Textiles - determination of smoke density - light extinction method 减光系数法
Measuring method of smoke density using light extinction method 用光衰减法检测烟浓度的测量方法
Textiles . determination of smoke density . light extinction method 纺织品烟浓试验测定减光系数法
So the third chapter focuses on the measuring system . the operating principle ( light extinction method ) , the factors which influence the result and the resolvent to avoid them are explained . the experimental procedure is also introduced 第三章对此磁致偏振特性测量系统的搭建及工作原理(消光法) 、影响测量结果的因素及解决方法、实验操作步骤等作了说明。
