode, equivalent parallel capacitance and resistance are not constant value. There is negative damp effect in transducer system at the operating mode.
Objective:In order to observe the effect of negative pressure on vascular elasticity, resistance and bloodflow volume in diabetic patients with peripheral angiopathy.
