Abstract: An example method for managing data configuration information across data repositories includes receiving, by a target data repository, data for replication from a source data repository; generating, by the target data repository and based on the receiving the data, target repository identifier information for the data, the target repository identifier information enabling clients to access the data on the target data repository and different from source repository identifier information; accessing, by the target data repository, the source repository identifier information that enables clients to access the data on the source data repository; providing, by the target data repository at a first time, the target repository identifier information for accessing the data on the target data repository; and providing, by the target data repository at a second time, the source repository identifier information for accessing the data on the target data repository.

Abstract: In a sensing session establishment process, an access point sends a first frame to a first station, where the first frame includes first information, the first information indicates a first role of the first station in a sensing session, the first role of the first station in the sensing session is a transmitter and/or a receiver, and the first station is a station participating in the sensing session in a second station associated with the access point; and the access point receives a second frame from the first station, where the second frame includes confirm information for the first frame.

Abstract: A method for inhibiting a flash point of trans-1,2-dichloroethylene (T-1,2-DCE) and a use of T-1,2-DCE are provided. The T-1,2-DCE has an excellent cleaning effect and is environmental friendly but cannot be used alone because of huge safety hazard caused by its low flash point. 1-chloro-3,3,3-trifluoropropene (HCFO-1233zd) is used to inhibit the flash point of T-1,2-DCE. However, because the actual boiling points of these two substances are quite different, the two substances are easily separated at a slightly-high ambient temperature. Because a boiling point of HCFO-1233zd is extremely low, HCFO-1233zd will escape rapidly, resulting in the loss of inhibition on the flash point. In the present disclosure, T-1,2-DCE and 1-chloro-2,3,3-trifluoropropene are mixed to prepare a mixed solution, and the mixed solution can effectively maintain the inhibition on the flash point of T-1,2-DCE in various ambient temperatures, such that the T-1,2-DCE can be heated to generate a steam for cleaning.

Abstract: A preparation method of 1-chloro-2,3,3-trifluoropropene is provided. As a new eco-friendly compound that makes up a heat transfer medium, the 1-chloro-2,3,3-trifluoropropene (HCFO-1233yd) has been valued in the field of industrial cleaning and explosion-proof due to it excellent performance of low global warming potential (GWP) and ozone depletion potential (ODP) values, but HCFO-1233yd has high preparation cost that limits its large-scale application. In the preparation method of the present disclosure, 1,1,2,3,3-pentachloropropane is fluorinated into 1,2-dichloro-3,3-difluoropropene under the catalysis of a chromium-containing solid catalyst.
