Quantum mechanics is often considered as a relatively obscure physics course, which not only subverts beginners ' cognition for Newton ' s motion laws in classical mechanics but also makes learners afraid because of its complicated and profound mathematical theories in quantum mechanics. Thus, this article will, from the perspective of quantum mechanics, discuss the fundamental differences between the connotation of Hilbert space and spaces in classical mechanics. The application of Hilbert space in quantum mechanics will be expounded then. Finally, based on learners ' existing difficulties in learning process , several teaching suggestions will be presented for future teaching reference.

This paper takes wheat as the research object, and systematically studies the effects of drought stress on wheat physiological characteristics, yield and quality. By analyzing some physiological indicators, yield and quality of wheat Xinnong 106 variety under drought stress during the grain filling period, the influence mechanism of drought stress on wheat growth, development and output was explored. The results showed that drought stress has a significant effect on wheat physiological traits, root growth, grain filling characteristics and quality formation. On this basis, a regulatory strategy to alleviate the effects of drought stress on wheat yield and quality is proposed, which provides a theoretical basis for my country's wheat industry to cope with drought disasters.

With the development of the shipbuilding industry, the requirements for the safety and corrosion resistance of ship structural components are becoming increasingly high. Most of the components used in traditional ships are made of steel, which cannot meet the requirements of corrosion resistance and safety for existing ships. In order to improve the structural safety and corrosion resistance of ship railings, as well as their requirements for lightweighting, this article proposes a lightweight design for ship railing structures based on the existing T700 carbon fiber composite material railing structure. Carbon fiber composite materials have the advantages of light weight, high strength, and high modulus. Based on the anisotropy of carbon fiber composite fibers, the characteristics of overlapping/weaving structures, and the influence of the interface between carbon fiber composite materials and metal materials on the strength of ship railing structures, a finite element simulation model of carbon fiber composite materials is established. By setting constraints such as volume fraction, stress, strain, displacement, etc. based on the simulation model, the layout of materials in the optimization results is used to guide the design of the structure. The size parameters of the ship railing barrel are optimized, and the topology structure is optimized. Thus achieving lightweight design of ship railings and meeting the requirements for lightweight, safety, service life, and corrosion resistance of ship structural components.
