Abstract: Disclosed is a rotational flow rotation deoiling method for oil-based mud rock debris. The method comprises the following steps: (1) System viscosity control, wherein by means of heat exchange between a gas medium and the rock debris, the viscosity of the oil-based mud debris is reduced to reduce the interaction force between oil, water, and the surface and channels of solid particles, thereby facilitating the separation in a rotational flow field; (2) Rotational flow rotation deoiling, wherein the oil-based mud rock debris particles undergo a coupled motion of rotation and revolution, wherein by means of the rotation of the rock debris particles, the centrifugal desorption of oil on the surface of a solid phase, oil in capillaries and oil in pores is enhanced; and by means of the centrifugal force of periodic oscillation generated by the revolution thereof, the separation and enrichment of oil and gas and the solid phase are completed, thereby achieving the removal of the oil phase from the pore channels of the rock debris; and (3) gas-liquid separation and reuse, wherein an oil-containing mixture produced in step (2) is subjected to gas-liquid separation so as to realize the reuse of a base oil, circulation of the gas medium, and a harmless treatment of the rock debris; and a rotational flow rotation deoiling device for oil-based mud rock debris is further comprised.

Abstract: The present disclosure provides a machine vision-based automatic focusing and automatic centering method and system, which belongs to the technical field of machine vision-based automatic control. An object stage is controlled to move in an imaging distance range of an electron microscope, and images scanned by the electron microscope when the object stage is at different imaging distances are acquired. The image definition of an object stage image is calculated according to a gray-scale value of each pixel in the object stage image, the imaging position when an image definition value is the maximum is determined, and the object stage is controlled to move to the position, so as to realize machine vision-based accurate focusing. After the accurate focusing is completed, the images that can clearly reflect the arrangement relationship between an indenter and a sample on the object stage are acquired by the electron microscope, and a midline of an indenter area and a midline of a sample area are aligned, so as to realize machine vision-based accurate centering, which avoids the problems of low efficiency and poor accuracy in manual focusing and centering, and improves the focusing and centering efficiency.

Abstract: Disclosed is a method for efficiently synthesizing primary amines, which comprises using carbonyl compounds or alcohol compounds as reaction substrate, liquid ammonia or alcohol solutions of ammonia as nitrogen source, and hydrogen as hydrogen source, and reacting in reaction medium catalyzed by a cobalt-based catalyst to obtain the primary amines. Due to high catalytic activity, the method can realize the reductive amination of carbonyl compounds and the hydrogen-borrowing amination of alcohol compounds at low temperatures in a short time to obtain the primary amines with high yield, and is applicable to a wide range of substrates. The obtained primary amines can be used as raw materials with high extra value for producing polymers, medicines, dyes and surfactants. Further, the cobalt-based catalyst has a good industrial application prospect because it is magnetic which can facilitate separation and recycling of the catalyst. Moreover, the inexpensive cobalt-based catalyst can significantly reduce industrialization cost.
