摘　　要：应用自制的冲击摆对马铃薯的坚实度进行了检测研究。利用3种不同形状的冲击针头(圆柱型、圆锥型和三棱锥型)作为工作部件,采用电测方法对摆锤摆动角度进行检测,并以此来衡量马铃薯的坚实度。试验所得数据经过spss软件分析,分别得出不同针型的描述性统计分析结果,经过柯尔莫哥洛夫检验,方差检验及利用Scheffe方法进行多重比较。结果表明:利用冲击的试验方法来检测马铃薯的坚实度原理可行,三棱锥型的针头更能真实地反映马铃薯的坚实度,可为其他果蔬产品的坚实度检测提供参考。Impact testing method was applied to measure the firmness of potato.Three different types of needles（cylindrical, conical,triangular pyramid type）as working parts,and angular displacement sensor were used to test pendulum swing angle and measure the firmness of potato.The data were analysed with the spss software and results were obtained for different needles.The Kolmogorov test,variance test and Scheffe method were used in post-examination.The triangular pyramid needle reflected the true firmness of potato more reliably.The results showed that the impact testing method detecting the firmness of potato is practicable. The study could serve other fruits and vegetables as reference.
