The invention relates to a furosemide tablet and a preparation method thereof.The furosemide tablet is prepared from, by weight, 25.00% of furosemide, 40%-45% of filler, 27%-33% of adhesive, 0.5%-1.5% of lubricant, 1.0%-2.0% of anti-sticking agent and 0.5%-1.5% of flow agent.The furosemide tablet is prepared by adopting the technology that purified water is directly added without preparing the adhesive; a wet granulation process is adopted, the controllability of process parameters in the production process is high, the human influence of operation of multiple process steps is reduced, the quality stability of the medicine is effectively improved, the quality of the medicine is equivalent to that of a commercially available reference preparation, and multiple dissolution curves are similar to that of the reference preparation; the in-vitro dissolution behavior similar to that of a reference preparation is shown, the quality is stable, and the dissolution behaviors among batches are consistent.

The utility model relates to the technical field of physical experiment teaching aids, in particular to a simple harmonic motion experiment instrument, which comprises a base, a liquid spraying device, a support arranged on the base and a paper feeding device arranged on the base, the support comprises a cross rod, a first vertical rod and a second vertical rod, the first vertical rod and the second vertical rod are arranged on two opposite sides of the cross rod, and the cross rod is provided with a cycloid and connected with a pendulum ball. A gap exists between the lowest point of the swing ball in the natural state and the base, a spring is fixed to the first vertical rod and is horizontally placed in the natural state, one end of the spring is detachably connected with the swing ball, the liquid spraying device comprises a spraying pipe, and the liquid outlet end of the spraying pipe is fixedly connected with the swing ball; a spring oscillator experiment and a simple pendulum experiment are integrated on one device, so that students can conveniently compare two simple harmonic motion phenomena on the same platform, the essence and generality of the simple harmonic motion can be deeply understood, and the teaching effect is optimized. Meanwhile, through the detachable connection design, quick switching between a spring oscillator experiment and a simple pendulum experiment is facilitated, and different experiment requirements are met.
