Abstract: The present disclosure provides a quantitative accuracy evaluation method and system for a result of remote sensing inversion. The method includes the following steps: acquiring measured data of a target element content in a preset zone; acquiring, based on acquired remote sensing image reflectivity of the preset zone, predicted data of the target element content in the preset zone by a remote sensing inversion model; and conducting comprehensive index evaluation of abnormal feature similarity between the measured data and the predicted data. The technical solution adopted in the present disclosure can solve the problem with quantitative accuracy evaluation of remote sensing inversion that inverted object content and measured object content are distributed inconsistently in space.

Abstract: A safety lid is provided for an electric pressure cooker. The electric pressure cooker comprises a housing, an outer pot received in the housing, and an inner pot removably disposed within the outer pot. The safety lid includes a lid body for covering the inner pot, an inner rim extending from the lid body for lockably engaging with an upper rim of the outer pot, and an outer rim extending from the lid body and being substantially concentric with the inner rim. The inner rim and the outer rim of the safety lid are spaced apart to define an annular groove for receiving an upper rim of the housing. An electric pressure-cooking appliance equipped with the safety lid is also provided.

Abstract: Provided herein is a method of hot gas forming and heat treatment for a Ti2AlNb-based alloy hollow thin-walled component, which pertains to the technical field of plastic forming manufacture of thin-walled components made from difficult-to-deformation materials, more particularly, a forming method of Ti2AlNb-based alloy hollow thin-walled components is involved. The purpose of this invention is to solve the existing problems that Ti2AlNb-based alloy hollow thin-walled components are difficult to form, process steps are complex, and the shape and dimension precision is in contradiction with the control of the microstructure and properties. The method comprises the following steps: (1) hot gas forming to obtain hot gas formed tube components, and (2) controllable-cooling heat treatment to obtain Ti2AlNb-based alloy hollow thin-walled components.

Abstract: Provided is a near-infrared light absorbing glass with a near-infrared light absorbing element and a near-infrared light absorbing filter. When the length of the near-infrared light absorbing glass is 1 mm, transmissivity is more than 80% at the wavelength of 400 nm, and more than 85% at the wavelength of 500 nm. The near-infrared light absorbing glass contains P5+, Al3+, Li+, R2+ and Cu2+ represented by positive ions, wherein R2+ represents Mg2+, Ca2+, Sr2+ and Ba2+. Meanwhile, the near-infrared light absorbing glass contains O2? and F? represented by negative ions. Water durability (DW) of the near-infrared light absorbing glass reaches Class 1 and acid durability (DA) reaches above Class 4. In this invention, fluorphosphate glass is used as the matrix glass and the components are designed specially, so that the melting temperature of glass can be effectively lowered and the chemical stability of the glass can be excellent.

Abstract: In one example, we describe a type of plasma-enhanced atomic layer deposition equipment including: fluidly connected plasma generation chamber, diffusion chamber, reaction chamber, and pumping chamber, wherein the plasma generation chamber includes a plasma generation gas inlet and a plasma generation device that enables the generation of plasma from the plasma generation gas coming from the plasma generation gas inlet. A precursor inlet is disposed between the plasma generation chamber and the diffusion chamber. Precursors coming from the precursor inlet and generated plasma diffuse uniformly inside the diffusion chamber. A sample stage, for the placement of sample to be deposited on, is disposed inside the reaction chamber. The pumping chamber is sequentially connected to an exhaust trap and pumping system. The equipment has enabled high quality atomic layer thin film deposition.
