Abstract: Disclosed is a multi-dimensional optical tweezers calibration device based on electric field quantity calibration and a method thereof. The polarization-dependent characteristics of a tightly focused optical trap are utilized to realize triaxial electric field force calibration of particles through a one-dimensional electric field quantity calibration device. The method of the present application enables a particle electric field force calibration system to be compatible with particle delivery and particle detection systems; the device is simplified and calibration complexity is reduced.

Abstract: A hinged structure of a vegetable cutter comprises a vegetable cutter body and a vegetable cutting pressing plate; the vegetable cutter body is provided with a vegetable cutting knife frame, the vegetable cutting pressing plate is provided with a material pressing plate, and the material pressing plate is capable of pressing a material on the vegetable cutting knife frame. The hinged structure of the vegetable cutter is characterized in that: a detachably connected hinged portion is arranged between the vegetable cutter body and the vegetable cutting pressing plate, the hinged portion comprises a hinged shaft and a limiting device for limiting the hinged shaft, and rotary connection between the vegetable cutter body and the vegetable cutting pressing plate is realized through the hinged shaft and the limiting device, so that a structure is simple, and a user disassembles and assembles the vegetable cutting pressing plate conveniently.

Abstract: The present invention discloses an automatic potato-cutting machine, which includes a casing, a base and a push plate. The casing is arranged on the top of the base, a first installation groove is on one side of the casing, and a first buckle is arranged on one side of the first installation buckle. A shielding structure is arranged on the top of the side plate. In the present invention, a blade is movably connected inside the installation housing, and the blade and the installation housing form a snap-fit structure, so that the blade can be snapped into the inside of the installation housing, and then the first installation buckle can slide inside the first installation groove, the sliding of the first installation buckle can drive the first buckle to move, and the movement of the first buckle can be snapped into the slot on the blade.

Abstract: A process for producing light olefins from inferior oils includes the steps of: subjecting an inferior oil to a thermal conversion reaction in the presence of hydrogen to obtain a conversion product; separating the conversion product to obtain a first separated product; separating the first separated product to obtain an upgraded oil and a pitch; subjecting the upgraded oil to hydro-upgrading to obtain a hydro-upgraded oil; separating the hydro-upgraded oil to obtain a hydro-upgraded heavy oil; and subjecting the hydro-upgraded heavy oil to catalytic cracking to obtain a catalytic cracking product comprising a light olefin.
