The invention provides a cycle division method and apparatus of a sedimentary stratum. The method comprises: pretreatment is carried out on obtained data reflecting an original stratum sedimentary environment and a lithological change to obtain pretreatment data; empirical mode decomposition is carried out on the pretreatment data to obtain a plurality of intrinsic modal functions; conversion is carried out on each intrinsic modal function to obtain an instantaneous frequency curve corresponding to the intrinsic modal function; according to the instantaneous frequency curve, a Milankovitch cycle curve is obtained; on the basis of the Milankovitch cycle curve, an accommodating space changing curve is obtained; and according to the accommodating space changing curve, an accommodating spatialascending half cycle and an accommodating spatial descending half cycle are obtained. According to the division method, the calculation process is objective and the influence on the process by the human factor is low. And the division method has high operability.

The invention discloses a method for calculating the distribution network inspection period based on multidimensional matrix decision-making. The operation is as follows: collect distribution network sample data, and the distribution network data includes health index and importance index data; Empirical health and importance evaluation; standardize the collected data; after obtaining the standardized data, calculate its information gain rate, build a decision tree, and then determine the health and importance of the line, and then according to the health and the importance decision matrix to obtain the inspection period. The invention takes the indexes in various fields of the line as a reference, and greatly reduces the subjectivity of manual judgment. Using the judgment of professionals as a classification sample, fully expand the use of the rich experience of professionals, greatly reduce manpower input, enable the calculation of the inspection cycle of the entire network and the whole line, and use real-time / quasi-real-time / recent indicators for automatic discrimination , which greatly reduces the hysteresis of the judgment result.

The invention discloses a detection method for iron ore powder assimilation reaction temperature and assimilation reaction speed, belonging to the technical field of iron ore powder sintering. A detection method of iron ore powder assimilation reaction temperature and assimilation reaction speed of the present invention uses a detection device equipped with electrodes to detect the electrical signal and temperature change with time during the assimilation reaction process of iron ore powder sample , judge the assimilation temperature and the time t required for the reaction process through the change of the electrical signal, and then use the time t and the distance δ between the electrodes to calculate the assimilation reaction rate. The invention provides a detection method for iron ore powder assimilation reaction temperature and assimilation reaction speed, which can accurately detect the iron ore powder assimilation temperature and assimilation reaction speed.

The invention provides a method and device for determining an ideal power generation progress indicator of a power plant. The method comprises the steps that maximum output and maintenance information of all units of the power plant in every month are acquired; predicated power generation load of the whole network in every month is acquired; the power generation capacity of the power plant in every month is determined according to the maximum output, maintenance capacity and maintenance lasting days of each unit as well as the number of days in every month; the total amount of the power generation capacity of the power plant from January to the m month is determined according to the power generation capacity of the power plant in every month and the obtained annual power generation capacity of the power plant; a contract progress indicator of the m month power generation capacity of the power plant is determined according to the specific value of the total amount and the annual power generation capacity; the ideal power generation progress indicator of the power plant in the m month is determined according to the contract progress indicator, the predicated power generation load of every month, the number of days in the whole year and the number of days from January 1 of the year to the last day of the m month. According to the method and device for determining the ideal power generation progress indicator of the power plant, the actual operation condition of the grid is considered, and the provided ideal power generation progress indicator is more reasonable.
