Abstract: An IGCC fuel component analysis and calorific value measurement system, the fuel components can be effectively measured by an infrared instrument and a chromatographic instrument; the multiplex redundant measurement is combined, two syngas is sampled by two sampling devices, two groups of measuring instruments are arranged, the multi-channel calculation of calorific value improves the reliability of calorific value control, and the measurement and process problems are effectively found by calorific value comparison, guaranteeing the effective output of calculated values in the fault state of the instrument, improving the calculation accuracy of calorific value, accurately analyzing the fuel components and calculating the fuel calorific value, and ensuring the stability of the calorific value regulation system and the stable operation of gas turbine; the multi-directional, diversified and multi-security instrument and the introduction of comparison between measured and calculated calorific values can effective

Abstract: A method for annotating a target web page is performed at a server by: receiving an annotation obtaining request from a first terminal associated with a first member of an online chat group; identifying a first web page annotation and a first annotation position of the first web page annotation in a target web page; returning the first web page annotation and the first annotation position to the first terminal; receiving, from the first terminal, a second web page annotation and a second annotation position of the second web page annotation in the target web page; and forwarding the first and second web page annotations and the first and second annotation positions to a second terminal for display on the target web page at the second terminal in response to receiving a second annotation obtaining request from the second terminal.
