Research on the Development of Green Hotels in the Context of Low Carbon Tourism

With the continuous implementation of national measures related to carbon neutrality strategy,the concept of a low-carbon economy has been deeply rooted in people’s hearts.Low-carbon tourism has gradually become an inevitable trend,and the tourism industry is also undergoing orderly transformation and upgrading.To promote the sustainable development of the tourism industry,the tourism and hotel industry should also shift towards a low-carbon and green model.Hotel activities can easily bring related environmental issues,such as energy consumption,garbage generation,ecological pollution,etc.Therefore,building a green hotel will bring huge social and economic benefits to the low-carbon tourism industry.This article will address the above issues and take a low-carbon economy as the starting point,proposing sustainable development strategies and suggestions for green hotels from both the internal and external environment of the hotel,creating a low-carbon management atmosphere,and promoting the low-carbon operation of the green hotel industry.

Mathematical Model of Decarburization of Ultra Low Carbon Steel during RH Treatment

According to the balance of carbon and oxygen, a decarburization model for the RH treatment has been developed. in which the influence of the mass transfer of carbon and oxygen in the liquid steel and the stirring energy (ε) in the vacuum vessel on decarburization rate has been considered. The conclusion that the volumetric coefficients of the mass transfer of carbon is proportional to ε(1.5) is drawn. Industrical experiment proves this model is reliable. The influence of some factors on decarburization rate has been obtained. which can provide directions for RH treatment The decarburization behavior of steel with RH-OB treatment is also studied. The OB-or-not curve, the optimized OB time and OB amount are discussed.

Electrolytic deposition of super-smart composite coating of Zn-V2O5-NbO2 on low carbon steel for defence application

Despite the massive usages of low carbon steel in automobile for engineering components, its corrosion and high friction coefficient in aggressive environment make it limited in service. This paper is aimed at modifying low carbon steel structural component with thin film composite for enhanced mechanical and corrosion properties. The steel structure was electrodeposited with Zn-V_2 O_5 and embedded with varied NbO_2 weight concentration of 6-12 wt % based electrolyte. Scanning electron microscope(SEM) and high optical microscope was used to study the microstructural evolution of the fabricated coatings. The thermal stability of the fabricated coatings was studied in an isothermal furnace at 300 ℃ and 600 ℃ and further characterized using a high tech optical microscope. Potentiodynamic polarization technique was used to investigate the corrosion behavior of the composites in 3.65% NaCl. From the result, the effect of NbO_2 on Zn-V_2 O_5-NbO_2 was massive with improved crystal grain within the coatings lattices. The coating possesses strong metallurgical bonding and good corrosion resistance properties of about 0.315 mm/yr corrosion rate compare to 4.1 mm/yr of as-received sample. No doubt the impact of thermal shock on the resilient characteristics of the composite coating was moderate owing to the stable adherent properties of the deposited coatings.

Cu Partitioning Behavior and Its Effect on Microstructure and Mechanical Properties of 0.12C-1.33Mn-0.55Cu Q&P Steel

Cu, as an austenitic stable element, is added to steel in order to suppress the adverse effects of high content of C and Mn on welding. Based on C partitioning, Cu and Mn partitioning can further improve the stability of retained austenite in the intercritical annealing process. A sample of low carbon steel containing Cu was treated by the intercritical annealing, then quenching process（I＆Q）. Subsequently, another sample was treated by the intercritical annealing, subsequent austenitizing, then quenching and partitioning process（I＆Q＆P）. The effects of element partitioning behavior in intercritical region on the microstructure and mechanical properties of the steel were studied. The results showed that after the I＆Q process ferrite and martensite could be obtained, with C, Cu and Mn enriched in the martensite. When intercritically heated at 800 ℃, Cu and Mn were partitioned from ferrite to austenite, which was enhanced gradually as the heating time was increased. This partitioning effect was the most obvious when the sample was heated at 800 ℃ for 40 min. At the early stage of α→γ transformation, the formation of γ was controlled by the partitioning of carbon, while at the later stage, it was mainly affected by the partitioning of Cu and Mn. After the I＆Q＆P process, the partitioning effect of Cu and Mn element could be retained. C was assembled in retained austenite during the quenching and partitioning process. The strength and elongation of I＆Q＆P steel was increased by 5 305 MPa% compared with that subjected to Q＆P process. The volume fraction of retained autensite was increased from 8.5% to 11.2%. Hence, the content of retained austenite could be improved significantly by Mn and Cu partitioning, which increased the elongation of steel.

