The invention provides a method of measuring residual liquid hydrocarbon content in shale via low-field nuclear magnetic resonance. A shale sample of any shape is used to saturate manganese chloride solution of sufficient concentration; low-field nuclear magnetic resonance is then performed to obtain a nuclear magnetic T2 spectrum in the shale sample; the shale sample is subjected to dewatering prior to dealkylation; a T2 spectrum signal is measured again; amplitude integral difference delta S of the T2 spectral signal is introduced into a calibration relationship (namely, a marking equation)of hydrocarbon content and the signal, built in the method, so as to calculate hydrocarbon volume in shale of unit volume; the result is that the hydrocarbon volume in shale of unit volume is presented by percentage, which is considered as residual liquid hydrocarbon content in shale. The problems are effectively avoided that samples experience light hydrocarbon loss due to crushing pretreatment and that insufficiency of solvent polarity leads to incomplete extraction of heavy hydrocarbons; the method is suitable for precisely measuring residual hydrocarbon content in shale and is an effectiveand quick measuring method.

The invention provides an ultrasonic wave and microwave extraction system equipped with a reflux unit and used for traditional Chinese medicinal materials. The ultrasonic wave and microwave extraction system comprises a second reflux unit. The second reflux unit has a taper drainage cover which is inserted into a sample solution device; the large end surface of the taper drainage cover covers a whole liquid level and is located at a position which is above the liquid level and closest to the upper end of the sample solution device, so all the gas produced during microwave heating can enter the taper drainage cover and form liquid through condensation under the action of the inner wall of the taper drainage cover, and the formed liquid flows back to a sample solution along the taper drainage cover, thereby reducing air pressure above the sample solution device and improving an ultrasonic vibration effect.

The invention discloses a similarity measurement method based on learning, which includes: given the views of the stereo model, screening representative views to construct a view-based hypergraph to represent the relationship between the stereo objects; using the stereo model data, Spatial structure circular descriptors are extracted from each stereotype, and the distance between each stereotype is used to generate a simple model-based graph to explore the correlation between stereotypes; an appropriate learning framework is selected, and an initial The learning weight of , the hypergraph generated based on the view and the graph generated based on the stereo model are used as the input of the learning framework, and the optimal combination weight of the two graphs is learned through the joint learning framework, so that through the hypergraph based on the view and the graph generated based on the stereo model graph to estimate the correlation between stereo objects. The invention makes the description of the three-dimensional model more comprehensive and more accurate and scientific in the aspect of similarity quantification by extracting the view feature information and the three-dimensional model space structure information.

A method for identifying parts in the maintenance process of smart glasses. The invention belongs to the field of automobile maintenance. It is used to solve the technical problem in the prior art that the smart glasses data collection and touch operation position are not good. The technical points are: the mirror legs have a Revolving and bending, one side of the revolving and bending is connected to the first straight board, and the first straight board is provided with a touch pad facing the outside of the temple, and the other side of the revolving and bending is connected to the second straight board, and the second straight board is There are protruding bottom plates on both sides of the upper and lower sides, which form the accommodation part of the camera with the second straight plate. The second straight plate is provided with a camera mounting hole. The two bottom plates are connected with the optical machine, and the optical machine is located closer to it. In front of the lens frame, the lens frame is connected to the first straight plate and arranged near the turning and bending, and the first straight plate and the second straight plate are substantially perpendicular. The effect is: the data collection and touch operation positions of the smart glasses are better.
