promotion video（有人说和我们所说的mv是一回事，其实不然，看名字就知道啦，是宣传推广用的video，大家也应该注意到了pv都是在单曲推出前10天左右就在电视上有播了，就是为了宣传即将到来的新单曲，而我们所说的mv，都是和歌曲同步推出，或者晚一点吧~）
pv（pageview），即页面浏览量，或点击量；通常是衡量一个网络新闻频道或网站甚至一条网络新闻的主要指标；当然，有时还会同时考察另外一个指标，即uv（unique visitor），指访问某个站点或点击某条新闻的不同ip地址的人数。
渗透汽化（perwaporation,简称pv），液体混合物的分离技术，它是在液体混合物中组分蒸汽压差推动下，利用组分通过膜的溶解与扩散速率的不同来实现分离的过程。根据膜的功能，pv膜可分为亲水性膜和亲醇性膜两类，亲水性膜优先透过水，适宜分离含水量低的醇/水混合物；亲醇性膜优先透过醇类，适宜分离含醇量低的醇/水溶液。
