查询词典 light

所谓透射式是指被测物体放在光路中，恒光源发出的光能量穿过被测物，部份被吸收后，透射光投射到光电元件上；所谓漫反射式是指恒光源发出的光投射到被测物上，再从被测物体表面反射后投射到光电元件上；所谓遮光式是指当光源发出的光通量经被测物光遮其中一部份，使投射刭光电元件上的光通量改变，改变的程度与被测物体在光路位置有关。

The study shows that: evergreen broad-leaved species during the middle and later period succession have better adaptability under the different light surroundings, such as Elaeocarpus glabripetalus, Ilex integra, Photinia prunifolia, Cinnamommum camphora. And Fluorescent Characteristics also verifies the above result. The experiment results indicate that: PSⅡreaction centers of majority tree species are not marked oxidized under the full light surroundings. Photosynthetic electron transport activity can maintain highly, in this way, it is helpful to enhance radiant energy dissipation and thus dissipate excess light energy. That is to say, the increase of non-photochemical quenching coefficient can conduce to protect PSⅡ, and mitigate the effect of high light on photosynthesis.

研究发现处于演替中后期的常绿阔叶树种幼苗，对光环境的变化均有着较强的适应能力，秃瓣杜英、全缘冬青、小叶铁冬青、桃叶石楠、香樟等树种的表现尤为突出；荧光特性的研究也应证了这一观点，测定结果表明多数树种的PSⅡ反应中心并未受到明显氧化破坏，在全光照条件下仍能维持较高的光合电子传递活性，能通过提高非辐射性热耗散，消耗PSⅡ吸收的过剩的光能，从而保护PSⅡ反应中心免受因吸收过多光能而引起的光氧化伤害。

For example: peripherin-layer is made of nuphtheroquinon-xylenediol azide-anti-alcohol (microspectroscopic catalysical sensitivity range of up to 320 ~ 460nm), PS print, when you choose to use iodine gallium light, exposure time, simply by 20s with high pressure mercury lamp above the 30s, because although the two lamps and the spectral 300 ~ 460nm scope, but sulfonylated spetroscopy gallium light emission from 400 nm wavelength in close to the section of the distribution of light energy and light energy than much of high pressure mercury lamp, uniform is also much larger, and with this kind of formulation-peripherin-catalysical spetroscopy, emiting anastomasis sensitivity more productive.
