由北京地质仪器厂和天津南开大学物理系共同研制的 CCF-Ⅰ型肺磁仪已通过鉴定。用此仪器对肺磁场进行检测,是一种新的劳动卫生监测技术,可用以探索尘肺病的早期发现方法。该仪器具有以下特点:1.抗干扰能力强由于肺磁场比较弱(10~(11)—10~(-7)T),而城市环境噪声很强(10~(-8)T 以上),地磁场更强(0.5×10~(-4)T),故肺磁场被背景场所掩盖。本仪器采用一
The CCF-Ⅰ lung magnetometer jointly developed by Beijing Geological Instrument Factory and Tianjin Nankai University Physics Department has passed the appraisal. Using this instrument to test the magnetic field of the lung is a new labor hygiene monitoring technique that can be used to explore the early detection of pneumoconiosis. The instrument has the following features: 1. Strong anti-interference ability due to weak lung magnetic field (10 ~ (11) -10 ~ (-7) T), and strong urban environmental noise (10 ~ (-8) T above) The geomagnetic field is stronger (0.5 × 10 -4 T), so the lung magnetic field is covered by the background. This instrument uses one
