查询词典 non-polarized light

When propagating light\|ray passes through two fixed points in the gradient index mediums and a cuspidal variable\|point （at this point the trace equation of propagating light\|ray is non\|differentiable） at the borderline of two different GRIN mediums, the mathematical relationship, which the trace equation of propagating light\|ray and borderline equation of two different GRIN mediums should satisfy, is derived by the Fermat's principle and calculus of variation.

B The necessity of such light is evident from what has been said, for faith is essentially an act of assent, and just as assent to a series of deductive or inductive reasonings, or to intuition of first principles, would be impossible without the light of reason, so, too assent to a supernatural truth would be inconceivable without a supernatural strengthening of the natural light Quid est enim fides nisi credere quod non vides?

"有必要的，例如轻是显而易见的，从已经表示，为信仰本质上是一个法的赞同，正如核可了一系列的演绎或归纳reasonings ，或以直觉的第一原则，将不可能无轻的原因，所以，也赞同一个超自然的真理，就不能想象没有一个超自然加强对自然光"的回报预测单一目的的NiSi credere和非

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。

Chromatic plastic film and light conversion film has been applied in protected cultivation, and plastic films with different light quality may serve as a non-chemical approach regulating growth and thermoperiodic responses of plants. A few studies showed that light quality affected growth and yield of strawberry, but little is known about its effects on photosynthesis and chlorophyll fluorescence in strawberry leaves, and fruit quality. So it is beneficial to scientific regulating growth and fruiting for strawberry protected cultivation to study on those effects and the interactions between CO2 and N supply on photosynthesis.

而低氮影响植株生长、叶片黄化，进而影响光合作用，导致抗性减弱和产量品质下降；③CO_2供应问题：目前我国草莓栽培常在设施环境下进行，在封闭性强的设施中空气流通不畅，常导致设施内部CO_2供应不足而影响光合作用，进而影响产量和品质；④光不足与光质问题：设施栽培中，光通过玻璃和塑料棚膜后使设施内的光强与光质均发生改变，这些变化特别是光质变化对草莓生长与结果的影响程度尚无明确认识。

It is a more stupendous reformation for solid light source. Moreover, LED possesses advantages as high quality light, non-radiation and durability and low maintenance cost which other solid light source can't compare with.

除此之外，LED还具有其他优势，光线质量高，基本上无辐射，属于典型的绿色照明光源；可靠耐用，维护费用极为低廉等等。

You have to think about it like this: the light color is going to light the non occluded parts, while the dark one is going to light the occluded ones...

你必须想想这样的：光的颜色会照亮没有被遮住的部分，而黑暗是是遮住的部分变暗。。。
