The authors define the orders n cohomology groups and a binary function φ(·) of 3-Lie algebraA.Using the function,the authors define the Casimir operator of a representation.And obtain the main result that the orders two cohomology group H2 (A,V) of an non-degenerate 3-Lie algebra A is zero.

In order to evaluate the efficacy of rapid whole-blood agglutination assay(RWBA) established in our laboratory,we tested 534 samples of whole-blood for HBsAg detection from different populatons in Hebei Province of China,and obtained satisfactory results.We detected HBsAg with whold-blood samples from different populations by RWBA,and compared with the results tested by commercial ELISA kit.The parallelled 369 samples from different populations were detected by both RWBA and commercial ELISA kit.Among them,there were 62 clinical patients with hepatitis B,180 cases of blood donors and 127 cases normal population.The total coincident index is 96.7%,the sensibility was 90.9%,and the specificity was 98.7%.The positive rate of population with clinical hepatitis,blood donors,and common population was 52.6%,4.3% and 8.9% respectively.The results indicated that RWBA was not only simpler and faster,need no special instruments,but also had higher sensiblity and specificity.It can be widely used in grass-roots health units and bedsides diagnosis for HBsAg detection.

Two photons fluorescence excitation spectrum in the range of 420～472 nm of NO is obtained.The spectrum is attributed to A2∑(v′=0.1)←X2∏(v″=0)Transition.The value for force constant of k=2.32×103 N/m is gotten.The fluorescence decay spectrum of A2∑(v′=0)→X2∏(v″=0,1…)at different pressure are measured.The value for the spontaneous radiative lifetime of A2∑(v=0) is 195 ns.
