The present disclosure provides a device and method for measuring a correlation between fatigue performance and a microstructure of a one-dimensional (1D) nanomaterial in situ in a transmission electron microscope (TEM), belongs to the technical field of in-situ testing and characterization of microstructures of nanomaterials. The device includes a chip part, a supporting part, and a control circuit. The supporting part is a bracket and a cable disposed on a transmission sample holder, and the circuit part consists of cables connected to the chip and a power supply capable of applying different waveforms, variable voltages, and variable frequencies. This design breaks through a traditional mechanical stress-driven fatigue performance test method, and achieves controllable adjustment of different amplitudes and cycles by using an electric field formed by a voltage and adjusting a voltage size and frequency, such that the 1D nanomaterial vibrates in the electric field to achieve fatigue performance testing.

The disclosure discloses a receiving end/signal transmitting method, a pure-optical active cable and an active cable. The receiving end includes a first high-speed signal optoelectronic transmission module and a first low-speed signal optoelectronic transmission module; a power supply port of the first high-speed signal optoelectronic transmission module being connected with a high-speed signal line of the receiving end, and a power supply port of the first low-speed signal optoelectronic transmission module being connected with the high-speed signal line. When the high-speed signal line of the receiving end is connected to a termination power supply of a display device during signal transmitting, the first high-speed signal optoelectronic transmission module and the first low-speed signal optoelectronic transmission module are capable of acquiring a power supply signal from the high-speed signal line to solve power supply in the receiving end of the pure-optical active cable.

A method utilizing cold welding to prepare grain boundaries having different included angles includes using a device including a support member. Two bent members are arranged opposite to each other in the support member. One ends of the two bent members are both fixedly connected to the support member, one end, away from the support member, of any bent member is fixedly connected to a first sample, one end, away from the support member, of the other bent member is fixedly connected to a second sample, and the first sample and the second sample are arranged corresponding to each other. The bent member includes a first metal sheet and a second metal sheet having different thermal expansion coefficients. An angle between the first sample and the second sample during butt welding can be controlled by changing an included angle of a bimetallic sheet.

Selecting tables for compression by threshold statistical values. Identified tables are reordered according to fields having the lowest cardinality to increase the size of character strings replaced by keys during compression. Field locations are mapped between the original table and the reordered table. Dictionary-based compression is performed on reordered tables.
