Discussion of Inflexion Question in Course of Measuring Surface Tension Coefficient by Force Sensor / 医疗卫生装备

ABSTRACT

Objective To discuss the inflexion question in the course of measuring surface tension coefficient.Methods Metal frames with different lengths,radials and metal cylinders with different inside & outside radials were used to measure the inflexion.Results The inflexion appeared in the course of measuring surface tension coefficient by using force sensor and the inflexion changed with the different radials and lengths of the metal frames.Conclusion The thickness and bending of the fluid membrane results in the change of inflexion,and the inflexion can be avoided with the length and radial chosen properly.
