简介：这篇论文集中于与一个帮助DP的绳索系统装备的一个半能沉入水中的平台的研究。基于帮助DP的绳索系统的工作原则和平台运动的模型，一个时间域模拟程序被使用分析影响在一线失败的情况中，在平台运动上，驱动推进器和系在的线的紧张的消费。结果显示出那，在10年的风下面主导，一线失败几乎没在系在的线的紧张上有很少影响。当失败线是上风的时，电源消费将与精确性的一个削弱的位置极大地增加。然而失败线是什么时候下风，电源消费将与精确性的一个部分加强的位置被减少。

简介：双相钢的基本成分为C和Mn，有时为了提高淬透性还添加一定量的Cr和Mo。DP钢是由低碳钢或低碳微合金钢经两相区热处理或控制轧制工艺而得到的一种高强度钢，包括热轧、冷轧、电镀和热镀锌产品。双相钢板钢的显微组织主要为铁素体和马氏体，热轧DP钢的生产通过控制冷却来得到铁素体和马氏体的组织，冷轧和热镀锌DP钢通过铁素体和奥氏体两相区退火和随后的快速冷却来得到铁素体和马氏体组织。

简介：AbstractJoint arthroplasty is an effective method for treating end-stage joint lesions and damages. Robotic arm-assisted arthroplasty, a rapidly developing technology that combines navigation technology, minimally invasive technology, and precise control technology of the robotic arm, can achieve accurate preoperative planning, optimal selection of implants, minimally invasive surgery, precise osteotomy, and accurate placement of the artificial joint. It has the characteristics of high accuracy and stability, and thus is more and more widely used in the field of joint surgery. In this paper, we systematically reviewed the application and clinical efficacy of robotic arm-assisted technology in hip and knee arthroplasty to provide reference for its future promotion.
