为提升打叶复烤成品片烟的均质化水平,降低烟碱变异系数,按照逐框检测的原则,对分选后所有等级原烟均进行近红外光谱整框检测,根据检测的烟碱含量,把各等级选后原烟分区间进行分类码放,待整个批次均选叶完成后,根据各区间烟框数目进行... 为提升打叶复烤成品片烟的均质化水平,降低烟碱变异系数,按照逐框检测的原则,对分选后所有等级原烟均进行近红外光谱整框检测,根据检测的烟碱含量,把各等级选后原烟分区间进行分类码放,待整个批次均选叶完成后,根据各区间烟框数目进行配比搭配投料,减小各投打单元的烟碱含量差异,最终起到降低成品片烟烟碱变异系数的作用。经检测,成品片烟烟碱变异系数为2.60%,较离线抽检的加工方式变异系数降低了0.64百分点,降幅达19.75%。该方法对降低成品片烟烟碱变异系数具有明显作用,有效提高了成品片烟加工质量。 展开更多

In the actual idioms teaching, most students feel that idioms are difficult to comprehend, memorize and make actual application just because the overall meanings of idioms are unpredictable. Since cognitive linguistics is based on embodiment, it can change the abstract things into comparatively concrete things, which provides a shortest way to grasp these idioms. Actually, most idioms are based on conceptual metaphor and metonymy composed of conceptual mappings between the source domain and the target one. Therefore, this paper is trying to probe into the role of cognitive principles in idioms teaching, especially animal idioms from the contrastive analysis on Chinese "hu" idioms and English "lion" idioms. 展开更多

With the advent of the era of cloud computing, the high energy consumption of cloud computing data centers has become a prominent problem, and how to reduce the energy consumption of cloud computing data center and improve the efficiency of data center has become the research focus of researchers all the world. In a cloud environment, virtual machine consolidation(VMC) is an effective strategy that can improve the energy efficiency. However, at the same time, in the process of virtual machine consolidation, we need to deal with the tradeoff between energy consumption and excellent service performance to meet service level agreement(SLA). In this paper, we propose a new virtual machine consolidation framework for achieving better energy efficiency-Improved Underloaded Decision(IUD) algorithm and Minimum Average Utilization Difference(MAUD) algorithm. Finally, based on real workload data on Planet Lab, experiments have been done with the cloud simulation platform Cloud Sim. The experimental result shows that the proposed algorithm can reduce the energy consumption and SLA violation of data centers compared with existing algorithms, improving the energy efficiency of data centers. 展开更多

The importance of stakeholder relationship management for successful integration in post-merger management is not doubted. The establishment of a new powerful trend in investments produces strategic shifts in strategic management. Shareholder wealth maximization way of thinking is changing to stakeholder wealth maximization where a company's value management system is based not only on economic profit maximization, but also on environmental, social, and governance (ESG) maximization. There is especially a high need for a management system that can be used by mergers and acquisitions (M&A) practitioners during integration process. There is a critical need for metrics which can trace the interests of all stakeholders, because to achieve success in integration, it is no longer acceptable for management to focus solely on the needs of one or two stakeholder groups. In this article, the authors have introduced two frameworks: sun cube and stakeholder relationship matrix. These tools can be useful in mergers and acquisitions (M&A) process for conducting a stakeholder analysis. 展开更多

Carbon-motivated border tax adjustment (BTA) aims to compensate for the loss of competitiveness of carbon intensive products due to carbon dioxide abatement actions. Based on the analysis of the international background of carbon-motivated BTAs, this paper discusses the fundamental motivation leading to US policy transformation, the potential impacts of the policy on China's manufacturing industries, and the compatibility of the policy to WTO rules. Carbon-motivated BTAs violate the fundamental principle of the UNFCCC, and potentially conflict with the core WTO principle of non-discrimination reflected in the GATT Articles 1 and III. However, Article XX of the GATT may be applicable. Thus, the author suggests several measures to alleviate the impacts of carbon-motivated BTAs, and puts forward countermeasures based on carbon consumption per capita. 展开更多

As a complex social ecosystem network,the area along the Grand Canal has a prominent contradiction between the demand for economic development and the protection of natural resources,which means that there is an urgent need for ecological restoration and environmental protection.Using ArcGIS,Conefor,Linkage Mapper and other software platforms,this paper developed an integrated analysis framework,through loose coupling of the attribute-function-structure index system and a series of methods such as the least cost path,circuit theory and moving window search.Based on the framework,we resolve a series of scientific issues in developing regional ecological networks,such as the selection of ecological sources,the simulation of potential ecological corridors,the assessment of the importance of ecological sources and corridors,and the identification of key ecological nodes.Moreover,an overall conservation pattern of the regional ecological network is constructed.The results show that:1)A total of 88 important ecological sources are identified in the study area.The patches with high centrality values are mainly concentrated in the southern mountainous area and the areas with abundant rivers and lakes.2)A total of 138 important ecological corridors are identified,and they are not evenly distributed.Extremely important corridors mostly appear between important patches,and very important corridors are mainly distributed in the central area.3)Fifteen ecological pinch points are extracted,and they are mainly concentrated in the northern part of the study area and eastern Zhejiang Province.The barriers are mostly concentrated in the southern and northern parts of the study area.4)Combining the demands of ecological protection and socioeconomic development,we propose an overall ecological conservation pattern of"one axis,five sections,multiple cores and multiple nodes"to effectively guide future ecological restoration work.These results can provide a useful reference and spatial guidance for decision makers in terms of ecological restoration and cooperation on cross-regional ecological protection along the Grand Canal. 展开更多

Facing the impacts of climate change and the ecological environmental problems caused by urbanization, urban-rural resilience is a new value goal of territorial space development. Blue-green space is an interconnected network system of natural and artificial green space and water bodies, which can dissolve the internal and external pressures of the system by way of mitigatory acceptance and adaptive interaction, reduce the impact of climate change and artificial construction disturbances, and provide diversified composite functions. By recognizing the connotation of the concept of blue-green space, its composite ecological functionality and its relationship with the value of urban-rural resilience, this paper constructs a conceptual framework for the integrated planning of blue-green space in urban and rural areas with “resilient objectives, resource identification, integrated configuration,differentiated regulation”. The paper proposes an integrated and coordinated multi-scale practicable approach of blue-green space planning(i.e., the construction of the blue-green corridor network, the configuration of blue-green open space, the allocation of blue-green infrastructure) and the regulation-based urban-rural transect, with the aim of improving the hydroecological performance and composite functional services in order to realize urban and rural resilience. 展开更多
