The invention belongs to the technical field of lithium ion batteries, and particularly relates to a pore-forming method for diaphragms of lithium ion batteries. The method comprises the following steps: fully dissolving a pore-forming agent into a solvent so as to prepare a pore-forming agent solution; uniformly coating the pore-forming agent solution on the surface of a to-be-cold-pressed diaphragm, and carrying out baking on the diaphragm at a temperature lower than the sublimation or decomposition temperature of the pore-forming agent, so that a solvent of the pore-forming agent solution is volatilized, and the pore-forming agent is recrystallized in the diaphragm; and carrying out cold pressing on the diaphragm, and then carrying out baking on the diaphragm at a temperature higher than the sublimation or decomposition temperature of the pore-forming agent, so that the pore-forming agent recrystallized in the diaphragm is sublimated or decomposed, thereby obtaining a porous diaphragm. According to the invention, through regulating the viscosity of the pore-forming agent solution, a diaphragm with adjustably-distributed pores can be obtained, and the regulating method is simple and flexible, and wide in applicable range; and particularly, according to the invention, an efficient gradient pore distribution structure that more pores are distributed on the surface layer of the diaphragm and less pores are distributed on the inner layer of the diaphragm can be realized just through selecting an appropriate viscosity of the pore-forming agent solution..

The invention discloses a method for rapidly selecting a HEVC prediction mode based on scene switching. The method comprises the following steps of: firstly, when an input YUV file is read, recording the brightness component of each frame of image to form a gray-level image; compressing each frame of gray-level image into an index image in the M*M format by utilizing an interpolation method; calculating the average value V<average> of the M*M gray values, and comparing each gray value with the V<average> to obtain a M*M-bit binary fingerprint sequence of each frame of image; for two sequential images, comparing fingerprint sequences thereof, counting the number dNum of different binary values at corresponding positions, and generating a hash index; and, for a current frame of image, the hash index of which is greater than a threshold value T, judging that the current frame is a scene switching frame, setting the current frame to the I frame when the frame type is set, performing predication coding according to the I frame, and otherwise, not performing any operation. By means of the method disclosed by the invention, for the scene switching frame in a video, rapid detection can be carried out; furthermore, other related optimal acceleration algorithms cannot be influenced; and the coding quality cannot be changed. The method disclosed by the invention can be used together with the existing HEVC rapid prediction algorithm.

The invention discloses a method for solving the inverse kinematics of a 6-degree-of-freedom manipulator, which relates to the field of industrial robots. The method first uses the Monte Carlo method to assign a certain number of random samples to the joint space of the manipulator, and calculates the corresponding For the position of the end of the manipulator, the samples that meet the target position conditions are selected as part of the initial population of the genetic algorithm; the other part of the initial population of the genetic algorithm is composed of random individuals, and then the kinematic inverse solution of the manipulator is solved by the genetic algorithm. On the one hand, the present invention optimizes the initial population of the genetic algorithm through the Monte Carlo method, effectively improving the search speed and search success rate of the genetic algorithm; search capability.

The invention discloses a method for preparing a culture medium with Chinese herbal medicine dregs. The method comprises the steps as follows: after the Chinese herbal medicine dregs are accumulated for anaerobic fermentation, compound bacteria of bacillus subtilis and aspergillus niger as per the bacterial content are added and mixed uniformly to enable the bacterial content concentration to be higher than 500 thousands bacteria per gram, then syrup is sprayed and mixed uniformly, after accumulation, the accumulated materials are covered with a black plastic film until the highest temperature in the accumulated materials reaches 55 DEG C, the black plastic film is removed for aerobic fermentation until the moisture content of the accumulated materials is lower than 45%, and the culture medium can be obtained through accumulation and ageing. The culture medium prepared with the method is low in salinity, low in EC value, large in cation exchange capacity and high in acid-base buffering capacity and saline-alkaline buffering capacity; meanwhile, by the aid of the culture medium, the soil looseness degree, the fertilizer keeping and water holding capacity and the heat insulation and ventilation capacity can also be improved; the culture medium is suitable for most of crops, even flowers, plants and the like with very strict cultivation requirements, the culture medium is suitable for mixing with any materials to be prepared into required media without limitations, and salinization conditions caused by excessive use can be avoided.
