查询词典 light on

HE WISHES FOR THE CLOTHS OF HEAVEN Had I the heavens' embroidered cloths, Enwrought with golden and silver light, The blue and the dim and the dark cloths Of night and light and the half-light, I would spread the cloths under your feet: But I, being poor, have only my dreams; I have spread my dreams under your feet; Tread softly, because you tread on my dreams.

We found out one kind of new orange-red long afterglow material La2O2S: Eu3+, Mg, Zr.2 In the phosphor Gd2O2S, Mg, Ti which was prepared by high-temperature solid-state method, the orange afterglow phenomenon can be seen after illuminated with UV light.3 Using the high-temperature solid-state method, Gadolinium oxysulfide phosphors doped with rare earth ions were synthesized. We can observe the red or orange phosphorescence in Gd2O2S doped with Eu3+, Sm3+, Tm3+, Yb3+, Dy3+, Er3+, Nd3+or Ho3+. This is a new result of the long afterglow phosphors research.4 Using the microwave radiation method, the new Sm3+ doped gadolinium oxysulfide phosphor, which has the orange-red long afterglow emission after illuminated with UV light or visible light, was synthesized for the first time.5 In fluorescent materials YOX doped with europium ions, the long afterglow phenomenon wasnt observed but the blue luminescence of Eu2+ and red luminescence of Eu3+ are simultaneously examined. This is a new result of the valence stability and change of Eu2+ in yttrium oxyhalide .We systematically studied the effects of the host, addition agents and reaction atmosphere on the valence change and fluorescence property of europium ions.

Look downward on that Globe whose hither side With light from hence, though but reflected, shines; That place is Earth the seat of Man, that light His day, which else as th' other Hemisphere [ 725 ] Night would invade, but there the neighbouring Moon (So call that opposite fair Starr) her aide Timely interposes, and her monthly round Still ending, still renewing through mid Heav'n, With borrowd light her countenance triform [ 730 ] Hence fills and empties to enlighten th' Earth, And in her pale dominion checks the night.

你往底下看那个球吧，它的这半边只是反射，是从这里照过去的光。那就是人所住的地球，光的是昼，相反的暗的半球是夜。他的邻近就是地球对面那美丽星球，名字叫月亮，定时帮助他，在半空中，每月绕他转一周，循环往复，从这里借去的光照耀着大地，依照盈虚圆缺、嫦娥三相的形式照亮着地球，在她苍白的领域内控制着夜。

From the level of science, the light we saw is the reflection on objects, and that are not the objects themselves. The space that we apperceived from the vision is the result of the interaction between the light and objects, therefore, there is some internal relationship between the light and objects, which means there is correspondence between them.

从科学意义上讲，我们看到的是光线在实体上的反射，而非实体本身，我们视觉感知的空间是光线与实体相互作用的结果，因此光与实体存在着某种内在的联系，也就是说，光与实体存在着对应性。

RESULTS: In the retinal region without light, the structure of every layer was clear, cells in neuroepithelial layer arrayed in rule, some bubble presented in external granular layer and internal granular layer, RPE cells were compact, and the color of pigment article was coincident. In the region with direct blue light and that with 30J/cm2+Acrysof one-piece/ pMMlA, cells on photoreceptor and external granular layer were lost partially, bubble increased, RPE cells were with different sizes, and cell edema, cell lost and pigment article cluster could be seen.. In region with 30J/cm2+Natural, a little disorganization could be seen comparing to that without light, but more normal than those with Acrysof and direct eradia tion.
