摘要： A method of accessing in an equipment of a communication network is proposed in the invention. The method comprises the steps of: receiving a message 2 from a base station, the message 2 being used for an assignment of resource to transmit a message 3, the assigned resource corresponding to N HARQ RTTs, where 1≦N≦8; and transmitting the message 3 only in part of the N HARQ RTTs. With the scheme of the invention, a MTC device selectively transmits the Msg3 in one/some HARQ RTT and maintains silence in another one/some HARQ RTT, thus the possibility of the occurrence of access collision with other UEs may be backed off, such that other UEs, particularly human-to-human UEs, may transmit the Msg3 normally. And the possibility of the occurrence of collision is reduced from the viewpoint of the user equipments in a network, reducing entirely the possibility of an access delay and access failure.

摘要： Embodiments of the present invention provide a machine-type communication method and system. Operation capabilities of a machine are determined through a negotiation between the machine and a network (101); and the machine communicates with the network based on the determined operation capabilities (102). By adopting a negotiation mechanism, costs of a machine-type communication are reduced. Embodiments of the present invention further provide a cell search method and device. Transmission parameters for a cell are pre-configured for a device fixed in the cell; the device directly matches the cell using the pre-configured transmission parameters; and the device directly receives data in the case of a successful match. By adopting a machnism of pre-configuring transmission parameters, a cell search process is simplified, and utilization of resources is improved.

摘要： A heat pipe based passive residual heat removal system for a spent fuel pool (3). Partitions (6) are arranged around an inside of the spent fuel pool. Evaporation-end heat pipes (4) are arranged between the outside of the partitions and an inner wail of the pool. The evaporation-end heat pipes have outlets that extend beyond the pool and are connected to an Inlet of an ascending pipe (10), and have inlets connected to an outlet of a descending pipe (5). Condensation-end heat pipes (7) have inlets connected to an outlet of the ascending pipe, and have outlets connected to an inlet of the descending pipe. The heat pipes cool the spent fuel pool. A heat exchange by phase change of working medium in the heat pipe leads to heat exchange of low temperature difference and high efficiency, relying on density difference for natural circulation drive.
