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。
