4) oil mist concentration
油雾浓度
1.
To monitor the concentration and composition of oil mist,a method for collecting oil mist with solution adsorption and monitoring oil mist concentration with gas phase chromatograph was put forward.
机械加工车间空气中油雾颗粒以1μm左右的气溶胶形式存在,为了检测其油雾的浓度和油雾的组成成分,提出了溶液吸收富集采集油雾和气相色谱法检测油雾浓度的方法,并用该方法检测了某机械加工车间空气中油雾的浓度。
6) concentration transmitter
浓度变送器
1.
In order to resolve the unsteady concentration control brought by the pulp flow fluctuation due to valve operation, a new concentrationcontrol method is put forward based on the measurement of the increment relation between the concentration value and valve opening afteranalyzing the operation mechanism of the valve and concentration transmitter.
为了解决由于阀门动作引入的流量变化导致的浓度控制不稳定的问题,在分析阀门、浓度变送器工作机理的基础上,提出了基于测量浓度值和阀门开度之间增量关系式的浓度控制方法。

γ射线报警器
γ-ray alarm
丫shexian bQo)ing单Y射线报警器(v一ray alarm)监测v辐射水平的核辐射剂量探测仪器。通常安装在具有防化设施的工事内,在预定的Y辐射阂值下报警并能测量工事外表探头附近的Y照射量率,是工事核防护设施专用配套设备。Y射线报警器一般由探头、电缆和操纵箱等部分组成(见图)。探头固定在工遍残 y射线报警器事外部,操纵箱放置在工事头部三防值班室内,并与联动装置相连接。当探头所处位置的v辐射强度达到仪器报警阂值时,处于预报状态的报警器,由探头将接收的v辐射转换成电脉冲信号,经过整形放大,由电缆传送到操纵箱。信号在操纵箱内分成两路:一路经直流放大后推动报警电路工作,使仪器立即报警,发出声光报警信号,同时送出一个控制信号给联动装置,对工事的防化设施进行自动控制;另一路信号由人工控制,经积分电路到电表指示器,测量工事外表探头所在位置的Y照射量率。 (王立银)
