Abstract: A method for synchronizing management of a plurality of domain names in a Domain Name System (DNS), which method comprises: receiving a synchronization request for synchronizing a first object related to a first renewal date of a first domain name with a second object related to a second renewal date of a second domain name, the synchronization request including an explicit identifier only of the first domain name but not of the second domain name; locate both the first object and the second object in a domain name database; determining a renewal date which is earlier than at least one of the first renewal date and the second renewal date; and synchronizing as a backwards synchronization operation the first object and the second object to both have said renewal date, such that both the first domain name and the second domain name are configured to expire on said renewal date.

Abstract: An equipment and method for forecasting tunnel water inrush using a magnetic resonance differential, where a computer is connected to a transmitting bridge circuit through a high voltage power supply, to a control unit, a first and second signal modulating circuits and a multi-channel collecting circuit; the control unit is connected to a transmitting driver circuit, a first and second protection switches, and the transmitting bridge circuit through the transmitting driver circuit; two ends of a transceiving multi-turn coil are connected to the multi-channel collecting circuit through the first and second protection switches; two ends of a receiving multi-turn coil are connected to the multi-channel collecting circuit through the second protection switch and the second signal modulating circuit; one end of the transceiving multi-turn coil is connected to the transmitting bridge circuit, and the other end is connected to the transmitting bridge circuit through a resonant capacitor.
