以生长于不同光环境下的地木耳为材料，对其Fv/Fm的日变化、光合作用特性、叶绿素和类胡萝卜素的含量进行了研究，以了解其光适应的生理生化基础。

The results were as follows:(1) Monochromatic light in different wavelenth could induce phototaxis behaviour reaction of the CBW moth with different level. According to the response rate of it, some peaks appeared in their spectral behavior response curve, two of them were located at 483nm and 340nm, others located in 400nm,538nm and 605nm respectively. The peak response in 483nm agreed well with ERGs result.

峁允？：(1)一定时间暗适应的棉铃虫蛾对单色光和白光刺激均具有趋光行为反应，依其趋光反应率大小，其光谱反应曲线在340 -605nm波谱范围内，表现为大小较复杂的几个峰，其中两个峰分别在蓝光区483nm、紫外340nm ，另在近紫外的400nm、绿黄光区的538nm有峰。

The result is showed that the Gq α were specifically localized in the rhabdoms as the membrane-bound form and in the cytoplasm as the soluble form. The localization of Gq α changed depending on the light condition. In the dark, many immunogold particles were detected in the rhabdom rather than in the cytoplasm.

在暗适应后，Gqα主要分布于感杆束，细胞质中很少，感杆束与细胞质中胶体金颗粒的密度比为2.11±0.186；在光适应后，密度比减少为0.63±0.056；在不同波长的光照处理后，Gqα定位有差异，感杆束与细胞质中胶体金颗粒的密度比由高至低，依次为：绿光（2.38±0.179）、红光（1.99±0.177）、蓝光（1.92±0.163）和黄光（1.02±0.106）。

Experiment on adaptation effects in cat striate cortex found no pronounced difference between simple cells and complex cells.

结果显示，相对于简单的平动刺激，复杂的光流刺激引起了更显著的适应及后效应：细胞的反应在适应期间及适应后衰减程度更大，多数细胞的方向选择性在适应后发生了显著变化；总体上，细胞对复杂光流的适应具有方向选择性，但细胞对平动刺激的适应与测试刺激的运动方向无关。

These results indicated that the seedlings of Vallisneria natans were adapted to low intensity which ranged from 7.1% to 43.3% of natural light intensity.

这表明苦草幼苗有一定的低光适应能力，光强范围大约是7.1%~43.3%，为在浑浊水体中恢复、重建苦草种群提供了一定的实验依据。

METHODS:By using Vision Monitor visual evoked response imaging system,the standards for five obtained Flash Electroretinogram were recorded on 53 normal subjects (73 eyes),including F-ERG to a weak flash in the dark-adapted eye,F-ERG to a strong flash in the dark-adapted eye,oscillatory potentials,F-ERG to a strong flash in t...

应用法国Metrovision公司生产的Vision Monitor视觉诱发系统检测正常人53例73眼。F-ERG的5个标准反应，包括暗适应25dB弱光刺激时的反应、暗适应0dB强光刺激时的反应、振荡电位、明适应白色标准闪光刺激时的反应和明适应快速重复闪烁光刺激的反应。

In the lightadapted state, the distribution of the pigment ranules were mainly around the top region ofrhabdoms, however, the pigment granules distributed evenly around rhabdoms in the dark-adapted state. No difference was observed between male and female.

在光适应条件状态下，屈光器及视杆周围的色素颗粒主要分布在视杆部位的上侧，暗度适应条件状态时则较均匀地分布于视杆两侧上下；性别对色素颗粒分布无明显影响。

It is confirmed that under the illumination of light the dark-adaptedBR is quickly turned into the light-adapted, and undergoes a photo-chemical cycle then through a sequence of intermediates of J, K, L,comes into a more stable intermediate-M state. M state relaxes to B state in about one hour. B state converts completely into D state after 24 hours. B state initiates the photochemical cycle under illumination, while it can transform into D state in the dark. So B state is a key intermediate in the BR photochemical cycle.

实验证实，样品受光照激发后很快从暗适应型经过光适应型进入光循环，经过一系列的光化学中间体到达较稳定的M态。M态经过约1小时热驰豫完全回到光适应型B态，B态再经过24小时缓慢热驰豫完全回到暗适应型D态。B态受光则进入光循环，不受光则转化为D态，从而认为B态是菌紫质光循环路径中一个重要的分支节点。

They weren't aggressive, but I yelled and threw a rock in their direction to get them off the trail and away from me, just in case.

他们没有侵略性，但我大喊，并在他们的方向扔石头让他们过的线索，远离我，以防万一。
