作为供给侧结构性改革的先行者,中国钢铁行业积极化解过剩产能,彻底取缔“地条钢”,2016—2017年化解钢铁产能超过1.2×108t,清除“地条钢”等违法产能1.4×108t。当前,全球钢铁工业处于产能过剩周期,中国钢铁消费由持续增长向“峰值平台区”转变,单位GDP粗钢消费强度回落,单位投资粗钢消费强度下降,预计到2025年国内粗钢消费需求量为6×108~6.5×108t,产量为6.5×108~7.0×108t,到2030年,国内粗钢消费需求量为5.3×108~6.0×108t,产量为5.9×108~6.5×108
t。与此同时,我国废钢资源供给量将快速增加,未 来充足的废钢资源将是我国钢铁工业强有力的支撑,铁素资源构成也将发生重大变化,国际铁矿石资源的需求量将逐步下降,同时对于推动生态文明建设和绿色发展具有重要作用。Biomedical sensor technologies on the platform of mobile phones

Biomedical sensors have been widely used in various areas of biomedical practices, which play an important role in disease detection, diagnosis, monitoring, treatment, health management, and so on. However, most of them and their related platforms are generally not easily accessible or just too expensive or complicated to be kept at home. As an alternative, new technologies enabled from the mobile phones are gradually changing such situations. As can be freely available to almost everyone, mobile phone offers a unique way to improve the conventional medical care through combining with various biomedical sensors. Moreover, the established systems will be both convenient and low cost. In this paper, we present an overview on the state-of-art biomedical sensors, giving a brief introduction of the fundamental principles and showing several new examples or concepts in the area. The focus was particularly put on interpreting the technical strategies to innovate the biomedical sensor technologies based on the platform of mobile phones. Some challenging issues, including feasibility, usability, security, and effectiveness, were discussed. With the help of electrical and mechanical technologies, it is expected that a full combination between the biomedical sensors and mobile phones will bring a bright future for the coming pervasive medical care.
