  Hydroxyapatite (HA)-based materials have been widely used in the field of ligament tissue engineering in the past decades.It has been previously reported that HA can increase the penetration of marrow-derived mesenchymal stem cells (MSCs) and MSCs cells into scaffolds due to increased cell differentiation in biological media.Additionally, it was found that there are much difference between MSCs and anterior cruciate ligament (ACL) cells.For that reason, we mainly evaluate the biocompatibility of PET-silk scaffold with fibroblasts cells in vitro.We cultured BALB/C CL7 mouse fibroblasts cells on the substrate of PET fiber and PET-HA scaffold, respectively, and then observed the morphology by using scanning electron microscopy.Our data indicate that PET-HA scaffold has good biocompatibility with fibroblasts cells and can potentially be useful in enhancing the fibroblasts cell differentiation and proliferation.

对于热轧生产线来说,其变速、变载和工艺有别于冷轧生产线,热轧轧制过程工艺参数对于设备的振动影响较大。开展热轧生产线设备状态集中监控工作需要研究设备、工艺、故障履历、故障的可诊断性等,选择针对热性的设备监测和诊断方法。本文通过对热轧生产线设备状态把握的关键技术研究与成功实践,形成了热轧区域设备状态集中监控系统解决方案,性能指标达到国际先进水平。

针对某烧结厂烧结机栏板断裂的问题,本文采用ANSYS 有限元软件中的热-机耦合的方法,首先建立了栏板的三维实体有限元模型,在此基础上模拟了栏板在不同时刻温度作用下各部位温度场及应力场的变化,并结合栏板材料的金相组织分析,找出了栏板断裂的原因,即栏板结构的安全裕度不大,但不会引起栏板裂纹;栏板材料的石墨面积率仅为0.1 左右,球状修正系数为0,基本无球化,这是造成栏板断裂的主要原因。
将连退机组平整机1 号机架入口除尘装置进行改进,改进后的吸尘装置为22mm×1200mm 的鸭嘴形吸尘口,流速可达到25~30m/s,同时增设气动装置将伸缩滑动式吸尘口,在工作时可运动到距支承辊和工作辊相切线 20~30mm 距离,并采用波纹管降低了除尘风管的振动,充分保证除尘效果。进而解决了由粉尘造成的带钢C90 缺陷,机组速度也由原来的300mpm 提高到500mpm,一方面速度的提高增加了生

线材的捆扎在我国属于一个薄弱环节,各大钢铁企业主要依靠进口国外的自动打捆设备。自动打捆设备使用及维护缺少经验借鉴,为保证生产的顺利进行,除配置一台自动打捆设备外,高速线材生产线再配置一台半自动打捆机是目前经济的选择。现有半自动打捆机在结构和功能上存在着若干不足,为此设计了一种新型的对称挤压方式的半自动打捆机。本文主要介绍了此种打捆机的工作原理、优点、结构组成等。
