[求助] 我翻译的不够准确,请麻烦专业人士帮忙翻译一下

Previously we have investigated the structure of adsorbed
CnE4 layers at the EAN−air interface using neutron reflectivity
and vibrational sum frequency spectroscopy as function of alkyl
chain length (n = 12, 14, 16), concentration, and temperature.
The tetra(ethylene glycol) head group layer was found to be thin, compact (incorporating only ∼30% EAN by volume), and
disordered; there is no preferential orientation of the
ethylene glycol groups. Similarly, the alkyl tail groups have a
significant number of gauche defects indicating a high degree of
conformational disorder. The thickness of this nonpolar layer is
much less than the fully extended chain length, but it does
increase with alkyl chain length. Lowering the concentration of
C12E4 from 1 to 0.1 wt % decreased the surface excess, and the
head group layer became thinner and less solvated, but C14E4
and C16E4 adsorbed layers were unaffected over the same
concentration range, indicating that their cmc’s are lower than
0.1 wt %.

以前我们研究过CnE4吸附层在EAN-空气界面处的结构,。。。。。
The tetra(ethylene glycol) head group layer was found to be thin, compact (incorporating only ∼30% EAN by volume), and disordered; there is no preferential orientation of the ethylene glycol groups.
乙二醇头部组层是薄的、紧凑的(按体积加入30% EAN )和无序的;并没有发现乙二醇组存在择优定向。

Similarly, the alkyl tail groups have a significant number of gauche defects indicating a high degree of conformational disorder.
同样,烷基尾组存在大量可以显示处于高水平构象无序的低级缺陷。

The thickness of this nonpolar layer is much less than the fully extended chain length, but it does increase with alkyl chain length.
这个非极性层的厚度远小于完全伸展链长度,但它确实随烷基链长度而增加。
Lowering the concentration of C12E4 from 1 to 0.1 wt % decreased the surface excess, and the head group layer became thinner and less solvated, but C14E4 and C16E4 adsorbed layers were unaffected over the same concentration range, indicating that their cmc’s are lower than 0.1 wt %.
当C12E4的浓度从1%降到0.1%(wt为重量单位)时,表面过剩减少、头组层变得更薄且溶剂化降低,但是在相同的浓度范围,C14E4和C16E4吸附层 不受影响,说明它们的cmc(临界胶束浓度)可能低于0.1%。
