Nitrogen hybridized magnetic ordered mesoporous carbon adsorbent, and preparation method and application thereof

The invention relates to a nitrogen hybridized magnetic ordered meso-porous carbon adsorbent. The aperture of the adsorbent is within 3.8nm, the surface part of the adsorbent is graphitized, and the adsorbent comprises magnetic nano particles; the magnetic nano particles are iron oxide nano particles and iron nano particles. A preparation method of the adsorbent comprises the following steps: adding a meso-porous silicon SBA-15 template into an organic solution which contains furfuryl alcohol and ferric nitrate and is easy to volatilize, sufficiently mixing, performing thermal polymerization, subsequently carbonizing on the presence of an inert gas, finally removing silicon by using a strong alkali solution, and separating, washing and drying so as to obtain magnetic ordered meso-porous carbon; and dissolving the magnetic ordered meso-porous carbon into a strong acid solution, controlling the temperature to be less than 5 DEG C, adding aniline and ammonium persulfate, sufficiently mixing, washing and drying the complex after polymerization, and carbonizing on the presence of the inert gas so as to obtain the nitrogen hybridized magnetic ordered meso-porous carbon adsorbent. The adsorbent is high in adsorption efficiency, large in adsorption volume and short in adsorption balance time.

Method using side-scan sonar to measure tonnage of ship

The invention relates to a method using a side-scan sonar to measure the tonnage of a ship. The method comprises the following steps: when a photoelectric sensor detects that ship passing signals exist, a tow fish arranged under water is started; the tow fish scans the side of a measured water area to acquire an underwater acoustic image of an underwater part of the ship; the sailing speed and the passing time of the ship are simultaneously measured, and the length of a ship body is calculated according to the product of the ship speed and the passing time; an underwater acoustic image of a measured area is acquired by a computer connected with the tow fish; then image processing is conducted on the underwater acoustic image of the measured area, so as to extract an acoustic shielding shadow of the measured ship; the draft depth of the ship body and the width of the ship body below a water line are acquired according to a combination of a projection relationship and measured environmental parameters; the total tonnage of the ship is calculated according to the length of the ship body, the draft depth, the width of the ship body below the water line, and a square model coefficient of the ship marked on a ship-borne certificate; and the difference between the total tonnage and the net tonnage of the ship marked on the ship-borne certificate equals to the actual-load tonnage of the ship.

The invention discloses a nuclear hazard forecasting and alarming platform and method based on a GIS (Geographic Information System), belonging to the field of hazard control. The nuclear hazard forecasting and alarming method comprises the following steps of: 1.obtaining forecasting results of a wind field and a turbulence flux; 2. carrying out proliferation simulation on a nuclear hazard; 3. obtaining hazard depth, withdrawing depth, iodine taking depth, hazard area, withdrawing area, iodine taking area, hazard start time and hazard duration time of a nuclear accident; 4. judging whether the hazard depth of the nuclear accident in a set proliferation simulation region is figured out, if the hazard depth is figured out, ending the method, and if the hazard depth is not figured out, returning to the step 2; and 5. forecasting and alarming the nuclear hazard based on the GIS and issuing online in real time. The invention provides a data support for dealing with nuclear crisis, providesa scientific basis for rapidly dealing with the nuclear crisis, and scientifically evaluating the result of the nuclear hazard, thereby guiding the public to rapidly take correct safeguard measures after the public are attacked, eliminating psychological pressure and unnecessary worry and guaranteeing the social stability and the everyday routines.

Method for utilizing fingerprint as traffic ticket

InactiveCN101527054ARealize cost-free productionStop ScalpingOther printing matterIndividual entry/exit registersData informationHandling system
The invention relates to a method for utilizing a fingerprint as a traffic ticket. The method comprises the following steps that: a ticket purchaser fills in a ticket purchasing sheet; ticket-selling staff collects a fingerprint of the ticket purchaser, and stores the ticket purchasing sheet and the fingerprint of the ticket purchaser in a ticket database; a ticket processing system compares the stored information with the prior data information and judges whether the ticket purchaser is a repetitive ticket purchaser or a person with low credit standing or not; the ticket is sent to a non-repetitive ticket purchaser with high credit standing; the train number, the seat number, the departure location, the departure time and the arrival location are bond with the fingerprint of the ticket purchaser; when passengers enter a station, the passengers press the fingerprints, and according to the fingerprints, whether the passenger can enter the station or not is checked; when the passengers leave the station, the passengers press the fingerprints, and according to the fingerprints, whether the passenger can leave the station or not is checked; when one passenger traffic work is finished, the ticket processing system automatically carries out the check of passenger departure and arrival; if no passenger departure information is in the ticket database, the passenger is considered as ticket evasion; and corresponding credit standing value of the fingerprint of passenger in the ticket database is reduced.
