This invention discloses a dual-piezoelectric tube driven inertial motor and its control method, along with a scanning probe microscope, relating to the field of piezoelectric tube technology. The invention includes a base, a first piezoelectric tube, a second piezoelectric tube, and a U-shaped sliding body. The first and second piezoelectric tubes are parallel to each other along their axes, with one end fixed to the base and the other end free.

Through the detachable structure (the cover plate, the sealing ring and the fixed knob), parts are convenient to clean or replace, and the user experience is improved; the rotation function of the fixed knob allows adjustment of sealing pressure to adapt to different pot opening states (such as thermal expansion and cold contraction), and excessive compression or failure of the sealing ring is avoided.

A feeder for reducing the pressure of grain on a grain dispensing system includes a grain storage device for holding grain, a grain outlet for grain outflow, and a grain dispensing system disposed within the grain storage device to intermittently guide grain into the outlet. A grain retainer is also disposed within the grain storage device, shielding the grain dispensing system, and the orthographic projection of the retainer towards the grain dispensing system covers the system. At least one leakage port is provided on the retainer for grain to leak out towards the grain dispensing system. This technical solution reduces the resistance of the grain within the grain storage device to the grain dispensing system when the system is activated, effectively protecting the normal operation of the grain dispensing system and extending its service life.

A negative Poisson's ratio composite explosion-proof material and its preparation method are disclosed. The material comprises a gradient chiral superstructure shape memory alloy skeleton reinforcement phase, a shear-thickening liquid filler, and a ceramic particle reinforcement phase. The shape memory alloy skeleton reinforcement phase is formed by horizontally arranging and axially stretching gradient structure negative Poisson's ratio cell units. The negative Poisson's ratio cell units are composed of a gradient array of four-ligament or six-ligament chiral honeycomb structures. A mixture of the shear-thickening liquid filler and the ceramic particle reinforcement phase is impregnated and filled into the shape memory alloy skeleton. After solidification, the negative Poisson's ratio composite explosion-proof material is formed. The volume percentage of the shape memory alloy skeleton reinforcement phase is 20%–60%, the volume percentage of the shear-thickening liquid filler is 20%–40%, and the volume percentage of the ceramic particle reinforcement phase is 10%–50%. The preparation method of this invention is scientifically sound and reasonable. The composite explosion-proof material exhibits low density, high impact strength, high fracture resistance, and good energy absorption and shock absorption properties, showing broad application prospects in explosion-proof, bulletproof, and lightweight armor protection.
