chinese science Bulletin 1989年第17期34卷 1409-1412页

作者：吕健安高恒珊 graduate School of Academia Sinica Beijing

Let S be a propositional modal system and S~* be the quantification of S, then we can prove the algebraic semantic completeness theorem of the kind of Rasiowa-Sikorski for S~* by showing that S has the property (E)given in [1]. But except for a few cases, it is very difficult to show thara system S has the property (E). So for most quantified modal systems,

Objective Accumulated data show that the mechanisms of transcutaneous electrical acupoint stimulation (TEAS)analgesia involve the activation of endogenous opioid antinociceptive systems and theμ-opioid receptors (MORs)in the central nervous system(CNS).Positron emission tomography(PET)is the only real time in vivo method available today to study u-opioid receptor *** this study we investigated the different effects of low and high frequency TEAS on MOR binding potential of the brains in rhesus *** PET with C-carfentanil was performed three times randomly under TEAS of 0 Hz,2 Hz or 100 Hz respectively in each monkey separated by at least 2 *** was administered in the middle 30 min during the 95 min PET *** images were reconstructed in 3D OSEM *** distribution volume of three stages(before,during and after TEAS)were calculated using Logan plot with an online arterial radiocounting as input function and were analyzed using Statistical Parametric Mapping(SPM).Results 2 Hz TEAS evoked an increases in MOR binding potential in multiple pain and sensory processing brain regions including the dorsal cingulated cortex,caudate nucleus,putamen,temporal lobe, somatosensory cortex and amygdale during the TEAS compared with that of 0 Hz *** effect remained after TEAS in genual anterior cingulate cortex and temporal *** increase in MOR binding potential was found during and after the 100 Hz TEAS compared with 0 Hz *** The increases of u-opioid receptor binding potential in multiple pain and sensory processing brain regions may play a role in mediating the effect of low,but not high frequency TEAS.

＜正＞This paper presents a stochastic optimal controller using the variable-period sampling Networked Control Systems （NCSs） model,where it has been assumed that the random network-induced delay only exists between sensor and controller and the time delay occuring at current sampling step is taken as the sampling period between current sampling step and next sampling *** is assumed that the random delay is subjected to a uniform distribution in the interval between 0 and the maximal random *** proposed stochastic optimal controller is shown to produce a closed loop system which exhibits exponentially mean square *** the end,the simulations on an inverted pendulum process and DC motor are studied,which show that the proposed algorithm can produce desired control effect.
