在研雷诺数范围（66－1060）于这里加以研究的过程中，在0号处的7uid7ow应在层流7ow状况。在雷诺数为66时（这相当于低雷诺数），偏析指数大约为0.7，表明相当差的微流体混合环境。Further

the

the

substantially.
For
example,
Xs

0:25;
0:17;
0:13,
and
0.09
for
ReEM=159;
265;

and

respectively.
进一步提高雷诺数使偏析指数大大降低。例如，对于ReEM＝159；265；477和663来说，Xs分别等于0：25；0：17；0：13和0.09。Notably,
at

7ow
in
an
empty

For
example,
at
ReEM

060,
the
segregation
index
becomes
as
low
as
0.04.
Such

observation
may
be
attributed
to
the
interference
of
the
feeding

to
the
7owing
7uid
that
generates

which
inces
uncertainty

Next
consider
the

At

the

Xs
=0:48;
0:47;
0:52

0.57
at

1–4.
例如在ReEM＝1，060时，偏析指数变成低达0.04.这样一个观察结果可归因于进料嘴对7owing7uid的干扰，它产生了局部的湍流，这在Xs测量中引入了不确定性。接下来考虑静态混合器的情况。在ReEM＝66时，相应的Xs变的低于空管的值，在1号到4号位置Xs＝0：48；0：47；0：53和0.57。The

静态混合器的存在因此会明显提高地雷诺数层流状况下的微流体混合效率。Notably,

the

However,

could

that
(1)
the

(2)
the

特别是，在0位置处CH+与1号到4号位置处的不同，
由于采用静态混合器对微流体混合作用的提高不能直接加以比较。可是，人们仍可以注意到，1）静态混合器已明显改善了微流体混合的环境；2）用于Brst两种元素的微流体混合环境优于混合器后续的元素，作为证据，前两种元素的Xs较低。At

the

0:04
and
0.03
at

265;
477;
663
and
1,060,
respectively.
Restated,
at
a
Reynolds
number
exceeding
approximately
200
the

0.1在较高雷诺数时，Xs随之下降。例如在2号位置，在ReEM＝159；265；477；663和1，060时分别为Xs＝0：17；0：08；0：05；0：04和0.03。复述一下，在超过大约200的雷诺数时，偏析指数可以达到小于0.1的低水平。
