An audio component of computer is prepared as connecting audio unit to detachable mechanism in detachable mode then connecting said audio unit to computer audio processing unit through wire of wire coil mechanism or connecting said audio unit to computer host through Bluetooth mode for enabling user to move audio unit conveniently.

The invention discloses a train pressure wave protection control method. The method comprises the following steps that a sensing signal flicker frequency sent by a signal identification device is received; the current train entering and exiting tunnel state corresponding to the sensing signal flicker frequency is looked up from a train entering and exiting tunnel state table; when it is determinedthat the current train entering and exiting tunnel state is in the entering tunnel state, a pressure wave protection opening instruction is sent to a pressure wave protection actuator, so that the pressure wave protection actuator closes a valve to isolate a ventilation opening between the interior and the exterior of a vehicle; and when it is determined that the current train entering and exiting tunnel state is in the exiting tunnel state, after the first preset time delays, a pressure wave protection ending command is sent to the pressure wave protection actuator to enable the pressure wave protection actuator to open the valve to open the ventilation opening between the interior and the exterior of the vehicle. According to the method, the pressure wave is prevented from being transmitted into the vehicle, adverse effects on passengers are prevented, and the passenger experience is improved. The invention further discloses a train pressure wave protection control device and equipment as well as a storage medium, which have corresponding technical effects.

The invention relates to subway communication, in particular to an isolated four-wire call one-to-two circuit. The circuit comprises an audio input differential signal, an audio output differential signal, an isolation module connected between the audio input differential signal and the audio output differential signal and used for isolation, and a signal amplification module used for amplifying an audio signal. According to the technical scheme provided by the invention, the defects of complex circuit, higher cost, mutual crosstalk between equipment and poorer call effect in the prior art canbe effectively overcome.

The invention belongs to the field of animal husbandry and specifically relates to a non-resistance cultivation method with joint application of feed strain, disinfectant bacterium and biological isolation. It is characterized in the following three aspects: (1) adding feed strain to feed; (2) spraying disinfectant bacterial suspension to environment; and (3) planting trees and traditional Chinese herbs with disinfectant function on isolation zones among houses. The invention obviously improves the feeding environment, increases the cultivation income, reduces the feed cost and cultivation risk, and provides guarantee to production of high-quality non-resistance products.

The invention relates to a small central air conditioner system used in building. It includes machine room for setting air conditioner, wind tunnel beside the machine room, air inlet connecting with air conditioner, outlet and outlet cavity separating outlet from inlet and connecting with gas. The invention solves air entering and discharge blending, influence of hot air discharged by this air conditioner or others, which can lead to bad refrigeration effect, energy waste and other technical problems. The air conditioner is installed conveniently and is used economically.

The invention relates to a construction method of the bottom seat plate of the ballastless track, which belongs to a construction process method of tracks. The purpose of the invention is to provide a reliable construction method of the bottom seat plate of the ballastless track on bridges to meet the quality and accuracy requirement of the bottom seat plate of the ballastless track. The construction method comprises the following steps: step one, firstly, the bridge floor is checked and accepted and assessed before planking; secondly, the stakingout connecting line of the bottom seat plate is measured; thirdly, the connection of the fixed bolt is arranged; fourthly, a sliding layer with two cloth and one film is laid on the bridge floor of the box-beam bridge; step two, a hard plastics foam layer is laid on the two ends of the beam slot; step three, a post casting strip connector is installed; step four, firstly, tooth socket welding studs are installed; secondly, bottom seat plate reinforcing bars are installed; step five, bottom seat plate mould plates are installed; step six, the concrete of the bottom seat plate is cast; step seven, the cast post casting strip and the weldingstud tooth socket are fixedly connected, and the connection of the bottom seat plates is completed.
