The invention relates to an anti-fatigue cold mixed epoxy resin material, preparation method and application thereof, comprising component A and component B with mass ratio of 1:1-10:1, component A comprising fluid epoxy resin, active toughener, active diluents, coupling agent and defoamer; component B is any one of or a mixture of two or more than two of alicyclic amine or amino terminated polyether, cyanoethylamine, phenolic modified amine or hydroxyalkyl modified amine. Introduced epoxy terminated organosilicon block polyurethane prepolymer breaks the limitation that elongation at fracture of epoxy resin system based on 'sea-island structure' is difficult to break through 100%. The invention is suitable for bridge deck pavement of long-span cable bearing bridge, waterproof bonding material or used for airport pavement, municipal viaduct, ramp and other occasions with high requirements for fatigue resistance of pavement material.

A circuit board testing device electrically coupled to a measurement gauge tests a circuit board. The circuit board testing device includes a processor configured to configure measurement parameters of the measurement gauge, configure measurement rules for testing the circuit board, confirm a circuit of the circuit board to be tested according to the record of test data, control the measurement gauge to test the circuit of the circuit board to be tested when the measurement gauge is electrically coupled to the circuit of the circuit board to be tested, receive measurement data returned by the measurement gauge, and analyze a faulty region of the circuit board according to the record of test data and the measurement data.

Circuit board testing device and method thereof

Embodiments of the present invention provide a metadata querying method and apparatus. The method includes: sampling at least one piece of first metadata from to-be-searched-for metadata; using at least a part of feature values in each piece of the sampled first metadata as an index, and searching a sparse index table preset in a memory for a corresponding container identifier; selecting, according to the number of times that a same container identifier is found, a container corresponding to a container identifier that meets a set condition; loading metadata in the selected container into a metadata cache; and searching the metadata cache for a data block that is the same as the to-be-searched-for metadata. In the embodiments of the present invention, querying performance can be improved and occupied memory space can be reduced.

Metadata querying method and apparatus

The present invention relates to a reset method and a network device. The method includes: receiving, by an SPI Flash, a reset instruction sent by a processor; and performing reset processing corresponding to the reset instruction according to the reset instruction, where the reset instruction includes interrupting a current operation, recording interruption state information when the current operation is interrupted, and setting a current state to a state of responding to a read instruction of the processor; after finishing the reset operation, sending, by the processor, a read instruction to the SPI Flash, and receiving interruption state information sent by the SPI Flash according to the read instruction; and then determining, according to the interruption state information, whether the interrupted operation in the SPI Flash needs to be continued, and if yes, sending an instruction of continuing the interrupted operation to the SPI Flash.

Reset method and network device

In embodiments of the present invention, when a duplicate data query is performed on a received data stream, a first physical node which corresponds to each first sketch value and is in a cluster system is identified according to a first sketch value representing the data stream, and then the first sketch value representing the data stream is sent to the identified physical node for the duplicate data query, and a procedure of the duplicate data query does not change with an increase of the number of nodes in the cluster system; therefore, a calculation amount of each node does not increase with an increase of the number of nodes in the cluster system.
