This invention discloses a side-mounted magnetic stirring device and method. The device includes a storage unit, a spherical stir bar placed inside it, and a magnetic stirrer disposed on its outer wall. The spherical stir bar has an embedded magnet, and the magnetic stirrer drives the spherical stir bar to roll and / or rotate through a magnetic field. The outer wall of the storage unit may be provided with a slide rail or guide groove, and the magnetic stirrer can move axially via a slider or roller; it may also include a fixing component and an adjusting screw for connecting the magnetic stirrer and the liquid-pushing piston and adjusting their relative positions. The method includes placing the spherical stir bar inside the storage unit, starting the magnetic stirrer to drive stirring, and making the magnetic stirrer move synchronously with the liquid-pushing piston. This invention requires no modification to the opening, does not occupy bottom space, has no leakage risk, and is easy to assemble and disassemble, making it particularly suitable for tubular liquid storage units with limited bottom space or requiring temporary stirring.

The invention relates to the technical field of skirting line construction, and particularly discloses a quick-mounting cement pressure plate skirting line construction method and a skirting line. The quick-mounting cement pressure plate skirting line construction method comprises the following steps that S1, base layer treatment is conducted, specifically, the wall root and the ground of a construction area are cleaned; step S2, fixing a cement pressure plate; step S21, providing a prefabricated cement pressure plate; s22, putty is smeared on the surface of the wall root; s23, the cement pressure plate is attached and positioned to the surface of the wall root through putty; s24, the cement pressure plate is fixed to the wall root through a fixing piece; step S3, water-resistant putty construction; s4, surface layer coating is brushed, specifically, the putty layer is brushed with the coating; and S5, finished product protection, wherein a temporary guardrail or a warning tape is arranged before the surface of the coating is dried. The cement pressure plate is adopted to replace traditional mortar, the construction effects of being high in construction speed, free of maintenance and not prone to cracking are achieved, and on the premise that the construction quality is guaranteed, the construction period can be shortened, and the construction cost can be reduced.

A direct current contactor capable of executing large current breaking for multiple times comprises a shell, a driving system, a contact system, an electronic ignition assembly and a telescopic action execution assembly. The action execution assembly is arranged in the shell corresponding to the movable contact plate; the electronic ignition assembly is arranged at the top of the shell corresponding to the action execution assembly; the electronic ignition assembly comprises an electronic ignition tube shell and at least two electronic ignition tubes, and an exhaust channel communicated with the exterior of the shell is formed in the shell wall of the electronic ignition tube shell. The action execution assembly is in sealing contact with the inner wall of the electronic ignition tube shell, and when the contact system is normally switched on and switched off, one end of the action execution assembly located in the electronic ignition tube shell seals the exhaust channel; in a normal working state, the action execution assembly and the electronic ignition assembly do not act, and the driving system drives the contact plate to move, so that the contact system performs normal opening and closing. Through the multiple independent electronic ignition tubes and the exhaust channels, multiple times of large-current breaking are achieved, and the breaking capacity and the utilization rate of the contactor are improved.

The application relates to the technical field of artificial intelligence, in particular to an intelligent question and answer method and device, computer equipment and a storage medium. The method comprises the following steps: in the case that an intelligent reply event is detected, target user data and a target question and answer analysis model are acquired; the target question and answer analysis model is deployed on a function calculation platform, and the target question and answer analysis model is obtained by updating an existing question and answer analysis model in the case that a business changes; and reply information is generated according to an analysis result of the target question and answer analysis model on the target user data. The application can improve the accuracy of intelligent question and answer.
