常用化学消融剂的病理学实验研究

Zhongguo shiyan zhenduanxue, 2006
目的探讨无水乙醇、乙酸和盐酸消融肝脏后的动态病理变化。方法向大鼠肝脏内注射不同消融剂后分别在不同时间段处死后取肝脏,制作病理切片,用光学显微镜观察各消融剂作用后的动态变化和各自特点。结果几种消融剂作用肝脏后均产生凝固性坏死,无水乙醇作用后的坏死灶边界不清,形态不规则,周围纤维包膜形成缓慢。乙酸、盐酸消融后坏死彻底,边界较清晰,相比之下盐酸造成组织坏死的形态更规则,边界更清晰,纤维包膜形成早且完整。结论盐酸作为化学消融剂作用类似于乙酸,但在临床应用中其安全性和可控性远高于无水乙醇和乙酸。

基于电信号的滚动轴承润滑监测实验台设计

Zhendong Ceshi yu Zhenduan
针对复杂运行工况下滚动轴承承载界面润滑状态实时监测的难题，基于接触界面电学响应特性和油膜评价理论，提出了通过施加微弱电场并监测电信号动态变化，间接表征微凸体接触面积的无损评价方法。首先，在轴承内外圈间施加稳定电场；其次，通过连续监测滚动体‑滚道间电信号的变化，间接表征承载区微凸体接触面积及油膜厚度的演变规律；然后，设计并搭建了具备多参量同步采集功能的轴承润滑状态监测实验台，将轴承动态加载与信号监测相结合，分别完成了可视化监测界面、轴承实验台和传感器高精度转换电路模块的集成设计；最后 ...
