Disclosed is an operation and maintenance method and system for automatically and uniformly managing nodes of bastion host. No matter distribution of user permission, daily deployment of machine monitoring and network monitoring or batch management of daily operation and maintenance, the operation and maintenance method and system can be abstracted as follows: master control dispatches a Master of a certain area node to issue and execute a certain task, and unified management is naturally achieved; the design concept can be continued subsequently. A Master host in the node serves as a master controller of the node, and related contents including a tool script library, a crontab task and a configuration file are preset in a Redis of the node in advance; when a new machine is accessed to a certain node, the new machine is configured to perform Salt-Master access management of the node where the new machine is located, and the corresponding machine is controlled to complete the corresponding task through a takeover program; therefore, unified and automatic management is realized.

A pneumatic proportional valve includes a torque motor and a pneumatic rotary valve. The torque motor includes permanent magnets, magnetically permeable yokes, an upper armature, a lower armature, an upper skeleton, a skeleton column, a lower skeleton, an exciting coil, a coil skeleton, a spring support, a spring plate and load springs. The torque motor has a single coil structure with an axis of the exciting coil coinciding with a rotation axis of the armatures, and the coil is arranged between the upper armature and the lower armature. The torque motor has the upper armature and the lower armature, and the upper armature and the lower armature have a total of four armature arms, which can form eight air gaps with an upper one and a lower one working in pair, form four pairs of magnetic circuits in parallel with each other under the excitation of a control coil.

Pneumatic proportional valve with high frequency response and low power consumption

A novel K (capsular antigen) serotype ofand an application thereof are provided. A novel K (capsular antigen) serotype of, which was deposited at the China General Microbiological Culture Collection Center (Institute of Microbiology, Chinese Academy of Sciences, No. 3, Yard 1, Beichen West Road, Chaoyang District, Beijing) on Feb. 20, 2019, with a deposit number of CGMCC No. 17249, wherein the K epitope of thehas a sequence set forth in Sequence No. 1. The novel K serum is highly specific, and can be used to conveniently and quickly detect a novel K serotype of(O4:KUT-recAin) which has a rising infection rate in recent years. It provides important detection techniques for the pathogen diagnosis, monitoring and prevention of infectious diarrhea.
