摘要： The invention relates to a method of forwarding multicast message in network communication. In the method: first, establish forwarding match condition at the ingress interface of the network device required to forward multicast message, the forwarding match condition specifies forwarding rule for the multicast message; then, compare the multicast message to be forwarded to network device through the interface with the forwarding match condition, and forward the multicast message according to the comparing result. The invention can configure the sending mode of messages according to requirement and can effectively avoid risks in security that may be caused by the broadcast mode for the multicast messages in the link layer as well as efficiency loss caused by receiving a great deal of invalid multicast messages, and the configuration is simple, and more convenient use and management is realized. In the present invention, forwarding multicast message according to an established multicast message forwarding rule greatly reduces the number of various multicast protocol messages generated in the multicast network and saves bandwidth resource of network.

摘要： In a temperature control method for magnetic field components of a permanent magnet arrangement of a magnetic resonance system, temperature stability of the magnetic field components is achieved by maintaining the temperature of the two sides of the magnetic field components constant, with a difference being maintained between the temperatures of the two sides of the magnetic field components so that a temperature gradient is formed within the magnetic field components. Once the temperature gradient is formed, dynamic temperature stability is established within the magnetic field component. When this dynamic temperature stability is broken by thermal disturbance, the temperature gradient allows the thermal disturbance to be quickly transmitted to the lower magnetic yoke and is further transmitted to the outside through the base of the magnetic resonance system so that the thermal disturbance is smoothed and dynamic temperature stability is reestablished.

摘要： For magnetic resonance imaging (MRI), a dynamic frequency drift correction method for binomial water excitation method includes collecting the reference one-dimensional navigation signal by an MRI device; acquiring one current one-dimensional navigation signal after scanning N images, wherein N is a positive integer; calculating the frequency drift according to the reference one-dimensional navigation signal and the current one-dimensional navigation signal; calculating and setting the initial phase of the next radio frequency signal by the MRI device according to the frequency drift. The method provides real-time calculation of the main magnetic field frequency drift according to the one-dimensional navigation signal during the scanning period and corrects the phase of the radio frequency signal to ensure that the direction of the gradient field is always perpendicular to the plane formed by the spinning of fat protons, so there is only water signal remaining after excitation so that water images can be obtained.
