利用高光谱成像技术和多变量校正方法检测苹果的硬度赵杰文，陈全胜，Saritpom Vittayapadun91，Sumpun Chaitep2(1．江苏大学食品与生物工程学院，镇江212013。
2．Faculty of Engineering, Chiang Mai University ,Chiang Mai 50200，Thailand)．摘要：高光谱图像集图像信息与光谱信息于一身，应用于农产品品质无损检测领域。
该研究尝试利用高光谱图像技术结合多变量校正方法检测苹果硬度的可行性。
试验通过获取的高光谱图像中提取有效的光谱信息来建立预测苹果硬度的预测模型。
在建立模型过程中，偏最小二乘(PLS)和支持向量回归(SVR)两种多变量校正方法被比较，结果表明在785．1l～872．45 nm 范围内，SVR模型的性能优于PLS模型，模型对硬度预测结果的相关系数为0．6808。
试验结果表明高光谱图像技术可以被用来检测苹果的硬度。
关键词：光谱分析; 图像处理; 水果; 硬度; 检测0 介绍水果内部品质的非破坏性可靠评估是研究国家提高其出口潜力的重要领域。
水果的硬度是出口新鲜水果的重要因素。
水果硬度是用来决定苹果质量的重要品质参数之一，也是给新鲜水果分级的主要品质参数。
如今，破坏的Magness-Taylor(MT)硬度检测器被常规地用于测量水果硬度。
已经有大量的研究报告了利用非破坏性机械感应技术，包括准静态力量/变形，冲击力和声学来测量水果硬度。
但是，这种质量检测方法经常是破坏性的，低效率和耗时的，而且倾向于操作性的。
因此，能够测量质量参数，包括苹果的硬度的非破坏性感应技术将在为消费者保证一贯的高质量水果方面具有很大的价值。
如上所述，现在为出口市场的苹果分类分级的方法需要更科学的手段来改进。
这个问题可以由对水果内部质量的非破坏性评估来解决。
各种研究人员已经就各种用来决定采收后的园艺作物质量的非破坏性感应技术的发展做了报告，包括机械力/变形，音波的，冲击力，光学和电器科学的发展。
陈正伟-《宏观经济统计分析（本科）》2016年习题精解重庆工商大学陈正伟一、名词解释（每小题2分，共10分）1．宏观经济统计分析：宏观经济统计分析是指以宏观经济理论指导，对国民经济运行过程及其整体所进行的实证经济统计分析。
2．消费需求弹性系数：消费需求弹性系数是一个较为具体地反映消费需求对经济增长的影响作用或制约性的分析指标。
它是经济增长率与消费需求增长率之比，说明消费需求每增长1个百分点能带动经济增长的比例关系。
3．内在传导机制：是指经济系统内部结构特征所导致的对冲击的反应。
这是一种内部缓冲机制或自调节机制，在数学形式上表现为分布滞后关系，反映了经济周期的内生性，即经济波动的自我推动。
4．全社会固定资产投资：是指是以货币表现的建造和购置固定资产活动的工作量。
是已实现的全社会固定资产投资额。
简称为固定资产投资需求。
5．通货膨胀的收入分配效益：是指在通货膨胀过程中，一部分人从收入中得到好处，一部分人则遭到损害的结果。
