摘要： A controllable splitting method comprises: electrically connecting a photoconductive switch between input and output ends of a current pulse; connecting a time domain signal of the input current pulse to an external triggering port of a pulse laser; emitting a laser pulse to irradiate the switch; when no current pulse is input, failing to receive an external triggering signal and not outputting the laser pulse, the switch being in an off state without the irradiation of the laser pulse, and no current being output; when the current pulse is input, triggering the pulse laser to synchronously output the laser pulse on a time domain, irradiating the switch so that the switch is in an on state and the current pulse is output; and forming, at the output end, a current pulse signal synchronous with a time domain of the input end and having a split waveform.

摘要： A high temperature fixture, said fixture comprising: at least three noble metal electrodes arranged in parallel, among which two adjacent noble metal electrodes are used for clamping a test sample; noble metal wires connected to the noble metal electrodes at one end, and to a test device at the other end for transmitting test signals generated by the test sample to the test device through the noble metal electrodes; and a thermocouple for measuring the temperature of the test materials.
