The invention provides a vision tracking training early education toy with a built-in projection function, and relates to the technical field of vision tracking toys, the vision tracking training early education toy comprises a reciprocating motion toy, and the reciprocating motion toy comprises a shell serving as an integral framework to play a supporting and protecting role; the shell cover is detachably mounted at the port of the shell to close the shell and protect the interior of the shell; the projection part is arranged in the shell, can rotate along with the shell and keep the position unchanged, and can project different images; the eccentric module can adjust the overall gravity center position; the whole body can be driven by the moving part to transversely move; the inertia module can brake the moving part to be matched with the eccentric module to enable the whole body to turn over. The toy is driven by the moving part to integrally move in a transverse reciprocating mode, the toy is matched with the synergistic effect of the eccentric module and the inertia module to achieve the overturning action, diversified and non-monotonous movement tracks are formed, meanwhile, low-intensity natural sound generated along with the overturning action can continuously attract the attention of a baby, the baby is guided to actively follow the sight, and the safety of the baby is improved. And the visual tracking capability and the attention concentration degree are effectively exercised.

The present application relates to the field of cigarette technology, and particularly relates to a production method of a heat-not-burn cigarette and a cigarette. The production method of the heat-not-burn cigarette comprises the following steps: common tobacco shred production: mixing a tobacco powder mixture with a porous fiber base material to press a common tobacco sheet with a set thickness, and cutting the common tobacco sheet to obtain common tobacco shreds; heat-conducting tobacco shred production: attaching a heat-conducting metal material on the common tobacco sheet or attaching the heat-conducting metal material on the porous fiber base material to obtain a heat-conducting sheet, the surface density of the heat-conducting sheet being the same as that of the common tobacco sheet, and cutting the heat-conducting sheet to obtain heat-conducting tobacco shreds; and cigarette production: uniformly mixing the heat-conducting tobacco shreds and the common tobacco shreds with a set proportion, and rolling the heat-conducting tobacco shreds and the common tobacco shreds into cigarettes by using a cigarette rolling machine. The present application can improve the heat-conducting performance of the cigarette while not increasing the suction resistance, increase the release amount of smoke during smoking, and ensure the consistency of the product.

The invention relates to a hydrogen storage alloy composite material and a preparation method thereof.The preparation method comprises the following steps that S1, hydrogen storage alloy powder, an organic solvent and a coating layer raw material are in contact and subjected to ball milling treatment, and a first product is obtained; the coating layer raw material comprises a first metal source and a first organic ligand, or the coating layer raw material comprises an MOF material; and S2, optionally, carrying out roasting carbon deposition treatment on the first product. According to the preparation method provided by the invention, the air poisoning resistance of the hydrogen storage alloy material can be improved.
