Abstract: Disclosed in the present invention are a superconducting protection method, a superconducting protection device and a superconducting system. The superconducting protection method comprises the following steps: obtaining a working parameter of a superconductor; comparing the working parameter of the superconductor with a preset value; and when the working parameter of the superconductor exceeds the preset value, issuing an instruction, wherein the instruction is used to cause the superconductor to reduce a field. The superconducting protection method above may compare a working parameter of a superconductor with a preset value. When the working parameter of the superconductor exceeds the preset value, an instruction is issued to reduce a field of the superconductor, thereby reducing the amount of energy in the superconductor, and preventing the superconductor from overheating during a quench. Moreover, by means of setting the preset value, it may be ensured that a field reducing operation is started before the superconductor is at risk of quenching.

Abstract: Disclosed is a gas-tight environment-based high pulse current generation device having a nanosecond-scale rise time, the device comprising a gas-tight cavity having a pressure greater than or equal to the normal atmospheric pressure. An energy storage capacitor, a waveshaping resistor, and discharging switches are installed within an environment having a sealed gas. Each element thus has superior insulation and withstand voltage properties, and a gap between the discharging switches is further reduced, thereby further reducing the inductance of the discharging switches. In addition, since discharge occurs in the same gas-tight environment, a waveshaping capacitor, the resistor, and the discharging switches can be installed in a compact manner, and moreover the gap distance of the discharging switches and wire connection distances between the energy storage capacitor, the waveshaping resistor, and the discharging switches reduce the inductance of connecting wires in a loop, thereby effectively generating a high pulse current wave having a nanosecond-scale rise time.

Abstract: Disclosed are a method for preparing a transparent wood material by means of an organic solvent, and a transparent wood material prepared thereby and the use thereof. The specific preparation steps are as follows: first drying a veneer sample at 105 ± 5ºC, then placing same into an aqueous ethanol solution, carrying out extraction on the dried veneer sample under a condition of 85 - 95ºC, and then washing same with an aqueous ethanol solution; further carrying out retention bleaching on same using an aqueous hydrogen peroxide solution; and finally filling holes and voids of the wood material with a polymer matrix to obtain a light-permeable wood-based material. By using ethanol to dissolve lignin at a low temperature, the original structure of the wood material can be kept intact, the removed lignin is closer to the original lignin, and the prepared transparent wood material has a higher optical transmissivity.The use of a chlorine-free method to remove lignin is environmentally friendly, and, by means of distillation, all of the ethanol can be recovered, which reduces the cost. The prepared transparent wood material can be applied to light-permeable buildings and transparent solar cell windows.
