摘要
[目的]突破烟叶评级高技能人才在把烟快速定级中的技术瓶颈.[方法]以智能化烟叶分级实训考核系统为数据来源,采用统计学分析法,首次将烤烟42等级在把烟快速定级考试中的出现频率、等级错误率及错误去向进行了量化分析.[结果]等级B2F与B3F、B2R与B3R、C3F和C4F、C3L和C4L这4组等级互为易错,属于易混淆等级;等级X1F、X1L和X2F的错误去向分别为C3F(20.1％)、C3L(35.7％)和C4F(16.5％),属于部位易错等级;X2L和X4L的错误去向分别为X2F(15.8％)和X4F(13.8％),属于颜色易错等级;等级B1L、B2L、C2F、C4F、C2L、X1F、C3V和CX1K的易错等级均为C3F,即C3F是热点等级.[结论]研究结果为有针对性地提升把烟快速定级技能水平提供理论依据.
Abstract
[Objective] To break through the tobacco grading technology bottleneck of high-skilled talents.[Method] Taking tobacco grading intelligent examination system data,used statistical methods first to quantitative analyses flue-cured tobacco 42 grades emergence frequency,error rate and wrong orientation in bundled tobacco fast grading test.[Result] Results showed that,Cos group B3F and B4F,B3L and B4L,C2F and C3F,C2L and C3L,X3F and X4F,B2K and B3K,GY1 and GY2 respectively error to each other,which belonged to the easy confusing grades.Grade X1F,X1L and X2F respectively mistake to C3F (20.1％),C3L (35.7％) and C4F (16.5％),which belonged to the position error-prone grades;Grade X2L and X4L respectively error to X2F (15.8％) and X4F (13.8％),which belonged to the color errorprone grades.In addition,B1L,B2L,C2F,C4F,C2L,X1F,C3V and CX1K all error to grade C3F,which suggested that C3F was the hot spots grade.[Conclusion] The research provided theoretical basis for tobacco grading skill levels.
