求助BET分析
|
|
大家好 我最近做了一個(gè)硅球的BET分析，測(cè)了一下比表面積和孔徑，我雖然拿到了數(shù)據(jù)，但是不會(huì)分析，硅球高手指點(diǎn)。很希望這里的高手能幫助我，不勝感激。能不能有人教教我呢，數(shù)據(jù)我也不會(huì)往這個(gè)上面上傳。 |

relative pressure absolute pressure quantity adsorbed elapsed time ssaturation 其實(shí)就是想問(wèn)問(wèn)這五組數(shù)據(jù)在做吸附和解吸附圖形的時(shí)候，是不是能用得到？這些數(shù)據(jù)時(shí)用來(lái)干什么的。 為什么吸附和解吸附的數(shù)據(jù)給了兩組，作圖之后重合性還比較好。 為什么有 relative pressure quantity adsorbed 1/[Q(p°/p- 1)] 這三組數(shù)據(jù)？ 以及Relative Pressure (p/p°) 1/[Q(p°/p - 1)]這兩組數(shù)據(jù) 1/[Q(p°/p - 1的含義是什么？ |
