The paper proposes a new measurement method of angular acceleration for photoelectric servo turntable. Piezoelectric angular acceleration sensor is used to measure angular acceleration directly
Adaptive FIR filter based on LMS algorithm is established on DSP
by which angular acceleration signal can be filtered and corrected errors adaptively
then angular acceleration signals can be measured adaptively. This method avoids measurement errors and calculation noise by computing angular acceleration indirectly
thus improving measurement precision and making measurement results better than traditional methods. The gotten angular acceleration can be sent to servo control mechanism as feed forward control signals to improve control effects of servo turntable significantly. 2011 IEEE.

The
J/Ψ
hadronic
decays
involving
2(π+π-)π°and
2(K+K-)
final
states
are
investigated
by
using
the
sample
of

J/Ψ's
which
were
obtained
from
the
BES
detector
at
BEPC
in
the
first
half
of
1990.
Some
signals
such
as
ω(782)
φ(1020)
f2(1270)
f2'(1525)
θ/f2(1720)
b1(1235)
and
a2(1320)
have
been
found
and
measured
the
mass
width
and
branching
fraction
of
reasonance
states.
The
results
are
agreement
with
the
world
average
values.
The
ratio
of
Br(J/Ψ
→
ω
f2(1270))/Br(J/Ψ→ρ°a2°)
shows
that
doubly

violating
effects
play
a
role
in
the
