The invention discloses a sorting and conveying device for tile films. The device comprises a conveying device and a controller, and further comprises a sorting device arranged on one side of the inlet of the conveying device; the sorting device comprises a sorting frame, a sorting table arranged on the sorting frame and side plates arranged on the two sides of the sorting table, wherein at leastone baffle is arranged on the sorting table; the sorting table comprises rollers arranged in parallel between the side plates and limiting rods arranged between any two rollers; and the conveying device comprises a conveying table, a fixing arm and a positioning piece; the conveying table is at the same horizontal height as the sorting table, the fixing arm is arranged on the conveying table, andthe positioning piece is matched with the fixing arm. The device aims to provide the sorting and conveying device for the tile films, the tile films are effectively aligned and sorted in the conveyingprocess, and later packing is facilitated.

The invention provides a novel heat-insulation combustion auxiliary device for an internal-combustion engine. The device comprises an exhaust gas recirculation (EGR) pump, a high-pressure gas pipe, a high-pressure gas track, exhaust gas distributing pipes, electrically-controlled gas nozzles, an EGR pipe and an ECU; the electrically-controlled gas nozzles are connected with the high-pressure gas track through the exhaust gas distributing pipes; the high-pressure gas track is connected with the EGR pump through the high-pressure gas pipe; when proper heat insulation is required to be performed on the engine, the ECU issues a command, the electrically-controlled gas nozzles mounted on a gas cylinder wall are opened, high-pressure engine exhaust gas is sprayed in, a vortex rotating around the central line of a gas cylinder is produced through movement relative to a cylinder liner, and the rotating direction of the vortex is identical with the direction of a vortex formed by a gas channel in a pit of a combustion chamber, so that vortex flow zones are formed above the top surface of a piston and nearby heat-transfer surfaces such as the surface of the cylinder liner and the like, proper insulation is performed on the wall surface of the combustion chamber and a high-temperature combustion area, wall surface heat transfer is reduced, and the low-heat-dissipation combustion process is realized. A certain degree of EGR is realized, the combustion temperature is reduced, and the NOx emission is reduced.

The invention provides a penicillin V acylase mutant, an encoding array, a recombinant expression vector, a genetically engineered bacterium and application. Penicillin V acylase derived from Bacillussphaericus is mutated, the specific activity of the obtained mutant PVA-3 is improved by nine times, the immobilization activity is improved to 820U / g from 92U / g, and after being incubated for one hour under a condition of 30% penicillin V sylvite, the mutant has activity residue of 89.1%; the reaction time that the immobilized mutant PVA-3 is adopted to prepare 6-APA (6-Aminopenicillanic Acid) by splitting 25% penicillin V under a condition that the pH value is 6.0 at 25 DEG C is shortened to 60 minutes from 180 minutes, a substrate conversion rate is increased to 99.5% or greater, the activity is not greatly lost after continuous use for 600 times or greater, and good operation stability can be achieved. By adopting the mutated PVA-3, the production cost can be greatly reduced, the production efficiency can be improved, and the mutant is applicable to industrial application.

The invention provides a mobile phone, comprising: a detection module, used to detect the first value of the distance between the mobile phone and the user's head at the first moment during the dialing process of the mobile phone; a comparison module, used to compare the first value of the distance with the The preset distance value generates a first comparison result; the control module is used to control whether the mobile phone stops establishing a dial-up connection during the dial-up process according to the first comparison result. The invention also provides an operation method of the mobile phone. The invention can effectively reduce the chance of the user suffering from the strong radiation of the mobile phone.

The invention discloses a light spot blurring special effect implementation method. The periphery of an original image is filled with black pixels so that the size of the original image can be filled to a predetermined size and an original filled image can be obtained, a light spot material image is subjected to zooming so that a zooming material image can be obtained, a weight image is constructed according to a preset weight lookup table, then, fast Flourier transform is performed on the original filled image, the zooming material image and the weight image, an original matrix, a material matrix and a weight matrix are respectively obtained through calculation, a light spot matrix is obtained through calculation, finally, fast Flourier transform is performed on the light spot matrix so that a light spot effect image can be obtained, an algorithm is simple and fast, the processing speed of the algorithm is 10 times higher than that of an existing algorithm, a large number of computing resources are saved, meanwhile, the expressive force of a common digital photo is substantially increased, and hardware cost does not need to be increased.
