The invention discloses a novel assembly method of a hot aerosol coolant and a hot aerosol generating agent, which comprises the following steps: step 1) pre-forming the hot aerosol coolant into small pieces; step 2) making step 1) into small pieces The thermal aerosol coolant in a discrete state is mixed with the thermal aerosol generator, wherein the amount of the thermal aerosol coolant is 5% to 50% of the thermal aerosol generator; step 3) pressing, casting or In bulk, assemble the mixture into cartridges for fire extinguishing equipment. The novel assembly method of the present invention can make the thermal aerosol coolant timely and fully exert the heat-absorbing and cooling effect when the thermal aerosol generating agent undergoes a strong exothermic reaction; at the same time, it does not destroy the continuity of each active component of the thermal aerosol generating agent Therefore, it will not have a great impact on its combustion and injection performance, which ensures the effective, fast and safe release of the hot aerosol generating agent.

The invention relates to a tennis ball collection device for tennis courts, which effectively solves the problem that it is inconvenient to pick up tennis balls near the block and that picking up the ball at the same time will affect training; There is a reel between the side plates, there is a conveyor belt on the reel, and there is a Velcro on the upper surface of the conveyor belt; there is a ball-catching device between the two side plates, and the ball-catching device includes two support rings, which are fixed between the two support rings. The ball receiving bucket is equipped with a rotating shaft in the front and rear directions inside the ball receiving bucket, and there are a plurality of ball dials evenly distributed on the circumference of the rotating shaft; a bottom plate is fixed between the front and rear support rings, and a box is arranged above the bottom plate. The side and the front side are open, and the side wall of the box is provided with through holes; the box can move back and forth left and right; the bottom of the box is equipped with multiple vertical guide rods, which can move up and down and reset downward; The left and right movement of the body can drive a plurality of guide rods to move up and down, and the present invention can pick up balls and clean them without feeling.

The invention relates to a method and device for monitoring the seepage of an underground diaphragm wall of a foundation ditch of a building. The method comprises the following steps of: (1) constructing a borehole at the center of the foundation ditch, arranging a power supply electrode A at the bottom of the borehole, and arranging another power supply electrode B at a place 7-10 times of the length of the foundation ditch away from the center of the foundation ditch; (2) arranging detection points on the ground surface along the underground diaphragm wall in a manner of surrounding the foundation ditch, and arranging a measuring electrode M and a measuring electrode N at each detection point along the direction vertical to the underground diaphragm wall; (3) marking out planar positions with abnormal formula (shown in a drawing); (4) marking out vertical elevations with the abnormal formula (shown in the drawing); and (5) obtaining positions corresponding to the planar positions with the abnormal formula obtained in the step (3) and the vertical elevations with the abnormal formula obtained in the step (4), thereby obtaining positions in seepage. The invention further relates to a device for monitoring the seepage of the underground diaphragm wall of the foundation ditch of the building. By using the method and device for monitoring the underground diaphragm wall of the foundation ditch of the building, the damage to an underground diaphragm wall body can be avoided, and the operation is very simple and convenient.

The invention provides an interferometric phase filtering method based on a difference chart and compensation filtering. The interferometric phase filtering method comprises the steps of: firstly, extracting principal components of interferometric phases from an input interferometric phase image through frequency domain filtering based on the differential chart, so as to reduce density of interferometric fringes in the residual interferometric phase image and facilitate subsequent processing; and secondly, performing compensation filtering on the residual interferometric phase image, wherein compensation filtering adopts BM3D filtering taking a phase derivative variogram of the residual interferometric phase image as self-adaptive filtering parameters, and can better extract detail components of the interferometric phases. The interferometric phase filtering method comprises frequency domain filtering and space domain filtering, is suitable for processing the interferometric phases containing dense interferometric fringes, and can effectively filter out noise without destroying the continuity of the dense interference fringes.
