作者 刘涛 梁丝柳 《超硬材料工程》 CAS 2018年第1期53-56,共4页
为了研究表面镀层对925银合金首饰中银含量的影响,采用X射线荧光光谱法、电位滴定法、ICP光谱分析法等分析手段对其银含量进行比较研究,结果表明电位滴定法和ICP光谱分析法检测结果基本相符,而镀层残留在压片表面引起的X射线荧光法测试... 为了研究表面镀层对925银合金首饰中银含量的影响,采用X射线荧光光谱法、电位滴定法、ICP光谱分析法等分析手段对其银含量进行比较研究,结果表明电位滴定法和ICP光谱分析法检测结果基本相符,而镀层残留在压片表面引起的X射线荧光法测试结果整体偏高。 展开更多

Large deposits of cement raw material and resources like limestone, gypsum and shales/clays found from the Koh Sulaiman area of South Punjab (Saraikistan) and Balochistan Provinces, Pakistan. The installation of cement industries especially in South Punjab/Saraikistan Province due to close occurrences of resources should develop the area and increase the export. The Koh Sulaiman regions of South Punjab (Saraikistan) have huge gypsum deposits which deserve for further exploitation. Pakistan is agricultural country and fertility of cultivated lands is vital. Fertilizer resources like phosphate deposits are moderate but the deposits of phosphate and potash bearing rocks are very vast and need their further explorations and exploitation in the Indus Basin. Pakistan has very large construction, dimension and decor stone deposits like limestone, marble, dolomite and igneous rocks like granite, dolerite, serpentine, etc. which needs further exploitation for the development of the areas and increase export. Pakistan is spending a lot of earnings for importing glass, glass wares, pottery, clay, etc. while Pakistan has these resources which needs exploitation of own resources. The best structures and geotectonic elements like the Northern and Western Indus Sutures and Karakoram Suture and Indus placers which are rich in gemstones and jewelry resources. To increase gems and jewelry export, these industries requires reduction in gemstones smuggling and encouragement for gem appraisal and jewelry industry at high level for value addition. In short, Pakistan is rich in natural resources but poor in development. Try should be made to develop and export the own mineral commodities like cement, gypsum, marble, gemstones and jewelry. 展开更多

近年来,供应链金融模式在我国迅速发展,已成为解决中小企业融资难题的重要途径。本文从现金-现金流敏感性角度出发,以A股74家轻工制造业上市公司数据为研究样本,通过现金-现金流敏感性模型,验证样本公司是否面临着融资约束以及供应链金... 近年来,供应链金融模式在我国迅速发展,已成为解决中小企业融资难题的重要途径。本文从现金-现金流敏感性角度出发,以A股74家轻工制造业上市公司数据为研究样本,通过现金-现金流敏感性模型,验证样本公司是否面临着融资约束以及供应链金融是否缓解了样本企业的融资约束。实证结果表明,目前我国的轻工制造业上市公司存在显著的融资约束,且并未随着供应链金融的发展而得到有效缓解。该结论为包括珠宝产业在内的轻工制造业供应链金融发展现状提供了实证证据:即目前国内珠宝企业在供应链管理方面普遍滞后,缺乏开展供应链金融业务的基础,且强势品牌企业缺乏承担核心企业扶持上下游中小企业的意愿。在此结论基础上,为珠宝企业如何更好地利用供应链金融解决融资困境提出了相关建议。 展开更多
