体内研究 |
Goldfishes which are treated with salt have significantly lower mucus weights at 25h.Goldfishes treated with Polyvinylpyrrolidone (PVP) have significantly higher mucus weights at 25h.Koi treated with salt and Polyvinylpyrrolidone (PVP) has significantly lower mucus weight at 1 and 25h.Control koi has significantly higher mucus at 25h.At the end of 2 weeks,it is determined that the three koi treated with salt and Polyvinylpyrrolidone(PVP) remain healthy and show a higher degree of healing than other treatment koi and the control group. |

Each fish within a tank serves as a replicate.Treatments are designated as Polyvinylpyrrolidone (at a dose of 10mL/10 gallon) and saline/salt at 3g/L.A control group that does not receive any chemical is also included in the study.All fishes from each treatment group are sampled at 0 min,15 min,1h,4h and 25h.At each time interval,all fishes from each treatment group are anaesthetized using buffered tricaine methanesulfonate,weighed,and slime is scraped from one 1 cm2 area over the epaxial musculature using a preweighed plastic coverslip. |

本计算器可帮助您计算出特定溶液中溶质的质量、溶液浓度和体积之间的关系，公式为：
质量 (g) = 浓度 (mol/L) x 体积 (L) x 分子量 (g/mol)
摩尔浓度计算公式
用本工具协助配置特定浓度的溶液，使用的计算公式为：
开始浓度 x 开始体积 = 最终浓度 x 最终体积
稀释公式
稀释公式一般简略地表示为：C1V1 = C2V2 ( 输入 输出 )
