摘　要：以薄皮库尔勒香梨、硬皮山竹为材料，研究水果自身性质及红外脉冲激光标刻参数对标刻效果及标刻后水果贮藏品质的影响，分析了不同果皮含水量、果皮硬度和标刻速度对激光标刻颜色、线宽和连续性的影响，并得到了在相对最优工艺参数下，贮藏期间水果果皮标刻区域的局部形貌、标记稳定性及腐烂情况。结果表明，果皮含水量、果皮硬度及标刻速度对薄皮、硬皮水果标刻效果均有显著影响，且在贮藏期间，标刻区域的标记稳定性较好，对贮藏品质基本无影响。这为探究同种水果个体差异性和不同种水果的自身性质对激光标刻效果的影响提供了一定的借鉴意义。

Abstract: The thin-skinned Korla pear and the hard-skinned mangosteen were used as materials. To explore the effects of fruit properties and infrared pulsed laser parameters on the marking effect and fruit storage quality, the influences of fruit peel water content, fruit peel hardness and laser marking speed on the color, line width and continuity of laser labels were analyzed. And the local morphology, labeling stability and decay of fruit peel marked with optimal processing parameters during storage period were investigated. The results showed that both the water content and hardness of the fruit peel and the laser marking speed had significant influences on the marking effect of thin-skinned and hard-skinned fruits. Besides, the laser labels manifested superior stability during storage with storage quality basically unaffected. It provides a certain reference for exploring the influence of the individual differences of the same kind of fruit and the properties of different kinds of fruit on the laser marking effect.
