Abstract: The present disclosure discloses an optical measurement device and method for a plasma magnetic field with adjustable sensitivity. The method comprises the following steps: constructing an optical rotation measurement system based on a pulsed laser beam for measuring an optical rotation image and a shadow image; processing the optical rotation image and the shadow image, and obtaining a distribution of proportional coefficients based on alight intensity distribution; obtaining a distribution of rotation angles based on a mapping relationship between the proportional coefficients and the rotation angles; constructing an interference measurement system based on the pulsed laser beam, and measuring a phase shift of an interference image; calculating a distribution of electron areal densities based on the phase shift in the interference image; obtaining a two-dimensional distribution of an average magnetic field based on the rotation angles and the electron areal densities.

Abstract: The present disclosure provides a growth method of a high-temperature phase lanthanum borosilicate crystal, where the high-temperature phase lanthanum borosilicate crystal is a ?-La1-yLnyBSiO5 crystal prepared by a high-temperature flux method; a composite flux system is (La1-yLny)BO3—LiMoO4—SiO2—B2O3, and (La1-yLny)BO3, LiMoO4, SiO2, and B2O3 in the system have molar percentages of x1, x2, x3, and x4, respectively; 0<x1<0.3, 0.7?x2<1, 0<x3<0.3, x1+x2+x3=1, x1:x4=2:1 to 4:1. In the present disclosure, a difficulty is overcome in the crystal growth of ?-LaBSiO5 due to phase transition. The crystal is an optical function material that does not undergo the phase transition during annealing and can exist stably at room temperature. The crystal is widely used in laser, terahertz, and other fields.

Abstract: The present application discloses a monolithic catalyst with the function of selective adsorption-catalytic oxidation of organic waste gas and a preparation method and application thereof. The present application adopts a double coating design. A first coating is a molecular sieve primer coating. A second coating is an active component coating, which uses a neutral silica sol, so as to protect the activity and effectiveness of a noble metal and a catalytic promoter on the molecular sieve.

Abstract: Systems and methods for building and testing software projects within a virtual computing environment of a computing resource service provider, providing for gathering, reporting, and summarization of test results generated by test runs executed as part of the build process are disclosed. A user makes requests to a build service provided by the computing resource service provider which automates building and testing of program code for software modules and software projects including such modules. The build service receives the requests and allocates physical computing resources, such as usage of processors, memory, storage drives, computer network interfaces, and other components of hardware computing devices within a virtual computing environment to attempt to build the software modules and report results of tests performed during the build attempts. The user may supply program code to be built without otherwise needing to manage the virtual computing resources allocated to complete the requested tasks.
