Photometers are specifically designed to measure emitted, reflected or transmitted light in photometric terms of luminous flux, luminance, illuminance or luminous intensity.
光度计是专门用于测量发射，反射或透射光的光通量，亮度，照度或发光强度等。

Its separated performance is usually reflected by the flux and retain rate. concentrating and penetrating token the operator schema.
其分离性能通常由透过通量和截留率表征，而操作模式则可分为浓缩和渗透两种。

Change of heat flux and temperature distribution along furnace height with varying furnace conditions can be reflected in the model.
