A method for manufacturing a non-magnetic spatial latticed shell structure composed of carbon fiber plate members. The load-bearing member of the latticed shell structure is made of non-magnetic carbon fiber plate, and joints are made of non-magnetic titanium alloy material. The magnetic shielding layer is provided on the roofing system above the structural layer, and a non-magnetic space with a magnetic field strength lower than 1 nT is formed inside the structure. The load-bearing members are fixed by two carbon fiber limb plates in the form of inter-limb connection and forms an hollow rectangular built-up section; and the joint comprises a titanium alloy gusset plate, a titanium alloy bolt group, and a carbon fiber limb plate; the magnetic shielding layer of the roofing system comprises a shielding layer pad, a shielding layer, a shielding laminate, a buffer layer, a permalloy plate, and a batten.

An electromagnetic field generating apparatus for treating pathological cells, in particular with tumor suppression function. The ratio of static magnetic field to alternating magnetic field is in the range of 0.5-2.5, and the total intensity is in the range up to 100 mT. It provides non-invasive low toxicity and side effects, significantly inhibiting a plurality of tumors, influencing the intracellular superoxide radical content, and promoting cell autophagy. The mechanism of action of the magnetic field is on the electron spin energy levels and consequently on free radical concentration. Additional magnetic field having frequency up to 100 MHz and intensity down to microTesla range can be also used to improve the antitumor efficacy in combination with the static as well as the extremely low frequency electromagnetic field (1-300 Hz) influencing the spin hyperfine resonance. A combination method is also provided of a power-frequency electromagnetic field generating device and a platinum-based medicine.

Apparatus for treating pathological cells

Provided is a sheet-shaped nitrogen-phosphorus co-doped porous carbon material, prepared and obtained according to the following method: mixing aniline and hexachlorocyclotriphosphazene, undergoing a closed reaction for 2-24 h at a pressure of 1-10 MPa and a temperature of 140-260&#xb0; C., then pressure is released to atmospheric pressure and steam drying is performed to obtain a solid substance; under inert gas protection, the obtained solid substance is treated for 1-6 h at a high temperature of 400-1000&#xb0; C., and the finished product is obtained; the sheet-shaped nitrogen-phosphorus co-doped porous carbon material thus provided has excellent electrical properties and may be used for fabricating capacitor electrodes and especially supercapacitor electrodes; thus it may be used in capacitors and especially supercapacitors, and has great application potential and industrial value in the field of energy storage.

Sheet-shaped nitrogen-phosphorus co-doped porous carbon material and method for preparation thereof and use thereof
