When air is supplied by an air pressure regulation part to bellows 211 through 213 of finger joint motion facilitation parts 110j (where j=1, . . . , 5), the bellows 211 through 213 expand approximately in the shape of circular arcs, since annular grooves on the side of the bellows 211 through 213 opposing a joint are elastically restrained by elastic members 241 through 243. Due to this, the bellows 211 through 213 cooperate, and exert force in the rotational direction to flex the first through the third joints of a finger from their extended states. Next, when air is exhausted from the bellows by the air pressure regulation part, the bellows 211 through 213 contract. Due to this, the bellows 211 through 213 cooperate, and exert force in the rotational direction to extend the first through the third joints of a finger from their flexed states. The forces generated in this manner are transmitted to the joints by transmission members 231 through 234. As a result mounting becomes simple, and also it is possible to facilitate sufficient joint movement for each joint.

The invention discloses a layered gradient porous material sweating cooling structure and an aircraft. The sweating cooling structure comprises N layers of porous material layers and a cooling cavity arranged on one side of the porous material layer. A coolant supply unit is arranged in the cooling cavity , the coolant supply unit is used to supply coolant to the cooling cavity, the porosity of the porous material layer decreases layer by layer along the direction close to the cooling cavity, wherein, N is an integer, N≥2. The invention solves the problems of uneven heat dissipation, poor heat protection effect, high cost and the like existing in the sweating cooling structure in the prior art.

The invention discloses a steam box and a method of adjusting temperature and humidity of paper. A preheating chamber is arranged outside the steam box; the preheating chamber is connected to an upstream pipeline of a steam manifold through a preheating branch pipe; the steam box comprises a constant current region and a regulation region along an advance direction of the paper in sequence, and a perforated plate is arranged at the bottoms of the constant current region and the regulation region; a downstream pipeline of the stream manifold is divided into a branch pipe of the constant current region and a branch pipe of the regulation region; the constant current region is an independent constant current chamber, and the constant current chamber is communicated with the branch pipe of the constant current region through a constant current branch pipe; the regulation region is divided into a plurality of independent regulation chambers through partition boards and is communicated with the branch pipe of the regulation region through a regulation branch pipe; the constant current region and the regulation region are combined, the caliber of the branch pipe of the constant current region is greater than the caliber of the branch pipe of the regulation region, the stream flow of the regulation region is small, so that the size of a branch pipe control valve is reduced; the length of the regulation region is greater than that of the constant current region so as to be beneficial for full action of the steam and the paper, thereby increasing the utilization efficiency of the stream; the stream overflow is reduced, and the environment of manufacturing the paper with pulp is preferably protected.

The invention discloses a magnetic nano-microsphere with a shell-core structure and a method for extracting clenbuterol from mutton, wherein the magnetic nano-microsphere is Fe 3 o 4 @C@Co 3 o 4 , the present invention is based on the magnetic solid-phase extraction technology, using the magnetic nano-microspheres as the adsorbent to extract the clenbuterol in the mutton, and realizes the selective enrichment of the clenbuterol in the mutton sample to be tested, It can significantly improve the sensitivity of high performance liquid chromatography (equipped with ultraviolet detector) to detect clenbuterol in mutton.
