Problems solved by technology

However, this technology has the following disadvantages: this technology is to first record the sample under the microscope, and then put it into different sulfuric acid solutions to soak and corrode. The recording is carried out intermittently; the experimental process of this technology is relatively cumbersome, and at the same time it is difficult to determine the image pickup position at different time periods of the test, and the positioning is prone to deviation; and this technology cannot realize the collection and measurement of ions in the mixed solution after corrosion
However, this technology has the following disadvantages: this technology uses stone as the research object of artificial corrosion, not for dinosaur fossils; this technology first uses the image of the stone surface before corrosion under a microscope, and soaks it in a simulated solution with low ion concentration for 10 cycles The finished stones are air-dried in a clean room, and then use a scanning electron microscope (SEM) to obtain surface images of the stones corroded by acid rain. Therefore, the images are captured in gaps and are discontinuous. At the same time, there are inaccurate positioning and misalignment of calcium ions. Changes in the pitfalls of qualitative analysis
However, this technology has the following shortcomings: this technology uses stone as the research object of artificial corrosion, rather than dinosaur bone fossils, and there are differences between the corrosion objects; when the stone is leached and cyclically corroded, the pH value increases with the corrosion cycle time If it increases, the consistency of pH value cannot be maintained; the qualitative analysis of calcium ions is not carried out under the same pH value conditions, and it is impossible to grasp the changing law of calcium ions in the continuous corrosion of dinosaur bone fossils at the same pH value

Description

technical field [0001] The invention belongs to the technical field of fossil corrosion, in particular to a system and method for simulating the acid rain corrosion process of dinosaur fossils. Background technique [0002] Dinosaurs are the most successful and largest terrestrial animals in the history of the earth. They once ruled the earth for 160 million years, but their sudden extinction at the end of the Cretaceous period 65 million years ago left a An unsolved mystery through the ages. Dinosaur fossils are an important physical basis for human beings to understand the mysteries of dinosaurs. They are of great scientific value for the changes in the earth's history and the evolution of reptiles during the Mesozoic Era, as well as for the study of paleogeography, paleoclimate, and paleoecology. China is the country with the richest resources of dinosaur fossils in the world. Rich dinosaur fossils have been found in more than 20 provinces (municipalities and autonomous ...
