热导池

STUDY OF THE QUANTITATIVE METHOD IN KATHAROMETER GAS CHROMATOGRAPHY BY USING AIR AS STANDARD

以空气作标准的热导池气相色谱定量方法的研究

The effect of the density of MeO (volume fraction,%) on the contact area of the molten pool and fusion force was discussed in details.

结果表明：与第二相MeO的密度、热导率及体积分数等物性参数对熔池接触面积的影响相比，电弧输入能量的影响才是最主要的。

Fully automatic sample feeding of up to 60 samples into a steel combustion tube, high temperature digestion at 900°-1000°C.Oxygen saving, sensor controlled gas supply.Detection of nitrogen after reduction on tungsten by means of a special low-noise thermoconductivity detector.Carbon determination as CO2 and hydrogen determination as H2O with "purge and trap" technique and TCD detection.

通过装有60个样品的全自动进样器，将样品送入不锈钢的燃烧管内，样品在900° C －1000° C 的高温并通过由传感器控制的加氧装置加入纯氧进行氧化，燃烧气体中的氧化氮被钨还原成氮并通过特殊的低噪音的热导池被检测，其后通过分离装置将 CO2和 H2O 进行分离并通过 TCD 检测得出碳和氢的含量。

I didn't watch TV last night, because it .

昨晚我没有看电视，因为电视机坏了。

Since this year, in a lot of villages of Beijing, TV of elevator liquid crystal was removed.

今年以来，在北京的很多小区里，电梯液晶电视被撤了下来。
