  absorbing column
Also we present new EXOSAT results, and discuss their implication for determination of the X-ray spectrum - spectral index and absorbing column.
      
Inclusion of additional low energy data from the EXOSAT telescopes allows the modelling of the absorbing column to be improved and reveals a second, separate, soft X-ray spectral component.
      
The PSD spectrum of the SNR is fitted with a Raymond and Smith line-emission model: the best fit temperature is found to be 1.7×l06 K and the absorbing column is less than 2×1021 cm-2.
      
These dips are accompanied by strong variations in the spectral hardness consistent with large changes in the absorbing column density.
      
The medium energy spectra during dips with respect to the non dip spectrum can be explained by just enhanced cold gas absorption of an additional absorbing column of 2 1022 cm-2.

This article describes a new pressure enriching apparatus for organomercury in river water. Since the absorbing column is small and easy to be sent by post or carried by people, the difficulty of transporting a large quantity of water sample is avoided and problems of loss and transform of different species of mercury are eliminated. Therefor, the result is more representative and realistic. After the enrichment for the second time with a sulfhydryl cotton column in lab, a relative sensitivity of...

This article describes a new pressure enriching apparatus for organomercury in river water. Since the absorbing column is small and easy to be sent by post or carried by people, the difficulty of transporting a large quantity of water sample is avoided and problems of loss and transform of different species of mercury are eliminated. Therefor, the result is more representative and realistic. After the enrichment for the second time with a sulfhydryl cotton column in lab, a relative sensitivity of 0.03ppt is reached. The technique can be used to determine the back-ground level of organomercury in natural water.

本文介绍一种自行设计的加压吸附富集装置,其吸附柱体积小,便于携带或邮寄,适于全国各地区现场富集含有机汞的水样,避免了运输大量水样的困难,从根本上消除了贮存过程中的损失和化合物形态互相转化等问题。使分析结果更富有代表性和真实性。在实验室内结合二次巯基棉柱富集,相对灵敏度可达0.03ppt,可以应用于天然水样中有机汞背景值的测定。

The effect of the length and diameter of the absorbing column and the sepa-rating column packed with cation exchanger, the flow rate of the eluate, the load-ing of the samples (Eu, Sm, and Nd) and the pH values of the eluate of α-HIBAon the separation of Eu, Sm, Pm and Nd in the spent fuel are studied usingHPLC. A procedure for the separation using the best separation conditions is re-commended, The blank of Nd is (2.5±0.5)×10~(-8)g in the whole procedure whichstarts from dissolving fuel sample and ends in preparing Nd sample for mass sp-ectrometric measurement. The procedure is practical and gives good analytical re-sults as being verified by the mass spectrometric measurements of Nd and Sm andthe γ-spectrometry of ~(147)Pm and Eu.

The Iow recovery rate of phenols is maily due to low concentration of phenols in the fractions of carbolic oil and naphthalene oil, more emulsified preducts arising from scrubbing of the carbolic oil fraction with alkali and extraction of the phenolic effluents in process of dephenolization,some volatile phenols going into air during decomplsition of the phenolate,much of the xylenol and the higher phenols remsined in the phenolic sludge when the crude phenol is refined.To increase the recovery rate of phenols...

The Iow recovery rate of phenols is maily due to low concentration of phenols in the fractions of carbolic oil and naphthalene oil, more emulsified preducts arising from scrubbing of the carbolic oil fraction with alkali and extraction of the phenolic effluents in process of dephenolization,some volatile phenols going into air during decomplsition of the phenolate,much of the xylenol and the higher phenols remsined in the phenolic sludge when the crude phenol is refined.To increase the recovery rate of phenols i n the coaltar processing plant,it is necessary to improve the technological system including good operations and strictiy control the qualities of phenolic effluents feeding into extraction column and flushing ammonia liquor for batteries of coke oven. Meanwhile,it's important to set up some devices such as absorbing column for acid vapour decoposed from phenolate, distillation unit for crude phenol sludge.

酚产品收率低的主要原因是:焦油加工车间酚油和素油的酚集中度低、馏分碱洗脱酚和废水萃取脱酚过程中乳化物多;酚盐分解时一些挥发酚进入大气;粗酚精制后酚渣中遗留的二甲酚和高级酚大多。要提高焦化企业的酚收率,除改进工艺制度及认真操作外,还要严格控制入萃取塔的废水质量及焦炉循环氨水质量。同时,应尽量完善设施,诸如设立酚盐分解酸汽吸收塔、酚渣蒸馏等装置。
