高温灰化法检测金属丝面料中金属丝含量

金属丝面料作为新型功能性面料是目前市场上较流行的一款高附加值的面料,一般同等技术水平下,金属丝占的比例越高价格越贵。目前常用的检测手段主要是手工拆分,虽准确但耗时长,效率低,通过建立高温灰化法检测金属丝含量,一次可以处理多个样品,且与手工拆分法有着同样的准确度,精密度也良好,是一个可以广泛应用的检测方法。

An integrated scenario analysis for the metal coating sector in Europe

Although new paint products and technologies have been developed, the sector of paint application still contributes substantially to total volatile organic compound (VOC) emissions. Recent environmental legislation, especially the EU Solvent Emission Directive 1999/13/EC and its transposition into national law, coming into force in 2007, will have an important influence on the sector structure and the associated supply chain, especially for small- and medium-sized enterprises (SMEs). This paper summarises a comprehensive scenario analysis to explore possible future trajectories for the sector. The main focus is on paint application activities, considering in particular the consequences of new environmentally friendly products and technologies which can be used by SMEs. Four different scenarios representing possible future states of the sector are evaluated, taking into account environmental, technical and socio-economic aspects along the associated supply chain and life cycle. The scenarios allow the formulation of recommendations and guidelines for policy makers and industries. This example confirms that interdisciplinary scenario analysis is a suitable approach to investigate possible future development of an industrial sector.     

电感耦合等离子体原子发射光谱(ICP-AES)法测定出口食品级磷酸中铜、镍、铅、锰、镉、钛

我国金属期货市场交叉影响及其传导效应实证

文章通过Granger因果检验、GARCH模型以及广义脉冲响应函数等方法对我国金属期货市场的交叉影响及其传导效应进行了实证研究。研究发现:期铜市场风险最大,期锌次之,期铝市场风险小,而消化信息的能力期锌强,期铜次之,而期铝弱,并从三个不同角度证实了结论。在交叉影响上,目前我国金属期货市场中期铜对期铝和期锌存在双向Granger因果关系,而期铝和期锌仅存在单向Granger因果关系交叉影响不明显。在纵向冲击中,期铜当期波动强烈且持续时间长传导效应强,期铝当期波动小但持续时间长,期锌当期波动较强但持续时间短。在横向冲击中,期铜对期铝和期锌传导效应最大,当期分别达到0.8%和1.7%,期铝价格冲击对期铜和期锌的传导时间最长,持续达14期和12期,而期锌价格冲击对其他金属期货传导效应不明显且持续期短。研究还发现,不同种金属期货间的价格收益对价格波动的交叉影响,如果存在关系则为反向变化的关系。对于上述现象文章结合实际情况给予了一定的解释。

Producing Extreme Metal festivals: An analysis from Lacan's gaze

By employing Lacan's theoretical framework of gaze, this study provides a narrative analysis to examine the managerial experiences of the producers for Extreme Metal festivals. Specifically, it explores meanings and struggles of tourism festival making that connects individual subjectivities and politics of culture production. As such, it offers a broad conceptual framework merging the Lacanian gaze into tourism research and MacCannell's theory. The findings reveal that festival producers are constantly dealing with various contested roles and voices, revealing in-depth psychological complexities situated within managerial experiences. Meanwhile, the process of festival management must be seen as significantly influenced by the mechanism of cultural offering that the producers attempt to assert and define through the festival space. Finally, implications related to the greater realms of psychoanalytic insights and their potential connections with tourism management are discussed.