Transformation Behavior of Low Carbon Steels Containing Two Different Si Contents

Continuous cooling transformation behaviors of low carbon steels with two Si contents （0. 50% and 1. 35%） were investigated under undeformed and deformed conditions. Effects of Si contents, deformation, and cooling rates on γ transformation start temperature （Ar3）, phase microstructures, and hardness were studied. The results show that, in the ease of the deformation with the true strain of 0. 4, the length of bainitic ferrite laths is significantly decreased in low Si steel, whereas, the M/A constituent becomes more uniform in high Si steel. An increase in cooling rates lowers the Ar3 greatly. The steel with higher level of Si exhibits higher Ar3, and higher hardness both under undeformed and deformed conditions compared with the steel with a lower Si content. Especially, the influence of Si on At3 is dependent on deformation. Such effects are more significant under the undeformed condition. The hardness of both steels increases with the increase of cooling rates, whereas, the deformation involved in both steels reduces the hardness.

Corrosion Behavior of a Low-Carbon Steel in Simulated Marine Splash Zone

Experiments were designed to simulate the corrosion of a low-carbon steel exposed to a marine splash zone. The composition and morphology of the rust were investigated using Raman spectroscopy, X-ray photoelectron spectroscopy, energy-dispersive spectrometry and scanning electron microscopy. Corrosion resistance of the rust films was demonstrated by the electrochemical impedance spectroscopy. The wettability of the steel surface was calculated from the data conceruing the wetting degree and the conductivity. The results showed that, in the initial stage, the products of the outer rust layer were mainly made up of Fe（Ⅲ） oxyhydroxide, while the main component of the inner rust layer was magnetite. With an increase in the corrosion time, the inner rust layer continuously turned into the outer rust layer. In addition, both rust layers became dense, thus playing a protective role with respect to matrix. The existence of the rust layer significantly prolonged the residence time of the seawater on the sample surface, a result that tends to improve the cathodic protection effect for steel structures exposed to marine splash zones.

温度和应变幅对亚稳奥氏体不锈钢S321低周疲劳行为的影响

在室温和650℃的环境下对S321、S321H不锈钢进行了0.5%、0.7%、0.9%应变幅下的低周疲劳试验,并在室温下对S321和S321H开展了多个寿命点的疲劳加载历史试验,结合X射线衍射定量分析测算形变诱发马氏体的含量。结果表明:形变诱发马氏体的生成会导致奥氏体钢持续循环硬化,室温下合金在初次硬化后继续二次硬化,而在650℃下没有形变诱发马氏体生成,合金在初次硬化后进入循环稳定阶段。循环过程中,碳含量越低,形变诱发马氏体含量越多,合金的循环硬化程度更高。两种温度下,两种材料的疲劳寿命在低应变幅下都相差不大,应变幅越大,两种材料的疲劳寿命相差越大,因此,可以考虑服役条件为低应变幅时使用S321不锈钢代替S321H不锈钢。

互联网监管是否更加有效?——不同监管工具下惩罚机制推进企业降碳的效果与实施边界研究

政府有效干预企业生产行为是促进低碳经济发展的重要引擎,政府如何选择监管工具和制定政策措施至关重要。运用Hotelling模型、动态演化博弈模型以及数据仿真模拟,探究在传统监管工具和互联网监管工具下政府对高碳企业实行惩罚机制的有效性。结果表明:在一定条件下政府采取传统监管和互联网监管都能促进企业生产低碳产品;在传统监管工具下实施静态惩罚机制有利于企业采取生产低碳产品的策略行为,且惩罚力度越大,企业趋于生产低碳产品的稳态速度越快,而在互联网监管下实施静态惩罚机制,会出现企业的“逆反”心理,抑制企业生产低碳产品;无论在传统监管还是互联网监管下,实施动态惩罚机制都有利于企业生产低碳产品,但是高强度的惩罚力度较低强度的惩罚力度并未表现出明显的监管优势。论文基于完全理性和有限理性的理论假设,分情境探究惩罚机制在不同监管工具下的实施效果,剖析监管模式与监管政策的适配效应,为政府“因时而异”地干预企业生产行为提供政策建议,有利于推进低碳经济发展。

风险偏好、风险感知对新疆棉农低碳生产行为影响

完善风险管理、引导农户低碳生产是促进农业绿色低碳转型的关键。利用新疆289户棉农调研数据,运用Ordered Probit模型从低碳生产技术的风险和异质性视角实证分析风险偏好、风险感知对棉农低碳生产行为的影响。研究发现:样本棉农的低碳生产行为均值为5.443,处于中等采纳水平。风险偏好在1%水平上显著正向影响棉农低碳生产行为,风险感知在1%水平上显著负向影响棉农低碳生产行为,且在风险偏好与低碳生产行为间起显著负向调节作用。风险偏好和风险感知在异质性棉农中的作用差异较大。风险偏好对高文化程度和高种植经验棉农低碳技术采纳数量的影响更大,风险感知对低文化程度、低种植经验和非兼业棉农的低碳生产行为影响更大。风险偏好对组织和体制异质性棉农低碳生产行为的影响均在1%的水平上显著为正,但合作社棉农的风险感知与低碳生产行为在10%的水平上负相关,风险偏好与风险感知的交互项在10%的水平上正相关;兵团棉农的风险感知对其低碳生产行为无显著负向影响,且不具有调节作用。
