摘　　要：利用力敏传感器的电压输出特性与受力之间的关系结合静力称衡法,从理论上推导出了测量细丝直径的公式,然后设计出了相应的实验方案并进行了验证.利用该公式测量出的细丝直径与常规方法测量出的细丝直径相比较,二者的测量结果相差甚小,说明测量细丝直径的方案确实可行.这种测量细丝直径的新方法,在实际生活和教学科研方面有一定的参考和应用价值.Paper is based on the voltage output characteristics of force sensor and static balance method,the formula of measuring filament diameter is deduced theoretically,and then the corresponding experimental scheme is designed and verified.Compared with the filament diameter measured by the conventional method,the difference between the filament diameter measured by the formula and the scheme is very small,which indicates that the scheme of measuring the filament diameter is feasible.This paper provides a new method to measure the diameter of filament,and has a certain reference and application value in real life,teaching and scientific research.
