| 摘要: |
| 目的 分析三维测量技术在不规则食品接触材料表面积和容积的计算中，相较于常用人工测量方法的应用优势。方法 以7种常见的不规则食品接触材料为例，分别用三维测量技术和人工测量技术测量样品表面积，每个样品平行测定6次，对比2种方法测量结果的准确度和精密度。结果 三维测量技术结果准确度高，精密度为0.0134%~1.63%;人工测量结果的精密度为0.748%~3.04%，其稳定性明显低于三维测量技术。结论 人工测量技术存在测量方法不确定、测量偏差大和测量难度大等缺点;三维测量技术操作简单、结果稳定性高、适用性广，具有广泛的应用前景。 |

| Abstract: |
| The purpose is to analyze and evaluate the application advantages of three-dimensional measurement technology in the calculation of surface area and volume of food contact materials compared with the commonly used manual measurement methods. The surface area of 7 kinds of common food contact materials are measured by three-dimensional measurement technology and manual measurement technology respectively. Each sample is measured six times in parallel, and the accuracy and precision of the two methods are compared. The result shows that the accuracy of three-dimensional measurement technology is better with precision between 0.0134%-1.63%. The precision of manual measurement results is between 0.748%-3.04%, which is significantly worse than the result of three-dimensional measurement technology. Manual measurement technology has the disadvantages of uncertainty of measurement method, large measurement deviation and difficult measurement. Three-dimensional measurement technology has advantages of simple operation, high stability and wide applicability, has a wide application prospect. |
