煤灰熔化物的结晶体

锅炉技术 1990年第2期21卷 28-37页

作者： D P Kaemanorifch j.williamson 舒宜上海锅炉厂研究所

一、前言灰沉积的产生在燃煤锅炉内能引起严重的运行问题及降低热效率,这些沉积的形状从脆性脱落、轻微烧结沾污至稠密半玻璃态的结渣。电站镉炉设计师和操作者用多种方法确定不同设计准则或灰沉积形态的可能性(结渣倾向),这些方法中最... 详细信息

一、前言灰沉积的产生在燃煤锅炉内能引起严重的运行问题及降低热效率,这些沉积的形状从脆性脱落、轻微烧结沾污至稠密半玻璃态的结渣。电站镉炉设计师和操作者用多种方法确定不同设计准则或灰沉积形态的可能性(结渣倾向),这些方法中最主要的是标准的灰熔化试验。

粉剂及粘性聚合物的动力密封

化工设备与管道 1988年第1期 51-53页

作者： j.williamson 陈震湖南湘潭大学

在橡胶、塑料工业中,由于环境的苛刻和条件多变,动密封成了一个十分棘手的问题。在这方面,不论间歇或连续运转,典型的例子是混合器的密封。该密封装置必须能适应粉剂和粘性聚合物两种物料状态。本文将介绍用于混合器上的最常用的几种密... 详细信息

1.引言影响玻璃体血块清除的因素很多玻璃体凝胶与液体血液存在相差,所以凝聚很快,而不易溶解;(2)玻璃体纤维蛋白溶解(以下简称纤溶)活性很低,其血块清除与“一般的清除机制”不同;(3)玻璃体血块不足以刺激炎症细胞反应,而致非纤溶性清... 详细信息

1.引言影响玻璃体血块清除的因素很多玻璃体凝胶与液体血液存在相差,所以凝聚很快,而不易溶解;(2)玻璃体纤维蛋白溶解(以下简称纤溶)活性很低,其血块清除与“一般的清除机制”不同;(3)玻璃体血块不足以刺激炎症细胞反应,而致非纤溶性清除机制活性受到抑制。因此,玻璃体内未溶解的血块经老化退行性变,形成胶原—血块凝集的致密膜。目前人们对非纤溶性炎症细胞活性和纤溶酶介导的纤溶情况在玻璃体血块清除中的作用,尚未取得一致意见。本文力图通过实验,较全面地探讨纤溶和玻璃体血块溶解清除之间的关系。

Traumatic brain injury(TBI)is a public health problem with an undue economic burden that impacts nearly every age,ethnic,and gender group across the globe(Capizzi et al.,2020).TBIs are often sustained during a dynamic range of exposures to energetic environmental forces and as such outcomes are typically heterogeneous regarding severity and pathology(Capizzi et al.,2020).
