反光材料的安全防护作用及发展建议

反光材料是用玻璃微珠或微棱镜材料采用光学折射定向回归原理生产出来的,对人体无放射性及毒副作用.用反光材料制作的警示标牌、服装服饰,比其它非反光材料在灯光照射下醒目几百倍,对保证交通、设备、人身安全有明显的效果,尤其对老年人、儿童、残疾人的行路安全更有特殊的保护作用.     

反光材料的类别与应用

1 前言 反光材料，也称为回归反射材料或逆反射材料，包括反光膜、反光油墨、反光标线漆、反光布、反光革、反光织带和反光安全性丝织物等。其原理是在相应的材料表面上引入一种高折射率的玻璃微珠或三棱镜微晶格结构，将光线按原路反射回光源处，从而形成回归反射现象。在灯光照射下，反光材料具有比其他非反光材料醒目几自倍的视觉效果。

反光材料在警用救援服中的应用研究

高可视性材料在警用救援服装中占有重要地位。本研究是选用国内外最优的两种反光材料,设计不同的温度、压力及时间与阻燃面料粘合,经过耐磨、耐曲挠和耐水洗后,观其反光性能、物理性能和阻燃性的变化,以确定最佳的粘合温度、压力及时间。结果表明:粘合温度为175℃,压力为0.35MPa,粘合时间30S为最佳的条件,在此条件下两种反光材料各项性能均能满足警用救援服装使用要求。     

反光材料与安全防护用品

1 何谓反光材料 它是一种具有将照射其上的光,以一定的强度反射回光源方向的材料,即具有回归定向反光特性的材料。当光线从一定角度入射时,大部分光仍向光源方向回归反射。而且入射光轴与反射光轴是平行的。 通常用逆反射系数(CD/LX·M~2)来评价定向回归反射性能的优劣。一个直径为0.5m,逆返射系数为70CD/LX·M~2的反光

涂布生产中铝粉的安全管理措施

正近几年,铝制品被广泛应用于建筑涂料、汽车、塑料、印刷油墨、反光材料等领域。作为装饰性颜料,可使被涂装的物品绚丽多彩,具有明亮的金属光泽和金属闪光效果。铝粉由于具有一般金属颜料所没有的特性,即铝粉具有银白色光泽,一般金属在粉末状时的颜色多为黑色,作为反光反射层,铝粉在蒸镀、溅镀等领域被广泛应用。但是铝性质活泼,尤其是微细铝粉遇水会快速发生反应释放出氢气和热量,非常危险。最近几年经常见有铝粉自燃、爆炸的事故发生,也有消防处置不当而导致的二次爆炸事故。     

Heat Gain From Thermal Radiation Through Protective Clothing With Different Insulation,Reflectivity and Vapour Permeability

The heat transferred through protective clothing under long wave radiation compared to a reference condition without radiant stress was determined in thermal manikin experiments. The influence of clothing insulation and reflectivity, and the interaction with wind and wet underclothing were considered. Garments with different outer materials and colours and additionally an aluminised reflective suit were combined with different number and types of dry and pre-wetted underwear layers. Under radiant stress, whole body heat loss decreased, i.e., heat gain occurred compared to the reference. This heat gain increased with radiation intensity, and decreased with air velocity and clothing insulation. Except for the reflective outer layer that showed only minimal heat gain over the whole range of radiation intensities, the influence of the outer garments’ material and colour was small with dry clothing. Wetting the underclothing for simulating sweat accumulation, however, caused differing effects with higher heat gain in less permeable garments.     

12Cr1MoVG蒸汽管道蠕变的反射式非线性超声无损检测分析*

针对传统（收-发分置）透射式非线性超声检测方法在现场应用受到众多制约的问题,提出二次谐波（收-发合置）的反射式非线性超声检测思路,通过采集并分离超声检测信号一次底波的反射信号获取非线性超声检测中基波和二次谐波信号,并设计搭建反射式非线性超声实验系统,进行2万小时12Cr1MoVG钢高温蒸汽管道检测实验并与测试样品的里氏硬度值进行比对。研究结果表明:该管道测点的非线性参量β在0.005~0.03变化与其硬度值变化（420~440 HL）呈负相关,即随着试样性能下降β值增大,而硬度值下降。研究结果可为在役高温蒸汽管道蠕变程度的检测提供参考。

On-road measures of pedestrians' estimates of their own nighttime conspicuity

PROBLEM: Most pedestrian fatalities occur at night. Although researchers have long understood that drivers have difficulty seeing pedestrians at night and that reflective clothing can dramatically enhance pedestrian conspicuity, the extent to which pedestrians understand these facts is unclear. This experiment quantified pedestrians' estimates of the ability of an approaching driver to recognize the presence of roadside pedestrians. METHOD: Ten younger and 10 older participants walked in place on the far shoulder of a closed-road circuit and pressed a button when they were confident that the approaching driver could first recognize that a pedestrian was present. RESULTS: Pedestrians overestimated their visibility and dramatically underestimated the benefit of conspicuity treatments. CONCLUSIONS: These results suggest that pedestrians fail to understand the magnitude of the nighttime conspicuity problem and the value of conspicuity treatments. Pedestrians may therefore unknowingly place themselves in danger at night. IMPACT: These results underscore the need to educate pedestrians about the dangers of interacting with traffic at night and about treatments that increase their safety.     

我国工业行业安全生产压力指数构建研究

针对单一事故指标在反映行业或区域安全生产形势方面存在的不足,提出采用"安全生产压力指数"这一指标来综合表征我国各行业整体安全生产形势。以工业行业为例,结合我国现有事故统计指标,综合考虑各行业生产安全事故的相对趋势、事故的严重程度以及行业风险控制水平对安全生产形势的影响,构建了以死亡人数占比指数(DNI)、事故严重度指数(ASI)和整体风险水平指数(TRI)为基础指标的安全生产压力指数(SPI)计算模型。通过对工业行业及其11个重点行业事故基础数据的采集整理,分别测算了工业行业1978-2011年度以及11个重点行业2007-2009年度的SPI指数,分析了SPI指数在安全生产形势表征和安全生产形势预警方面的作用,提出了深化和完善SPI指数应用的建议。     

General and specific measures in organizational behavior research: Considerations,examples, and recommendations for researchers

Deliberation over and relative preference for general or specific (broad or narrow) constructs has long been an important issue in organizational behavior research. In this article, we provide a review of this general issue and some specific recommendations for researchers. We begin by discussing whether the general versus specific issue is an important debate and by discussing other underlying issues (the role of researcher preferences, distinction between reflective and formative indicators, and distinction between constructs and measures of constructs). Building on Chen's (this issue) analysis of core self‐evaluations, we first discuss how the general–specific debate has progressed in core self‐evaluations research. We then discuss three other important areas in which this debate has played out: intelligence, five‐factor model of personality, and job attitudes. Finally, we offer a framework to help guide decisions about whether to utilize general measures, specific measures, or both and conclude by providing recommendations for the use of general and specific measures in organizational behavior research.
