摘要:改进的source-path-receiver模型的开发是用来参数化验证滑动摩擦结构对齿轮噪声的影响。假设由于刚性轴承阻抗不匹配，源子系统的直齿轮副的承载力预测界面在线性运动和非线性运...

Abstract ：In this work, we examine port crane scheduling with spatial and separation constraints. Although common to most port operations, these constraints have not been previously studied. We assume that cranes cannot cross, there is a...

摘要：涂层的残余应力状态的影响刀具寿命和加工性能。由于在切割过程中形变场负荷涂料需要定制属性。旁边的涂料结构最重要的两个属性是残余应力状态和涂层的化学成分。因此...

摘要本论文提出设计永磁交流发电机（协会）的有限元分析（FEA）的方法。协会管理公司被配置为一个由两个相同的悬臂空心滚动接触支撑轴承。协会管理公司的性能要求是16000rpm的最大...

Discuss the construction temperature and crack of the concrete ABSTRACT In order to prevent the owners of the concrete work of claims, we must do a good job in the construction process in the temperature and crack control,through observatio...

Abstract The design of progressive dies is a very knowledge-intensive, complex, and time-consuming process. This paper describes a computer-aided structural design system for pro-gressive dies with drawing, bending, and punching operations....

斑马鱼lmo4b基因在斑马鱼胚胎发育的早期分节时期作为一个前脑发育的负调控器通过限制six3与rx3的表达来发挥作用。利用玛琳（morphlino）的抑制作用造成lmo4b减少导致胚胎前脑和眼睛囊泡...

实验室现代的实验室需要可调控温度、湿度、相应气压、空气流动、空气净化、声音以及排气。这一章我们讲到了生物、化学、动物以及物理因素。在这些分类当中，一些实验室有独特...

1. Introduction Injection molding is the most popular method for producing plastic products because of its high productivity and the manufacturability for making various complex shapes. The injection molding process includes six stages: mold...

Abstract: Effect of material change of plastic product is investigated in this research paper. The parameter observed are waste recycle, impact property of product, aesthetic look, cycle time, production rate and cost of product. In this stu...
