O2 and pH were measured in the river and floodplain water with a YSI 51B and an ORION 250A meter,respectively. Inorg-N and o-P were measured in the river and the floodplain marsh water, and in the interstitial water of the marsh sediment. River and marsh waters were sampled by triplicate and results are given as the mean of the three values. Samples were in situfiltered through Whatman GFC filters. Nutrient concentrations in pore water were assessed by means of a multiple dialysis chamber (‘peeper’, Hesslein, 1976).This consisted of a Plexiglass block (2X15X45 cm)in which small chambers were machined at a resolution of 1 cm, and covered with a biologically inert polysulphone membrane (Gelman DM-200, 0.2 m pore size) protected by a Plexiglass sheet with apertures matching the chambers. The chambers were filled with deionized water in the laboratory and inserted into the marsh sediments. After an equilibration period of 1–2 weeks, the ‘peepers’ we
对于你这个测定方法我不是很了解，试着翻译了一下，楼主看着做个参考吧，呵呵。
采样和分析程序
河水和漫滩水的氧气和pH值分别用YSI 51B和ORION 250A meter法进行测定。无机氮和有机磷根据河水、漫滩沼泽水和沼泽沉积物毛细水测定。河水和沼泽水分为三份测定并取中间值。样品通过Whatman GFC过滤器过滤。沼泽沉积物毛细水中的氮含量由multiple dialysis chamber方法测定(‘peeper’, Hesslein, 1976)。这个仪器由一组规格为1厘米的树脂玻璃皿组成(2*15*45cm),由无菌的聚砜膜覆盖（Gelman DM-200，孔径为0.2微米），膜则由和皿相配的树脂玻璃保护着。皿中注满实验室的去离子水，插入与之相配的沼泽沉积物中。经过一至两周的平衡时间，取出插入的皿并对其中的东西进行分析。有机磷（钼酸盐-维生素C）和硝酸根、亚硝酸根之和（镉还原后重氮化）由Strickland & Parsons (1972)方法测定。NH4C由靛蓝法测定(Mackereth et al., 1978）。
