[求助] 请问这里的百分数都表示的是什么呢？

For comprehending the solvation dynamics process, a thorough
understanding of the micellar structure and location of the
probe within the micelle is necessary. The dielectric constant is
an important tool for measuring the polarity of a solvent, which
changes from bulk solvent to micellar solution with the probe
in the palisade layer.72 According to the molecular approach for
the solvation relaxation process, which takes into account the
solvent structures around the probe, it appears to be more
logical to understand the results in micellar media, although it is
more complicated than the homogeneous solution. Inside the
micellar palisade layer, the movement of the water molecules is
much more hindered than the bulk water molecules, hence it is
expected that the solvation process inside the micelle should be
slower than that in the bulk. The water molecules adjacent to
the probe are much more restricted and difficult to rearrange
than the water molecules somewhat away from the probe. So
the slower solvation component arises from the response of the
few restricted water molecules that are adjacent to the probe,
and the collective response of the relatively large number of
water molecules that are not in the vicinity of the probe gives
rise to the faster solvation component.75 From UV−visible
spectra, fluorescence spectra, and also anisotropy values, one
can conclude that the probe molecules reside inside the
palisade layer of the micelles. The average solvation time of C-
343 at 298 K in aqueous solution of 28 mM SB-16 was found to
be 2.02 ns (Table 3), with components 0.64 ns (80%) and 7.57
ns (20%). The process becomes faster in the presence of both
the surfactant (SDS) and the RTIL (EmimOs), and the effect is
more pronounced in the case of SDS. With the addition of 10
mM EmimOs and SDS to 28 mM SB-16 solution, the average
solvation time changes from 2.02 to 1.36 and 1.00 ns,
respectively. The slow component of the solvation time of C-
343 at 298 K in 28 mM SB-16 solution was found to be 7.57 ns
with amplitude of 20%. With addition of 10 mM EmimOs, this
value decreases from 7.57 to 3.23 ns and the amplitude changes
from 20% to 33%, which clearly indicates that the strength of
the hydrogen bonding decreases but the water penetration
increases. On addition of 10 mM SDS to the 28 mM SB-16
solution, the slow component decreases from 7.57 to 1.19 ns
and the amplitude increases from 20% to 76% which suggests
that the strength of hydrogen bonding decreases while the
water penetration increases abnormally. This is a manifestation
of the movement of the probe molecules to the bulk water
phase.

The average solvation time of C-343 at 298 K in aqueous solution of 28 mM SB-16 was found to be 2.02 ns (Table 3), with components 0.64 ns (80%) and 7.57ns (20%).
这里可能是不同组分的溶剂化时间分布，有80%为0.64 ns，20%为7.57ns，平均0.64x80%+7.57x20%=2.02ns.
这些百分比看来是该类组分的丰度（含量百分比）。
The slow component of the solvation time of C-343 at 298 K in 28 mM SB-16 solution was found to be 7.57 ns with amplitude of 20%
慢组分的溶剂化时间 7.57 ns丰度20%
With addition of 10 mM EmimOs, this value decreases from 7.57 to 3.23 ns and the amplitude changes from 20% to 33%,
加EmimOs后该值（溶剂化时间）变为3.23 ns，丰度由20% 变为 33%。
余同。

我就是不太明白这里的百分比是指的什么东西的百分比，麻烦您给看一下吧。谢谢啦
