7.Methods:Three opioid peptides (β EP,L EK,DynA 1 13 ) at four concentrations(10 -15 ,10-12 ,10 -9 ,10 -6 mol /L) were put in to islet culture of rats.
8.Using the blackbody of 500K and He?Ne laser, the typical results of the two kinds of detectors are as follows: the noise equivalent power?NEP(500,10,1) values are 3.6×10??-12?and 4.1×10??-12?W/Hz??1/2?,normalized detectivity ?D??? 1.6×10??10?and 1.2×10??10?cmHz??1/2?/W;
