v/v你可以写成volume to volume w/v ：weight-volume percentage，percent weight per volume，Weight-in-volume etc EXPLANTATION:v/v2% v/v means that the volume of the substance is 2% of the total volume of the solution or mixturew/van abbreviation for "weight by volume," a slightly confusing phrase used in chemistry and pharmacology to describe the concentration of a substance in a mixture or solution. The weight by volume is the mass (in grams) of the substance dissolved in or mixed with 100 milliliters of solution or mixture. For example, the concentration of fluoride in toothpaste is usually about 0.15% w/v, meaning that there is 0.15 gram of fluoride per 100 milliliters of toothpaste. Thus 1% w/v is equal to 1 gram per deciliter (g/dL) or 10 grams per liter (g/L). 谢谢 受教了。 SSR wrote:不好意思，刚才表述不清楚 这个意思我明白 【求助】关于elsevier的offp【共享】关于投稿时候选择【求助】EHJ100天了【求助】First name和last nam【求助】欲投BBRC但图片大于【求助】毕业的论文是必须【求助】请教＂awaiting rev【转贴】审稿体会：细节决【求助】如何获得清晰得【求助】editor怎么总在换呀【求助】一篇SCI文章可以有【求助】投稿JBJS(Br)图片要【求助】急！
