The invention discloses a device and a method for testing a non-uniform pressure field of a viscous medium during pressure forming, and relates to a test device and a test method. The invention aims to solve the problems that the existing method and device cannot easily test deformation behaviors of instability wrinkling and wrinkle elimination under the action of various non-uniform velocity fields and pressure fields during necking of a large-diameter-ratio thin-wall or ultrathin-wall pipe, and each mold device can only test the influence of one loading mode on the non-uniform pressure field on the surface of a cylinder blank each time. The device disclosed by the invention is reasonable in structural design and is comprehensive and accurate in test data. The test method comprises the following steps: injecting the viscous medium by multiple pistons at different speeds; measuring the injection pressure in real time by virtue of a pressure sensor; and controlling the injection pressure of the viscous medium by virtue of reciprocating of the pistons to form multiple non-uniform pressure fields and velocity fields in a medium cabin so as to ensure that a pipe blank is subjected to necking deformation under different conditions. The device and the method disclosed by the invention are used for researching the influence of a loading mode of the viscous medium on pressure diameter reduction of a pipe blank viscous medium.

The present invention relates to marine biology, paleoceanography, sedimentary geology and other disciplines, and can be applied in the fields of foraminifer species identification research, marine environment indication research, paleoenvironment reconstruction and global change research, etc. Specifically, it is a A rapid preparation method for deep-sea foraminifera lumen structure grinding plate. Foraminifera isolated from deep-sea sediments were treated with gum immersion, hanging drop embedding, position adjustment and water grinding, that is, complete grinding of the inner cavity structure of deep-sea foraminifera was quickly obtained. The invention can more accurately identify the species of the foraminifera through the level information obtained by grinding, and avoid scientific confusion such as identification errors caused by external morphological variations such as the shape, texture, and number of chambers of the foraminifera. The invention provides accurate scientific basis and quick problem-solving scheme for the accurate identification of types of deep-sea foraminifera and the research on indications to the marine environment, paleoenvironment reconstruction research, global change research and other subject fields.
