1.This paper studied hazardous constituent of percolate from the place that rubbish was buried Percolate sample was pretreated in proper method, major constituent was qualitative identified by GC/MS and AES first Then trace amount of Cu, Zn, Pb, Cr, Cd, Hg, Phenol, p methylphenol, aniline and anthracene in the percolate sample were successfully determined by atomic absorption spectrometry and reversed phase high pecformance liquid chromatography
渗出液样品用适当的方法处理后 ,用气相色谱 -质谱联用方法和原子发射光谱法进行定性分析。 然后用原子吸收分光光度法和反相高效液相色谱法定量测定样品中微量的 Cu、Zn、Pb、Cr、Cd、Hg、苯酚、对甲苯酚、萘、蒽
2.Pre treatment of garbage percolate with anaerobic biological filter tank was tested and studied in the treatment of garbage percolate. The results show that anaerobic biological filter tank not only has very good defoaming and CO2 and H2S desorption functions but also has the function of removing COD and NH3 N in the percolate to some extent.
在垃圾渗滤液处理中,对缺氧生物滤池预处理垃圾渗滤液进行了试验研究,结果表明:缺氧生物滤池不仅具有很好的消泡、脱吸CO2和H2S的作用,而且对渗滤液中的COD和NH3-N具有一定的去除作用。
3.The optimized extraction technology followed as: the five kind of herbs were crashed to coarse powder, add alcohol to distilled water solution and made it became 50% alcohol solution as percolate liquor, percolate speed was 1 ml·kg~(-1)·min~(-1).
羌活、防风等五味的最佳提取工艺为：羌活、防风等五味粗粉(20目)，提取挥发油的提取液加乙醇使含醇量50％，渗漉速度为1ml·kg~(-1)·min~(-1)。
4.The linear range of this method is 0 0 9 to 0 6 mg/L, whereas its detection limit is 5 μg/L No significance discrep ancy between the proposed method and the standard 4-AAP method was observed, whe n it was applied to rubbish percolate analysis The recovery is in the ran ge of 96%~103% This method has the advantage of good selectivity,high sensit ivity and good precision.
方法的线性范围为 0 .0 9～ 0 .6mg/ L,检出限为 5 μg/ L。 用于垃圾渗出液的测定 ,结果与 4-氨基安替吡啉法无显著性差异 ,回收率在 96%～ 10 3 %之间 ,该法具有选择性好、灵敏度高、重现性好的特点
5.Porous pavement, which allows water to percolate through instead of run off, is being tried in parking lots [see illustration, far right].
这种设计在欧洲相当普遍，在美国的透水性路面也逐渐风行起来，这种路面可让水份渗透，而不是让水流走，目前已有许多停车场开始试用（见最右图）。
6.To wash or percolate the soluble matter from.
沥滤从……中洗去或滤去可溶性物质
