1 Photic stimulation increases the occurrence of spike, or spike and wave, discharges in some patients with generalized epilepsy.

2 Keep track of what photic, adjustable surface and the darkened face.

3 Most marine plants can live only in the photic zone.

4 MethodsThe principle of the comparison of the photic intensities that the two photoresistors incept is adopted, and is combined with precise data processing.

5 PURPOSE: In search of the mechanism for photic retinal injury.

6 The creep strain of nonwoven geotextiles is measured by using the method of photic leverage.

7 It will be better if metal modified apatite is covered by photic organic film substantially.

8 Coenzyme Q10 plays an important role in preventing the photic injury of retina and optic cell apoptosis.

9 Conclusion: electro - acpuncture is one kind of nonphotic zeitgeber . It may modulate the phase - shifting of photic stimuli.
