Abstract: The present disclosure relates to a coaxial four-reflection optical system with visible light long-wave infrared common-aperture imaging, and belongs to the technical field of optical systems. The technical problems that the axial length compactness and the imaging quality of the visible light/infrared composite imaging system in the existing technology need to be improved are solved. The optical system of the present disclosure includes a main reflecting mirror, a first transmitting mirror, a third reflecting mirror, a fourth reflecting mirror, a second transmitting mirror, a third transmitting mirror and a fourth transmitting mirror.

Abstract: An atomizer includes a liquid storage assembly, an atomizing assembly and a base assembly; the base assembly is detachably connected to one end of the liquid storage assembly, the atomizing assembly is arranged between the base assembly and the liquid storage assembly, the liquid storage assembly includes an elastic member, the elastic member is elastically biased between the liquid storage assembly and the atomizing assembly, and when the base assembly is detached from the liquid storage assembly, the atomizing assembly is ejected out by the elastic member. The atomizer is convenient for a user to take out the atomizing assembly. An aerosol generating device using the atomizer is further provided.

Abstract: The present invention provides a virulent Pseudomonas fluorescens (P. fluorescens) phage ?Pf1901, and a phage ?Pf1901 preparation and an application thereof, and relates to the technical field of phage. The virulent P. fluorescens phage ?Pf1901 has an accession number of CCTCC M2019447. The virulent phage ?Pf1901 has a titer of (1.4-3)×1010 PFU/mL. The virulent phage ?Pf1901 has an optimal multiplicity of infection (MOI) value of 0.0001. The virulent P. fluorescens phage ?Pf1901 provided by the present invention exhibits very high specificity and lytic ability to P. fluorescens, which can be used to control P. fluorescens, with strong lytic and scavenging effects on a host.

Abstract: A battery assembly and an electronic cigarette are provided. The battery assembly includes a housing, a first cover provided with a first mounting column, and an electronic switch received in the first cover. The first cover defines a first mounting slot corresponding to the electronic switch. The first cover is mounted on the housing by the cooperation of the first mounting column and the first mounting slot, pressing the outside wall of the first cover causes the first mounting column to press the electronic switch and turn on the electronic switch. The structure of the battery assembly is simple, the processing operation becomes easy, and the manufacturing cost is low.

Abstract: Described is a printing method comprising: forming an organic material layer on a non-printing region of a substrate, the burning point of the organic material layer being lower than the pre-curing temperature of glass glue; performing printing processing on the substrate so as to form the glass glue on a printing region of the substrate; and performing a burning processing of the organic material layer so as to separate the organic material layer from the substrate. Such a printing method can effectively avoid the occurrence of the printing offset and burrs and thus greatly reduce the rate of defective goods.

Abstract: In one embodiment of a method of printing in a network, a connection is established from a user equipment to a printing system. A secure connection is established between the user equipment and a server. From the user equipment, a file on the server is selected. From the user equipment, information indicating the file and information indicating a path from the printing system to the server via the user equipment is passed to the printing system. The printing system is caused to retrieve the file from the server via the path. The printing system is caused to print information contained in the file.

Abstract: A structure for coupling together addressably disparate nodes, such as IPv4 nodes and IPv6 nodes, without the use of an application level gateway. Instead, the system includes two executable applications, HEART and ECHO, that avoid the necessity of an application level gateway. In general, HEART and ECHO cooperate with each other through a network address translator-protocol translator (NAT-PT) to cause the NAT-PT to temporarily assign an IPv4 address to a control session between the IPv4 and IPv6 nodes and also prevent the control session from timing out due to lack of timely communications between the IPv4 and IPv6 nodes.
