2.To purify(a gas) by passing through or over a liquid, as to remove soluble matter.
3.In the case of an N_2/O_2 mixed atmosphere,the FPD density and the oxygen precipitation density decrease with the increase of O_2 content.
4.Because of the addition of filling agent, some characteristics of Polyterafluoethylene are greatly improved, especially on abrasion resistance, heat conductivity, contravariance and self lubrication, which are obviously better than pure Polytetrafluoethylene Products.
5.It really looks different! It is a strange color that's not quite yellow and not quite orange to look at.
8.The adsorption isotherm curves of nitrogen,methane,carbon monoxide and carbon dioxide on adsorbents CNA 133 and CNA 229 have been experimentally determined at different temperature in a volume adsorption apparatus.
10.The anti - mutation research of Glycyrrhiza Vralensis Fiseh have been made, with the micronucleus in peripheral blood lymphocyte of human body as the index. The result is the eame as that of the research we made with the sister chromatid Exchange (SCE)in C57 pure mice marrowy cell as the index. Glycyrrhiza Vralensis Fisch possesses the function of arti - mutation.
