The present invention provides a method for more easily producing a controlled-cluster-size noble-metal catalyst. This method comprises depositing a polynuclear complex comprising a plurality of organic polydentate ligands and a plurality of noble metal atoms on an oxide support, and then removing the organic polydentate ligands.

The invention discloses a measuring method of an outfield wave front aberration of a large-aperture space optical system, and belongs to the technical field of advanced optical system manufacturing. The measuring method aims at solving the problem that the existing detection means cannot meet a measuring requirement of the outfield wave front aberration of the large-aperture space optical system. The measuring method comprises the steps that 1, a measuring condition is initialized, a four-dimensional adjustment rack and a small-aperture parallel light generator are placed in appropriate positions at the front of a to-be-measured optical system, the small-aperture parallel light generator is turned to a specified viewing field by auxiliary equipment, x-direction and y-direction rotating devices are locked dead, an optical parameter of the to-be-measured optical system, an aperture of small-aperture parallel light and the number of subapertures required by measuring are input to a control computer, and the control computer generates an initial position and a motion locus of the small-aperture parallel light generator according to an initial parameter; 2, a wave front slope is measured; and 3, the wave front aberration is fit. A wave surface slop can be measured point by point in a time-sharing manner, and a large-aperture parallel light tube is not required, so that the difficulty of the outfield wave front aberration of the system is reduced.

The invention discloses a sulfonyl chloride compound taking carbazole as a fluorogen and a preparation method and applications thereof, and relates to the technical field of alcohol and amine substance detection in the fields of environment, medicine, food and sanitation.
