爱华网概念近来快速发展之光学材料COP，最有机会取代TAC保护膜之角色，因其光学特性不输TAC，而机械性、耐温性及耐候性远超过TAC，目前问题在于价格约为TAC三倍而未能普及，不过值得期待 COP(Coefficient Of Performance),即能量与热量之间的转换比率，简称制热能效比。 COP也称之为顾客导向过程
cop_cop -示例
单位1的能量，转换为单位0.5的热量，即COP为0.5。
cop_cop -定义
COP值在ARI标准中，关于冬夏季循环效率提出了以下定义：
在冬季供热时，制热量（W）与输入功率（W）的比率定义为热泵的循环性能系数COP（coefficient of performance，W/W）；
在夏季制冷时，制冷量（W或Btu/h）与输入功率（W）的比率定义为热泵的能效比EER（energy efficiency ratio，W/W 或Btu/W.h）
为不引起歧义，我们将冬季热泵循环性能系数和夏季热泵的能效比表达形式均采用COP（能效比）表示。
cop_cop -计算公式
其计算公式为 ：ε=Q/N=Q/N・ηs=ε・η 。
Q:制冷系统需要的制冷量（制热量）
N:制冷压缩机的理论功率
N:轴功率
ε:是理论制冷系数（制热系数）
η:是总效率（绝热效率）
COP值(制冷效率)实际就是热泵系统所能实现的制冷量（制热量）和输入功率的比值，在相同的工况下，其比值越大说明这个热泵系统的效率越高越节能；因此在作制冷系统COP值比较之前，首先要确定各个热泵系统是否在相同的工况之下，然后再进行计算比较。
cop_cop -影响因素
影响机组的COP的因素有以下几点：a、压缩机的性能系数b、热泵机组的系统匹配性：（所谓系统匹配是指：压缩机、冷凝器、蒸发器、节流机构和自控系统的匹配性能。）
COP：Common on-chip processor 标准片上处理器
cop_cop -俚语
学英语的人都知道police是警察的意思，可在美国人们说警察普遍用cop这个词。对英文有些研究的人会说，cop是police的俚语，不是警察的正式用语。那可真是太学究了，因为现在连美国总统、美国国会说警察也常常用cop这个词。其实cop和police或“原指警察制服上的铜扣子，慢慢人们就以扣子代警察了”都没什么关系，但是cop可以说是从copper而来的。根据下面的英文，我们可以看到cop是1700左右进入英语词汇（原本属于法语中的caper及后来的拉丁语capere，其实是今天capture的意思），是“抓捕、抓获”的意思。1846年，有报刊在cop后面加上了“er”的后缀，表示“抓捕或逮捕犯罪的人”。在1859年，cop作为copper的缩写开始流行起来。
