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  2.5  *  10~6  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  OZI  violating  effects  play  a  role  in  the  J/Ψ    ω  f2(1270)  f2(1270)    π+π-  are  given  in  the  first  time:  x  =  0.99  ±  0.29  Y  =  -0.24  ±  0.17  Z1  =  0.90  ±  0.57  Z2  =  0.56  ±  0.22.
