Effects of different stimulus frequency and intensity on rat light adaptation flicker electrophysiology;

By using the method of continuous polarization interfering,we have measured birefringence dispersion curve and intensity transmission curve of quartz between 300 nm and 800 nm.

A testing method and system of homogeneity of high-power plane-array laser s output light pane (including intensity and spectrum distributing homogeneity) was presented.

Effect of nitrogen sources and light intensity on the absorption and accumulation of phenanthrene in cucumber seedlings;

Effect of light intensity and light quality on growth and total flavonoid accumulation of Erigeron breviscapus;

Leaf photosynthetic characteristics and its response for light intensity of three species of Dendrobium Sw.in Huoshan County;

An analysis for the intensity of light and diffraction angle of bright fringes of the single -slit Fraunhofer diffraction is developed from qualitative to quantitative discussion,basing on the method of Fresnel s half-band and its extention,and on the obrvation for the amplitute vector features of wave band and sub-band on screen.

In the course of testing, the laser was used as light source with twin-light path, dispelled the error of light-intensity variation of traditional detection devices, the measurement result only relates to the relative change of optical intensity.
