The application provides a molecular gas chamber leakage rate detection method, an electronic device and a detection system. The method can include: testing spectrum data of a to-be-detected molecular gas chamber; calculating a half-height width of the spectrum data according to the spectrum data; and determining a leakage rate of the to-be-detected molecular gas chamber based on the half-height widths obtained at multiple times. In the method, the leakage rate detection accuracy of the molecular gas chamber can be better ensured without affecting the purity in the molecular gas chamber.

A method for identifying positive cooperating effects in mixed insulating gases based on atomic charge distribution is proposed. This invention addresses the problem that current methods for determining the type of cooperating effects in mixed gases require experimental basis, resulting in high costs and time consumption. A stable structure is constructed for gas molecules A and B, and their interaction configurations. The wave functions of the two gas molecules and the wave functions of the interaction configurations are calculated in relation to the Boltzmann distribution ratio. The electronegativity of the two gas molecules is calculated based on their wave functions. The corresponding atomic charge distributions are calculated based on the wave functions of the three molecules in a neutral state. A linear weighted value of the charge transfer amount of each interaction configuration is calculated based on the Boltzmann distribution ratio. The charge transfer direction is analyzed based on the electronegativity of the two gas molecules and the linear weighted value of each interaction configuration. If the interaction configuration exhibits a characteristic of electron transfer to the less electronegative gas molecule, it is a positive cooperating effect; otherwise, it is a cooperating effect.

This invention relates to the field of catalyst preparation technology, and discloses a monolithic noble metal catalyst, its preparation method, and its application. The monolithic noble metal catalyst comprises a porous structured support and an active noble metal component and an auxiliary agent supported on the porous structured support. The particle size of the active noble metal component is 2-3 nm. The method includes: (1) sequentially acid-treating and calcining the structured support to obtain a porous structured support; (2) immersing the porous structured support in a mixed solution containing a noble metal precursor and optional structural auxiliary agent, and then sequentially subjecting it to high-pressure gas knife purging, drying, calcination, and reduction. The monolithic noble metal catalyst prepared by this invention exhibits good catalytic performance in the catalytic oxidation of carbon-based oxygen-containing molecular gases, and the catalyst exhibits significantly better stability, making it suitable for continuous long-term operation.
