The invention discloses a parallel two-finger mechanical gripper which comprises a driver and two parallel clamping jaws paralleled mutually. The two clamping jaws are connected onto the driver; the driver is used for driving at least one clamping jaw to move; multiple elastic protruding parts are arranged on the opposite inner sides of the two clamping jaws in an array mode; and a cavity is formed in each elastic protruding part, so that the stressed elastic protruding parts can contract inwards when the two clamping jaws clamp an object. The invention further discloses a method for recognizing the types of grabbed objects through the parallel two-finger mechanical gripper. The parallel two-finger mechanical gripper provided by the invention has good stability and adaptability when being used for grabbing objects in different shapes.

An organic light emitting diode pixel arrangement structure and a display panel are provided. The organic light emitting diode pixel arrangement structure includes a central area and an edge area located around the central area. In the central area, four sub-pixels are arranged around a corresponding sub-pixel and have at least three different colors. A color of the corresponding sub-pixel is same as a color of one of the four sub-pixels arranged around the corresponding sub-pixel, so as to achieve high resolution display of the display panel.

The present invention relates to a method for separating and purifying natural product by using three-phase counter-current chromatography. Sad method is characterized by that in the immobile phase of conventional counter-current chromatography a solid separation medium-microsphere can be added so as to form a three-phase separation system including liquid immobile phase, solid immobile phase and liquid mobile phase, so that the counter-current chromatography and column chromatography can be combined into one body, therefore the separation and purification efficiency of natural product can be greatly raised.

The invention discloses a high resolution infrared imaging optical system. The system comprises a front optical system, a filter system, a microlens array, a back set optical system and a detector focal plane array which are sequentially arranged along an optical axis, wherein the microlens array is arranged on a back focal plane of the front optical system, the filter system is a flat lens provided with multiple shadow areas and transparent areas, the microlens array and the filter system are parallel, the microlens array comprises multiple microlenses which are spliced together, the detector focal plane array comprises multiple image elements which are spliced together, the image elements, the microlenses and the transparent areas correspond to each other in one-to-one mode, and a modulation system is further arranged between the optical system and the filter system. The invention further discloses an imaging method. The system is advantaged in that the structure is simple, the system is easy to process, high resolution infrared imaging can be realized without any motion part, super large aperture angles can be realized, the system is particularly suitable for infrared wave bands, and a problem of low resolution of an infrared imaging system in the prior art can be effectively solved.

The invention discloses a high-resolution detection and identification method for debonding defects of composite materials. Under the action of a light-excited infrared thermal imaging system, a sample containing defects has different thermal diffusion and thermal radiation characteristics in different regions of the material. There is a high-temperature area at the defect, and the surface temperature field collected by the thermal imager can reflect certain defect information with time and space, and provide information for the later feature extraction algorithm, and then based on the integrated variational Bayesian tensor decomposition algorithm Extracting information on debonding defects in composite materials.
