炭黑尘肺是危害健康的职业病之一。为了使工人免受炭黑粉尘的危害,需研究炭黑粉尘浓度与炭黑尘肺的发病关系。这一工作需要大量的动物实验才能完成。由于炭黑粉尘的特性,易吸附成团不宜采用气管注入法染尘,而宜用自然吸入染尘法。为此,需要一套对粉尘浓度能加以控制的特殊仪器和设备,特 Carbon black pneumoconiosis is one of the health hazards of occupational diseases. In order to protect workers from the hazards of carbon black dust, it is necessary to study the relationship between the carbon black dust concentration and the incidence of carbon black pneumoconiosis. This work requires a large number of animal experiments to complete. Due to the characteristics of carbon black dust, easy to adsorb into the group should not be tracheal injection of dust, but should use natural inhalation of dust. For this purpose, a special set of instruments and equipment that can control the dust concentration is needed
