The invention discloses a library building method and application of a mass spectrum library for detecting carbapenem-resistant klebsiella pneumoniae producing KPC enzyme, and belongs to the technical field of laboratory medicine. The library building method comprises the following steps: S1, carrying out matrix-assisted laser desorption ionization time-of-flight mass spectrometry detection on carbapenem-resistant klebsiella pneumoniae capable of producing KPC enzyme to obtain mass spectrogram data; s2, preprocessing the mass spectrum data obtained in the step S1, and establishing a basic mass spectrum database to obtain database-established mass spectrum data; s3, performing homology analysis and characteristic peak screening on database-building mass spectrum data obtained in S2, comparing with a strain mass spectrum database, calculating a weight value and a score value, and building a database-building data packet; and S4, activating the database building data packet, storing the database building data packet into a local database, and verifying CRKP-KPC strain mass spectrum identification.

This invention discloses an isolation and protection system for rotating machinery. The isolation and protection system includes a pneumatic module and an isolation module. The pneumatic module includes a pilot valve, an air inlet pipe, and a rotating air chamber. The pilot valve is fixed, and the rotating air chamber rotates around its own axis. The air inlet pipe is connected to the rotating air chamber through a bearing. The isolation module is equipped with a rotary joint, which includes a stationary channel, an adapter, and a rotating channel that are interconnected. One end of the stationary channel is fixedly connected to the pilot valve, and the other end is fixedly connected to the adapter. One end of the rotating channel is fixedly connected to the air inlet pipe, and the other end is connected to the adapter. The rotating channel is rotatable relative to the adapter around its axis. By setting a rotary joint, this invention physically isolates the torque of the air inlet pipe and the pilot valve, preventing abnormal rotation of the air inlet pipe from being transmitted to the pilot valve and causing the housing to rupture when the bearing is damaged, thus avoiding serious economic losses and production interruptions.

The invention discloses a construction method for arranging an underground garage for an existing building based on an open caisson, and belongs to the field of building construction. According to the method, an open caisson is arranged between two adjacent existing buildings, the two ends of the cross section of the open caisson in the length direction are semicircular channels, the two sides of the cross section of the open caisson in the width direction are a plurality of arch walls continuously protruding outwards, and standard knots are formed between the opposite arch walls on the two sides. The construction method comprises the steps that the plane size of the open caisson is determined according to existing building foundation arrangement and spacing; a working pit extending to the position below the existing building is excavated; a first section of open caisson is poured in the working pit, so that the arch wall is located below the foundation beam; foundation soil is excavated, and the open caisson sinks and is poured and lengthened through the dead weight of the open caisson and the downward pressure of the existing building; the sinking and lengthening steps are repeated, and a temporary channel and a floor slab are manufactured; and the working pit is backfilled after construction is completed. According to the method, counter-force beams are omitted, floor slabs are manufactured synchronously to improve the open caisson strength and reduce the water and soil pressure influence, material transfer is achieved through the semicircular channels, and construction is efficient, safe and reliable.
