The invention provides improved tabletting equipment. The improved tabletting equipment comprises a pressing plate; a top plate is arranged rightly below the pressing plate; a base is arranged below the pressing plate and the top plate; a power device is arranged in the base; a first lifting rod is arranged between the pressing plate and the power device; a second lifting rod is arranged between the top plate and the power device; multiple convex molds are arranged on the lower end surface of the pressing plate; multiple concave molds are arranged on the upper end surface of the top plate; andthe convex molds on the descended pressing plate just fall into the concave molds on the ascended top plate. The improved tabletting equipment has the following beneficial effects: through the design, mutual acting force between the convex molds and the concave molds is obviously increased, so that catalysts in the concave molds are suffered from a higher pressure effect, and molding of the catalysts by tabletting is facilitated. The lifting times of the convex molds and the concave molds can be reduced, so that the time needed by tabletting is obviously shortened, and the tabletting efficiency is improved.

The invention belongs to the technical field of the on-line detection and analysis of electric power system low-frequency oscillation. The invention provides a method for quantitatively evaluating the contribution degree of an electric generating set associated with a node participating in the oscillation of certain mode to the oscillation power of the mode in a power system, only based on the information of Wide Area Measurement System. In the method, a concept of node contribution factor is first proposed based on injection active oscillatory power, and then according to the amplitude of injection active oscillatory power and the relative phase position among active oscillatory power curves under certain frequency mode, an analysis and calculation method is provided corresponding to thenode contribution factor of the frequency mode, and the homology and grouping of the node are realized at the same time. The method is applicable to a system without an electromagnetic ring net and consideration for losses and can also be used for an actual electric power system which has the above characteristics through simplification.

The invention discloses a preparation method of microencapsulated zirconium phosphate. The method comprises steps as follows: zirconium phosphate with the particle size being 0.8-1.2 mu m is evenly dispersed in a solvent, and a zirconium phosphate dispersion liquid is obtained; meanwhile, a reaction reagent is added to the zirconium phosphate dispersion liquid, the mixture is mechanically stirred and subjected to reflux at the temperature of 50-180 DEG C, a hybrid crosslinking reaction occurs, the reaction time is controlled within 1-36 h, and after the reaction ends, microencapsulated zirconium phosphate is obtained through washing and freeze-drying. The microencapsulated zirconium phosphate is prepared from zirconium phosphate with a microencapsulation technology, and the preparation technology is simple, easy to operate and suitable for industrial production; a prepared microencapsulated zirconium phosphate flame retardant has the more optimized and reasonable flame-retardant progress control and the more effective and lasting flame-retardant effect; prepared microencapsulated zirconium phosphate is added to a PC matrix, and the prepared halogen-free flame-retardant PC is easy to process and mold, halogen-free, environment-friendly and better balanced in mechanical performance and flame-retardant performance.

The invention provides a light module power supply control method, which is applied to a light module power supply control system consisting of a light module, a power supply control module and a system control module for controlling optical fibers. The method comprises the steps that the plugging state of the light module is detected, and if the light module is not plugged, forbidden signals are output for closing a conducting path of the light module; if the light module is plugged, whether the optical fibers are in position or not is detected, if the optical fibers are in position, gating signals are output to the power supply control module for conducting the conducting path of the light module; if the optical fibers are not in position, the forbidden signals are output for closing the conducting path of the light module; whether receiving signals of the light module are lost or not is detected, if the receiving signals of the light module are lost, the forbidden signals are output for closing the conducting path of the light module; if the receiving signals of the light module are not lost, the gating signals are output to the power supply control module for conducting the conducting path of the light source module. The light module power supply control method has the advantages that safety and reliability are realized during the plugging and the unplugging of the light module, the control is more convenient and reasonable, the damage to the light module is avoided, the existence of risk during the hot plugging and unplugging is reduced, and the energy consumption of the light module in the non-working state is reduced.
