质充量压缩着火(
HCCI
)燃烧,作为一种能有效实现高效低
污染的燃烧方式,能够
使发动机同时保持较高的燃油经济性和动力性能,而且能有效降低
发动机的
NO
x
和碳烟排
放。此外
HCCI
燃烧的一个显著特点是燃料的着火
时刻和燃烧过程主要受化学动力学控制,
基于这个特点,
发动机
结构参数和工况的改变将显著地影响着
HCCI
发动机的着火和
燃烧过
程。本文以新型发动机代用燃料二甲醚(
DME
)为例,对
HCCI
发动机燃用
DME
的着火和
燃烧过程进行了研究。
研究采用由美国

采用该方法研究了压缩比、燃空当量比、进气充量加热、发

对

ABSTRACT
Lepidopteron wing scales with
their periodic dielectric structures
producing
glaring
iridescent
colors attract great attention in bio-photonic
devices design and fabrication
during
the past decade. One inevitable drawback of these
bio-templates is the lack in
flexibility
limited
by
the
wing
scales?
inborn
inner
microstructure.
We
des
ign
two
novel
routes
to
control
and
modify
the
original
structure
of
Chrysiridia
rhipheus
(sunset
moth)
wing
scales
and
thus
their
optical
properties,
using
a
kind
of
biocompatible
environment
sensitive
interpenetrating
polymer
network
(IPN)
chitosan/PV
A.
The
immobilized wing scales? visible reflectance is
responsive to both
the
electric
field
and
the
pH
condition,
owing
to
their
inner
microstructure
change
induced
by
the
IPN
volume
change
in
the
swell/deswell
process
driven
by
electric
field
and
pH
condition.
Using
electric
field
as
the
driving
force,
we
obtain
a
total
~150nm
visible
reflectance
shift
within
several
minutes,
which
can
be
used
as
an
optical
switch or electric field sensor; in pH driving
system, we obtain a total ~260nm
visible
reflectance
sh
ift,
and
prominent
sensitivity
of
moth
wing
scale
indicator?s
optical property in week basic
condition (pH=8-10) promises an in vivo bio-
sensing
pH monitor that can be used in
general bio-medical and bio-controlled
applications.
Our multi-responsive
optical sensors for E-field and pH condition
broaden the natural
species?
pool
for
functional
structure
selection,
and
provide
designable
and
controllable bio-
inspired material solutions according to specific
practical demands.
