说明：  三轴代码颗粒流问题是众多工农业生产领域中的常见问题，然而人 们至今对颗粒流机理认识不深。目前一种基于离散元的数值模拟方 法被用以模拟和分析颗粒流问题，研究实践表明该方法是散体力学 分析的一种有效的工具，PFC 3d离散单元法在岩土工程真三轴中使用广泛。(Particle flow is a common problem in many fields of industrial and agricultural production Up to now, the mechanism of particle flow is not well understood. A numerical simulation method based on discrete element The method is used to simulate and analyze particle flow problems. The research practice shows that the method is granular mechanics PFC 3D discrete element method is an effective tool for analysis, which is widely used in true triaxial analysis of geotechnical engineering.)

些被所有设计师认可的简单装配技术如卡扣装配、压机装配和螺纹装配等，以其简便、快速地装配组件可大大地节约生产成本。 -some designers recognized by all the simple assembly technologies such as Buckle assembly, press and assembly screw assembly. its simple, rapid assembly components can greatly reduce production costs.
