查询词典 night vision

The usual test for visual acuity, the letter eye chart, may not, however, reflect the true nature of visual loss, says the American Academy of Ophthalmology. Other tests-which measure glare sensitivity, contrast sensitivity, night vision, color vision, and side or central vision-help nail down the diagnosis.

This paper briefly reviews the operation principles and features of mechanical sight, optical sight, electrooptical sight and integrated sight. The status of mechanical sight, traditional optical sight, lowlightlevel night vision sight, new electrooptical sight and integrated sight equipped in different nations worldwide is given. The development status and parameters of various typical electrooptical sights as well as simple day and night firecontrol systems are described. It is pointed out that mechanical sight and optical sight are still necessary for future light weapons. However, electrooptical sight shall prevail in equipment procurement, and light weapon sight equipped in the future shall be the integrated electrooptical sight.

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.
