The invention relates to a high-resolution spectral imaging device for monitoring atmospheric greenhouse gas, which is suitable for visible to infrared spectral imaging and consists of a wide-view-field small front-end system and a spectral imager. Incident light passes through the entrance slit, the optical filter and the first lens after passing through the front-end system, irradiates the off-axis concave reflector and is reflected to the plane grating, and the light dispersed after passing through the grating is close to a Littrow state and irradiates back to the off-axis concave reflector, so that a dispersed spectrum is converged to irradiate the mirror and passes through the second lens, and the spectrum is further focused to the detector. According to the invention, the problems of small detection breadth and low time resolution of an atmospheric greenhouse gas monitoring system in the prior art are solved. The invention has the advantages of large field of view, high spatial resolution (2km), high spectral resolution (0.05 nm-760nm), high time resolution (one day), compact structure and small volume, and can be applied to the field of aerospace remote sensing.

The application discloses a defoaming device of falling film evaporator, which comprises a shell, the shell is provided with a steam inlet at the bottom and a steam outlet at the top, at least one vertical defoaming channel and a steam guiding mechanism are arranged in the shell, the defoaming channel is provided with an input port connected with the steam inlet and an output port connected with the steam outlet, the steam guiding mechanism is used for guiding steam to flow into the input port of the defoaming channel, and the width of the defoaming channel gradually decreases along the guiding direction of the steam guiding mechanism. The application has the beneficial effects of improving the defoaming effect and efficiency.

The invention discloses a preparation method of lead-free metallic luster glaze, which is characterized in that a formula system is constructed by introducing lead-free raw materials such as calcium borate frits and recycling steel slag, and coloring ions (Co < 2 + >, Fe < 3 + >, Mn < 2 + > and the like) are promoted to be uniformly distributed in a network structure, so that a glaze layer is endowed with the characteristics of environmental protection, high glossiness and stable color. The production cost is effectively reduced, the remarkable problems of the traditional lead-containing glaze in the aspects of environmental protection and safety are effectively solved, and the lead-containing glaze can be widely applied to the fields of art, daily use and architectural ceramics.
