摘要：采用正弦扫描动态测试方法,研究双瓦楞纸板与薄EPS板材(23mm厚)组合试样在防振缓冲包装应用中的振动传递特性。测试在不同静应力下的频率响应曲线,探讨其固有频率和振动传递率与静应力之间的关系,所得数据对指导家电产品包装设计有一定实际意义。

摘要：通过对猪、绵羊CD58mRNA序列比对,设计出绵羊CD58的特异性引物,应用反转录PCR技术从绵羊淋巴细胞mRNA中扩增出绵羊CD58基因,将该基因克隆到原核表达载体pGEX4-1中进行原核表达.结果表明:克隆出的绵羊CD58cDNA长807bp,其中包含了开放式阅读框;该基因在大肠杆菌中进行表达,SDS-PAGE电泳在53ku处能观察到特异表达的融合蛋白,产物通过Western-blot检测证实,可以被CD58单克隆抗体识别.

摘要：当前市场中的传统烘干设备与叠衣辅助工具普遍面临功能局限性大、实用性不足的问题,不能广泛普及市场及家庭。鉴于此,设计一款集烘干、消毒和折叠功能于一体的机器,机器采用Arduino为控制器,主体框架由铝型材构建,配合直流电机、舵机及传感器共同驱动设备高效运作。设备通过底部的加热系统实现衣物的烘干,并内置温湿度传感器监测烘干过程,确保衣物干燥;通过紫外线灯管杀灭衣物上的细菌与病毒。折叠环节采用同步带轮机制,驱动衣架进行独立而精准的运动,实现衣物的自动识别与智能折叠。此设计旨在解放人力,用户可享受从烘干、消毒到自动折叠的一站式服务,节省时间的同时减轻了用户的日常负担。凭借其高效、卫生、健康及便捷的特性,设备可广泛部署于医院、工厂等场所,推动相关领域向更加高效、卫生的方向发展。The traditional drying equipment and folding aids in the current market are generally faced with the problems of large functional limitations and insufficient practicability, and cannot be widely used in the market and families. In view of this, a machine with drying, disinfection and folding functions was designed, with Arduino as the controller, the main frame made of aluminum profiles, and the DC motor, servo and sensors to drive the equipment to operate efficiently. The equipment realizes the drying of clothes through the heating system at the bottom, and has a built-in temperature and humidity sensor to monitor the drying process to ensure that the clothes are dry;Ultraviolet light kills bacteria and viruses on clothing. The folding link adopts a synchronous pulley mechanism to drive the hanger to carry out independent and precise movement, so as to realize the automatic identification and intelligent folding of clothes. Designed to free up manpower, users can enjoy a one-stop service from drying, disinfection to automatic folding, saving time and reducing the daily burden on users. With its efficient, hygienic, healthy and convenient characteristics, the equipment can be widely deployed in hospitals, factories and other places, promoting the development of related fields in a more efficient and hygienic direction.
