The asbestos is made of loosely bonded fibers, which can easily be separated. 石棉纤维制成保税松散,容易遗失。
But when asbestos fibers get old and break, tiny particles can drift into the air. 但是当石棉纤维老化断裂,很多微小颗粒能够漂浮在空气中。
The body's immune system is able to process and breakdown some of these asbestos fibers, but invariably many still remain. 机体的免疫系统可以处理和分解一部分石棉纤维,但是常常大部分还是存留下来。
In essence though, pleural mesothelioma develops when jagged asbestos fibers are inhaled and settle in and around the lungs. 本质上,当石棉纤维被吸入并在肺内或周围持续存在使得胸膜间皮瘤发展。
The mineral fibrous dusts partly become asbestos plaques and partly become naked fibers after being injected into animal bodies. 石棉纤维粉尘注入动物体内后,一部分形成石棉小体或石棉斑,一部分仍为裸露纤维。
The injuries done by chrysotile asbestos fibers to creatures include not only those of general fibers but also those of the amorphous SiO 2 phase. 纤蛇纹石石棉纤维对动物的危害,既具有一般纤维的危害性,又具有非晶质SiO2的危害性。

Introduce the manufacture, performance and application of new braking materials without asbestos fiber and other fibers. 介绍既不用石棉纤维也不用其它纤维的新型无石棉制动材料的制造、性能及应用。
In China, asbestos resource is rich and all kind of asbestos can be seen, however asbestos fibers exceed over Chinese National Standard ( 2mg/ m3) commonly in the private enterprises and abnormity workshops. 我国石棉资源丰富、品种齐全,但个体作坊或不规范的生产车间石棉粉尘含量常超过国标(2mg/m~3),因此石棉仍然威胁我国接触工人健康的一种潜在性致癌因素。
The formation of asbestosis and pleura spot is related to the physical stimulation of asbestos fibers in some way; the development of lung cancer results from not only the stimulation of asbestos fibers, but also the cancerigenic substances absorbed on the surface of the fibers. 石棉肺及胸膜斑的形成与石棉纤维的机械性刺激有一定关系,肺癌的发生除与石棉纤维的机械性刺激有关外,还与石棉纤维表面吸附的强致癌物有关。
A Study of DNA Damage Induced by Asbestos Fibers in Vitro 石棉纤维诱发8-羟脱氧鸟苷导致DNA损伤的体外研究
And asbestos tailing is cube-shaped particles, rough superficial texture, alkaline and contains some short and small asbestos fibers, etc. These characters play remarkable role to make asbestos tailing and asphalt mixture show good pavement performance. 石棉尾矿的颗粒呈立方体状、表面纹理粗糙、呈碱性以及石棉尾矿中含有部分短小石棉纤维等特点,对石棉尾矿沥青混合料表现出良好的路用性能起到显著作用。
