Flame retardants are chemicals, which are added to combustible materials to render them more resistant to ignition. They are designed to abate the risk of a fire in case of contact with small heat sources, such as cigarette, candle, or an electrical fault. If the flame retarded material or nearby material is ignited, the flame retardant may retard the combustion and often prevent the fire from spreading to the nearby environment.  There are a wide range of different chemicals, which are used as flame retardants in combinations with polymers. Fire retardant products are necessary, because the materials and products, which are to be rendered fire proof, are very different in nature and composition. The plastics and polymers are needed to be matched to the appropriate flame retardants, in order to retain the key material functionalities. Flame retardants are necessary to ensure the fire safety of a wide range of materials, including plastics, foam and fiber insulation materials, foams in furniture, mattresses, wood products, and natural and man-made textiles.

50 年金银比价复盘：因为1944-1970 年间布雷顿森林体系依然存在，因此黄金和美元的比价基本保持稳定，在白银价格逐步上涨的背景下，金银比逐步走低。1971 年以前金银价格更多受到政府政策行为的干预，因此对于金银比的研究将主要从1971 年以后开始。如果将金银比连续的上涨和下跌阶段作为一个周期，我们可以分时间周期来研究金银比。
