In view of interlayer and areal problem after multi cycle of huff and puff, a new high temperature temporary blocking agent has been developed through laboratory experiment and field test.
At the maintaining stage, vorticity and enstrophy of barotropic and baroclinic reach maximum when blocking has built and stayed at the blockingfield.

In the field research, positive rate of circulating antigens from middle epidemic area(34.52%, 87/252)was markedly higher than that from transmit blocking area(9.72%, 49/504).
