By making pre-tests,acute reaction tests and subacute reaction tests on animals using aluminized glass fibers and ordinary glass fibers,the influence of glass on human body is investigated,coming to a conclusion that glass fibers contain no free silica and are therefore inert and non-toxic to living things.
通过用镀铝玻璃纤维和玻璃纤维对动物进行预试验、急性反应试验和亚急性反应试验,分析了玻璃对人体的影响,得出玻璃纤维中不含有游离二氧化硅,因此对生物是惰性的无毒的等结论。
Object:To evaluate shear bond strength between self-made Alumina-Glass Composites (AGC )and the effect of different surface treatments on the combining strength.
目的:测试自制氧化铝玻璃复合体(AGC)和Vitaalpha不透明牙本质瓷的结合强度,探讨AGC不同表面处理对结合强度的影响。
