The oligomeric states of PSⅡcomplex in soybean leaves treated with moderate light (700μmol〓) and strong light (2000μmol〓) were studied by nondenaturing PAGE and gel filtration chromatography. The following results were obtained. PSⅡ dimers resolved by nondenaturing PAGE accounted for about 75% of total PSⅡ complexes and there was no significant difference in the ratio of PSⅡ dimer to monomer between samples from moderate light-treated and fully dark-adapted leaves.

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.

结果：未照射部位：视网膜各层次结构清晰，神经上皮层内各细胞排列规则，整齐，RPE细胞排列紧密均匀，色素颜色一致；单独光照和透过Acrysof一片式I0L：光感受器层部分细胞丢失，外核层可见固缩核，浓密，内颗粒层细胞大量丢失，内丛状层内空泡明显增多，RPE表面，细胞大小不均，可见肿胀、缺失，细胞内色素浓密、聚集成块；透过Nat-ural一片：与未照射处相比，视网膜各层次结构仍有部分破坏，但程度明显减轻。

However, the achenes are light sensitive. They can germinate in very low light intensity and even can germinate in far red light.

三种植物的种子都是光敏感种子，它们在很低的光强下，甚至在远红光下均能萌发。

It is considered in this paper that the light and heat oxygen resistance ageings of silicone acrylate resin are better than those of normal acrylic and polyurethane resins, through the theoretic investigations into the reaction mechanisms of the light and heat oxygen ageings of high molecular polymer and contrasting, when exposed to light and under a high temperature, the changes in colour,shape, tensile strength and elongation of Silicone Acrylate Resin DX 8501 to the normal acrylic and polyur...

本文通过对高分子聚合物的光氧老化、热氧老化的反应机理的理论探讨和对DX8501硅丙树脂、普通丙烯酸树脂、普通聚氨酯胶膜在紫外光照射下和高温条件下的颜色、形态、抗张强度、伸长率的变化情况对比，认为硅丙树脂的耐光氧老化和耐热氧老化的性能优于普通的丙烯酸树脂和普通的聚氨酯。表3，参考文献8

The effect is: the work is based on requirements (light-colored tune) program designed, left the bedroom is designed for young couples, using the gray deployment white bedspreads, and light yellow light zone, the entire room is clean clean, in the local table near the window is based on the romantic atmosphere and set!

大意是：该作品是根据要求而设计的方案，左卧室是为年轻夫妇而设计的，运用了灰色调配上白色的床罩，加上浅黄色的灯带，整个房间显得清新干净，在靠近窗台的地方桌子是根据浪漫的情调而设置！

Phytochrome 3 (PHY3) is a novel chimeric photoreceptor that can respond to both red/far red and blue light. Using this photoreceptor, some cryptogams could enhance light sensitivity under low light environment.

Phytochrome 3 (PHY3)是一种特殊的既能吸收红光/远红光又能吸收蓝光的嵌合光受体，一些隐花植物利用 PHY3 提高在弱光环境下的光敏感性。

The response of TiO2 to light was expanded to visible region by dopping metal or metal compound. Some small compound could be degraded by dopped TiO2 under visible light irradiation and also the degradation of dye under visible light could be accelerated.

通过搀杂金属或者金属化合物将TiO2光响应范围扩展到可见光区，使得小分子化合物在可见光下得到降解，同时可以使得染料在可见光下的降解速率加快。

The invention adopts a semiconductor laser or other pumping lights, such as a LED light, to pump the etalons, optical elements and wave plates made of optical materials which can absorb the pumping light, and regulates the output power of the pumping light to change the temperature of transmittance zones of the etalons, wave plates and optical elements so as to realize the changing of transmission wavelength of the etalons, the quick changing of wave plate phase and the quick changing of optical length of optical elements.

本发明采用半导体激光或其他泵浦光如LED光泵浦由可吸收泵浦光的光学材料制作的标准具、光学元件、波片，由调节泵浦光输出功率改变标准具波片、光学元件透光区域的温度，从而实现标准具透过波长的改变、波片相位快速变化，光学元件光学长度快速变化。

蓝色部分的星光来自伴星，是一颗B型星；黄色部分星光来自明亮的主星，是一颗F型星。

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.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.
