Abstract: Disclosed is a data analysis-based intelligent deformation monitoring system for mountain landslides, which solves the technical problem in the prior art that when a landslide occurs in a landslide area, it is not possible to implement region-specific monitoring for landslide soil, thus failing to minimize the real-time impact of the landslide area. The present disclosure involves marking a sub-area where a landslide occurs as a landslide area, marking a real-time sliding direction within the landslide area as a landslide flow direction, setting areas at both sides of the landslide flow direction as landslide slopes, generating a control adjustment signal or a risk monitoring signal through landslide slope analysis, and sending the signal to a server.

Abstract: Described herein is a supported organotin catalyst and a preparation method for a sucrose-6-carboxylate. The supported organotin catalyst is prepared by coupling an organotin functional group to an inorganic carrier. The supported organotin catalyst of the present application can be used for catalyzing the generation of a sucrose-6-carboxylate, and after reaction, the supported organotin catalyst can be directly filtered and recovered only by adding a small amount of water to quench an acylating agent, so that the subsequent dehydration process is simpler and easier, and the supported organotin catalyst is thus very economical in terms of manpower, equipment and energy.
