In addition, a protective plate is installed at the top end of the supporting plate, additional protection is provided for the driving motor and the connecting rod, and therefore the practicability of the equipment is enhanced.

This invention relates to a CVD-modified coating, its preparation method, and its application, belonging to the field of coating technology. The preparation method includes the following steps: obtaining a CVD coating using chemical vapor deposition; subjecting the CVD coating to freeze-drying to obtain a first CVD coating; subjecting the first CVD coating to magnetic field heat treatment to obtain a second CVD coating; and sequentially alternatingly processing the second CVD coating with the freeze-drying and magnetic field heat treatments to obtain the CVD-modified coating. Based on existing CVD coating preparation methods, this invention utilizes a combined magnetic field heat treatment and freeze-drying process for synergistic modification, optimizing the microstructure of the CVD coating. When applied to a substrate surface, it can improve its hardness and wear resistance, thereby extending the service life of devices such as cutting tools, molds, and machine parts, and has a wide range of applications.

The invention relates to a maltose-based bacillus subtilis self-induced gene expression system and application thereof, and belongs to the field of gene engineering. An induction system commonly used in bacillus subtilis has the problems that exogenous addition is needed, operation is tedious, cost is high, expression intensity is low and the like, and efficient expression and industrialization of protein and metabolites are not facilitated. According to the invention, site-directed mutagenesis is carried out on a PmalA promoter to obtain a high-performance promoter PmalA1, and a T7 RNA polymerase amplification module is further combined to construct a PT7malA1 expression system. The system can automatically start expression after glucose is used up without adding an inducer, and has the advantages of simple and convenient induction process, low leakage, high expression intensity, capability of accurately controlling the induction time by regulating the glucose concentration and the like. By applying the system, efficient synthesis of lycopene and beta-carotene is successfully realized, the yield is remarkably increased, and excellent industrial application potential is shown.

This invention discloses a method for improving the induction rate of prothallus and sporophyte in *Cibotium barometz*, comprising: S1, sterilizing the substrate with a fungicide, wherein the fungicide includes thiophanate-methyl and tebuconazole, and after sterilization, reducing the substrate moisture content to 40-50%, obtaining a sterilized substrate; S2, contacting the bottom of the substrate with a hormone aqueous solution, obtaining a substrate absorbent with the hormone aqueous solution; S3, sowing *Cibotium barometz* spores on the substrate surface for cultivation. This invention shortens the spore germination time of *Cibotium barometz*, improves the induction rate of prothallus and sporophyte, and is simple and easy to implement. Using this method to cultivate *Cibotium barometz* seedlings, prothallus are induced in an average of 22 days, and sporophyte are induced in 66 days. This method can be applied on a large scale to the sowing and seedling cultivation of *Cibotium barometz*, saving seedling time and labor costs.
