英文摘要	The invention relates to a method for detecting the content of a component in an unknown object on line. The method comprises the following steps of: breaking a trace amount of detected objects down and generating a plasma on the basis of a laser induced breakdown spectroscopy technology, collecting light emitted by the plasma, splitting the light, and performing photoelectric conversion to acquire spectrum data of a detected component and analyzing the acquired emission spectrum data of the plasma, processing the spectrum data, and calculating the concentration of the detected component, namely a detected element by directly using the spectrum of the unknown object by a self-calibration method. In the method, the laser induced breakdown spectroscopy technology is used for detecting material components on line without complicated sample preparation processes a measuring process is simple and quick simultaneously, the method is suitable for on-line analysis of materials in forms such as a solid state, a liquid state, a gas state and the like, has a wide application range and can adapt to a changeable on-line measuring environment and by the method, the accuracy of on-line detection is improved.
