    摘要: An exhaust gas analysis method comprises applying a laser beam to the exhaust gas discharged from an internal combustion engine, receiving the laser beam that has passed through the exhaust gas, and measuring the concentration of any of the components contained in the exhaust gas based on the received laser beam. The exhaust gas analysis method further comprises detecting the absorption spectrum of the laser beam absorbed in the exhaust gas by using the received laser beam, calculating the concentration of the specific gas component by using the absorption spectrum, calculating the temperature of the exhaust gas by using the absorption spectrum, calculating the pressure of the exhaust gas by using the absorption spectrum, correcting the calculated concentration of the component contained in the exhaust gas by using the calculated temperature, correcting the concentration by using the calculated pressure, and outputting the true concentration value.

    摘要: In an aspect of the present invention, a facilities control system includes a simulation section which carries out a simulation of a time change of a status of an object of a target based on a status data showing the target status in the facilities by using a facilities model; and a display section which displays a simulation result. The facilities model includes a plurality of nodes, in each of which a process is carried out the target based on a first condition, which is set to the node to determine a throughput of the process in the node. A plurality of links, each of which connects between two of the plurality of nodes, and in each of which a process is carried out the target based on a second condition, which is set to the link to determine a throughput of the process in the link.

    摘要: An exhaust gas analysis method comprises applying a laser beam to the exhaust gas discharged from an internal combustion engine, receiving the laser beam that has passed through the exhaust gas, and measuring the concentration of any of the components contained in the exhaust gas based on the received laser beam. The exhaust gas analysis method further comprises detecting the absorption spectrum of the laser beam absorbed in the exhaust gas by using the received laser beam (S1), calculating the concentration of the specific gas component by using the absorption spectrum (S2), calculating the temperature of the exhaust gas by using the absorption spectrum (S3), calculating the pressure of the exhaust gas by using the absorption spectrum (S4 to S6), correcting the calculated concentration of the component contained in the exhaust gas by using the calculated temperature (S7), correcting the concentration by using the calculated pressure (S8), and outputting the true concentration value (S9). Accordingly, the exhaust gas analysis method is substantially insensitive to variation in pressure and temperature of the exhaust gas and capable of calculating and analyzing the concentration of any of the components contained in the exhaust gas in an accurate, realtime manner.
