提出了应用流动注射梯度稀释法与原子吸收光度法相结合，样品不经稀释便可同时测定酸雨中不同浓度的钙。方法快速简便。
Flow injection serial dilution techniques was combined with atomic absorption spectrometry (AAS) techniques to determine Ca in acid rain without samples' dilution. This method was fast and simple.
采用平皿菌落计数法、培养基稀释法、低速离心结合培养基稀释法进行方法验证。
Plate count method, method dilution method, low speed centrifugalization and dilution medium were taken the verification of methodology.
污水色度的测定一般采用稀释倍数法，该方法在用人眼判定稀释后的水样是否接近无色时容易引起误差。
The method for determine sewage's chroma is method of dilution multiple. It's easy to bring in error when using eyes to determine the diluted sample is whether achromatism or not.
