摘要：Empowering the value realization of ecological products with a digital economy is an important path for achieving the transformation of“two mountains”and the construction of ecological *** on the panel data of 30 provinces in China from 2011 to 2022,a fixed-effects model was used to empirically test the impact,heterogeneity and mechanism of the effects of the digital economy on the value realization of ecological *** analysis revealed three key findings.(1)The digital economy has a significant driving effect on improving the ability to realize the value of ecological products,and this effect is still applicable in a variety of robustness tests such as shrinking the years,replacing explanatory variables,and endogeneity tests.(2)The rise of the digital economy affects the value realization of ecological products to different degrees in different regions,especially in the eastern region,while the effect in the central region is not obvious.(3)The analysis of mechanistic variables indicated that the digital economy has an impact on the value realization of ecological products through the development of green finance and government ***,the government should design differentiated and multi-level support policies for the realization of ecological product value according to the heterogeneity of natural resources,ecological potential and the levels of digital economy development in different regions,and it should strengthen the control of non-environmental protection behaviors of the *** should accelerate the digital transformation of the entire production,distribution,circulation and consumption chain of ecological products,and actively develop financial products and services that meet the characteristics and needs of ecological products.

摘要：基于双平面模型的四维光场表示形式,光场相机以牺牲图像空间分辨率为代价,实现了三维场景空间信息和角度信息的同步记录。为了提高光场图像的空间分辨率,本文搭建了基于双路引导更新机制的光场图像超分辨率重建网络。网络前端以不同形式的图像阵列为输入,构建残差串并联卷积实现了空间、角度信息解耦合。针对解耦合后的空间、角度信息,设计了双路引导更新模块,采用逐级增强、融合、再增强的方式,完成空间信息与角度信息的交互引导迭代更新。最后将逐级更新后的角度信息送入简化后的残差特征蒸馏模块,实现数据重建。对比实验表明,所提网络在有效控制复杂度的基础上,获得了更好的超分性能。

摘要：为解决无省旗袍现有纸样结构设计方法存在参数杂糅难以理解和演绎,以及较为依赖主观判断等问题,提出了一种无省旗袍的结构设计方法。通过博物馆实地走访、观察,专家问题访谈,对款式内涵和特征进行深入理解和把握;筛选典型的无省类旗袍款式样本,结合叠图分析方法对衣身腰身特征和衣袖肩线特征进行归类分析,总结得到2类典型款式;针对2类典型款式进行结构设计与实验研究,结合东华服装结构设计理论提出无省类旗袍的纸样设计方法,并选取6名不同体型的受试者进行样衣实验,包括静态穿着实验和动作活动实验。实验结果表明,通过该方法制作而成的样衣,在2种状态下均达到了较好的穿着效果,从而验证了此方法的可行性与可演绎性。

摘要：为了解芋头压缩和切削力学特性,以山东小芋头为试验样本,利用TMS-PRO食品物性分析仪对芋头样本进行压缩试验,计算得出芋头失效应变和弹性模量等参数。利用定制刀具,对芋头在不同切削厚度、不同刀具刃角、不同刀具滑切角情况下进行切削试验,测得切削过程中最大切削力,运用SPSS软件分析变化规律。试验得出:所选芋头样本失效应变为0.314,抗压强度为1.490 MPa,弹性模量为4.751 MPa;随着切削厚度增加最大切削力增大,且切削厚度>3 mm后增长缓慢;随着刀具刃角的增加最大切削力增加;随着刀具滑切角的增加最大切削力显著减小。对交互试验结果的方差分析,得出切削厚度、刀具刃角和滑切角均对芋头的最大切削力有极显著影响,切削厚度和刀具刃角的交互作用具有显著影响,切削厚度和刀具滑切角的交互作用具有极显著影响。试验分析结果可为芋头收获和加工等机械的设计、制造提供理论依据。
