Basisd on the controlled stocking rates, comparable repeated experiment was conducted to understand the stability of grazing ecosystem in vegetation, soil and livestock, considered the year as the principal component to evaluate the effect and mechanism of annual precipitation on grazing ecosystem characteristics, using the coefficient of variation in terms of ANPP and decrease and increase of functional groups to reveal the ecosystem stability and ecological compensatory effect in grazing ecosystem. The result not only richens the study contents of ecosystem stability, but also provides a guide for adaptive rangeland management plans, which are promoted the ecological and economic sustainable development.

A competitive ELISA kit for detect ENR was developed with ENR mAb and its traits were tested.Two hybridoma lines were filtered and the best one was 4G1-B3,which secreted ENR mAb with indirect ELISA titers of 1∶1.024×10~6 in ascites.Isotype of the two mAb was IgG_1.ENR mAb had a high affinity constant with 9×10~(10)L/mol.The ENR-Kit had the linear detection range of 0.05～101.6μg/L,the sensitivity of 0.05 μg/L and a good sensitivity with an IC_(50) of 1.1μg/L to ENR,cross-reactivity to other compounds less than 0.01%.The average recoveres of ENR spiked in chicken,liver,fish and milk were 81.5%,87.6%,84.3% and 95% respectively.The coefficient variation was below 10%.

In a O〓-Ar mixture, the dynamic process of vibration-dissociation coupling behind a primary shock front is studied. The variation of many of the physical quantities with time are calculated out, such as the vibrational energy level distribution, the vibrational energy, the vibrational relaxation time, the dissociation incubation time, the dissociation product concentration, the dissociation rate and the dissociation rate coefficient.
