Abstract: This invention provides a NMR multi-dimensional method for measuring coupling constants within several coupling networks. At first, a 90° hard pulse was performed to flip the magnetization from the Z axis to the XY plane. After t1/2, a selective 180° pulse is implemented with a simultaneous Z-direction gradient, thus reversing different protons at different slices. Then the PSYCHE element is implemented. After another t1/2, the gradient G1 and Gp are implemented. At last, the EPSI readout is used to simultaneously record both the chemical-shift and the spatial information. As a result, from different specific slices, we can extract the scalar couplings between the proton reversed at this slice and other protons. These couplings lead to splittings in the indirect dimension, from which relevant coupling constants can be measured.

Abstract: The present application provides a packet sending method and a network device. The packet sending method includes: receiving, by a network device, a first data packet; and if a MAC entry matching a destination MAC address of the first data packet is not found in a media access control MAC address table of the network device, sending, by the network device, the first data packet according to a forwarding behavior in a MAC default entry of the MAC address table. When the MAC entry matching the destination MAC address of the first data packet is not found, the network device does not need to flood the first data packet on all interfaces, but directly sends the first data packet according to the MAC default entry in the own MAC address table, thereby reducing a need for MAC address capacity in the network device, and not increasing unnecessary network traffic.
