研制了一种测量光合植物中感生叶绿素荧光的小型“考茨基仪”(Kautskyapparatus)。这个仪器的核心是由发光二极管及装在它背面的光电晶体管所构成的新的“传感器—发射器”组件(掮背式组件)。可以250μs的时间分辨率记录荧光曲线,辐照时间可以在0.1秒到100秒内任意变动,光强的变化范围可从0到10~4尔格·厘米~(-2)·秒~(-1)。与手提式记录器一起使用,新仪器提供一种可靠而快速的测量作物在自然光照下的光合活动。上述的那种掮背式“传感器—发射器”组件作为一种检测荧光和反射光的新的光电子学器件有普遍的重要性。文中举出了新仪器工作的一些实例以证实它的时间分辨率、灵敏度及其它特征。
A small Kautskya paratus was developed to measure the induction of chlorophyll fluorescence in photosynthetic plants. At the heart of this instrument is a new “sensor-emitter” assembly (backpack assembly) consisting of a light-emitting diode and a phototransistor mounted on the back of it. Fluorescence curves can be recorded at a 250μs time resolution. Irradiation time can be varied from 0.1 second to 100 seconds. Light intensity can vary from 0 to 10 to 4 erg · cm -2 (sec -1) -1 ). Used with portable recorders, the new instrument provides a reliable and fast measure of crop photosynthesis in natural light. The aforementioned backpack “sensor-emitter” assembly is of general importance as a new optoelectronic device for detecting fluorescence and reflected light. The article lists some examples of new instrument work to confirm its time resolution, sensitivity and other features.
