The invention discloses a method for analyzing the salification and scale formation component content of the vanes of a steam turbine, which comprises the following steps: scale sample is weighed and dried, and water content is measured; the ignition increment S1 percent and decrement S2 percent of the scale sample at 450 DEG C and 900 DEG C are measured; the contents of sodium ions and potassiumions in the acid soluble scale sample component are measured; the content of chloride ions CI<-> percent, the content of fluorine ions F<-> percent, the content of sulfuric anhydride SO3 percent, thecontent of phosphoric oxide P2O5 percent, the content of ferric oxide Fe2O3 percent, the content of alumina AI2O3 percent, the content of copper oxide CuO percent, the content of calcium oxide CaO percent and the content of magnesium oxide MgO percent in the scale sample are measured; the full silica content in the alkaline fusion component of the scale sample is measured and presented by SiO2 percent; the percentage contents of NaCI, NaF and Na2O are calculated; compared with the current method for analyzing the scale and corrosion products of heat power plants, the adoption of the method ofthe invention to analyze the salification and scale formation component content of the vanes of the steam turbine can obtain more accurate and reliable data.

The invention provides a method and system for multi-body model form control. The method comprises the steps of reading a form file comprising controllable model parameters; obtaining a subsystem configuring file selected by a user and writing the model parameter information in the read form file to a new subsystem file needing to be configured; and generating a new assembly file by utilizing preset data information and the subsystem file, storing the new generated subsystem file and assembly file under a set path and copying a needed template file and other property files to the set path so as to generate a full vehicle model database for simulating calculation. By utilizing the method, the model parameter-updated subsystem file, the assembly file and a database folder containing all the needed files can be automatically generated; the database can be directly used for simulation without referencing other files; the whole model generating process is automatically completed by the system; and therefore, the obtaining is quicker and more accurate.
